INSTALLATION and STARTUP

WARNING:
Risk of personal injury

Installation procedures must be performed by a qualified technician with full knowledge of all applicable electrical codes. Failure could result in personal injury and property damage.

IMPORTANT:
Power cord is 10′ long.
If necessary, contact a licensed electrician to install an appropriate electrical circuit with correct NEMA receptacle. See serial tag on cabinet for electrical requirements.
DO NOT use an extension cord.

CAUTION:
Electrical Shock Hazard

The ground prong of the power cord is part of a system designed to protect you from electric shock in the event of internal damage.

DO NOT cut off the large round ground prong or twist a blade to fit an existing receptacle.

IMPORTANT:
Not under warranty

Damage to unit due to being connected to the wrong voltage or phase is NOT covered by warranty.

WARNING:
Risk of personal injury

Unit is not waterproof, to avoid electrical shock, keep unit and counter from being submerged in water. Do not operate if unit has been in contact with water.

LOCATION

For proper operation and maximum performance, locate the unit in an ambient air temperature of 70ºF (21ºC).

Avoid placement in areas near exhaust fans or where there are active air movements.

For safe operation and maximum performance, locate the unit at least 2” from any wall or combustible material. Do not crimp power cord.

Unit must be on a solid level surface.

GROUNDING INSTRUCTIONS

This appliance is equipped with a cord having a grounding wire with a grounding plug which must be plugged into an outlet that is properly installed and grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.

WARNING—Improper use of the grounding can result in a risk of electric shock. Consult a qualified electrician or service agent if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.

To prevent an electrical shock hazard between the appliance and other appliances or metal parts in close vicinity, an equalization-bonding stud is provided. An equalization bonding lead must be connected to this stud and the other appliances/metal parts to provide sufficient protection against potential difference. The terminal is marked with the following symbol:

ELECTRICAL INFORMATION

INITIAL START-UP

1. Prior to use, thoroughly clean the interior of the unit, per the instructions in this manual.
2. Plug the power cord of the cabinet into a grounded outlet according to the voltage and amperage specified on the serial tag on the heating module. This can be located on the top right rear corner of the heating unit.
3. Set POWER switch to the “ON” position.
4. Do not load product into the cabinet. Allow the heat to remove any residual oils which may adhere to inside metal surfaces. A slight emission of smoke is common during the first few hours of operation.

Control panel layout

NORMAL OPERATION

Factory default setpoints:

• cook: 325ºF
• hold: 200ºF
• timer: 1 hour

Operating ranges:

• cook temp: 100ºF-325ºF
• hold temp: 100ºF-200ºF
• timer:10 min. -18 hours

FIRST USE

Turn the cabinet on using the power switch located on the far left side of the control panel. Once the switch is turned on, the control display will illuminate.

When the cabinet is first turned on, the time display will show the current hardware / software revision, for example “F107”. Then the display will display the factory default settings.

PROGRAMMING THE CONTROLLER

1. Make sure the unit is turned “ON”.
2. To set COOK temperature, push “COOK TEMP” knob in and rotate clockwise to increase temperature or counter-clockwise to decrease temperature.
3. To set COOK time, push “COOK TIME” knob in and rotate clockwise to increase time or rotate counter-clockwise to decrease cook time. NOTE: For cook times of 10 minutes to two hours, timer will increase/decrease in 5 minute increments. For cook times over 2 hours, timer will increase/decrease in increments of 15 minutes. Note: setting the cook time is only necessary if not using the meat probe.
4. To set HOLD temperature, push “HOLD TEMP” knob in and rotate clockwise to increase temperature or counter-clockwise to decrease temperature.

TO CHANGE TEMPERATURE SCALE

The controller can be changed from °F to °C and vice versa. In order to toggle between the Fahrenheit and Celsius scales:

1. Make sure the unit is turned “OFF”
2. Push and hold the “START/CANCEL” button
3. While pushing the “START/CANCEL” button, turn “ON” the main power switch. An audible beep will be heard and the center display “deg F” or “deg C”
4. Repeat procedure to toggle between °F and °C

If the temperature in the control compartment exceeds safe operating limits, an audible alarm will sound and the TIME display will scroll “CALL CUSt SErV”. Should this condition occur, turn off and unplug the cabinet and then call for service. Prolonged operation of the cabinet in this condition WILL result in electrical component failures.

COOKING BY TIME

CABINET OPERATION

1. Turn power switch “ON”. Unit will heat to “HOLD” setting and will
   stay in “HOLD” mode until cook cycle is started. “HOLD” LED light adjacent to the timer display will illuminate.

2. Program desired settings according the controller programming instructions.

3. Load product into cabinet.

4. Press and release the “START/CANCEL” button to begin COOK cycle. The colon in the TIME display will flash and the LED lights adjacent to the TIME display will switch from “HOLD” to “COOK”.
   The colon will continue to flash as long as the timer is active.

5. Timer will count down by one minute increments for the entire COOK cycle.

6. Upon completion of the COOK cycle and audible alert will sound
   and the cabinet will automatically switch to the HOLD mode. The LED light adjacent to the TIME display will switch from “COOK” to “HOLD”.

7. The TIME display will now count up until the cycle is canceled.

8. Cycle can be canceled by:

   • Push and hold the “START/CANCEL” button until audible alarm sounds (about 5 seconds)
   • Turn master switch to “OFF”.
     

NOTE: Settings for the cook and hold cycle will be saved in the controller for the next cook cycle. Refer to programming instructions to change the settings.

NOTE: To protect electrical components, the cooling fans inside the heating unit will operate whenever the interior temperature of the heater rises above 120°F. They will operate, even if the master ON/OFF switch is turned to ‘OFF.” Do not unplug cabinet unless cooling fans have turned off.

If the temperature in the control compartment exceeds safe operating limits, an audible alarm will sound and the TIME display will scroll “CALL CUSt SErV”. Should this  condition occur, turn off and unplug the cabinet and then call for service. Prolonged operation of the cabinet in this condition WILL result in electrical component failures.

DAILY CLEANING PROCEDURES

CAUTION:
ELECTRIC SHOCK HAZARD
Disconnect appliance from electric power before cleaning.

CAUTION:
HOT SURFACE
Exposed surfaces can be hot to the touch and may cause burns. Allow appliance to cool before cleaning.

IMPORTANT:
DO NOT spill or pour water into controls, control panel or wiring. Water damage is not covered by warranty.

CAUTION:
Cabinet may generate steam, use caution when opening doors to clean unit.

CAUTION:
Beware of sharp edges with sheet metal during cleaning process.

1. After all food products have been removed from the cabinet, turn the power switch to “OFF” and allow the cabinet to cool.
2. Unplug the unit prior to any cleaning.
3. Racks may be removed for cleaning. Lift up and pull out. Hand wash with chloride/phosphate-free soap or detergent. DO NOT exceed recommended concentrations or mixing rations. Never use abrasive cleaners, waxes, car polish, or substances containing strong aromatic solvents or alcohol.
4. Clean the inside of the unit as well as the removed parts. Rinse racks and cabinet interior with clear water. Wipe off any standing liquid or residue from all surfaces, corners, or near edges and allow to dry. Reinstall when all parts are dry and clean.
5. Inspect and clean the areas where there are vents or filters, making sure no water gets into the internal controls or electrical areas of the cabinet.

CAUTION:
Cleansers, detergents, degreasers, sanitizers, or bleaching agents that contain chlorides or phosphates will cause permanent damage to stainless steel products. The damage appears as pits, eruptions, voids, small holes, severe discoloration or dulling of the metal finish.

Water with high chloride content can also damage stainless steel. If unsure of your water quality, we recommend you have it tested. THIS DAMAGE IS PERMANENT, COSTLY TO REPAIR, AND IS NOT COVERED BY THE WARRANTY.
