Yes
No
3. All air has been purged from the system.
Yes
No
4. Chilled water pump starter controlled by chiller.
Yes
No
5. Chilled water flow switch operational.
Yes
No
6. Units installed in open loop: inlet piping to evaporator includes a 20 mesh strainer
within 10 ft of unit.
Yes
No
7. Water loop volume greater than 3 gal/ton (40 L/kW) for air conditioning
or 6 gal/ton (80 L/kW) for process cooling and low ambient operation.
Yes
No
8. Proper loop freeze protection provided to ____
F (
C).
Antifreeze type__________________ Concentration _____%.
Yes
No
(If antifreeze solution is not utilized on 30XV machines and the minimum
outdoor ambient is below 32 F (0
C), then items 10 and 11 have to be completed
to provide evaporator freeze protection to –20 F (–28.9 C). Refer to Installation
Instructions for proper evaporator winterization procedure.)

Yes
No
2. Verify actuated ball valve (ABV) operation.
Yes
No
3. All suction and discharge service valves are open.
Yes
No
4. Economizer service valves open. (Leaving Main EXV and
Leaving Brazed Plate Heat Exchanger [Economizer])
Yes
No
5. Oil service valves open.
Yes
No
6. Leak check unit. Locate, repair and report any refrigerant leaks.
Yes
No
7. Voltage at terminal block is within unit nameplate range.
Yes
No
Check voltage imbalance: A-B______ A-C______B-C______
Average voltage = __________ (A-B + A-C + B-C)/3
Maximum deviation from average voltage = _______
Voltage imbalance = ______% (max. deviation / average voltage) X 100
Is voltage imbalance less than 2%.
Yes
No
(DO NOT start chiller if voltage imbalance is greater than 2%.
Contact local utility for assistance.)
8. Verify evaporator flow rate
Pressure entering evaporator _____ psig (kPa)
Pressure leaving evaporator _____ psig (kPa)
Evaporator pressure drop _____ psig (kPa)
Psig x 2.31 ft/psi = _____ ft of water
kPa x 0.334 m/psi = _____ mm of water
Evaporator flow rate _____ gpm (L/s) (See Evaporator Pressure Drop Curve)
Start and Operate Machine
1. Complete component test utilizing Quick Test Mode
2. Operate all condenser fans and verify operation and rotation.
3. Operate compressors using manual test mode.
4. Check refrigerant and oil charge. Record charge information.
5. Record compressor and condenser fan motor current.
6. Record operating data.
7. Provide operating instructions to owner’s personnel.
