Installation: Water & Drain
The recommended water supply tubing is ¼ inch
OD copper. Install an easily accessible shut-off
valve between the supply and the unit. This shut-off
valve should not be installed behind the unit.
Note: Do not use self-piercing type valves.
1. Remove the front service panel.
2. Route the tubing through the right hole in the
back to the inlet water solenoid valve inlet.
3. Install a compression fitting on the tubing and
connect to the inlet of the solenoid.
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.
