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.
