Monthly Maintenance and Inspection
Checks
Air Filters
CAUTION
Do NOT operate unit without air filters.
Inspect filters at least monthly and replace or clean as re-
quired. Washable filters may be cleaned by soaking in mild
detergent and rinsing with cold water. Replace filters with
the arrows on the side pointing in the direction of air flow.
Dirty filters are the most common cause of inadequate
heating or cooling performance, and of compressor fail-
ures.
Refrigeration Access Ports
This unit is equipped with refrigeration access ports
mounted on the side of the unit. Refer to FIGURE 9 for
identification of ports.

Cooling Season Checks (Monthly)
Condenser Coil
Keep the condenser inlet and outlet area clean and free of
leaves, grass clippings or other debris. Grass should be
kept short in front of the condenser inlet. Shrubbery MUST
be trimmed back so it is no closer than 30 inches (762mm)
to unit.
Condensate Drain
Check for condensate drainage. Clean as required.
Annual Maintenance and Inspection
Electrical shock hazard.
Turn OFF electric power supply at disconnect
switch or service panel before removing any ac-
cess or service panel from unit.
Failure to follow this warning can result in prop-
erty damage, personal injury, and/or death.
The annual inspection MUST include lubrication and
cleaning as required to ensure efficient operation of the
unit. To simplify access, remove all access panels and the
top from the unit if possible.
Condenser Fan Motor
CAUTION
Do not use 3 in 1 oil, penetrating oil, WD40 or similar
oils to oil motor bearings.
Oil the condenser fan motor after five years of operation
and every five years thereafter.
Use SAE 10W30 motor oil. To oil, remove the hole plugs
from the motor end bells and add several drops (approxi-
mately 1/2 teaspoonful) of oil with a squeeze type, flexible
tube oiler. Replace hole plugs after oiling. Do NOT over oil.
Clean the surrounding area and the condenser and evapo-
rator coils. Use caution to avoid damage to coil fins.
