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 1/2” 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, it
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 for both s ingle--head and
double--head units. DO NOT install a hand shut--off
valve on the water “out” line! Water 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 the applicable National, State, and local codes
for determining the proper configuration.
