Maintenance
[ ] Clean and repaint any corroded surfaces.
[ ] Clean condenser coils. (Refer to "Coil Cleaning").
[ ] Inspect the expansion valve sensing bulbs for cleanliness; clean if
required. These sensing bulbs must make good contact with the suction
lines, and must be properly insulated.
[ ] Determine whether or not lubrication of the outdoor fan motor bearings is
needed; lubricate bearings with a light-weight oil (e.g., SAE-20 non-deter-
gent or equivalent), if necessary.
Note: CGA outdoor fan motor assemblies are permanently lubricated and
usually do not require additional oiling unless the unit is installed in a "dirty"
environment. Under such conditions, lubricate the fan motor bearings after
every 10,000 hours of operation. Do not over lubricate!
[ ] Clean condenser fans.

WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures recommended in
this section of the manual could result in exposure to electrical,
mechanical or other potential safety hazards. Always refer to the safety
warnings provided throughout this manual concerning these
procedures. When possible, disconnect all electrical power including
remote disconnects before servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently energized.
When necessary to work with live electrical components, have a
qualified licensed electrician or other individual who has been trained
in handling live electrical components perform these tasks. Failure to
follow all of the recommended safety warnings provided, could result
in death or serious injury.
Refer to unit schematics to check the number of disconnects required to de-
energize the unit.
Coil Cleaning
Clean the condenser refrigerant coil at least once each year (or more fre-
quently if the unit is located in a "dirty" environment) to help maintain proper
unit operating efficiency. Specific instructions for cleaning refrigerant coils
are outlined below. Follow these instructions as closely as possible to avoid
potential damage to the coils.
