with a vacuum cleaner or a soft bristle
brush.
e. Clean the exterior surfaces of the
compressor, agitator motor, fan motor, and
fan blade with a damp cloth to wipe off the
accumulated dust.
Ice Water Bath Cleaning
The water bath should be cleaned to obtain
maximum cooling efficiency. It is recommended
that the water bath be cleaned two to four times
annually, depending upon local conditions
and/or as required by state and local health
departments.
A convenient time to do this is at the time the
dispenser is being sanitized. To save time, the
water bath can be drained while the dispenser is
being sanitized.
a. Remove the cup rest and splash panel to
access the water bath’s drain hose. Extend
the drain hose to a suitable waste receptacle
and allow the water bath to drain.
b. Remove the dispenser’s top bonnet by
removing the two screws located on the top
of the bonnet. While lifting the bonnet up
and away from the dispenser, unplug the
merchandiser electrical cord from the power
strip located on the refrigeration deck.
c. In order to remove the refrigeration deck for
the water bath and evaporator cleaning,
remove the two screws that secure the deck
to the cabinet structure. Unplug the
refrigeration deck’s main power strip cord
from the dispenser’s power cord. Disconnect
the red, white and blue 12 pin plugs from the
electrical box. Disconnect the key switch a
by unplugging the white 2 pin plug at the
transformer.
Note: It will be necessary to melt the ice bank
to be able to pull the refrigeration deck up and
away from the dispenser. Warm water may be
used to accelerate the melting. In order to
prevent ice bank control damage, do not direct
the warm water stream on to the sensing bulb
of the ice bank control. Never use an ice pick
or other instrument to remove ice from the
evaporator. Such practice can result in a
punctured refrigerant circuit or damage to the
water bath tank.
d. Once the ice bank is sufficiently melted, lift
the entire refrigeration deck up and away
from the water bath by lifting the deck using
it’s service handle strap.
e. Prepare 1 gallon (3.9 L) of cleaning and
sanitizing solution (see “Sanitizing the
Concentrate Lines & Valves”). Pour the
cleaning and sanitizing solution into the
water bath and clean the sides and bottom of
the tank, the product coils, and associated
brackets with a fiber brush.
f. Utilizing the cleaning and sanitizing solution
in the water bath, the fiber brush, and a
clean cloth soaked with sanitizing solution,
clean the refrigeration deck’s evaporator
coils, agitator motor shaft and blade, and the
ice bank sensing bulb.
g. Drain the cleaning and sanitizing solution
from the water bath and rinse/flush all the
components with clean water.
h. Re-install the refrigeration deck into the
water bath and secure with two screws.
i. Connect the refrigeration deck’s power strip
to the dispenser’s power cord. Connect the
red, white and blue 12 pin plugs to the
electrical box. Connect the key switch to the
transformer.
j. Fill the water bath with cool potable water
until water begins to flow from the overflow
tube.
k. Plug the merchandisers power cord into
power strip located on the refrigeration deck
and re-install the top bonnet. Secure the
bonnet assembly with two screws.
l. Install the splash panel and cup rest and plug
the dispenser’s power cord into the electrical
outlet.
