DRAIN BUSHINGS
CAUTION: All plumbing installations must comply
with local building codes.
NOTE: coolers should not be connected to “soft” water
systems. Soft water will accelerate corrosion and
decrease the effective life of pads and cooler cabinet.
a. A water supply valve should be installed at a convenient
location to allow the water supply to be turned on and
off for servicing or winterizing. Minimum 1/4" diameter
tubing should be used to provide water to the cooler,
larger tubing should be used if the length is greater than
100 feet and reduced to 1/4" at the unit.
b. Install float valve in location and orientation as shown.
c. Route water line up the left stand pipe as shown in
figure 10
d. Place compression nut and ferrule over end of tubing.
e. Connect 1/4" tubing from water supply to float valve
f. Insert tube into float valve and tighten to secure.
