PREPARATION

Cutout dimensions for tank units and control panels are listed on the Installation Instructions provided with the unit. Provide at least 1” clearance around the condensing unit chassis. Countertop must be flat and level before the unit is installed. After cutout is made, add stiffeners or bottom braces to counter as required to support unit weight.

IMPORTANT: Refrigeration system is air cooled. Recommend louvered grills or equivalent openings front and rear, each with a minimum size of twice the surface area of the condenser, to provide adequate air circulation.

NOTE: The condenser fan is provided with a fan guard. DO NOT remove the condenser fan guard.

Provide louvered grills and service access below control panel. Provide access to the POWER SWITCH and TEMPERATURE CONTROL UNIT located at the front of the condenser. Verify that provided sealants are applied to the underside of the top flange prior to setting the unit into the cutout. After installation, apply a thin bead of food-grade silicone sealant around the flange to seal it to the counter. Avoid storing flammable or combustible materials in, on or near the appliance. Clean the unit thoroughly after installation and before first use.

NOTE: DO NOT discard the carton or other packing materials until you have inspected the appliance for hidden damage and tested it for proper operation. Refer to SHIPPING DAMAGE CLAIM PROCEDURE on theV inside front cover of this manual.

MAINTENANCE INSTRUCTIONS

CAUTION: PERSONAL INJURY HAZARD

Disconnect appliance from electrical power before cleaning condenser coil.

CAUTION: PERSONAL INJURY HAZARD

Condenser coil fins are sharp.
Use care to avoid cuts while cleaning the condenser.

CONDENSER COIL CLEANING INSTRUCTIONS

The condenser coil must be kept clean to allow adequate air flow for proper heat dissipation. Recommend this procedure be performed monthly.

Turn POWER SWITCH OFF. Disconnect unit from electrical power.
Remove louvers or access panel to allow coil to be reached.
Using a stiff bristle brush, brush lint and debris from the condenser fins. Brush vertically, top to bottom. Collect and discard all lint and debris gathered from this operation
- IMPORTANT: The fins of the condenser coil are delicate and easily damaged. Use care to brush only in a vertical motion to avoid damaging the coil fins.
Wipe the fan blades to remove accumulated lint.
Reconnect to electrical power. Test for proper operation.

CAUTION: PERSONAL INJURY HAZARD

Disconnect appliance from electrical power before cleaning.
Wells refrigerated cold pans are constructed of high quality stainless steel. As long as the stainless steel surface is intact, the equipment will not rust or corrode.

Recommendation

A water softening device or a cartridge-type filtration device may be used to minimize lime and calcium build-up.

CARE OF STAINLESS STEEL

The surface can be damaged by mechanical abrasion, hard water deposits and chlorine:
- NEVER use steel wool, wire brushes or metal scrapers to clean the appliance. These will damage the surface.
- Hard water deposits left behind when water is evaporated will attack the surface and allow the stainless steel to rust.
- Chlorides from chlorinated cleansers, calcium / lime / rust removers (e.g. muriatic acid), even heavily chlorinated city water will attack the surface and allow the stainless steel to rust.
- DO NOT use any highly caustic cleaners. Use of highly caustic cleaners will damage the surface.
- LIMIT USE of strong caustic cleaners on warmers. Rinse thoroughly with a vinegar and water solution to neutralize any residue. Failure to do so may cause damage to the surface and allow the stainless steel to rust.
- Cleaners containing ammonia will attack the surface and allow the stainless steel to rust.
Use the proper tools in the proper way to clean your Wells cold pan.
- Soft cloth and plastic scouring pads are safe to use on stainless steel surfaces.
- Stainless steel pads may be used ONLY IF the scrubbing motion is in the direction of the visible grain. DO NOT use a circular motion.
- In the absence of visible grain, use only soft cloth or plastic pads. Scrub only in a linear motion along the longest axis of the equipment.
Use only non-chloride and non-ammonia cleansers:
- DO NOT use any cleanser listed as “chlorinated”.
- DO NOT use any cleanser listing “ammonia” or “ammonium” in its contents.
- Contact your cleaning materials supplier for suitable alkaline cleansers.
Keep your Wells cold pan clean. Clean frequently to avoid build-up of hard stubborn stains and hard-to-remove deposits.
- Rinse thoroughly with a vinegar and water solution to neutralize any residue.
- For discoloration caused by using the warmer in dry operation, use a cleaner made specifically for stainless steel.
- Wipe dry with a soft, clean, dry cloth.
- Restore the surface by using a polishing product specifically made for stainless steel after each cleaning.

OPERATING INSTRUCTIONS

IMPORTANT: DO NOT adjust the differential settings of the refrigeration system. Field adjustments of the differential settings must be made by qualified refrigeration personnel only. Unauthorized adjustment of the differential settings will void the warranty.

The temperature setting of the NSF-7 Refrigerated Cold Pan has been pre-set at the factory to meet most applications. An electronic temperature control maintains food temperature between 33ºF (.05°C) and 44ºF (6.6°C).

TEMPERATURE ADJUSTMENT

RCP-100(ST) thru RCP-600(ST)

The temperature has been preset at the factory to meet most applications.
If temperature adjustments are required, the pressure switch, located on the condensing unit, is adjustable. Temperature adjustment must be performed by a qualified refrigeration personnel only.
Normal temperature setting would be 28ºF.

RCP-7100(ST) thru RCP-7600(ST)

The LCD Display provides a readout of the sensor temperature during normal operation. Use the following to change the setpoint temperature:

To start programming, press SET key once. This will access the Fahrenheit/Celsius mode. The readout will show the current status, either F (degrees Fahrenheit) or C (degrees Celsius). Press either “up arrow” (↑) or “down arrow” (↓) to toggle between F and C designation.
Press SET again to access the setpoint. The LCD will display the current setpoint, and the S1 annunciator will blink off and on to indicate that control is in the setpoint mode. Press either “up arrow” (↑) to increase the setpoint, or “down arrow” (↓) to decrease the setpoint to the desired temperature. Factory setpoint is 21°F (-6°C).
Press the SET key again to access the differential. The LCD will display the current differential, and the DIF1 annunciator will blink off and on to indicate that control is in the differential mode.
- IMPORTANT: DO NOT adjust the differential settings of the refrigeration system. Field adjustments of the differential settings must be made by qualified refrigeration personnel only. Unauthorized adjustment of the differential settings will void the warranty.
- Press either “up arrow” (↑) to increase the differential, or “down arrow” (↓) to decrease the differential to the desired setting. Factory differential is 3ºF (.
Press the SET key again to access the Heating / Cooling mode. The LCD will display the current mode. Either “C1” for cooling or “H1” for heating. The control must be set to C1 for proper operation of the cold pan.
Press the SET key again to complete programming. Programming ends automatically if no keys are pressed for 30 seconds. Any settings that have been input to the control will be accepted at that time.
Control settings are stored in non-volatile memory. Loss of power to the unit will not require reprogramming.

IMPORTANT: DO NOT adjust the differential settings of the refrigeration system. Field adjustments of the differential settings must be made by qualified refrigeration personnel only. Unauthorized adjustment of the differential settings will void the warranty.

NOTE: The controller has both “heating” and “cooling” modes. Heating mode is not used on the RCP-series units. The control must be set to “cooling” (C1) for proper operation of the cold pan.
