OPERATION NOTES

1. Never place food directly in cold pans. Always use insets or food

pans.

2. Use only pre-chilled products. Stir product occasionally to maintain

chilled temperatures and prevent bottom freezing.

3. Use perforated bottom strainer plates when operating units with

ice. Perforated bottom strainer plates are optional and must be

ordered separately.

4. Models RCP-7100 thru RCP-7600 are performance tested to

NSF-7 for use with potentially hazardous foods when the pan rails

are installed on the lower pan rail supports.

5. Periodically clean condensing coils to remove accumulated dust

and debris. Failure to clean coils will decrease performance and

may void the warranty.

See CONDENSER CLEANING, page 8.

DAILY START-UP

1. Turn POWER SWITCH (located on condensing unit) ON. Allow

unit to run for approximately 30 minutes to reach operating

temperature.

provided with the unit are designed to hold 12" x 20" food pans up

to 6" deep.

For NSF-7 operation, use 12" x 20" x 4" deep pans on the lower

pan rail supports.

3. Install appropriate food pans or insets. Place pre-chilled product in

food pans. Unit will maintain pre-chilled product at 33 - 41ºF.

MAINTENANCE INSTRUCTIONS

CARE OF STAINLESS STEEL

1. The surface can be damaged by mechanical abrasion, hard water

deposits and chlorine:

a. NEVER use steel wool, wire brushes or metal scrapers to clean

the appliance. These will damage the surface.

b. Hard water deposits left behind when water is evaporated will

attack the surface and allow the stainless steel to rust.

c. 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.

d. DO NOT use any highly caustic cleaners. Use of highly caustic

cleaners will damage the surface.

a. 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.

e. Cleansers containing ammonia will attack the surface and allow

the stainless steel to rust.

2. Use the proper tools in the proper way to clean your Wells cold pan:

a. Soft cloth and plastic scouring pads are safe to use on stainless

steel surfaces.

b. 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.

c. 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.

4. Use only non-chloride and non-ammonia cleansers:

a. DO NOT use any cleanser listed as “chlorinated”.

b. DO NOT use any cleanser listing “ammonia” or “ammonium” in

its contents.

c. Contact your cleaning materials supplier for suitable alkaline

cleansers.

5. Keep your Wells cold pan clean. Clean frequently to avoid build-up

of hard, stubborn stains and hard-to-remove deposits:

a. Rinse thoroughly with a vinegar and water solution to neutralize

any residue.

b. For discoloration caused by using the warmer in dry operation,

use a cleaner made specifically for stainless steel.

c. Wipe dry with a soft, clean, dry cloth.

d. Restore the surface by using a polishing product specifically

made for stainless steel after each cleaning.

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.

MAINTENANCE INSTRUCTIONS (continued)

TEMPERATURE ADJUSTMENT

RCP-100 thru RCP-600

1. The temperature has been preset at the factory to meet most

applications.

2. 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.

3. Normal temperature setting would be 28ºF.

RCP-7100 thru RCP-7600

The LCD Display provides a readout of the sensor temperature

during normal operation. Use the following to change the setpoint

temperature:

1. 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" (Ï) or "down arrow" (Ð) to toggle between

Fand Cdesignation.

2. 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" (Ï) to increase the setpoint, or "down

arrow" (Ð) to decrease the setpoint to the desired temperature.

Factory setpoint is 21ºF.

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 and 44ºF.

MAINTENANCE INSTRUCTIONS (continued)

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.

3. 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" (Ï) to increase the differential, or "down

arrow" (Ð) to decrease the differential to the desired setting.

Factory differential is 3ºF.

4. 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.

5. 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.

6. Control settings are stored in non-volatile memory. Loss of power

to the unit will not require reprogramming.
