HOLDING MODULE
For Recommended Holding Temperatures,
see HM2000 guidelines on page 7.
When equipped with a holding module, your
cabinet is designed to maintain the
temperature of HOT prepared foods. The
holding module is equipped with a
thermostatically controlled heater, a blower
for air circulation and a water pan. A POWER
switch is provided with a red light to indicate
when the unit is switched ON. Beside the
POWER switch is the TEMPERATURE
thermostat and its yellow indicator light.
A three-wire grounded lead cord is supplied
fixed to the module. The cord cannot be
separated from the module, thus, upon
module removal be careful of the cord
passing through the cabinet wall. Likewise
when installing the module into a cabinet, the
cord must first be fed through the opening in
the cabinet back panel.
1. With the POWER switch OFF, plug the cord
into a standard grounded 20 amp, 125VAC
receptacle. REFER TO CABINET DATA
PLATE FOR AMPERE RATING.
CAUTION: THE WATER PAN MUST BE IN
PLACE DURING MODULE OPERATION.
2. To introduce limited humidity, fill the 11/2-quart
capacity water pan to 1/2" from the top with
HOT clean tap water. During operation,
check the water level every 3 hours and refill
as necessary. The unit may be operated
without water if humidity is not desired.
3. Snap POWER switch to ON. The red POWER
light will now glow as will the yellow indicator
light, and the blower will begin circulating air.
NOTE: This is not a foot switch. Using it as
a foot switch can damage the switch and
make the cabinet inoperable.
4. Turn the TEMPERATURE thermostat to
a setting of 10. The holding unit is now
in operation.
5. After allowing the cabinet to PREHEAT FOR
APPROXIMATELY 45/60 MINUTES, reduce
the thermostat setting to 6/8. In a room of
average temperature (72°F), this should
provide 150°-170°F. Adjustments to the
temperature may be made as necessary.
THIS IS A HOT FOOD HOLDING CABINET AND
IS NOT INTENDED TO RETHERMALIZE COLD
FOOD. MAKE SURE FOOD AND CABINET ARE
AT PROPER TEMPERATURES BEFORE
PLACING FOOD IN THE CABINET.
NOTE: The POWER (red) light will glow as soon
as the POWER switch is switched ON and will
continue to glow until switched OFF. The yellow
indicator light will go on and off as the thermostat
cycles. The blower will operate as long as the
POWER switch is ON. If the yellow light is not
illuminated, this indicates that the cabinet has
achieved the preset TEMPERATURE level, NOT
that the unit has been switched OFF.
It is not necessary at the end of the operating
day to disrupt the TEMPERATURE setting in
order to turn the unit OFF. By switching the
POWER switch to OFF, the unit is no longer
operating. By switching the POWER switch to
ON when resuming operations, the cabinet
will attain the preset level.

setting 10 and TEMPERATURE thermostat to
setting 2. Given a normal room temperature of
72°F, a PREHEAT TIME OF APPROXIMATELY
30 MINUTES is required before proofing can
begin. For products that require more than 45
minutes to proof, it will probably be
necessary to reduce the HUMIDITY setting to
avoid a 100% relative humidity condition
during the proofing cycle. HUMIDITY
SETTINGS THAT ARE TOO HIGH WILL
RESULT IN EXCESS WATER CONDENSING
ON THE INSIDE OF THE DOOR AND
POSSIBLE CABINET LEAKAGE.
COMBINATION HOLDING/PROOFING
MODULE
For Recommended Holding Temperatures,
see CM2000 guidelines on page 7.
When equipped with a combination holding/
proofing module, your cabinet is designed for
proofing dough products (proof mode) or
maintaining the temperature of HOT prepared
foods (heat mode). The combination holding/
proofing module is equipped with three
thermostatically controlled heaters, a blower
for air circulation and a water pan. A POWER
switch is provided with a red light to indicate
when the unit is switched ON. Beside the
POWER switch are the TEMPERATURE and
HUMIDITY thermostats, each with a yellow
indicator light. Located between the
thermostats is the switch for selecting PROOF
mode or HEAT (holding) mode operation.
Individual adjustments of temperature and
humidity may be made as necessary.
NOTE:The POWER (red) light will glow as soon
as the POWER switch is switched ON and will
continue to glow until switched OFF. The yellow
indicator lights will go on and off as their
controls cycle; the blower will operate as long as
the POWER switch is ON. If the yellow lights are
not illuminated, this indicates that the cabinet
has achieved the preset levels, NOT that the
unit has been switched OFF.
It is not necessary at the end of the operating
day to disrupt the TEMPERATURE and
HUMIDITY settings in order to turn the unit OFF.
By switching the POWER switch to OFF, the unit
is no longer operating. By switching the POWER
switch to ON when resuming operations, the
cabinet will attain the preset levels.
A three-wire grounded lead cord is supplied
fixed to the module. The cord cannot be
separated from the module, thus, upon
module removal be careful of the cord
passage through the cabinet wall. Likewise
when installing the module into a cabinet, the
cord must first be fed through the opening in
the cabinet back panel.
Heat Mode Operation
In the HEAT mode, the TEMPERATURE
thermostat controls one heat element in the air
duct to produce dry heat.
Proof Mode Operation
In the PROOF mode, the HUMIDITY
thermostat controls the heat element under
the water pan to produce moist heat
(humidity) while the TEMPERATURE
thermostat controls the heat element in the
air duct to produce dry heat.

IV. CLEANING INSTRUCTIONS
a. Isopropyl (rubbing) alcohol, used as a
cleaner, will aid in removing grease
smudges and fingerprints.
CAUTION
AT NO TIME SHOULD THE MODULE OR
CABINET BE WASHED OR FLOODED WITH
WATER OR LIQUID SOLUTION. NEVER
STEAM CLEAN. SEVERE DAMAGE OR
ELECTRICAL HAZARD COULD RESULT.
1. Turn off master switch.
2. Disconnect the unit from its power source.
WARNING
ALLOW THE UNIT TO COOL BEFORE
CLEANING, AS THE INTERIOR OF THE
CABINET MAY BE HOT ENOUGH TO BURN.
ALSO ALLOW THE WATER IN THE PAN TO
COOL BEFORE REMOVAL.
3. Open the door(s) and remove the slide racks
and chimney.
4. If there is water in the pan, remove and empty.
5. Remove the module from the cabinet by
lifting up the front enough to clear its detent,
then pull the module away from the cabinet.
The power cord slips through the clearance
hole at the rear of the cabinet.
b. A small amount of liquid dish detergent in
a bucket of water will help remove heavier
dirt and will help make the clear panel
antistatic and therefore less likely to
attract dust.
c. A paste-wax recommended for
polycarbonate plastics and approved for
food service equipment will hide small
scratches and return the luster and clarity
to the clear door panel as well as reduce
the electrostatic attraction of dust.
3. Do not neglect to clean the under-chassis
area, especially the area above each caster.
4. The cabinet or component(s) must be
thoroughly rinsed to remove any residue that
may stain the materials.
5. When choosing a cleanser, make sure the
cleanser manufacturer recommends its use
on natural and epoxy-coated aluminum.
B. GENERAL CLEANING INSTRUCTIONS
6. Do not use abrasive cleaners. For every
cleaning method, best results are always
obtained when the cleaner and technique
are matched to the soil conditions involved.
Contact your detergent representative to
ensure the cleaning product being used is
recommended for use on natural and epoxy
coated aluminum. Follow the manufacturer’s
directions on cleaners. Never mix cleaners.
1. LIGHT SOIL
If routine (daily) cleaning is practiced, a mild
soap and warm water should be sufficient to
keep the unit clean.
2. HEAVIER SOIL
If cleaning has been postponed, solvent or
emulsion type cleaners that can be applied
with bare hands will give excellent results.
Such cleaners are available under various
brand names and detergent suppliers can
recommend materials appropriate for use on
natural and epoxy-coated aluminum.
7. After cleaning, replace all components.
Make sure the slide racks and chimney are
seated in the hangers correctly.
A. SPECIFIC CLEANING INSTRUCTIONS
NOTE: For every cleaning method, best results
are always obtained when the cleaner and
technique are matched to the soil conditions
involved. To ensure using the proper cleaner for
natural and epoxy-coated aluminum, contact
your detergent representative.
1. Do not immerse the module when cleaning.
Instead, use a damp cloth and a drying
towel. Special attention should be paid to
keeping the air-inlet area and the controls
area free of dirt build-up. BE SURE TO
THOROUGHLY DRY THE MODULE BEFORE
RETURNING IT TO USE.
2. The protective masking on the polycarbonate
door may be removed by simply peeling it
from the door, starting at a top corner and
working downward. Should the masking be
difficult to peel, polycarbonate sheet
demasking agents are commercially
available and give excellent results. For
regular cleaning, a soft cotton flannel cloth
and a cleaner recommended by its
manufacturer for use on polycarbonate
plastics is suggested. Do not use synthetic
cloths or cleaners not intended for
polycarbonate plastics as these will scratch
and dull the polycarbonate door panel.
Additional hints for keeping the door
panel clean and clear:

V. MAINTENANCE
A. CABINET MAINTENANCE —
ALL MODELS
Your C175 series cabinet has been
designed to require very little maintenance.
With normal use, cleaning is the only form of
maintenance that need be done on a regular
basis. Keeping the casters free of dirt buildup will go a long way in prolonging their life.
If your cabinet is rolled over rough surfaces
or transported over-the-road, the various
threaded fasteners, i.e., screws and nuts,
should be periodically inspected and
tightened if necessary, particularly the
transport latch, hinge and caster fasteners.
B. MODULE MAINTENANCE
The module in the base of your cabinet has
also been designed to require very little
maintenance. With normal use, cleaning is
the only form of maintenance that need be
done on a regular basis. When cleaning, do
not spray or pour water on the module and
do not immerse the module in water. Wipe
with a damp cloth and dry with a towel.
Keeping vital areas such as the air-inlet area
and the controls area free of dirt build-up will
go a long way in prolonging the life of the
electrical components. No maintenance is
required on the electrical components.
C. BLOWER MOTOR MAINTENANCE
The blower motor bearings should be
lubricated annually.
1. To gain access to the motor, follow the
instructions listed on page 12.
2. Remove the (2) rubber plugs, (1) located
at each end of motor.
3. Apply 6 drops of a SAE 20 non-detergent
oil to each bearing and re-install plugs.
4. Re-assemble module.

MODULES — ALL MODULES
Your module has been designed to be userserviceable, assuming a basic knowledge of
the operation of electrical devices. This section
has been written to guide the user step by step,
and in layman’s terms, through the dismantling
and servicing of the module. Before attempting
to service your module, read the appropriate
Module Repair Procedures (found elsewhere in
this section) thoroughly. If you do not
understand the Repair Procedures or prefer not
to service your module yourself, or if your
warranty is still in effect, please contact our
Customer Service Department for the factory
authorized service agency nearest you.
d. Unfasten the electrical cover by removing the
three screws along the front of the module
and the two screws along each edge of the
module. Retain this hardware for re-assembly.
e. Open the module by raising the
component chassis from the electrical
cover and placing the chassis top down
on a dry, non-flammable work surface. IF
NECESSARY TO RECONNECT THE
OPENED MODULE TO A POWER
SOURCE, PRACTICE EXTREME CAUTION
SO AS NOT TO RECEIVE ELECTRICAL
SHOCK FROM EXPOSED COMPONENTS.
DANGER: HAZARDOUS VOLTAGE.
DISCONNECT POWER BEFORE SERVICING
OR CLEANING.
2. Refer to the appropriate Module
Replacement Parts Diagram to identify the
internal components. Determine
malfunctioning component(s) by electrical
diagnostic procedures.
The lead cord plug configuration designates
whether your module uses a 15 or 20 amp
service. Refer to the illustration below to
identify the two different plugs.
15 AMP PLUG
3. After servicing, be sure to verify the routing
of each wire with the appropriate wiring
schematic before installing electrical cover
and connecting module to power source.
Be sure that the thermostat sensor tube
does not contact any electrical connections.
20 AMP PLUG
4. Assemble components using the retained
hardware, making sure that no wires are
pinched between the cover and the
component chassis.

5. Install water pan. Then, feed cord through
clearance hole in cabinet and slide module
into cabinet.

MODULES
CAUTION: IT IS IMPORTANT THAT ALL
SAFETY PRECAUTIONS PERTAINING TO
THE SERVICING OF ELECTRICAL
DEVICES BE OBSERVED AT ALL TIMES.
1. Dismantle your module for servicing per the
following instructions.
NOTE: To replace the Thermostat Knob or water
pan, it is not necessary to dismantle the module.
a. Make sure the lead cord is not plugged into
an outlet. Be certain that the module and any
water in the water pan has cooled to a
temperature safe for handling.
b. Remove module by lifting the front
enough to clear the detent, then pull the
module from the cabinet, grasping it with
both hands as it clears the cabinet. The
cord should slip through the clearance
hole in the back of the cabinet.
