Water and Drain
All models require connection to cold, potable water.
A hand actuated valve within sight of the machine
is required. There is a single 3/8” FPT inlet water
connection.
Water Filters
Install a new cartridge if the filters were used with a
prior machine.
All models require drain tubing to be attached to them.
There is a single ¾” 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 fitting.
Note: This NSF listed model has a 1" anti-back flow
air gap between the potable water inlet tube end and
the highest possible reservoir water level, no back
flow device is required.
2. Connect drain tubing to drain fitting.
3. Route the drain tubing to building drain. Follow
local codes for drain air gap. Use rigid drain tubes
and route them separately – do not Tee into the bin’s
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.
