The chiller is shipped without coolant. The chiller is manually filled during installation using water as its coolant.

For atypical process temperatures below 45°F {7.2°C}, use the table below to determine the percentage (by volume) of glycol needed for the process temperature that is required. Mix the proper percentage of glycol with water.

IMPORTANT: The chiller’s control does not monitor the percentage mixture of glycol.

To fill with water:

1Attach the water supply to the Fill/Drain valve, located on the back of the chiller.

2Open the “To Process” and “From Process” valves (factory optional).

3Open the Fill/Drain valve or water supply and fill the chiller to the 7/8 full level on the water level gauge. If the chiller is overfilled, the excess water spills out the vent tube. DO NOT OVERFILL.

4Close the Fill/Drain valve.

5Check the coolant level. When the chiller is turned on the coolant level drops as it begins to circulate, filling the connected plumbing. Check the

coolant level on the back of the chiller. Make sure the coolant level is filled to the 7/8 full level on the water level gauge. Shut down the chiller and add more coolant, if needed.

6Disconnect water hose from Fill/Drain valve, if the chiller is to be used elsewhere.
