System Start-Up
Compressor Start-Up
1. Ensure that the main power disconnect switch and the control power cir-
cuit breaker for the “System Solution Pump” is “On”.
2. Before closing the main power disconnect switch for the unit, ensure that
the compressor discharge service valve and the liquid line service valve
for each circuit is back seated.
CAUTION
Compressor Damage!
Compressor service valves must be fully opened before start-up
(suction, discharge, liquid line, and oil line). Failure to fully open valves
prior to start-up may cause compressor failure due to lack of refrigerant
and/or oil flow.
3. Remove the protective plastic coverings that shipped over the compres-
sors.
4. Check the compressor oil levels. The oil level in each manifolded set of
compressor sight glasses should be equally 1/2 to 3/4 full when they are
“Off”.
5. Check the condenser coils. They should be clean and the fins should be
straight. Straighten any bent coil fins with an appropriate sized fin comb.
6. Turn the main power disconnect switch or circuit protector switch that
provides the supply power to the unit’s terminal block 1TB1 or the unit
mounted disconnect switch 1S14 to the “On” position.
7. Turn the 24 volt control circuit switch 1S70 to the “On” position.
8. Open the Human Interface access door, located in the unit control panel,
and press the SERVICE MODE key to display the first service screen.
Refer to the latest edition of the CGAF-PTG for the SERVICE TEST
screens and programming instructions.
