Electrical Service
DANGER
Check all wiring connections, including factory
terminals, before operation. Connections can become
loose during shipment and installation.
nWarning
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.

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.
nWarning
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.
nWarning
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.
,Caution
All single-section units require that the swivel casters be
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

R290 Controls/Programming/Settings
R290 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 go into
defrost mode.
2. 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 35 minutes to complete.
3. The display will continue to read dEF for an additional
30 minutes while the cooling cycle cools the box to the
set temperature.
4. Then the digital 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. For
more information see R290 Evaporator Fan Operation
on page 21.
R290 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 30 minutes).

R290 Freezer
Freezers are factory set at mid-range to maintain about -2ºF
(-19ºC) box temperature.
1. At initial start-up or anytime power is disconnected,
then reconnected to the unit, the control will go into
defrost mode
2. 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 35 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. For
more information see R290 Evaporator Fan Operation
on page 21.
R290 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 seven hours since the last defrost cycle
OR if evaporator coil temperature drops below -30ºF (-34ºC)
(indicating excessive frost on the coil).
R290 Freezer Manual Defrost
If a manual defrost is desired, hold the upper left button for
five seconds or 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 six minutes
and a MAXIMUM of 35 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 until the evaporator reaches
-5°F (-21°C) or two 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).
