Gravity Drain
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.
1. Place the ice machine in front of the
installation opening. Adjust leveling legs to the
approximate height.
2. Remove the front service access panel and the
upper back panel.
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.
3. Remove the clamp and barbed elbow and take
off the plastic cover in the base pan below the
drain hose.
4. Connect a straight 5/8” barbed connector
to the drain hose, securing with the clamp
removed in step 3.
5. 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.
6. 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.
Note: Add a vertical vent in a horizontal drain tube
to reduce internal pressure and improve drainage.
7. Reinstall the upper back panel.
8. Reinstall the service access panel. Level the
unit.
