Conair Thermolater vacuTrac, User Manual

Page: 66 / 120

The isolated, or totally closed, circuit models separate the
cooling water from the process fluid, which is held in a reser-
voir inside the unit. This reservoir should be kept at least
three-quarters full of the process fluid.
You can check the fluid level
in the reservoir using the sight
glass on the back of the
Thermolator.
To fill the reservoir:
Disconnect and lockout power, and remove the
top panel of the Thermolator.
Locate the reservoir
near the top of the unit.
Locate the fill port at the top of the reservoir.
Refill the reservoir.
Monitor the level using the sight
glass on the back of the unit. Because IC units can use
pure water or glycol mixtures, make sure you are adding
the correct fluid for your application.
Replace the top panel of the Thermolator.

IMPORTANT: Do not use deionized water or gly-
col mixtures containing additives in a Thermolator.
Softened water or glycol mixtures with additives,
such as automotive fluids, can damage the
Thermolator. Glycol/water process loop mixtures
should use industrial-grade ethylene glycol only.
