þCheck 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.

þCheck the water level in the pump tank to be sure the pump does not run dry while the system piping is being filled.

þCheck your work and proceed to the Startup procedure in the following section.

5-5 Remote Air-Cooled SSC Series Startup

1.Start the chiller by pushing the Start 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.
