Installation Section 2

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.

Installation Section 2

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.

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.

Caution

,

All single-section units require that the swivel casters be
mounted on the front and rigid casters be mounted on
the rear.

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).

Warning

n

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.

Caution

,

Do not throw items into the storage area. Failure to
heed this recommendation could result in damage to
the interior of the cabinet or to the blower coil.

Operation Section 3

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).

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.

24 Part Number: 9294839 03/17

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.
