The reason for the separate water inlet connections is that some installations use a water tower for
cooling the water used in the water cooled condenser and some installations use treated water (filtered)
for the ice making inlet water connections. Be sure to install water line (incoming) to the 3/8” male flare
connection on the back of the unit that supplies water to the water regulating valve inside.
DRAIN
Provide a suitable trapped open drain as close as possible to the area where the ice maker is going to be
installed. This may be an existing floor or a 1-1/4” trapped open drain. Two separate drain lines are
required for air cooled units, one for the storage bin and one for the dump valve drain hose.
An additional separate drain line will be required for water cooled units from the outlet of the condenser
coil to the drain. Run all gravity drain lines with a good fall to the open drain.
All Plumbing Must Be Installed in Accordance with Local Codes.
NOTE: In some cases it may be necessary to insulate the water supply line and drain line. Condensate
dripping to the floor can cause serious staining of carpets or hardwoods.
DRAIN CONNECTION INSTALLATION INSTRUCTIONS
Taking care not to kink or collapse vinyl tubing at any point, route tubes to any open, trapped or vented
floor drain. Run tubing to drain separately. Do not tee any drain hoses together. Add drain tubing required
to reach floor drain.
Typical installation: All electrical and plumbing must be done per local codes.
