Evaporator and Condenser Coil Cleaning

Periodically the coils should be cleaned. No fixed period for cleaning can be provided due to the varying
environments in which the air conditioner may be installed. However once the coils become visibly coated
with dust it is recommended that they be cleaned with a brush or compressed air. Both sides of the coils
should be inspected regularly.
6.3 Compressor & Refrigerant System
The compressor is a hermetically sealed and factory lubricated unit and therefore requires no maintenance. If
the compressor fails it is recommended that the unit be returned to Dantherm Inc. for servicing. In the event
that the unit cannot be returned it is possible, using suitably qualified personnel, to repair the unit in the field.
If the refrigerant charge is lost the means of leakage should be established and repaired by a reputable
refrigeration repair company. Ports are provided for checking suction and discharge pressures and recharging
if required. The type of refrigerant and charge amount is detailed on the product label attached to the unit.
Note: Under no circumstance must the access port covers be removed, adjusted, or tampered with
other than by a certified technician.
