SCHEDULED MAINTENANCE
AFTER EVERY 10 HOURS OF OPERATION:
Clean the Condenser to maintain high efficiency performance of the RRC770. Disconnect
power and remove the Compressor Compartment Cover and blow compressed air through
the cooling fins of the Condenser to remove any debris. It may be necessary to use a soft
brush if the fins are excessively dirty.
Do not bend the fins on the Condenser coil. Air flow will be restricted and cause damage
to the RRC770. Replace the Compressor Compartment Cover before applying power to
the RRC770.
COMBO FILTER MAINTENANCE
Two Combo Filters are installed in the middle section of the RRC770.
The OUTLET Combo Filter can be identified by the presence of insulation around the
outside.
This Outlet Combo Filter must be changed after
50
hours operation. Hours are indicated
on the Hour Meter.
The INLET Combo Filter does not have insulation around the outside. This Inlet Combo
Filter must be changed
after 25
hours operation. Hours are indicated on the Hour Meter.
