INDICATIONS OF PROPER OPERATION

Cooling

1.

The outdoor fan should be running, with warm air being dis-
charged from the top of the unit.

2.

The indoor blower (furnace or air handler) will be operating, dis-
charging cool air from the ducts. Coils or other parts in the air cir-
cuit should be cleaned as often as necessary to keep the unit
clean. Use a brush, vacuum cleaner attachment, or other suitable
means.

3.

The vapor line at the outdoor unit will feel cool to the touch.

4.

The liquid line at the outdoor unit will feel warm to the touch.

Instructing the Owner

Assist owner with processing warranty cards. Review Owners Guide
and provide a copy to the owner and guidance on proper operation and
maintenance. Instruct the owner or the operator how to start, stop and
adjust temperature setting.

When applicable, instruct the owner that the compressor is equipped
with a crankcase heater to prevent the migration of refrigerant to the
compressor during the “OFF” cycle. The heater is energized only when
the unit is not running. If the main switch is disconnected for long peri-
ods, do not attempt to start the unit until 8 hours after the switch has
been connected. This will allow sufficient time for all liquid refrigerant to
be driven out of the compressor.

The installer should also instruct the owner on proper operation and
maintenance of all other system components.

Maintenance

1.

Dirt should not be allowed to accumulate on the outdoor coils or
other parts in the air circuit. Clean as often as necessary to keep
the unit clean. Use a brush, vacuum cleaner attachment, or other
suitable means.

2.

The outdoor fan motor is permanently lubricated and does not
require periodic oiling.

3.

If the coil needs to be cleaned, it should be washed with Calgon
Coilclean (mix one part Coilclean to seven parts water). Allow
solution to remain on coil for 30 minutes before rinsing with clean
water. Solution should not be permitted to come in contact with
painted surfaces.

4.

Refer to the furnace or air handler instructions for filter and blower
motor maintenance.

5.

The indoor coil drain pan should be inspected and cleaned regu-
larly to prevent odors and assure proper drainage.
