CONNECTING POWER (FOR UNITS WITHOUT HEATER OPTION)
In order to avoid an electrical potential at the chiller frame due to insulation failure, a proper
ground connection to the system must be provided. Failure to do so could result in damage to
the equipment, personal injury, and/or death.
Connect a 3-conductor SJT type power cord with an IEC 320/C19 receptacle to the inlet power to the module
on the rear of the unit and to an appropriate AC power source. All chillers should use a 12-gauge power cord.
Startup Procedure
1. Turn "ON" the circuit breaker on the rear of the unit. The controller will go through a diagnostic test. Turn
on the chiller unit using the top left key located on the Keypad Display panel. The controller displays "OFF"
for 8 seconds. The delay prevents rapid cycling of the compressor using the "ON" and "OFF" switch. If
your chiller is equipped with control package 2 or 3 the fault shut off may prevent the chiller from starting up.
If the chiller displays an alarm after pushing the “ON” button disable the fault shutoff on the customer menu
and restart the chiller.
2. Adjust the temperature set point using the controls on the keypad display as follows:
Press the “SET” key once to display the current coolant temperature set point.
Press the “UP” or “DOWN” arrow key until the desired coolant temperature set point appears on the
LED display.
Press the “SET” key again to accept the set point and return to normal operation.
3. Operate the chiller for a short time and then check the coolant level in the reservoir. If the level drops, add
more coolant.
4. Check all fittings and hoses for fluid leaks. If a leak exists turn chiller off, disconnect power and take
necessary action to repair the leak.
Please Note:
During initial start up the temperature display may occasionally appear to be dim. This is a normal occurrence
and does not indicate that there is problem with the chiller. After 10 seconds the display will brighten to its
normal level.
