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.
• Check all green ground screws, cables and wire
connections to verify they are tight before start-up.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for each
unit.
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.

Section 2 Installation
Leveling
After the cabinet has been placed in the desired location,
cabinets with legs must be leveled. Level units from front to
back and from side to side. Leveling will insure proper door
operation and removal of condensate. Cabinets with casters
must have the caster brake set so the cabinet cannot move.
Stabilizing
It is very important that all legs are properly adjusted to
keep the cabinet level, evenly distribute the weight and to
make sure the unit will not rock, lean or be unstable.
Leg & Caster Installation
DANGER
Legs or casters must be installed and the legs or casters
must be screwed in completely to prevent bending.
When casters are installed the mass of this unit will
allow it to move uncontrolled on an inclined surface.
These units must be tethered/secured to comply with
all applicable codes.
Warning
n
The unit must be installed in a stable condition with
the front wheels locked. Locking the front casters after
installation is the owner’s and operator’s responsibility.

mounted on the front and rigid casters be mounted on
the rear.
To install the legs or casters:
1. Remove unit from skid.
NOTE: The bolts used to hold the unit to the skid should
be re-used as the fourth hex head bolt for each caster
or leg plate installation. The bolt should not measure
over 2” (5cm) in length.
2. Raise unit to access leg/caster mounting holes on
bottom of unit.
3. Attach the legs or casters to bottom of cabinet using
hex head bolts.
Warning
n
Use a jack to lift the refrigeration unit off the ground
just far enough to remove the leg/caster. Place blocking
underneath the unit. Do not work underneath a raised
unit without proper blocking. Do not lift the unit more
than necessary to remove the leg/caster. Lifting the unit
too far can make the unit unstable.

Operation Section 3
Controls/Programming/Settings
Refrigerator
Refrigerators are factory set at mid-range to maintain about
38ºF (3ºC) box temperature.
1. At initial start-up or anytime power is disconnected,
then reconnected to the unit, the control will delay all
operations for a short time (up to 10 minutes.)
2. Then the digital thermostat will display box
temperature.
3. The temperature control will cycle the compressor,
evaporator fan motor and condenser fan motor to
maintain box temperature at the control setting. See
evaporator fan matrix for more information.
Refrigerator Defrost
The temperature control also monitors the evaporator
temperature and will turn off the compressor and
condenser fan motor when needed to allow accumulated
frost on the evaporator to clear. During this defrost cycle,
the digital temperature display will read dEF. After the
defrost cycle is complete, the temperature control will
return to a normal cooling cycle, but the display will
continue to read dEF until the evaporator returns to normal
cooling temperatures (up to 15 minutes).
Freezer
Freezers are factory set at mid-range to maintain about -3ºF
(-19ºC) box temperature.
1. At initial start-up or anytime power is disconnected,
then reconnected to the unit, the control will delay all
operations for a short time (up to 10 minutes.)
2. Then the control will enter a DEFROST mode and the
display will read dEF. The compressor and condenser
fan as well as the evaporator fan will remain off until
this initial defrost is complete. This initial defrost cycle
may take up to 15 minutes to complete.
3. The display will continue to read dEF for an additional
30 minutes while the freezing cycle cools the box to the
set temperature.
4. Then the thermostat will display box temperature.
5. The temperature control will cycle the compressor,
evaporator fan motor and condenser fan motor to
maintain box temperature at the control setting. See
evaporator fan matrix for more information.
Freezer Automatic Defrost
The control also monitors compressor total running time
and will enter a defrost cycle after total compressor running
time is greater than 4-hours since the last defrost cycle OR
if evaporator coil temperature drops below -30ºF (-34ºC)
(indicating excessive frost on the coil.)
Freezer Manual Defrost
If a manual defrost is desired, simply unplug the unit for
several seconds, then plug unit back in. This will cause the
control to re-initialize and then enter a defrost cycle.
When the control enters the defrost mode, it switches off
the evaporator fan motor, compressor and condenser fan
motor, and switches on the defrost heater to warm the
evaporator coil. Thereby melting all frost accumulated
during the previous refrigeration cycle. The digital
temperature display will now read dEF. The control will
continue the defrost cycle for a MINIMUM of 8 minutes and
a MAXIMUM of 30 minutes depending on the amount of
frost accumulated on the evaporator coil.
After the defrost cycle is complete, the control returns
to a normal refrigeration cycle, however the evaporator
fan motor will not switch on for 2 minutes AFTER the
compressor and condenser fan motor have begun
operating. The digital temperature display will continue
to read dEF until the evaporator has returned to normal
freezing temperatures (up to 30 minutes).

ENERGY
SAVING
Thermostat Dial
The temperature control is located behind the louvered
panel and has a knob. The knob, Colder 1-9, has no function.
Turning this knob does not change the temperature of the
unit, the programmed temperature nor can it be used to
shut the unit off. The digital remote temperature display is
used to control the temperature in the unit.
Power Switch
Select units are equipped with a power disconnect switch
located behind the louvered panel. Switch must be in the
on position for the unit to operate. On freezers, if the switch
is turned off, then returned to the on position, the unit will
enter a defrost cycle and the display will read dEF.
Energy Saver Switch
Select units are equipped with an energy saver switch.
It is a rocker switch located behind the louvered panel
that controls the amount of heat applied to the door
perimeter. The normal operating position for this switch
is the on position (red portion of the rocker switch will be
visible), providing the least heat. If excessive condensation
is observed on the door opening, press the energy saver
switch to the off position, to increase the amount of heat.
Temperature Alarm
The alarm will flash “HI” or “LO” 90 minutes after the unit
has reached its alarm temperature point or after any
power interruption if the temperature is above or below
the alarm set points. Refrigerators are factory set at midrange to maintain about 38ºF (3ºC) box temperature. The
high refrigerator temperature point is 50°F (10°C). The low
refrigerator temperature point is 25°F (-4°C). Freezers are
factory set at mid-range to maintain about 3ºF (-18ºC) box
temperature. The high freezer temperature point is 20°F
(-7°C). Freezers do not have a low temperature point.
Service Alert
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult the
service manual or contact Technical Support at
1-844-724-CARE if you are unsure of the proper function.

Maintenance Section 4
INTERIOR CLEANING
Notice
When cleaning interior and exterior of unit, care should
be taken to avoid the front power switch and the rear
power cord. Keep water and/or cleaning solutions away
from these parts.
Notice
Never use a high-pressure water jet for cleaning or hose
down or flood interior or exterior of units with water. Do
not use power cleaning equipment, steel wool, scrapers
or wire brushes on stainless steel or painted surfaces.
The interior can be cleaned using soap and warm water. If
this isn’t sufficient, try ammonia and water or a nonabrasive
liquid cleaner.
EXTERIOR CLEANING
Notice
Never use an acid based cleaning solution on exterior
panels! Many food products have an acidic content,
which can deteriorate the finish. Be sure to clean the
stainless steel surfaces of ALL food products.
Clean the area around the unit as often as necessary to
maintain cleanliness and efficient operation.
Wipe gasket and surfaces with a damp cloth rinsed in water
to remove dust and dirt from the outside of 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 exterior panels have 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.

Section 4 Maintenance
DRAIN
Each unit has a drain located inside the unit that removes
the condensation from the evaporator coil and routes it
to an external condensate evaporator pan. Each drain can
become loose or disconnected during normal use. If you
notice water accumulation on the inside of the unit, be sure
the drain tube is connected to the evaporator drain pan.
If water is collecting underneath the unit, make sure the
end of the drain tube is in the condensate evaporator. The
leveling of the unit is important as the units are designed to
drain properly when level. Be sure all drain lines are free of
obstructions.
CLEANING THE CONDENSER COIL
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 monthly. If
conditions are such that the condenser is totally blocked
in a month, 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.
Failure to maintain a clean condenser coil can initially cause
high temperatures and excessive run times. Continuous
operation with a dirty or clogged condenser coil can
result in compressor failure. Neglecting the condenser coil
cleaning procedures will void any warranties associated
with the compressor and cost to replace the compressor.
DOORS/HINGES
Over time and with heavy-use doors, the hinges may
become loose. If this happens, tighten the screws that
mount the hinge brackets to the frame of the unit. Loose
or sagging doors can cause the hinges to pull out of the
frame, which may damage both the doors and the hinges.
In some cases this may require qualified service agents or
maintenance personnel to perform repairs.
PREVENTING BLOWER COIL CORROSION
To help prevent corrosion of the blower coil, store all acidic
items, such as pickles and tomatoes, in seal-able containers.
Immediately wipe up all spills.
CASTERS
Wipe casters with a damp cloth monthly to prevent
corrosion.
