MAINTENANCE: DISH DISPENSERS
Unheated dish dispensers
Lift the dispenser out of the counter or CAB cart by grasping
the black dish guides and lifting straight up and out. Remove
any debris that may be in the assembly with a damp cloth.
Clean the stainless steel by using a soft cloth, soap and
warm water. If this is not sufficient, try ammonia and water
or a non-abrasive liquid cleaner. Rub with the grain of the
stainless steel to avoid marring the finish. When cleaning
is completed, insert the dispenser assembly back into the
counter or CAB cart.
The bottom rails on the CAB cart should be cleaned
occasionally. They may be accessed most easily through the
bottom of the unit.
Do not use abrasive cleaner because it will scratch
the stainless steel and plastic.
Mobile and built in chilled plate and mug
dispensers
The interior and exterior can be cleaned using soap and
swarm water. If this is not sufficient, try ammonia and water
or a non-abrasive liquid cleaner. When cleaning the exterior,
always rub with the "grain" of the stainless steel to avoid
marring the finish. Do not use an abrasive cleaner because it
will scratch the stainless steel and plastic.
In order to maintain proper refrigeration performance, the
condenser fins must be cleaned of dust, dirt and grease
regularly. It is recommended that this be done at least every

Possible Cause
three months. If conditions are such that the condenser is
totally blocked in three months, the frequency of cleaning
should be increased. Clean the condenser with a vacuum
cleaner or stiff brush. If extremely dirty, a commercially
available condenser cleaner may be required.
Heated dish dispensers
Heated units must be disconnected from the main
power source and allowed to cool down before
cleaning. Cords on DIS models used as drop-ins
into a counter or into another piece of equipment

are directly connected to the power source. On
CAB units there is a cord from each individual
DIS tube to a central receptacle on the cart and
D A NG E R
a separate cord from that receptacle to the main
power source. Never hose down units with water.
