SERVICING

NOTE: The compressor may run backwards (noisy opera- tion) for 1 or 2 seconds at shutdown. This is normal and does not harm the compressor.

1.Install gauges and verify that the suction pressure drops while the discharge pressure increases.

2.Listen for normal compressor sound levels. Reverse rota- tion results in elevated or unusual sound levels.

3.Reverse rotation will result in substantially reduced amp draw from tabulated values.

To correct improper rotation, switch any two power supply leads at the outdoor unit contactor.

The 3 phase Scroll Compressors are direction of rotation sen- sitive. They will rotate in either direction depending on the phasing of the power. There is no negative impact on durabil- ity caused by operating 3 phase compressors in reversed rotation. The compressors internal protector will trip, de-en- ergizing the compressor. Continued operation of 3 phase scroll compressors with the rotation reversed will contribute to com- pressor failure. All 3 phase scroll compressors should be checked for correct phase rotation.

S-105B THERMOSTATIC EXPANSION VALVE

The expansion valve is designed to control the rate of liquid refrigerant flow into an evaporator coil in exact proportion to the rate of evaporation of the refrigerant in the coil. The amount of refrigerant entering the coil is regulated since the valve responds to temperature of the refrigerant gas leaving the coil (feeler bulb contact) and the pressure of the refrigerant in the coil. This regulation of the flow prevents the return of liquid refrigerant to the compressor.

The illustration below shows typical heat pump TXV/check valve operation in the heating and cooling modes.
