Water Distribution System
Water Distributors.
The water distributors are located under the freezer cover at the top of the
freezer. These distributors may require occasional or periodic cleaning to remove solids and foreign
particles accumulated from the make-up water. The frequency of this cleaning operation will
depend on the characteristics of the water supply. The cleaning operation is needed when the inside
diameter of a large proportion of the ice becomes irregular (due to channeling of water), or if some
of the ice is opaque, or if there is a noticeable decrease in ice capacity.

To clean distributors, stop the unit and remove the freezer cover on top of the freezer. The water
distributors (one in each tube) may then be removed with pliers for cleaning. Use pliers on the
distributor’s top part with a twisting upward motion. Use care when removing distributors to avoid
distorting orifice holes or the body of the distributor. The distributors can be soaked in ice machine
cleaner to remove mineral buildup. Rinse distributors thoroughly before reinstalling and tap lightly
with a rubber mallet to seat them in the freezer tubes.

Water Tank. The production of opaque ice can indicate that the water in the water tank contains a
concentrated amount of solids or salts. Remove cover plate. Open drain valve (28). Clean tank
thoroughly by flushing out with a hose and scrubbing with a stiff brush. It may be necessary to
completely remove the water tank in order clean all surfaces. The tank has casters to simplify
removal. After cleaning, close drain (reinstall tank if necessary) and fill the water tank with fresh
water. When restarting the machine, be sure that the water pump is circulating water. It is possible
that air may have collected in the pump impeller housing and the pump may have to be stopped and
started several times to expel the air.
Freezer Cover.
A clear polycarbonate freezer cover is provided for visual inspection of the water
box and water distributors located at the top of the freezer. The cover should be removed and
cleaned if it becomes coated with deposits. Generally, if the freezer cover is coated with solids this
is a prime indicator that the other areas (i.e. water tank and distributors) also require cleaning.
! CAUTION !
The water distribution system is critical to proper machine operation.
Failure to maintain and clean water distribution components can
result in improper machine operation and compressor failure.
