þ  Check for proper pump rotation direction. To confirm proper 

rotation: 

1.  Observe a pump pressure gauge connected to the 

suction and discharge sides of the pump casing through 
two ¼” (approx. 6.4 mm) gauge cocks. 

2.  Close the gauge cock leading to the pump suction and 

open the gauge cock leading to the pump discharge. 

3.  Close the discharge butterfly valve, crack it open, then 

start the pump and observe the gauge.  

•

  If the gauge indicates within 15 psi (103.4 kPa/1.03 

bars) below the pump curve, pump rotation is 
correct. Pump rotation is clockwise opposite the 
shaft end. 

•

  If the gauge indicates 20 psi (137.9 kPa/1.38 bars) or 

more below the pump curve, the pump is running 
backwards. Reverse rotation by interchanging any 
two power mains to the pump motor or starter. 

•

  Recheck the pressure to be sure it increased. 

þ  Check the water level in the pump tank to be sure the pump 

does not run dry while the system piping is being filled. 

þ  Check your work and proceed to the Startup procedure in the 

following section. 

 

 

1.  Start the chiller by pushing the 

 button on the control 

panel of the unit. 

2.  The touchscreen will display the Main Menu screen. 

3.  If your chiller has been setup to control the pump tank, the 

recirculation pump will turn on first, then after 5 seconds 
the process pump will turn on.  If configured with a standby 
pump, the lead/lag will control which pump turns on. 

4.  Fifteen (15) seconds after the last pump turns on the first 

compressor will turn on.  Based on the temperature of the 
water, the controller will turn on compressors every 15 
seconds. 

5.  Adjust the Freezestat cut-out, located in the main electrical 

enclosure, to 10°F (6ºC) below the process temperature set 
point you want.
