The process fluid, which can be water or a glycol mixture, is
held in a tank inside the unit. This tank should be kept at least
three-quarters full of the process fluid.
You can check the fluid level in
the tank using the sight glass on
the back of the chiller.
To fill the reservoir:
Locate the fill port at
the back of the chiller.
Refill the tank. Monitor
the level using the sight
glass on the back of the
unit. Because chillers can
use pure water or glycol
mixtures, make sure you are
adding the correct fluid for
your application.
