Model 8756To the Installer
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan, two 3/8” I.P.S. (for single-head units) or
two 1/2” I.P.S. (for double-head units) 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 single-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.
