COOLER LOOP PROTECTION IF REQUIRED:

GALLONS (LITERS) OF BRINE ADDED:

PIPING INCLUDES ELECTRIC TAPE HEATERS.

CHECK PRESSURE DROP ACROSS COOLER.

FLUID ENTERING COOLER:		PSIG (kPa)
FLUID LEAVING COOLER:		PSIG (kPa)

(PSIG DIFFERENCE) x 2.31 = FT OF FLUID PRESSURE DROP = (kPa DIFFERENCE) x .335 = FT OF FLUID PRESSURE DROP =

PLOT COOLER PRESSURE DROP ON PERFORMANCE DATA CHART (LOCATED IN PRODUCT DATA LITERATURE) TO DETERMINE TOTAL GPM (L/s).

TOTAL GPM (L/s) =					UNIT'S RATED MIN. GPM (L/s) =
GPM (L/s) PER TON =					UNIT'S RATED MIN. PRESSURE DROP =
JOB'S SPECIFIED GPM (L/s) (if available)					(Refer to product data literature.)
JOB'S SPECIFIED GPM (L/s) (if available)

NOTE: IF UNIT HAS LOW FLUID FLOW, FIND SOURCE OF PROBLEM: CHECK FLUID PIPING, IN-LINE FLUID STRAINER, SHUT-OFF VALVES, CHILLED FLUID PUMP ROTATION, ETC.

COOLER LOOP PROTECTION:

GAL. (L) OF BRINE ADDED (IF REQUIRED).

IN-LINE WATER STRAINER INSTALLED ADJACENT TO COOLER FLUID INLET. (REQUIRED FOR 30HW COOLERS.)

YESNO

CONDENSER PROTECTION:

IN-LINE MINIMUM 20-MESH STRAINER INSTALLED ADJACENT TO THE CONDENSER WATER INLET.

YESNO

TO START THE CHILLER: (insert check mark as each item is completed)

PLACE ON-OFF SWITCH IN THE ON POSITION.

ASSUMING THERE IS A CALL FOR CHILLED FLUID, THE COMPRESSOR WILL START UNLOADED AFTER A 6-SECOND TO 5-MINUTE DELAY (DEPENDING ON THE TIMING LOGIC).

THE LOW-PRESSURE SWITCH (ALL UNITS) AND OIL-PRESSURE SWITCH (30HL, HWA UNITS Ð ACCESSORY ON 30HK, HWB, HWC, HWS UNITS) ARE BYPASSED FOR 2 MINUTES.

IF ADDITIONAL CAPACITY IS REQUIRED AFTER THE 2-MINUTE PERIOD, COMPRESSOR WILL LOAD UP.

MEASURE THE FOLLOWING: WHILE MACHINE IS IN STABLE OPERATING CONDITION.

SUCTION PRESSURE

SUCTION LINE TEMP.

SUCTION SUPERHEAT

DISCHARGE PRESSURE

DISCHARGE LINE TEMP.

DISCHARGE SUPERHEAT

CHECK AND ADJUST SUCTION SUPERHEAT (9 to 11 F [5 to 6 C]).
