8.3.2 Fan motor unit
• Motor and bearing are maintenance-free.
>> If necessary, clean the impeller with a soapy solution.
>> Check that the test lead is seated firmly at the test connector on the inlet nozzle
(errors may be encountered if the test lead is loose).
8.3.3 Electrical equipment
>> Check the unit's electrical equipment regularly.
>> Replace loose connections and faulty cables immediately.
>> Check the earth conductors on a regular basis.
8.3.4 Countercurrent plate heat exchanger (PHE)
>> 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.
• Cleaning methods that use high pressure (e.g. steam jet/high pressure washer) carry a risk of mechanically
destroying the plate heat exchanger
8.3.5 Electric preheating coil/electric reheating coil (accessory)
>> Check and clean at regular intervals.
>> Cleaning the electric coils:
• Vacuum, taking care not to bend the heating coils
• Blow off with compressed air, max. 1 bar.
• If the cleaning pressure is too high, there is a risk of irreparable mechanical damage to the electric coils.
• The electric heating coil must be protected from moisture and water.
8.3.6 Bypass damper/extract air damper/outdoor air damper/boost damper
>> Check the dampers for ease of movement.
>> Never lubricate the dampers. This could destroy the plastic used and compromise the damper function.
>> To clean, wipe down with a soapy solution; otherwise maintenance-free.
8.3.7 Damper servomotors OPEN/CLOSED or variable
• The motors are maintenance-free.
>> At regular intervals, check that the connection from the servomotor to the damper drive is firmly seated.
8.3.8 Condensate pans
>> Regularly check the condensate pans for contamination and clean if required.
8.3.9 Trap
>> Regularly check the trap for contamination and clean if required.
>> Refill the trap with water before returning into use.
