FILLING THE
CHILLER
Portable Chillers UGH024/1103
3-6 INSTALLATION
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 eth-
ylene glycol or propylene glycol solution (see Percent Glycol
vs. Temperature chart).
To fill with water:
Attach water hose to Fill/Drain valve.
Close the To Process and From Process
valves.(Factory Optional)
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.
Check the coolant level.
When the chiller is turned on the coolant level drops as
the coolant begins to circulate, filling the connected
plumbing. Check the coolant level on the back of the
chiller. The coolant level shows on the water level gauge.
Make sure coolant level is filled to the mark on the
gauge. Add more if needed.
Disconnect water hose from Fill/Drain valve.
