Plumbing Requirements
All models require connection to cold, potable
water. A hand actuated valve within site of the
machine is required. There is a single 3/8” FPT
inlet water connection; a 3/8” FPT to 3/8” male flare
adapter is supplied with the machine and can be
used if desired.
Water Filters
If connecting to water filtration, filter only the water
to the reservoir, not to the condenser. Install a new
cartridge if the filters were used with a prior
machine.
All models require drain tubing to be attached to
the 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 fittings.
3/8" OD tubing is recommended.
Note: This NSF listed model has a 1" anti-back flow
air gap between the water inlet tube end and the
highest possible reservoir water level, no 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.
Drain Tubing:
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 out the vent.
Horizontal runs of drain tubing need a ¼” fall per
foot of run for proper draining.
Follow all applicable codes.
