4.0 – SERVICE
4.1 – Cleaning
Inspect unit interior at beginning of each heating and cooling season and as operating conditions require. Remove
unit top panel and/or side panels for access to unit interior.
EVAPORATOR COIL — Clean as required with a commercial coil cleaner.
CONDENSER COIL — Clean condenser coil annually and as required by location and outdoor-air conditions.
Inspect coil monthly and clean as required.
CONDENSATE DRAIN — Check and clean each year at start of cooling season.
FILTERS — Clean or replace at start of each heating and cooling season, or more often if operating conditions
require. Refer to Table 1 “Physical Data” type and size.
4.2 – Lubrication
Compressors are charged with the correct amount of oil at the factory.
Replacing Compressor - In the case of a motor burnout, the majority of contaminated will be removed with the
compressor. The rest of the oil is cleaned through the use of suction and liquid line filter driers. A 100% activated
alumna suction line filter drier is recommended but must be removed after 72 hours.
The compressor contains POE oil. POE oil has a high affinity for moisture. Do not remove the compressor’s tube
plugs until ready to insert the unit suction and discharge tube ends. The discharge connection plug should be
removed first before pulling the suction connection plug to allow the dry air pressure inside the compressor to
escape.
Note: This is only valid for the R410A systems.
