Troubleshooting

WARNING

Hazardous Service

Procedures!

The maintenance and trouble shooting procedures recommend- ed in this section of the manual could result in exposure to electri- cal, mechanical or other potential safety hazards. Always refer to the safety warnings provided throughout this manual concern- ing these procedures. When possi- ble, disconnect all electrical power including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be in- advertently energized. When nec- essary to work with live electrical components, have a qualified li- censed electrician or other indi- vidual who has been trained in handling live electrical compo- nents per these tasks. Failure to follow all of the recommended safety warnings provided, could result in death or serious injury.

Preliminary Trouble Inspection If operational difficulties are encoun- tered, be sure to perform the prelimi- nary checks before referring to the troubleshooting chart on page 28.

•Verify that the unit is receiving elec- tric supply power.

•Ensure that the fuses in the fused disconnect are intact.

After completing the preliminary checks, inspect the unit for other obvi- ous problems such as leaking connec- tion, broken or disconnected wires, etc. If everything appears to be in or- der, but the unit still fails to operate properly, refer to the troubleshooting chart on page 28.

General Operation

The standard model is designed for in- door installation. When the unit is in- stalled in an unconditioned space, the unit may not start in cool weather (ap- proximately 45°F). It may then be nec- essary to start the unit in the cooling mode for three to five minutes. The unit may then be shut-off (there will be a two minute time-out of the unit), and restarted in the heating mode. The freeze protection thermostat should also be checked as it may be adversely affected by ambient temperature. Like any other type of mechanical equipment, the unit performs best when it is well maintained.

Operation with a Conventional Thermostat

The unit is equipped with safety con- trols, including high pressure control, low pressure control and a freeze pro- tection thermostat, set to shut off the compressor under abnormal tempera- ture or pressure conditions. If the safe- ties shut off the compressor, a lockout relay prevents short cycling from the abnormal condition. When conditions are corrected, the lockout control can be reset by setting the thermostat sys- tem switch to OFF wait a few minutes for the system pressure to equalize, and then return to HEAT or COOL. If the condition continues, an authorized service person should check out the unit.
