Chilled Water System Check
1. All chilled water valves are open. Ye s No
2. All piping is connected properly. Yes No
3. All air has been purged from the system. Ye s No
4. Chilled water pump starter controlled by chiller. Yes No
5. Chilled water flow switch operational. Ye s No
6. Units installed in open loop: inlet piping to evaporator includes a 20 mesh strainer
within 10 ft of unit. Ye s 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 _____%. Ye s 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.)
9. Outdoor piping wrapped with electric heater tape. Ye s No
10. Evaporator heaters and oil separator heaters installed and operational. Ye s No
11. Is the Unit equipped with low ambient head pressure control? Ye s No
a. If yes, are wind baffles installed? Ye s No
C. UNIT START-UP
1. All liquid line service valves are open. Ye s No
2. Verify actuated ball valve (ABV) operation. Ye s No
3. All suction and discharge service valves are open. Ye s No
4. Economizer service valves open. (Leaving Main EXV and
Leaving Brazed Plate Heat Exchanger [Economizer]) Yes No
5. Oil service valves open. Ye s No
6. Leak check unit. Locate, repair and report any refrigerant leaks. Ye s 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%. Ye s 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)
