Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut- off valve. On the underside rear of the
base pan, two 3/8” I.P.S. water connections for inlet
and outlet have been provided for easy hook- up. 1/2”
inside diameter water lines should be connected to the
machine. (Flexible lines are recommended, if local
codes permit.) Depending on local water conditions, i t
may be advisable to install a water strainer to prevent
foreign substances from clogging the automatic water
valve. There will be only one water “in” and one water
“out” connection. DO NOT install a hand shut- off valve
on the water “out” line! Wa ter should always flow in this
order: first, through the automatic water valve; second,
through the condenser; and third, through the outlet
fitting to an opentrapdrain.
A back flow prevention device is required
on the incoming water connection side. Please
refer to t he applicable National, State, and local codes
for determining the proper c onfiguration.
