The design of the float valve and reservoir prevents
potable water backflow by means of a 1" air gap
between the reservoir's maximum water level
and the float valve water inlet orifice.
Drain
There is one ¾” FPT condensate drain fitting at
the back of the cabinet.
Attach Tubing

water fitting,

” OD copper tubing or the equivalent
is recommended.
Water filtration is recommended. If there is an
existing filter, change the cartridge.
Drains - use rigid tubing: Connect the drain tube to
the condensate drain fitting. Vent the drain.
Do not Tee ice machine drains into the drain tube
from the ice storage bin or dispenser. Back ups
could contaminate and / or melt the ice in the bin or
dispenser. Be sure to vent the bin drain.
Follow all local and national codes for tubing, traps
and air gaps.
