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.

5-3 Water-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.

Note: If the recirculation pump does not turn on (or that the flow switch is not satisfied) the compressors will not be allowed to turn on.

6.Check the pump(s) amp draws and pressures. The amp draws must be within the pump(s) running load and service factor amps.

7.Operate the chiller, looking for leaks and listening for unusual noises or vibrations that could indicate improper operation.

5-4 Remote Air-Cooled SSC Series Startup Checklist

þCheck the shipping papers against the serial tag to be sure chiller size, type and voltage is correct for the process.

þCheck the transformer primary voltage connections to be sure they are configured for the electrical power you are using.

þThe voltage at the main power connection must read within plus or minus ten percent (±10%) of the voltage listed on the serial tag.

þPhase imbalance must be less than two percent (<2%).
