The Chiller is shipped without coolant. The chiller is filled
manually during installation. Use water as the coolant down to
40 °F (4 °C). Below 40 °F and down to 20 °F (-7 °C), use an
ethylene glycol or propylene glycol solution.
To fill with water:
Attach water hose to Fill/Drain valve.
Close the To Process and From Process valves.
Open the Fill/Drain valve and fill chiller
to the fill mark on the Water Level gauge. If the chiller is
overfilled, the excess water spills out the vent tube.
DO NOT OVERFILL.
Close the Fill/Drain valve.
Disconnect water hose from Fill/Drain valve.

To fill with glycol solution:
Mix the glycol to the proper percentage.
Use the table to determine the percentage (by volume) of
glycol needed for the process temperature (in °F) you
require. Do not choose a temperature below 15 °F (-9 °C).
Mix the proper percentage of glycol with water.
