Electrical Service

DANGER

Check all wiring connections, including factory terminals, before operation. Connections can become loose during shipment and installation.
Units with two power cords must be plugged into individual branch circuits. During movement, cleaning or repair it is necessary to unplug both power cords.

Warning

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.
Plug units with R290 refrigerant into a receptacle that is a minimum of 14” (36cm) above the floor.
All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes.
The equipment must be grounded.
A separate fuse/circuit breaker must be provided for each unit.
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. 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.

RATED AMPERAGES, HORSEPOWER, VOLTAGE & POWER CORD CHART

Units with plugs are supplied with approximately 6ft (183cm) cords.
Models 406P and 407P may be stacked using a stacking collar. In this case two 6ft (183cm) long grounded supply cords and plugs are standard.

Error Codes

LED Flashes : This means there is a function that is being delayed by a timer/external signal or disabled by another process that is already going on. For example, the compressor icon will flash if the cabinet temperature is above the cut-in temperature, but the control hasn’t met the minimum compressor off-time.
E0: Air probe error
E1: Coil probe error
LO: Low-temperature alarm (-20°F for 90 minutes)
HI: High-temperature alarm (+20°F for 90 minutes)
Ef: Unit operating on parameter error
Ed: Defrost ended on timeout rather than by temperature

Controls/Programming/Settings

R290 REFRIGERATORS

The control will initiate a defrost at start up. This defrost will continue up to 41°F or a minimum runtime of 1 minute/ maximum runtime of 75 minutes. The evaporator fans will run continually during the operation of the unit. There will be no drip time after the defrost. The compressor powers on immediately after reaching defrost termination temp.
When the control calls for cooling, a minimum compressor on time is 2 minutes. Condensing unit/evaporator fans power on and the normal cooling cycle continues.
Defrost will initiate after 6 hours of actual time (note: this is not running time). Display freezes the last cabinet temp recorded until defrost is completed and the cabinet reaches set point again.

FREEZERS

Plug the unit in to begin operation. At initial start-up or anytime power is disconnected, then reconnected to the unit, the control will start the unit in defrost.
The unit can be turned on and off by pressing the on/off button on control. The unit will begin in a defrost cycle if it is turned on at the control.
After initializing, the control will immediately enter a DEFROST mode. The compressor and condenser fan as well as the evaporator fan will remain off until initial defrost
is complete. This initial defrost cycle may take up to 15 minutes to complete, then the freezing cycle will begin.
After initializing and the defrost cycle, the electronic temperature control will cycle the compressor, evaporator fan motor, and condenser fan motor to maintain box temperature at the control setting.
With the doors closed, the temperature of the cabinet should reach 0°F (-18°C) on freezers in about one hour after the freezing cycle begins. The electronic temperature control constantly monitors box temperature as well as evaporator coil temperature to maintain consistent product temperatures. As an added energy-saving feature, the electronic controller will switch the evaporator fan motor on and off with the compressor and condenser fan motor.
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.

Electronic Temperature Control Location & Adjustment

The control is located in the control box at the rear of the unit. It is factory set at mid-range to maintain about -3°F (-18°C) box temperature. To adjust for colder temperatures, press and hold the set button until the current set point appears and is blinking on the screen. Press the down arrow to adjust to the desired temperature.
Press the set button to save the temperature.
To adjust for warmer temperatures, press and hold the set button until the current set point appears and is blinking on the screen. Press the up arrow to adjust to the desired temperature. Press the set button to save the temperature

Freezer Automatic Defrost

The control is set to defrost every 5 hours. The maximum defrost duration is 35 minutes.

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.
The unit can also be put into a manual defrost by pressing and holding the snowflake button on the control.
When the control enters the defrost mode, whether manual or automatic, it switches on the compressor and condenser fan motor, and energizes the hot gas solenoid to warm the evaporator coil and melt all frost accumulated during the previous refrigeration cycle. The control will continue the defrost cycle for 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 for two minutes AFTER
the compressor and condenser fan motor has begun operating.

Maintenance

DANGER

It is the responsibility of the equipment owner to perform a Personal Protective Equipment Hazard Assessment to ensure adequate protection during maintenance procedures.
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.
Disconnect electric power at the main power disconnect for all equipment being serviced. Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic operation.

Warning

Never use sharp objects or tools to remove ice or frost. Do not use mechanical devices or other means to accelerate the defrosting process.
When using cleaning fluids or chemicals, rubber gloves and eye protection (and/or face shield) must be worn.
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 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.
Maintenance and servicing work other than cleaning as described in this manual must be done by an authorized service personnel.
Over shelves and other items mounted to the top of the counters should never be installed in the field due to the potential damage to the refrigeration system.

Responsibility

You are responsible for maintaining the equipment in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty.

Interior Cleaning

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.

Exterior Cleaning

Caution

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.
Wipe casters with a damp cloth monthly to prevent corrosion.

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.

Door Adjustment

If the door needs lowering at the handle, use a 5/16” (8mm) wrench to loosen the hinge screws and install a spacer outside of the hinge. Tighten the screws.
If the door needs to be higher at the handle, use a 5/16” (8mm) wrench to loosen the hinge screws and install a spacer inside of the hinge. Tighten the screws.
