Plumbing - Pump Model
Drains
There are two types of ice machine models, one
that drains by gravity and one that has an internal
drain pump.
Drain Pump Model drain installation
1. Locate the coil of 3/8" ID plastic drain tubing
secured to the back of the unit.
2. Route the plastic drain tube from the back of the
unit to the drain connection point.
The drain connection point can be as high as 10
feet above the ice machine. The drain pump
includes a check valve to prevent re-pumping
water in the drain hose.
IMPORTANT NOTE: Often an air gap is required
by local codes between the ice maker drain tube
and the drain receptacle.
Water Supply
The recommended water supply tubing is ¼ inch
OD copper. Stainless steel flex or reinforced PCV
tube may also be used. Install an easily accessible
shut-off valve between the supply and the unit. This
shut-off valve should not be installed behind the
unit.
The water connection is at the back of the cabinet.
Connect using a compression fitting, one is
supplied tied to the water inlet tube. When built in:
Coil enough tubing behind the machine so it can be
pushed into the cavity without kinking the tubing.
