Periodic inspection
The operation parameters for the extract air heat pump must not be changed
unless a check is first made to ascertain that the changes will be within the
unit’s operating range.
Leakage inspection and registration
For information on the operator’s responsibility with regards to leakage inspec-
tion and registration, see "2.6 Handling of refrigerant" page 6. For access to
the cooling circuit and compressor, see "Access to the cooling circuit and com-
Inspection
Check:
1. The coil fins to detect possible mechanical deformity
2. the drip tray and drain (clean if necessary)
3. frost protection for outlet pipes
4. traces of oil residues, which may indicate leakage on the refrigerant circuit.
For service and repair of the refrigerant circuit call a certified refrigeration
technician.
Cleaning
If the fins on the coil are dirty, vacuum clean from the inlet side. Exercise care
when vacuuming, as the fins are thin and can be damaged through careless
contact. Alternatively, you can blow them clean with compressed air from the
outlet side. In the event of heavy soiling, you can clean them with warm water
mixed with dishwashing detergent that will not corrode aluminium.
For more information refer to heavy soiling under Documentation at
