Temporary belt repair solution
1. Stop the unit by disconnecting the mains.
Remove the cover of the unit.
Remove the heat exchanger cover.
2. Use tape to attach the drive belt to the rotating heat
exchanger, and rotate the exchanger by hand to get
hold of the drive belt.
3. Remove the tape and put the ”empty” end on to the
nipple. Press the ends firmly towards each other and
tighten the nipple.
4. Pull the drive belt on to the belt pulley and rotate the
exchanger by hand. Check that the belt pulley rotates.
Note:
If the drive belt slips, the drive belt may be
too long and needs to be shortened.
Shorten the drive belt by 5 mm and repeat
procedure.
5. If the belt pulley cannot be accessed, the heat ex-
changer package have to be removed in order to tem-
porary repair a broken drive belt.
6. Put back both covers and connect the unit to mains.
7. Check that the alarm has ceased on the Control Display.
Note:
If the alarm remains, check the rotor sensor.
4.7 Duct System Maintenance
4.7.1 Cleaning extract louvres and supply air diffusers
The system supplies fresh air to your home and extracts the used indoor air via the duct system and diffusers/louvres.
Diffusers and louvres are mounted in ceilings/walls in bedrooms, living room, wet rooms, WC etc. Remove diffusers
and louvres and wash in hot soapy water as required (diffusers/louvres must not be exchanged). Cleaning of diffusers/
louvres can be done as necessary.
4.7.2 Checking the outdoor air intake
Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille, and clean as
necessary. It is recommended to do this at least twice a year.
4.7.3 Checking the roof cowl (if fitted)
The roof cowl (if fitted) connected to the exhaust air duct needs to be checked at least twice a year and cleaned if
necessary.
4.7.4 Checking and cleaning the duct system
Dust and grease deposits may build up in the duct system, even if required maintenance such as changing of filters is
being carried out. This will reduce the efficiency of the installation.
