12. Maintenance instructions
Check and clean at regular intervals.
Cleaning the heat exchanger (possible without replacing the PHE):
- Vacuum, taking care not to bend the fins
- Clean with water (non-pressurised) or a soapy solution
Removal of the plate elements is possible using an appropriate retaining rail set.
- Cleaning methods that use high pressure (e.g. steam jet / high pressure
washer) carry a risk of irreparable mechanical damage to the plate heat
exchanger.
- Before restarting, replace the factory-fitted seal on the condensate pan if
this was removed during maintenance on the plate heat exchanger.

Electrical equipment
- Regularly check the electrical equipment of the unit.
- Replace loose connections and faulty cables immediately.
- Regularly check the earth conductor.
Servomotors on the dampers
The motors are maintenance-free.
At regular intervals, check that the connection from the servomotor to the
damper drive is firmly seated.
Trap
Regularly check the DN 50 trap (accessories) for possible soiling and clean if
required. (See checklist).
Refill the trap with water before returning into use.
