C. Cooler Loop Freeze Protection (if required)
Gallons (liters) added:________________
Piping includes electric tape heaters if piping is exposed to temperatures below freezing?
On brine units, has the cooler fluid been properly protected from freezing to at least 15 F
(8.3 C) below the lowest anticipated leaving fluid temperature set point?
Have the main base board, energy management module (option) and control relay
connections been checked for tightness?
(30MPA ONLY)
Has the refrigerant piping been done per the installation guide?
Piping dehydrated and evacuated per installation guide?
Unit charged per the installation guide?
(ALL 30MPA AND 30MPW050-071)

EQUIPMENT: Chiller:
COMPRESSORS:
MODEL NO.
SERIAL NO.
Chiller has been properly interlocked with the auxiliary contacts of the chilled fluid pump starter.
Chiller has been properly interlocked with the auxiliary contacts of the condenser water pump starter
(30MPW units only).
Compressor oil level is correct.
Liquid line service valve is back seated (30MPA units only).
Set point should be adjusted to the desired cooler leaving fluid temperature.
Leak check thoroughly: check all compressors, condenser manifolds and headers, TXVs, solenoid valves, filter
driers, fusible plugs, thermistors, and cooler connections using electronic leak detector. Locate, repair, and report
any refrigerant leaks.
Check voltage imbalance: AB_________ AC_________ BC_________
AB + AC + BC (divided by 3) = average voltage = ____________
Maximum deviation from average voltage =____________
