CHECKING THE SYSTEM
PRIOR TO INITIAL START (NO POWER)
Unit Checks
1. Inspect the unit for shipping or installation dam-
age.
2. Ensure that all piping has been completed.
3. Visually check for refrigerant piping leaks.
4. Open suction line ball valve, discharge line ball
valve, and liquid line valve for each system.
5. The compressor oil level should be maintained so
that an oil level is visible in the sight glass. The
oil level can only be tested when the compressor
is running in stabilized conditions, guaranteeing
that there is no liquid refrigerant in the lower shell
of the compressor. In this case, the oil should be
between 1/4 and 1/2 in the sight glass. At shut-
down, the oil level can fall to the bottom limit of
the oil sight glass.
6. Ensure water pumps are on. Check and adjust
water pump flow rate and pressure drop across
the cooler
.
Verify flow switch operation.
Excessive flow may cause catastrophic
damage to the evaporator.
EQUIPMENT STARTUP CHECKLIST
7
. Check the control panel to ensure it is free of
foreign material (wires, metal chips, or similar
material).
8. Visually inspect wiring (power and control). Wir-
ing MUST meet NEC and local codes.
9. Check tightness of power wiring inside the power
panel on both sides of the motor contactors and
overloads.
10. Check for proper size fuses in main and control
circuits, and verify overload setting corresponds
with RLA and FLA values. Refer to
Electrical
Tables in the IOM (150.66-NM2)
or unit name-
plate.
11. Ensure 120 VAC Control Power to TB1 has 15 A
minimum capacity.
12. Be certain all water temp sensors are inserted
completely in their respective wells and are coated
with heat conductive compound.
13. Ensure that evaporator TXV bulbs are strapped
onto the suction lines at 4 or 8 o’clock positions
or suction temp. sensors if EEVs are installed.
COMPRESSOR HEATERS
(POWER ON – 24 HOURS BEFORE START)
1. Apply 120 VAC and verify its value between
terminals 5 and 2 of TB1. The voltage should be
120 VAC ± 10%.
Power must be applied 24 hours before start-up.
Each heater should draw approximately 0.5 A to
1A.
PANEL CHECKS
(POWER ON – BOTH UNIT SWITCHES OFF)
1. Apply three-phase power and verify its value.
Voltage imbalance should be no more than 2% of
the average voltage.
2. Apply 120 VAC and verify its value on the ter-
minal block in the Power Panel. Make the mea-
surement between terminals 5 and 2 of TB1. The
voltage should be 120 VAC +/- 10%.
3. Program/verify the Cooling Setpoints, Program
Setpoints, and unit Options. Record the values in
Table 1.
