Unit Start-Up Procedures
Stopped to Starting:
The stopped to starting diagram shows the timing from a stopped mode to energizing the
compressor. The shortest allowable time would be under the following conditions:
20. No motor restart inhibit
21. Evaporator Water flowing
22. Power up Start Delay Timer has expired
23. Adjustable Stop to Start Timer has expired
24. Need to cool
The above conditions would allow the compressor to start in 60 seconds.
CAUTION
Refrigerant!
If both suction and discharge pressures are low but sub-cooling is normal, a problem other than
refrigerant shortage exists. Do not add refrigerant, as this may result in overcharging the circuit.
Use only refrigerant specified on the unit nameplate (R-410A) and OIL00080 (1 gallon). Failure to
do so may cause compressor damage and improper unit operation.
CAUTION
Equipment Damage!
Ensure that the oil sump heaters have been operating for a minimum of 24 hours before
starting. Failure to do so may result in equipment damage.
