Page 20: Operation
OPERATION Sequence of Operation Power-up When power is applied to the unit (230 VAC), L1 and L2 provide power to energize all relays, contactors, and control boards receive power. 1 leg of the compressor is energized. Power is supplied to the transformer which provides 24 VAC to the thermostat and the defrost control board. - Page 21 OPERATION Sequence of Operation Compressor Delay Time A change of reversing valve state will shut off the compressor at the start of a defrost cycle for the first 30 seconds of defrost operation. At the end of the defrost cycle, the compressor will be shut off prior to changing the reversing valve state. Following a 30 second delay, the compressor will be turned back on.
- Page 22 OPERATION Sequence of Operation Defrost Mode Operation When the unit goes into heat pump mode for the first time and the outdoor coil temp drops below 30 ˚F it will run a defrost to calibrate the control even though there is no ice build up. Normally the unit will go into defrost when the outdoor coil temp sensor provides signal to the board reads below 30 ˚F and the defrost control board detects a frost condition based on the the calibration point and the ambient temp sensor.
- Page 23 All Vert-I-Paks, by default, will be configured to low speed blower operation. The speed setting can be changed to high speed by updating the speed tap settings on the fan control relay. Any non-Friedrich thermostat or low voltage device being powered by the Vert-I-Pak will need to be reviewed and approved for use.

OPERATION General Knowledge Sequence Of Refrigeration A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difficult and time consuming, if not (in some cases) entirely impossible. The refrigeration system uses four basic principles in its operation which are as follows: “Heat always flows from a warmer body to a cooler body.”... -
