Maintenance overview

Always ensure that before maintenance work begins, the device is isolated from the mains supply by removing the power cord from the wall socket or by switching off the fuse Check by measurement that this is actually the case.

Window ventilators

Window ventilators require little maintenance, but to enjoy year-round use of your window ventilators, optimum operation and healthy indoor air quality, we would advise the following.

• Window ventilators can be cleaned very quickly and easily for optimum ventilation.
• Failure to carry out these maintenance operations may result in the control malfunctioning or failing to operate at all.
• You are strongly advised against the use of abrasives (e.g. sandpaper or scouring pads), pressure washers and harsh cleaners (e.g. solvents or ammonia).
• You will find a number of maintenance videos on the DUCO website (www.duco.eu).

B.1 Maintenance frequency

• Check the window ventilators regularly (approximately once every 2 months) for fouling. You will need to clean the window ventilators in case of fouling.
  » Cleaning twice a year is sufficient in rural surroundings.
  » If you live in an urban environment, next to an industrial area or on the coast, you will need to clean your window ventilators 6 times a year.

• Hinged or rotating parts need to be lubricated annually. Use a dry lubricant for this (Teflon spray).

• Window ventilators with fabric solar shading: As the manufacturer, we recommend regular technical check-ups on your system by the installer
  » Annually for non-residential buildings
  » Every 4 years for domestic solar shading

• For electronically controlled window ventilators: Regularly inspect the wiring for damage. Changes to the electrical part may only be carried out following the manufacturer’s approval.

B.2 How to clean
Window ventilators with a removable insect-repellent inside grille

• Set the ventilation flap to the fully open position using the control (lever or crank).
• Take the removable insect-repellent inside grille off by hand.
• Clean the removable inside grille with a vacuum cleaner and then with a damp cloth (soap and water (e.g. a general-purpose cleaner)).
• Fouling on the inside, including the ventilator flap or the rotary barrel mechanism, of the window ventilator is best removed by sucking out or cleaning using a vacuum cleaner, brush or duster/damp cloth. Carefully check also for fouling that may have accumulated in the corners. If so, remove it as well.

• Fabric blind
  » If the fabric becomes wet due to an unexpected shower, you may simply roll up the blind, and then unroll it again in better weather to allow it to dry. However, make sure not to keep the blind rolled up wet for more than 3 days to prevent moulding and stains.
  » Remove loose fouling first using a brush or vacuum cleaner before wiping.
  » You can then remove the remaining dirt after using a cleaning agent and lukewarm water (special cleaning products are available from the installer).
  » Always rinse off the fabric after cleaning.
  » Avoid cleaning in bright sunlight: if soapy water dries quickly, it can leave stains on the fabric. Do not use any aggressive scouring agents.

• Lateral guides
  (= maintenance of frame and arms)
  » It is recommended that you should have the hinge pins, wheel shafts and bearings on your solar shading checked once a year.
  » DUCO recommends to clean your articulated arms (for the CAP version) using a damp sponge (soap and warm water (e.g. a general-purpose cleaner)).
  » Lubricate the pivoting or rotating components after cleaning your solar shading.
  » A dry lubricant (Teflon spray) can be applied to plastic guide blocks and aluminum guide sections after cleaning.
  » A dry lubricant (Teflon spray) needs to be applied to diagonal or horizontal sections in which guide blocks slide.
  » Plastic sliding bearings can be lubricated using a dry lubricant (Teflon spray) after cleaning (remove twigs and leaves).

Exhaust vents

Air is extracted from kitchens, bathrooms and toilets through exhaust vents. These are usually vents incorporated in the ceiling.
Take care not to change the setting and position of the valve control mechanism. Make sure that the vents are not interchanged, i.e. that they are put back in their original ventilation opening in the wall or ceiling. All this may affect the flow rate and the proper functioning of the ventilation system.
C.1 Maintenance frequency

• As a resident, you need to carry out the inspection and cleaning yourself.
• Check the vents regularly (approximately once every 2 months) for fouling.
• Clean the vent with a damp cloth as soon as you notice any fouling.

C.2 How to clean
DucoVent Design

• Remove the aluminum finishing plate, which is attached with magnets, from the actual vent.
• The finishing plate can now be cleaned with a damp cloth (soap and water (e.g. a general-purpose cleaner)). Never immerse the aluminum finishing plate in water, so as to protect the magnets.
• Take the acoustic foam pack out of the vent. The foam can be cleaned using a vacuum cleaner. The plastic part with a damp cloth.
• The inside of the duct can be cleaned with a vacuum cleaner.
• Place the acoustic foam pack back in the vent. Make sure that the foam is inserted up to the top of the ceiling section.
• Place the finishing plate back on the vent. It is attracted by the 4 magnets and positions itself.

DucoVent Basic

• For light fouling, wipe the exhaust vents or window ventilators with a slightly damp cloth.
• If necessary, use a solution of a mild cleaner (washing-up liquid/general-purpose cleaner).
• If there are heavy deposits of fouling, take the exhaust vents out of the duct completely.
  1. Take hold of the outer edge of the vent and pull it completely out of the wall or ceiling in a twisting movement.
  2. Remove the foam rubber sealing strip.
  3. Immerse the exhaust vents completely in a solution of general-purpose cleaner.
  Exhaust vents can be cleaned in the dishwasher if necessary.
  4. Wipe the exhaust vents off with a cloth or soft brush.
  5. Dry the exhaust vents. Place the foam rubber sealing strip back onto the exhaust vent.
  6. Place each exhaust vent back into its original duct.

Central extract unit

D.1 Maintenance frequency

• Before (possibly) proceeding to clean your extract unit, as a resident, you need to inspect it to establish whether it is necessary.
• Your central extract unit needs to be cleaned by an accredited installer.
• In a newbuild home, the DucoBox needs to be cleaned completely, i.e. including Box Sensors and Control Valves (if present), after 6 months.
• After these 6 months, you will need to repeat this operation every 3 – 4 years, depending on the degree of fouling.
• If the central extract unit is used in combination with a cooker hood, then maintenance will be required more frequently than indicated above. This will require additional maintenance, such as cleaning / replacing filters, the motor and the Box Sensors plus Control Valves, if present.
• Technical maintenance of the DucoBox is not necessary.

D.2 How to carry out check-ups

1. Isolate the DucoBox.

2. Open the cover.

Heat Recovery Ventilation System

E.1 Maintenance frequency

1. Cleaning must be done by an accredited installer.
2. In order to guarantee proper and safe operation, the DucoBox WTW must be (visually) checked and inspected at least every 12 months by an accredited installer or service organisation.
3. The maintenance of the DucoBox WTW is limited to checking the fan once a year and for leaks on water-side parts.
4. The filter of the DucoBox WTW must be checked and/or replaced annually to ensure proper operation of the heat recovery ventilation system. If the filter is not replaced every year, the dust particles will accumulate, which may cause malfunctions.
5. Technical maintenance of the DucoBox WTW is not necessary.
6. When the DucoBox WTW is used in combination with a cooker hood where this cooker hood without motor is fitted to one of the connections in the kitchen, the maintenance frequency will be higher than indicated above. This will require additional maintenance, such as cleaning /replacing filters and the motor. The maintenance frequency of the filter may then have to be adjusted, due to a greater degree of fouling. If a cooker hood is connected to the ventilation system, thefilter needs to be replaced every 4 months. DUCO recommends installing a cooker hood with a motor and its own connection to the outside.

E.2 How to replace filters

1. The filter must be replaced by the resident.

2. Filters cannot be cleaned.
   » Manual cleaning with a vacuum cleaner can damage the fine structure of the filter. This also applies to washing out the filters.

3. Replacing the filter
   a. Open door
   b. Replace filter
   c. Close door

E.3 How to clean the casing

1. Cleaning of the casing must be carried out by the resident.
2. Clean the casing of the heat recovery ventilation system only with a damp cloth (water and soap (e.g. an all-purpose cleaner)).
3. You are strongly advised against the use of abrasives (e.g. sandpaper or scouring pads), pressure washers and harsh cleaners (e.g. solvents or ammonia), that can affect the paintwork or plastic parts.

E.4 How to carry out check-ups

1. Check-up must be done by an accredited installer.
2. Isolate the DucoBox WTW.
3. Open the door.
4. Loosen the screw completely, releasing the control panel.
5. Loosen the other 5 screws half way, so that the aluminum plate can be pushed upwards.
6. Check the proper functioning of the heat recovery ventilation system.
7. Carry out a visual check towards the water-side to see if there are any leaks.
8. Check that the water on the plate under the evaporator can drain properly to the siphon. Make sure the hole is free of dirt or other obstructions.
9. Check the fan and evaporator for fouling. A small amount of fouling has little effect on the extract unit’s and the evaporator’s performance. If the fouling is more than 1 mm thick , we advise you to have them cleaned.
10. Check the bearings. You can do this by turning the impeller by hand.
11. Check that the bearings do not make noise and that no resonance occurs.
12. Check that the fan is not swinging.
13. When the fan is set in motion by hand, it only makes a few revolutions and then comes to a standstill with some jerks. This is a characteristic of a DC extract unit and is therefore entirely normal.
14. Depending on theoutcome of the inspection, theextract unit will need to be cleaned and/orprepared for use.
15. Check that there are no air leaks.
16. Check the central heating water pressure and top up if necessary. See installation manual DucoBox WTW.

Ventilation ducts
F.1 Maintenance frequency
• Your ventilation ducts need to be cleaned by an accredited installer.
• The contamination of the existing ventilation ducts can sometimes take on serious forms. It is therefore necessary to clean the ducts on a regular basis, approximately once every 6 years. This can of course differ from situation to situation, depending on the extent of fouling.

Control components

G.1 Maintenance frequency

• Operating and control components require no maintenance during their service life. However, operation may be impaired by air slot fouling. Therefore, as a resident, regularly remove the dust from the casing with a dry duster or with a vacuum cleaner if necessary.
• DUCO recommends a 3-yearly maintenance of its ventilation system control components by an accredited installer.

H. Kitchen Box
As a resident, you need to carry out the inspection and cleaning yourself.
H.1 Maintenance frequency
Check the Kitchen Box (and valves) regularly (approximately once every 2 months) for fouling.
H.2 How to clean

• Remove the inspection hatch by hand.
• Clean the removable inspection hatch with a vacuum cleaner and then with a damp cloth (soap and water (e.g. a general-purpose cleaner)).
• Clean the Kitchen Box with a damp cloth as soon as you notice any fouling. Attention: the IAV valve is a 24 V fed item.
• Take care not to change the setting and position of the valve control mechanism and the throttle valve. If more than one valve has been mounted on the Kitchen Box , make sure that the valves are not interchanged and that they are therefore placed back in the original ventilation opening in the Kitchen Box. All this may affect the flow rate and the proper functioning of the ventilation system.
• Fouling on the inside, including on the throttle valve of the Kitchen Box, is best removed by sucking out or cleaning using a vacuum cleaner, brush or (damp) cloth. Carefully check also for fouling that may have accumulated in the corners. If so, remove it as well.
• The inside of the duct can be cleaned with a vacuum cleaner.
• Put the removable inspection hatch back onto the Kitchen Box.
