B. Preliminary Equipment Check (YES or NO)

IS THERE ANY SHIPPING DAMAGE?

 

IF SO, WHERE

WILL THIS DAMAGE PREVENT UNIT START-UP?

CHECK POWER SUPPLY. DOES IT AGREE WITH UNIT?

HAS THE CIRCUIT PROTECTION BEEN SIZED AND INSTALLED PROPERLY? (refer to Installation Instructions)

ARE THE POWER WIRES TO THE UNIT SIZED AND INSTALLED PROPERLY? (refer to Installation Instructions)

HAS THE GROUND WIRE BEEN CONNECTED?

ARE ALL TERMINALS TIGHT?

ON 30HW UNITS, IS THE THERMISTOR SECURELY STRAPPED TO THE COOLER LEAVING CHILLED FLUID LINE, AND IS IT PROPERLY INSULATED?

ON 30HW UNITS, IS YELLOW WIRE GOING TO TRANSFORMER 1 (POWER TRANSFORMER) ON THE CORRECT TERMINAL (TERMINAL H2 FOR 208 V AND 575 V; TERMINAL H3 FOR 230 V, 380 V, AND 400 V, TERMINAL H4 FOR 460 V)?

IF UNIT IS A MEDIUM TEMPERATURE BRINE UNIT, IS TEMPERATURE CONTROLLER SET FOR BRINE AND NOT FOR WATER? IF UNIT IS NOT A BRINE UNIT, IS TEMPERATURE CONTROLLER SET FOR WATER AND NOT FOR BRINE?

HAVE TEMPERATURE CONTROLLER, CONTROL MODULE AND CONTROL RELAY CONNECTIONS BEEN CHECKED FOR TIGHTNESS?

Manufacturer reserves the right to discontinue, or change at any time, speci®cations or designs without notice and without incurring obligations.
