| Maintenance of the unit
Even if the required maintenance is carried out, dust will build up in the ex-
changer block. It is therefore of vital importance for the upkeep of a high effi-
ciency that the exchanger block is removed from the unit and cleaned
periodically as illustrated below. Clean the heat exchanger at least every 3
years or when required.
1. Disconnect the rotor power supply and the rotor sensor. The cables are
found beside the rotor at the back.
2. Pull out the rotor towards you. Some force may be needed.
3. Clean the rotor.
Wash in hot soapy water. Do not use detergent containing ammonia. Rinse
using, for instance, a shower handle.
Warning
Ensure the rotor motor is not exposed to moisture
4. Remount the rotor. Don't forget to reconnect the rotor power and sensor
cables.

Cleaning the fans

Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
The motor bearings are life time lubricated and mainte-
nance free.
Even if the required maintenance, such as changing of fil-
ters is carried out, dust and grease may slowly build up in-
side the fans. This will reduce the efficiency.
The fans may be cleaned as illustrated in below
procedure.
1. Disconnect the fan power cables. The cables are found
beside the fan at the back.
2. Pull out the fans towards you. Some force may be
needed.
3. Clean the fans with a cloth or a soft brush. Do not use
water. White spirit can be used to remove obstinate
deposits.
Allow the fans to dry properly before remounting.
4. Remount the fans. Don't forget to reconnect the fan
power cables.
