ALL AIR BEEN VENTED FROM THE COOLER LOOP?

CHILLED WATER (FLUID) PUMP (CWP) OPERATING WITH THE CORRECT ROTATION?

CWP MOTOR AMPERAGE:	Rated		Actual
PUMP PRESSURE:	Inlet		Outlet

C.Unit Start-Up(insert check mark as each item is completed)

CHILLER HAS BEEN PROPERLY INTERLOCKED WITH THE AUXILIARY CONTACTS OF THE CHILLED FLUID PUMP STARTER.

UNIT IS SUPPLIED WITH CORRECT CONTROL VOLTAGE POWER

(115 V FOR 208/230, 460, AND 575 V UNITS; 230 V FOR 380 AND 380/415 UNITS)

CRANKCASE HEATERS HAVE BEEN ENERGIZED FOR A MINIMUM OF 24 HOURS PRIOR TO START-UP.

COMPRESSOR OIL LEVEL IS CORRECT.

BOTH LIQUID LINE SERVICE VALVES ARE BACKSEATED.

ALL COMPRESSOR DISCHARGE SERVICE VALVES ARE BACKSEATED.

ALL COMPRESSOR SUCTION SERVICE VALVES ARE BACKSEATED.

LOOSEN COMPRESSOR SHIPPING HOLDDOWN BOLTS.

LEAK CHECK THOROUGHLY: CHECK ALL COMPRESSORS, CONDENSER MANIFOLDS AND HEADERS, EXVs, TXVs, SOLENOID VALVES, FILTER DRIERS, FUSIBLE PLUGS, THERMISTORS, AND COOLER HEADS, WITH ELECTRONIC LEAK DETECTOR.

LOCATE, REPAIR, AND REPORT ANY REFRIGERANT LEAKS.
