Chiller with Reservoir
The reservoir can be filled by removing the water fill cap located on the upper rear of the Chiller (See Fluid Rec-
ommendations page). After ensuring that the drain valve is closed, fill the reservoir via the full port with clean
water until the water level sight glass on the front of the unit indicates “FULL” the fill cap should then be rein-
stalled before operation begins.
Auto Refill Option
If the Chiller is provided with the Auto Refill Option, install 1/4–inch or 1/2–inch tubing from the auto refill fitting
located on the lower rear of the Chiller to a fresh water supply line. The Chiller reservoir will fill with water auto-
matically and the proper reservoir level will always be maintained.
Chiller without Reservoir
The Chiller and system piping should be filled with clean water ensuring that all air is purged from the system.
