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. Welbilt 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.

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.
Refrigeration
Model
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.
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.
Part Number: 9294900 12/19

Freezer Control Panel With Optional Power Switch
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 15.
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).

maintain box temperature at the control setting. For
more information see R290 Evaporator Fan Operation
on page 15.
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).
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).

R290 Energy Saver Switch
Select freezers are equipped with an energy saver switch
for service use. It is a rocker switch located behind the
mechanical raceway. It controls the length of time that heat
is applied to the door perimeter. The normal operating
position for this switch is the on position, providing the
shortest amount of time. If excessive condensation is
observed on the door opening, switch to the off position
with the help of an authorized service agent. The off
position will increase the length of time the door heater is
on.
R290 Temperature Alarm
The alarm will sound and 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
mid-range 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 (-19ºC)
box temperature. The high freezer temperature point is 20°F
(-7°C). Freezers do not have a low temperature point.
R290 EVAPORATOR FAN OPERATION
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult

INTERIOR CLEANING
EXTERIOR CLEANING
Notic
Notic
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.
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.
Notic
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.
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.
18
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.
Part Number: 9294900 12/19
Section 4
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.
Maintenance
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.
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.
CASTERS
Wipe casters with a damp cloth monthly to prevent
corrosion.
