Drains
All models require drain tubing to be attached to them.
Air cooled models have a single ¾” FPT drain fitting
in the back of the cabinet. Water cooled models have
the same fitting plus an additional ½” FPT drain fitting
in the back of the cabinet. Install new tubing when
replacing a prior ice machine, as the tubing will have
been sized for the old model and might not be correct
for this one.
1. Connect water supply to water inlet fittings.
Note: This NSF listed model has a 1" anti-back
flow air gap between the end of the water inlet tube
and the highest possible reservoir water level, no
additional back flow device is required for the potable
water inlet.
2. Connect drain tubing to drain fittings.
3. Route the drain tubing to building drain. Follow
local codes for air gap.
Use rigid drain tubes and then route them separately
– do not Tee into the bin’s drain or, if water cooled,
Tee the condenser drain into the reservoir or bin drain.
Vent the reservoir drain. A vertical vent at the back of
the drain, extended about 8 – 10” will allow the gravity
drain to empty and also keep any surges during
draining from discharging water.
Horizontal runs of drain tubing need a ¼” per fall per
foot of run for proper draining. Follow all applicable
codes.
