Conair UGH016/0500 manual Filling The Chiller, Attach water hose to Fill/Drain valve

FILLING THE CHILLER

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:

1	Attach water hose to Fill/Drain valve.
2	Close the To Process and From Process valves.
3	Open the Fill/Drain valve and fill chiller
	to the fill mark on the Water Level sight glass. If the
	chiller is overfilled, the excess water spills out the vent
	tube. DO NOT OVERFILL.

4	Close the Fill/Drain valve.
5	Disconnect water hose from Fill/Drain valve.
