Exterior shut-off valves must be provided in the water inlet lines.
The minimum inlet water pressure for satisfactory operation of the machine is 30 psig.
The maximum allowable pressure is 100 psig.

Water Supply and Drains
The condenser water outlet, water tank drain, drip drain and ice storage bin drain connections
must be extended to an open drain or sump and arranged for visible discharge. See FIGURE-7
for water and drain connections on machine. See FIGURE-8 of typical space diagram drawing
for ice storage bin drain connection.
! CAUTION !
These lines must NOT be connected into a pressure tight common header
due to the possibility that warm condenser water
may back up into the water pan, drip pan or the ice storage bin. The
condenser water outlet MUST be piped separately to the drain.
! CAUTION !
Note: Above drawing shown with plastic side casings (1/2” thick)
