SECURE OWNER'S APPROVAL:

When the system is functioning properly, secure the owner's approval. Show him the

location of all disconnect switches and the thermostat. Teach him how to start and stop the unit, how to adjust temperature
settings within the limitations of the system, how the defrost cycle is controlled and how the anti-cycle timer operates.

INDOOR COIL

Do not allow dirt to accumulate on the indoor coil or other parts
of the supply/return air circuit. Clean as often as necessary to
assure good system performance. Use a brush, vacuum
cleaner attachment or other suitable means.

If the coil becomes extremely dirty, it may be necessary to use
an industrial grade detergent and a hose to clean the finned sur-
faces. This is recommended to prevent any loss in capacity and
efficiency.

DRAIN PAN

The condensate drain pan should be inspected regularly to as-
sure proper drainage.

FILTERS

The filters must be replaced as often as necessary to assure
good air flow and filtering action. Clean filters will prevent any
loss in capacity and efficiency.

Refer to the unit drawing in Fig. 12 for the location of the filter
access panel.

LUBRICATION

The bearings for the blower shaft and the blower motor are per-
manently lubricated and should not require any additional lubri-
cant.

BELTS

Maintain belt tension to extend belt life. Replace when signs of
failure begin to appear.
