Electrical Service
DANGER
Check all wiring connections, including factory
terminals, before operation. Connections can become
loose during shipment and installation.
Warning
n
This appliance must be grounded and all field wiring
must conform to all applicable local and national
codes. Refer to rating plate for proper voltage. It is the
responsibility of the end user to provide the disconnect
means to satisfy the authority having jurisdiction.
VOLTAGE
All electrical work, including wire routing and grounding,
must conform to local, state and national electrical codes.
The following precautions must be observed:
• The equipment must be grounded.
• A separate fuse/circuit breaker must be provided for
each unit.
• A qualified electrician must determine proper wire size
dependent upon location, materials used and length
of run (minimum circuit ampacity can be used to help
select the wire size).
• The maximum allowable voltage variation is ±10% of
the rated voltage at equipment start-up (when the
electrical load is highest).
• Check all green ground screws, cables and wire
connections to verify they are tight before start-up.
GROUND FAULT CIRCUIT INTERRUPTER
Ground Fault Circuit Interrupter (GFCI/GFI) protection is
a system that shuts down the electric circuit (opens it)
when it senses an unexpected loss of power, presumably
to ground. Manitowoc does not recommend the use of
GFCI/GFI circuit protection to energize our equipment. If
code requires the use of a GFCI/GFI then you must follow
the local code. The circuit must be dedicated, sized
properly and there must be a panel GFCI/GFI breaker. We
do not recommend the use of GFCI/GFI outlets to energize
our equipment as they are known for more intermittent
nuisance trips than panel breakers.
RATED AMPERAGES, HORSEPOWER, VOLTAGE &
POWER CORD CHART
CAB & T series units with plugs are supplied with
approximately 9ft (2.7m) cords.
DIS series units with plugs are supplied with approximately
4ft (1.2m) cords.
DIS models plug into a wall receptacle when used as dropin models. If they are grouped together in a CAB model,
all of the individual DIS power cords are plugged into the
receptacle in the CAB cabinet. The master power cord on
CAB models plugs into a wall receptacle.

Do not operate any appliance with a damaged cord
or plug. All repairs must be performed by a qualified
service company.
DANGER
Never stand on the unit! They are not designed to
hold the weight of an adult, and may collapse or tip if
misused in this manner.
Warning
n
Do not contact moving parts.
Warning
n
All covers and access panels must be in place and
properly secured, before operating this equipment.
Dish Dispenser Loading Instructions
Caution
,
Keep fingers clear from the edge of the opening.
Only load a manageable stack of dishes at a time,
approximately 4” - 5” (10.2cm - 12.7cm). Each DIS model
dispensing tube will accommodate a 26” (66cm) stack of
plates or bowls.
If the stack is over the guide posts and is bottomed out, it is
full. If stack is over guide posts and not bottomed out (the
stack will bounce up and down), adjust the springs. See
“Field adjustment” instructions.
Caution
,
Do not block the supply and return air grills or the air
space around the air grills. Keep plastic wrappings,
paper, labels, etc. from being airborne and lodging in
the grills. Failure to keep the air grills clear will result in
unsatisfactory operation of the system.

Operation Section 3
Dish Dispenser Temperature Adjustment – ET
Models Only
Warning
n
If adjusting a heated model, unplug the unit. Allow the
unit to cool completely before handling.
ET (even-temp) models have either a 400 or 700 watt
heating element and an adjustable thermostat. The
factory setting for thermostat is A, operating temperature
of approximately 165°F (74°C) and effective plate
temperatures of between 110°F - 120°F (43°C - 49°C) after
about two to three hours of pre-warming.
The thermostat is located on the bottom of the unit near
the fan motor. Use the following directions to adjust.
Unplug the unit and allow the unit to cool completely
before handling.
1. Lock brakes on mobile units before beginning.
2. Unload the dispenser. Remove dispensers from the unit
by grasping the black plastic guide posts and lifting the
dispenser completely out of the unit. It is not necessary
to remove the steel jacket from the dispensing tube.
3. Turn the unit on its side.
4. Remove filter from bottom of unit. It is not necessary
to remove the perforated screen. The screen has access
holes in it to allow adjustment of the thermostat. The
screen is removed in the below picture to show the
location of the thermostat adjustment screw only.
Location of Thermostat Adjustment Screw
5. Use a small screw-driver to reach the adjustment screw
located under the perforated screen. Turn the screw to
the desired setting.
6. Reattach the filter before operating the unit again.
It is the responsibility of the equipment owner to
perform a personal protective equipment hazard
assessment to ensure adequate protection during
maintenance procedures.
DANGER
Failure to disconnect the power at the main power supply
disconnect could result in serious injury or death. The
power switch DOES NOT disconnect all incoming power.

hose down or flood the units with water. Do not use
power cleaning equipment, steel wool, scrapers or wire
brushes on stainless steel or painted surfaces.
Warning
n
Heated units must be allowed to cool down before
cleaning.
Caution
,
Never use an acid based cleaning solution! Many food
products have an acidic content, which can deteriorate
the finish. Be sure to clean the stainless steel surfaces of
ALL food products.
Caution
,
Maintenance and servicing work other than cleaning as

Cleaning and Sanitizing Procedures
GENERAL
You are responsible for maintaining the equipment
in accordance with the instructions in this manual.
Maintenance procedures are not covered by the warranty.
EXTERIOR & INTERIOR CLEANING
Wipe surfaces with a damp cloth rinsed in water to remove
dust and dirt from the unit. Always rub with the “grain” of
the stainless steel to avoid marring the finish. If a greasy
residue persists, use a damp cloth rinsed in a mild dish soap
and water solution. Wipe dry with a clean, soft cloth.
Never use steel wool or abrasive pads for cleaning. Never
use chlorinated, citrus based or abrasive cleaners.
Stainless steel has a clear coating that is stain resistant and
easy to clean. Products containing abrasives will damage
the coating and scratch the panels. Daily cleaning may be
followed by an application of stainless steel cleaner which
will eliminate water spotting and fingerprints. Early signs of
stainless steel breakdown are small pits and cracks. If this
has begun, clean thoroughly and start to apply stainless
steel cleaners in attempt to restore the steel.
