Marley FAQ

In addition to the 90° corners, Marley also has 135° corners in RG 100/125 in its range. These can be used for an 8-cornered gazebo. If other angles are required, these can be ordered from your local DIY store using the order form for special corners.

Special corners with different degrees (< 90°) are available for all Marley gutters. The angle of the roof pitch can also be taken into account.

This will not hold and the bonding will break after a short time. That's why we weld the special corners.

No, the bonding is a "cold weld" and can no longer be removed. It can only be separated mechanically by sawing it off.

The cleaner is not used to remove dirt, it is intended to make the surfaces to be bonded free of grease. The gutter adhesive can then penetrate the plastic better and achieve optimum bonding (cold welding) of the gutter and the connecting shell.

Do not use below +5°C.

The semi-circular gutter is a pure plug-in system and must not be glued. If it were glued, there would be no controlled linear expansion and therefore no deformation or similar.

No, the size of the downpipes, like the size of the gutter, depends on the roof area, so it is not necessary to reduce or extend a downpipe.

Yes, the gutters can be painted with Dulux Seidencolor or Glanzcolor, for example. Priming is necessary beforehand. The recommendations of the paint manufacturer must be followed. Save yourself this time-consuming work and buy Marley guttering in special colors.

The z-shaped bracket can be bent.

All possible malfunctions, causes and solutions can be found here.

The symbols are called square and triangle. They describe the precipitation rate in mm/h when the sprinklers are arranged as a square or triangle, with a sprinkler placed in each corner. The classic square pattern is relevant for domestic gardens, while the triangular pattern is mainly used in agriculture.

Marley smart&green irrigation technology offers you the Hunter® PGJ geared pop-up sprinkler and the Hunter® spray sprinkler. Geared sprinklers are used in areas where sprinkler spacing of 8 x 8 m and larger is possible. Spray sprinklers with a fixed sector are used in correspondingly smaller areas. The sprinkler spacing between geared sprinklers should be between 8 and 12 meters. The sprinkler spacing between spray sprinklers should be between 3 and 5 meters. Maintaining these distances creates the necessary overlap of the sprinkler circuits to ensure even water distribution. Different sprinkler types should not be used within the same area.

The flow regulation allows the pressure differential between the inlet and outlet of the water to be equalized. This allows the membrane to close properly when the valve is switched off and prevents the water from running unnecessarily into the next pipe.

The HC Water Computer 601i-E has a detection function for faulty water flow and informs you of this fault via the app.

The HC Water Computer 601i-E has a detection function. As soon as the current deviates, the app informs you of this fault.

With the X-Core watering computer, you have the option of setting your own three programs in terms of start time, duration and days. It makes sense to define the irrigation zones according to the needs of the plants. You then set up the three programs, e.g. A for the lawn, B for the plant bed and C for your vegetable and herb corner. In this way, the plants are watered according to their needs. The corresponding program is then assigned to the solenoid valve via the computer programming.

1. Turn the tap or pump of your system on full.
2. Measure the time until the bucket is filled with 10 liters.
3. Use these values to determine the output of your system in l/min.
4. Rule of thumb: The faster the bucket is filled, the more sprinklers can be operated simultaneously.
5. Add up the water requirement of the planned sprinklers (see operating data for the respective items). If the added water requirement is equal to or less than the capacity of your system, you can operate all sprinklers simultaneously on one irrigation circuit.
6. Otherwise, it is advisable to simply create several separate watering circuits and open or close them individually as required using stopcocks or automatically with solenoid valves.

If you have wrapped Teflon tape around the thread, remove it and wrap new Teflon tape between 10 and 15 times around the thread. This should seal the connection.

Ask your local authorities whether a permit is required to install an irrigation system and what type of backflow protection is required in your area.

The backflow protection ensures that no wastewater can flow back into the building from the sewer system in the event of a backflow. This protection is required by law and must also be taken into account when watering the garden.

If all zones or solenoid valves were to be activated at the same time, the water pressure would drop significantly and could therefore lead to limited functioning of your system. For this reason, all segments are activated one after the other. The time offset depends on the respective watering duration.

No, you can only fit one extension, it is not possible to raise it further. The floor drain must be placed higher, there is no other option.

The cause is a lack of ventilation in the relevant pipe section. The air can only escape with difficulty or not at all. If the local conditions allow it, you can create additional ventilation or drill a 2-3 mm hole in the middle of the cover as an immediate measure.

Yes, every backwater valve, whether single or double, should be checked at least once every six months. In case of dirt and residue: Remove cover, clean parts, check seals and replace damaged parts. We recommend a complete inspection at least every 12 months.

Yes, but you should replace the seals. Seals for negative pressure can be obtained from the respective supplier of the central vacuum cleaner systems.

HT pipes are made of PP (polypropylene), this plastic is resistant to hot water up to 90°C. KG pipes are made of PVC (polyvinyl chloride) and are temperature-resistant up to 60°C.

HT pipes are made of PP (polypropylene), this plastic cannot be permanently bonded.

The single and double backwater valves may only be installed in pipes with faecal-free wastewater.

Marley pipe aerators ensure pressure equalization in the event of negative pressure in the wastewater pipe system and thus prevent siphons/odour traps from being sucked empty. When depressurized, the pipe aerator is closed and sealed. No odor nuisance! In a detached house, at least one ventilation pipe must be installed above the roof! The pipe aerator does not replace main ventilation above the roof!

KG pipes (basic sewer pipe, color orange) are only approved for laying in the ground, the smallest diameter is DN 110. HT pipes (high temperature, color grey) are only approved for the waste water pipe in the house.

It is not sufficient to use only a two-core cable, i.e. continuous current (L) and neutral conductor (N), to use the run-on function. There must be at least one switching current (L1), one continuous current (L) for the overrun and the neutral conductor (N). Earthing (earth) is not required for the fans. Always refer to the wiring diagram in the installation instructions supplied with each fan.

The distance from the point at which the air is extracted to the point at which the air is discharged into the open air is referred to as the conveying or travel distance. All fans have an indication of the conveying or travel distance. This should not be exceeded under any circumstances, as otherwise the performance of the fans will be greatly reduced.

Yes, the Marley overrun relay CS3-1B must be installed in the power supply.

Yes, the timer replaces the switch in this case. The P11 and P14 fans must be connected with switching current, continuous current and neutral conductor.

No, speed control is not provided for the fans.

No, speed control is not provided for the fans; a switch must be fitted otherwise the electronics will not work properly.

The "+" and "-" buttons must be pressed simultaneously for at least 3 seconds. The power level can then be changed by pressing the "+" or "-" button.

As soon as you start up the P12, it can run for up to half an hour, during which time the reference value for the humidity is determined. It is therefore also important that you wait until the fan switches off and only then set the speed!

To reset the P12, you must disconnect it from the power supply for approx. 45 minutes.

Yes, the P11 fan is a continuous runner that runs 24 hours a day without interruption. As a result, it provides basic ventilation in accordance with DIN, regardless of the user, and delivers 10 m³/h of air at the lowest level with a power consumption of only approx. 1.1 watts.

No, the device is not defective, apart from the colors of the cables, you need at least a 4-core cable. The continuous current is connected to terminal L, the switching current to terminal L1 (or SWL/TS/T) and the neutral conductor to terminal N. Earth is not required. Earth is not required.

We do not recommend speed control, as the performance of the fans will be greatly reduced.

This is not recommended, as the pipe resistance increases considerably. The exhaust air duct should always have the same diameter as the fan.

No. Marley fans are designed for indoor use only.

The maximum temperature for the fans is 40°C. The fans are designed for living rooms and must not be installed in ovens or sauna cabins.

Each fan is supplied with a connection diagram, which also specifies the cable cross-section and the number of cables. For a simple fan with switch and without overrun, at least two connection cables (continuous current L and neutral conductor N) must be used. For a fan with switch and overrun, at least three connection cables (switching current L1, continuous current L and neutral conductor N) must be used. Earthing is not required for the fans. Please note: The connection must be carried out by a specialist.

You can choose from the following settings during installation and operation:

1. Run-on from 0-20 minutes
2. Stop after burst ventilation
3. Stop after impulse ventilation and after-running
4. Switch to basic ventilation after shock ventilation
5. After shock ventilation and run-on and then switch to basic ventilation
6. Trigger automatic shock ventilation between 40-95% adjustable humidity threshold.
7. Automatic operation by automatic humidity control or manual operation by switch

It is not sufficient to use just a two-wire cable, i.e. continuous current (L) and neutral conductor (N), to use the run-on function. There must be at least one switching current (L1), one continuous current (L) for the overrun and the neutral conductor (N). Earthing (earth) is not required for the fans. Always refer to the wiring diagram in the installation instructions supplied with each fan.

All fans have an indication of the conveying or travel distance. This should not be exceeded under any circumstances, as otherwise the performance of the fans will be greatly reduced.

Yes, the timer replaces the switch in this case.

No, speed control is not provided for the fans. Only with the P11 and P14 can the speed be set on the fan. The design of a dimmer is not suitable for speed regulation.

No, a switch must be fitted, otherwise the electronics will not work properly.

Yes, all you need is a switching current and a neutral conductor and the small red switch on the circuit board must be set to "off".

The fans have a transparent sealing foil on the back, which is comparable to the function of a non-return flap.

ACL = continuous current, T = switching current and ACN = neutral conductor. The corresponding current must be present at all terminals if the fan is operated with switch and overrun.

The small red switch on the circuit board must be set to "on". Furthermore, the fan must be supplied with continuous current, switching current and neutral conductor.

No, the device is not defective, apart from the colors of the cables, you need at least a 4-wire cable. The continuous current is connected to terminal L, the switching current to terminal L1 (or SWL/TS/T) and the neutral conductor to terminal N. Earth is not required. Earth is not required.

We do not recommend speed control, as the performance of the fans will be greatly reduced.

Please note: The connection must be carried out by a specialist.

The fresh air heat exchangers, which are operated in pairs, work in a balanced manner, i.e. the same amount of fresh air is conveyed into the home as stale air is conveyed outside. For room air-independent fireplaces, the permissible negative pressure corresponds to 8 Pa (in accordance with DIN 1946-T6). The chimney sweep responsible for the fireplace is responsible for assessing whether an additional pressure switch must be installed. For room air-dependent fireplaces, the permissible negative pressure is 4 Pa. In this case, you must install a pressure monitor that switches off the ventilation system if the pressure exceeds 4 Pa. Here too, your chimney sweep has the final say. However, the incident also plays a major role in the assessment. The size of the building, the tightness of the building and the amount of air flowing in through the defective heat exchanger must be taken into account. For further information, please contact us using our contact form.

No, under no circumstances! The rubber coating on the ceramic body would peel off. How to clean the ceramic body/heat exchanger insert is described in the operating/assembly instructions in Fig. 53.

In the Marley online store in the "Spare parts" section, where you can also find e.g. external grille, ceramic block, filter cartridge, remote control, etc.

The "error" only occurs in single operation, namely when the small red switch on the circuit board is set to "on". The small red switch is located under the cover at the bottom left. The switch must always be set to "off" in individual operation.

No, the fresh air heat exchanger is only suitable for horizontal installation. Ensure a 2% gradient to the outside when installing.

Switch off the fresh air heat exchanger once and then reconnect it to the remote control. See operating/installation instructions Fig. 31.

The battery (CR2016 button cell) in the remote control is flat and should be replaced.

Yes, if there is at least 30-40 cm clearance to the ground/excavation floor on the outside. Please check the fleece in the external grille regularly.

No, there is no humidity or temperature sensor built into the fresh air heat exchanger and the heat exchanger itself cannot be retrofitted with one.

A 3V CR2016 lithium battery.

No, the remote control is required to switch from one power level to the next or to switch the appliance on.

Yes, all fresh air heat exchangers manufactured after August 2016 (see date sticker on the circuit board) can be controlled using a timer. This is not possible with older fresh air heat exchangers.

Pressing the "Summer mode" button switches the heat exchanger down to level I. In individual operation, the heat exchanger then only conveys stale air out of the building/room; the motor no longer switches over. In dialog mode, both devices switch down to stage I, one heat exchanger conveys stale air out of the building/room, the second device conveys fresh air into the building/room. Even in dialog mode, the direction of operation is not switched. If the "Summer mode" button is pressed again or the +/- buttons are pressed, the function is ended. The desired output level can be set by subsequently pressing the +/- buttons.

In principle, it can be used in damp rooms without any problems. If the focus is on heat recovery, please set the fresh air heat exchanger to level 3 during and after showering. If the desire for the fastest possible dehumidification prevails, a conventional exhaust air fan is more suitable.

With its DIBt approval, the MEnV 180 device also meets the requirements of the EnEV, which stipulates a maximum permissible leakage of 5 m³/h with a pressure difference of +/- 10 Pa. The fresh air heat exchanger is considered a "hole" in the building envelope and must be sealed airtight on site, e.g. with foil, before the "blower door test" is carried out - please remove the inner cover and seal the closure.

No, the preheated ceramic element heats the fresh air sufficiently so that no fresh air with sub-zero temperatures enters the living area.

No, the appliance can be operated in winter.

Basically not, but the appliance can be reinstalled with an appropriate attachment to be provided by the customer.

Yes, an extension set (max. 66 cm) is available for these applications and can be ordered as an accessory in the Marley online store.

Yes, after thorough cleaning of the surface, apply plastic primer, main coat and then clear coat.

The filter should be cleaned or replaced every 6 months in accordance with the installation instructions. The main pipe and the ceramic body should also be cleaned. All parts to be cleaned can be easily reached from the inside.

No, one remote control is intended for a maximum of one pair of appliances.

One MEnV180 is sufficient for approx. 20 m² - ideally, 2 devices should always be linked together (operation in pairs). If the fresh air heat exchangers cannot be arranged in the same room, air coupling across 2 rooms must be ensured.

First check the input voltage of 230 VAC using a multimeter (voltmeter) or similar. If this is present, disconnect the device from the power supply for approx. 1 minute. Then pair the remote control with the device again: To do this, simply press the "+" and "-" buttons simultaneously for approx. 10 seconds. The fan should now start automatically and the pairing is complete. If the green LED on your remote control does not light up, the battery must be replaced before pairing.

Yes, the aluminum composite pipe is available for both systems in diameters of 16, 20 and 26 mm. The pipes are tested and approved for both systems and comply with DVGW regulations.

Every pipe end that is installed must be calibrated. This involves not only "rounding" the pipe again, but also chamfering it on the inside and outside. This bevel on the pipe end is necessary so that the seals in the fitting are not pushed out of their seat and damaged during the insertion process (see AquaStec installation instructions). Otherwise this would result in water damage. Tip: Use the calibration tool from the Marley AquaStec range!

Yes, the drinking water pipe can be connected directly to electronic instantaneous water heaters. When connecting to a hydraulic instantaneous water heater, a metal pipe with a length of at least 1 m must be placed in between.

Yes, a pressure test must generally be carried out by a specialist company after installation! If water damage occurs, you may not be covered by your household contents insurance.

AquaStec can generally be used for the heating system, but please note the maximum flow rate of the different pipe cross-sections.

The pipes of the cold water system are designed for an operating pressure of up to 12.5 bar at 20° C.

No, the system and the seals are not suitable for compressed air.

Your sealing ring (O-ring) is probably not in the right position. Unfortunately, this often happens when the union nut on the fitting is slightly loosened and you then try to insert the pipe into the fitting.

1. cut the pipe with scissors for plastic pipe.
2. screw on the fitting - push the union nut, clamping ring and seal onto the end of the pipe.
3. push the pipe end into the fitting as far as it will go.
4. hand-tighten the union nut - ready and tight!

All folding doors always have a serrated pattern when closed. If the door is pulled smooth, the soft PVC joints are destroyed.

Ideally once a year, or when the door no longer glides as well as it did at the beginning.

With a soft cloth and mild household cleaners. Do not use scouring cream!

With a fine-toothed saw and by hand, not with a circular saw!

Yes, the sawing is done before the pieces are glued on.

Take a wide wooden or plastic wedge and press it between the rail and the wall or door lining so that the rail can be easily lifted off. Start at the bottom with the rail into which the lock profile goes, then on the opposite side and finally the top sliding rail.

No, you simply need two single doors and install them opposite each other on the sides of the frame. However, only the President and the NewGeneration are suitable for this due to the design of the closing device.

Because Marley deliberately avoids such a "tripping hazard". In addition, Marley doors are so technically sophisticated that a floor guide would not improve their functionality.

No, then the flaps inside the DUO will no longer open and close.

Yes, with the 150 x 80 mm flat duct, with a maximum of 1 m flat duct for both supply and extract air.

HT pipes are best suited as they are temperature-resistant up to 90°C and have smooth walls on the inside. This considerably reduces the pipe resistance. This is followed by the Alu-Flex hose.

No, this would destroy the entire balance of the ventilation. Only a normal grille or one with a cord can be installed.

With open fireplaces in combination with extractor hoods, carbon dioxide and monoxide may be drawn in. To prevent this, the responsible district chimney sweep must specify which safety devices must be installed. With the DUO exhaust air and supply air system, a small negative pressure is created in the room, as the supply air damper opens first. As much depends on the local conditions, which we do not know, only the responsible district chimney sweep can provide you with information on what needs to be installed.

The flexible hose with spring wire spiral is the cheapest option, but has the highest resistance. An extension with HT pipes is ideal, as the HT pipes are suitable for the high temperatures (approx. 90 °C) of the tumble dryer.

Warm air can absorb and remove a large amount of water, so the warm air should cool down as late as possible. This can be achieved by good insulation. The exhaust air duct that runs through the cold attic should be insulated with at least 10 cm of mineral wool.

From an aerodynamic point of view, a reduction is not recommended. Ideally, the exhaust air duct should always have the same diameter.

The diameter depends on the exhaust air performance of the exhaust air hood. Up to 250 m³/h, the flat duct system 100 or round duct system Ø 100 is sufficient. For exhaust air capacities up to approx. 600 m³/h, the customer can choose between the flat duct system 125 or the round duct system Ø 125. For an exhaust air flow rate of up to 1000 m³/h, the flat duct system 150 or the round duct system Ø 150 must be selected.

The flat ducts can be glued with PVC adhesive, but this is not necessary. We recommend taping the connections with the 50 mm wide adhesive tape, as the trunking system can then be dismantled for cleaning purposes.

We do not recommend laying the flat trunking in concrete. The flat trunking is intended for installation on the wall. You can install our Ø 100, 125 and 150 round duct systems in concrete. To prevent the transmission of structure-borne noise, you should cover the pipes with an insulating hose.

The maximum conveying temperature for fans is 40-45°C depending on the model, flat ducts and ventilation grilles made of PVC plastic are dimensionally stable up to 60°C.

With drip irrigation, water and nutrients are transported drop by drop directly to the roots of the plant. This makes it easy to control the water supply and use the water very efficiently. SMART & GREEN drip irrigation is the quickest and easiest way to irrigate shrub beds, narrow strips or areas adjacent to buildings, walls, sidewalks and roads. The hose is laid on the ground, secured at regular intervals with ground spikes and optionally covered with soil or mulch.

Drip irrigation uses between 30% and 70% less water than an above-ground irrigation solution, with plants growing up to 50% faster. Water loss through evaporation and wind is efficiently prevented. The slow and regular application of water directly to the roots means that the plant grows faster, healthier and less stressed. In addition, the soil remains looser and is better aerated, which also promotes plant growth. SMART & GREEN drip irrigation products are easy to install. They are also very suitable for areas where water sprinklers cannot be used, e.g. on house walls. With drip irrigation, you can adapt the irrigation to any bed shape. By watering directly at the root, unsightly white, brown and even burnt spots on flowers and leaves can be avoided. It can also prevent the spread of fungi.

Drip irrigation is suitable for all shrub, flower and vegetable beds as well as hedges. You will be surprised with fuller flowering and greater beauty if you water your plants and fruit and vegetable beds with drip irrigation.

Accidental damage is easy to spot as a puddle will form above ground. To repair the hose, simply cut off the damaged area and attach a new piece of hose with matching components. Available from the manufacturer Netafim. The only tool required is a knife. The Marley SMART & GREEN Hunter® Irrigation Computer HC detects irregularities in water consumption and reports them to you. This gives you double security that water is not being used unnecessarily due to a leak.

The Netafim UniTechline pipe is used in the 50m hedge and bedding set. There is a physical root barrier in each dripper. This prevents roots from penetrating the pipe.

You should take precautions to ensure that your irrigation system is not damaged by frost. Dismantle the pressure reducer unit before the first frost and store it in a dry place over the winter. Open all hose ends and allow the residual water to run out of the hoses. Alternatively, you can use a compressor to blow the irrigation system dry so that no water remains in the hose and can freeze. Make sure that the pressure does not exceed 4 bar so that the components are not damaged.

The SMART & GREEN allotment kit can also be watered using a rain barrel, for example. The barrel must be placed at a height of 1.5 m to ensure sufficient pressure. Bear in mind that in warm summers the water from the barrel may not be sufficient and additional water is required. The SMART & GREEN drip irrigation sets can also be connected to rainwater tanks with a garden irrigation system or well pumps.

Do you already have an irrigation system in your garden and would like to integrate drip irrigation? Then you will need an additional irrigation line for drip irrigation. This can be easily connected to a cold water pipe using couplings. For automatic irrigation, you need an additional solenoid valve to which you connect the drip irrigation line. This means that it can also be controlled automatically via the computer.

We recommend a pipe diameter of 32mm for the installation of an irrigation system with sprinklers. A diameter of 25mm is sufficient for the drip irrigation line. The drip irrigation pipe with the pressure reducer unit is connected to the cold water pipe via a fitting.

Even if it may seem like it at first glance, SMART & GREEN drip irrigation is not just a garden hose with holes. The drippers are pressure-compensated and ensure even water delivery at each dripper over the entire length of the pipe. This means that the last plant gets just as much water as the first. The drippers in the hedge and bedding set also have a vacuum protection mechanism that prevents dirt particles from being sucked in. The pipes are permanently self-cleaning and resistant to blockages. They can therefore also be laid underground.

No, unfortunately this is not possible. The pipe from the hedge and bed kit can be laid underground. The other pipes should be laid above ground, but can be hidden very well under bark mulch or similar.

No, a complete irrigation system with computer and cold water pipe is not necessary. The drip pipes can also be connected to a garden hose if required. This solution also has the advantages of low water consumption and gentle watering of your plants.

No, the drip pipe is so flexible that it can be laid in larger bends around the plants. All the components required to lay the drip tube are included in the kits. You only need the additional items required to connect to your water source.

The duration of watering depends on the plants and the temperatures. It is therefore not possible to give a general answer. Overview of water delivery in liters/hour: Balcony and pot plant kit: 2 l/h (pressure-compensated) Vegetable and flower bed kit: 2 l/h at 1 bar Hedge and flower bed kit: 1.6 l/h (pressure-compensated) Small garden irrigation kit: 2 l/h at 1 bar With this information you can roughly calculate how long the watering should last. Observe the plants as they develop and adjust the watering duration accordingly. The duration should also depend on the current weather conditions.

The installation depends on the conditions in your garden. As a rule, the drip pipe is laid in straight rows directly alongside the plants. For larger plants, two pipes can also be laid in parallel so that each plant receives water from two sides. The pipes can also be bent and laid in a U-shape around the plants. Make sure that small plants have fewer drippers nearby than larger plants so that the latter receive more water. In our Marley garden, we have laid the drip pipe in loops around the plants as they are not in a row.
