B. Clean the exterior surfaces of the compressor, agitator motor, fan motor and fan blade with a damp cloth to
remove accumulated dust.
3. Ice Water Bath Cleaning
A. In order to maintain maximum cooling efficiency, the water bath should be cleaned two to four time annu-
ally, depending on local conditions and/or as required by state and local health departments.
B. 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.
C. Remove the cup rest and splash panel to access the water bath drain hose. Remove the cap from the drain
hose and extend the hose to a suitable waste receptacle and allow the water bath to drain.
D. Remove the top, side and rear panels as well as the merchandiser. Unplug the harnesses from the mer-
chandiser and top panel.
E. Disconnect the red, white and blue 12–pin connectors as well as the white 2–pin connector from the elec-
trical box.
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 probe of the ice bank con-
trol. 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.
F. Once the ice bath is sufficiently melted, remove the two hitch pins securing the refrigeration deck to the
water bath tank and lift the deck using the two handles.
G. Prepare 1 gallon (3.8 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.
H. Using the solution in the water bath, the fiber brush and a clean cloth soaked with solution, clean the refrig-
eration deck's evaporator coils, agitator motor shaft and blade and the ice bank sensing probe.
I. Drain the cleaning and sanitizing solution from the water bath and rinse/flush all the components with clean
water.
J. Re-install the refrigeration deck into the water bath and secure the hitch pins.
K. Plug the connectors into their appropriate receptacles on the electrical box.
L. Fill the water bath with cool potable until water begins to trickle from the overflow tube.
M. Install the top, side and rear panels as well as the merchandiser. Connect the harnesses from the mer-
chandiser and top panel to their appropriate terminals.
N. Plug the dispenser into the electrical outlet and turn the unit on.
