GRAVITY DRAIN PUMP MODEL DRAIN INSTALLATION

1. Place the ice machine in front of the installation opening. Adjust leveling legs to the approximate height.
2. Insert drain tube through the routing hole in the back panel.
3.  Remove the upper back panel if needed for access to drain connection.

Note: If you are connecting a gravity drain model and the drain opening has been located in the floor under the base
pan according to the pre install specifications, follow steps 3 through 5 to drain the unit through the base. If not,
proceed to step 6b.

4. Remove the clamp and barbed elbow and take off the plastic cover in the base pan below the drain hose.
5. Connect a straight 5/8” barbed connector to the drain hose, securing with the clamp removed in step 4.
6. Cut an 8” piece of 5/8” ID X 7/8” OD tygon (clear plastic) tubing. Slide one end of the tube onto the outlet of the

barbed connector and secure with a clamp. Leave the other end of the tube lying on the floor of the base pan until
the unit is positioned over the floor drain.

7. Route the drain tube. Either a) Insert the drain tube through the base pan into the floor drain or b) Route the drain

tube through the left hole in the lower back panel and connect to barbed elbow and secure with a clamp.

8. Reinstall any panels removed.

CAUTION

Restrictions in the drain system to the machine will cause water to back up into the ice storage bin and melt the ice. Gravity drain tubing
must be vented, have no kinks and slope to the building drain. Air gaps are typically required by local code.

WATER & DRAIN INSTALLATION

The recommended water supply tubing is 1/4” OD copper. Stainless steel flex or reinforced PVC 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 at the back
of the cabinet.  

When built-in:  Coil enough tubing behind the machine so it can be pushed
into the cavity without kinking the tubing.

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 can be as high as 10 feet (3.05 m) above the ice machine.  the drain pump includes a check valve
to prevent re-pumping water into the drain hose.

IMPORTANT NOTE: Often an air gap is required by local codes between the ice maker drain tube and the drain
receptacle.
