SSC Series Central Chilling Stations 
þ  Electrical connections must conform to all applicable codes. 
þ  Complete the chilled water 
TO
 and 
FROM PROCESS
 
connections. 
þ  The optional or field installed chilled water supply and return 
valves must be open. 
þ  Be sure the tank and chilled water circuit piping are filled with 
a water/glycol mixture. The water/glycol mix should provide 
freeze protection to 20°F below the leaving water temperature 
you’ve selected. 
þ  The air cooled condenser should have an adequate supply of air 
for proper operation. 
þ  Connect the main power to the unit and bump-start it to check 
for proper rotation direction. If the fans are operating 
backwards, reverse any two main power leads at the incoming 
terminal block. 
þ  Remove all tools, foreign matter and debris from the pump 
tank reservoir and piping. 
þ  Complete all piping leading to and from the pump tank. 
Observe all applicable codes. 
þ  Complete all electrical wiring. Observe all applicable codes. 
þ  Prepare all related equipment in the system for operation. 
 
Note:   
 
  Never switch contactor leads or motor leads for reversing 
rotation. 
  Do not use contactor or motor leads for phase matching. 
  Compressor noise from reverse rotation is noticeable. Do 
not run in this mode for more than ten (10) seconds. The 
compressor shuts off if run longer in this mode. 
  Reverse rotation can cause suction and discharge pressures 
to be approximately equal; amp draws are lower than 
normal
  If you discover that compressor rotation is reversed, correct 
it by switching any two main power leads into the 
disconnect switch or distribution block
 on the unit. 
þ  Open the 1” (approx. 25 mm) makeup water valve and allow 
the tank to fill until the automatic float valve shuts off. The 
float level should be adjusted so the standing water level is 8” 
(20 cm) from the top of the tank.
