Maintenance - Delfield KCM-50 Service And Installation Manual

Shelleyglas ® /Shelleysteel™ Service and Installation Manual
PRESSURE CONTROL SETTINGS
All Delfield refrigerated models come equipped with
115-volt, 60 cycle, single phase refrigeration units. The
refrigeration valves are open and ready to operate as soon
as the power supply cord is plugged into the standard 115-
volt, grounded electrical outlet.
Pressure Control
The temperature is controlled by an adjustable pressure
control located in the machine compartment. An adjustable
control has the word COLDER near the knob, with an arrow
to indicate the adjustment direction. These controls are
field adjustable and do not require a service agent. If you
have any questions, feel free to contact the Delfield Service
Department.
In attempting to adjust the pressure control,
you can do damage to your unit by accidentally
adjusting the differential. Please make small
incremental adjustments if a temperature
adjustment is necessary, please contact the
service department at Delfield (800) 733-8821
or your local service agent. Delfield is not responsible
for charges incurred while having the pressure control
adjusted.

MAINTENANCE

Defrosting
Refrigerated cold pans and frost tops should be defrosted
daily. Milk or Ice Cream dispensers require defrosting after
3/8" to 1/2" of frost forming. On/Off switch located above
louver panel.
Never use sharp objects or tools to clean or
scrape ice/frost build up from the refrigerated
cold pans or frost tops. A puncture to the
pan could cause irreparable damage to the
refrigeration system.
Units with a Eutectic Fluid Cold Pan require the
same precautions. The fluid is NOT refillable
and loss of fluid due to a puncture would cause
irreparable damage.
Over shelves and other items mounted to the top of the
counters should never be installed in the field due to the
potential damage to the refrigeration system.

Cleaning the unit
To clean refrigerated understorage, use mild soap and water.
For all fiberglass and stainless steel parts, use a mild, non-
abrasive soap or detergent and warm water. This may be
followed by an application of stainless steel cleaner or polish
which will eliminate water spotting, fingerprints and bring
out the color of the fiberglass.
To maintain the rich, brilliant color of the fiberglass and to
remove shallow surface scratches, wax twice a year. This can
be done in the same manner in which a car is waxed.
Casters
Casters can be lubricated with penetrating type oil.
Recommended maintenance schedule
Daily: Wipe and/or wash food wells, unit surface, any
refrigerated understorage and door gaskets.
Monthly: Remove louvers and clean condensing coil with
a soft brush, such as a fin comb, or vacuum cleaner brush
attachment. The object is to remove dust and webs from
fins without bending them. Check casters for any debris that
could be binding the wheels such as strings from mops or
bits of paper.
Every six months: Wax fiberglass body and if necessary,
lubricate casters.
