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:
The power cord is 10′ long
If necessary, contact a licensed electrician to install an appropriate 20 amp electrical circuit with the correct NEMA receptacle.
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 the unit due to being connected to the wrong voltage or phase is NOT covered by warranty.
WARNING:
Risk of personal injury
The unit is not waterproof, to avoid electrical shock, keep the unit and counter from being submerged in water. Do not operate if the 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.
The 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.
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 with an electrical service according to the electrical information provided on the right.
3. Set the 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.

NORMAL OPERATION

CAUTION:
HOT SURFACE
The inner surfaces of the unit will be very hot during and after the operation.
Avoid touching the cabinet when loading or removing the product.
Operating ranges:
– air temp: 90ºF-200ºF

1. 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 power indicating light will illuminate.

2. To adjust the temperature setting, rotate the HEAT dial to the desired set point*.
   It will take approximately 30 minutes for the cabinet to preheat to your setting.  Once the cabinet reaches the temperature setting, the power indicating light will go on and off as the element cycles to maintain the cabinet temperature setting.

3. Load cabinet with pans or trays.

4. When removing items, start at the bottom and work up to the top. This keeps food hotter and eliminates spillage onto lower items.

*For food safety reasons, it is recommended that the holding temperature be set at 140°F or higher.

**FOOD HOLDING GUIDE

**

CAUTION: SAFE FOOD HOLDING PRACTICES RECOMMENDED Cooking food to a safe temperature, holding at a temperature of at least 140°F is critical in the prevention of foodborne illness. Hold only cooked, hot food at 140°F or higher. This cabinet is not intended to cook or reheat food. Food must be at the appropriate temperature before being placed in a cabinet.
NOTE: Times and temperatures observed in a test kitchen environment. Times and temperatures may vary, depending on the initial food quality, initial cooking temperature, and user expectations of acceptable food quality.

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 the appliance to cool before cleaning.
IMPORTANT:
DO NOT spill or pour
water into controls, control panels, or wiring. Water damage is not covered by a warranty.
CAUTION:
Beware of sharp edges with sheet metal during the 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. Remove the side heat duct and rack assemblies. Clean the inside of the unit as well as the removed parts. Reinstall when all parts are dry and clean.
4. 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.
5. The plastic control panel should be washed with a clean damp cloth and chlorine-free detergent. Rinse thoroughly with a clean damp cloth and allow to dry. Do not use abrasive cleaners, waxes, car polish, or substances containing strong aromatic solvents or alcohol.

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.

RECOMMENDED TIPS FOR CLEANING STAINLESS STEEL

Purpose| Frequency| Cleaning Agent| Method of Application
Routine cleaning| Daily| Soap. ammonia detergent and water|  Sponge with a cloth, rinse with clear water and wipe dry.
Smears/ Fingerprints| As needed| Stainless steel cleaner or similar products| Rub with a soft cloth as directed on the package. Rub in direction of the grain of stainless steel. Do not use vinyl trim.
Stubborn spots and stains| Daily as needed| Any chloride-free or
phosphate-free
cleaner| Apply with a damp sponge or cloth. Rub in direction of the grain of stainless steel. Rinse thoroughly, especially if cleaner contains chlorine bleach, do not use on vinyl trim.
Hard water spots| Daily as needed| Vinegar| Swab with a cloth.
Rinse with water and wipe dry.

CABINET MAINTENANCE

WARNING:
DO NOT perform these procedures while the cabinet is turned on or heated. Turn off the power and wait for the cabinet to cool to room temperature.
CAUTION:
Do not move the cabinet unless the door is securely closed. Serious damage to hinges and doors may result if bumped into tables, walls, or other equipment when the doors are open.
CASTERS
Caster bearings may be equipped with Zerk grease fittings so that they may be easily lubricated with a grease gun. Lubricate bearings at least once every six months.
REPLACING THE DOOR GASKET

1. Remove the screws located under the gasket on the cabinet.
2. Remove the gasket and discard.
3. Install the new gasket and replace the screws.

REVERSING THE DOOR
Reversing the door takes about 30 minutes & requires two people.

1. Using a small screwdriver, pry off the hinge covers and set them aside. Removing the covers will allow access to the inside hinge screws. Remove the three screws that hold each hinge to the cabinet. DO NOT REMOVE THE SCREWS THAT HOLD THE HINGES TO THE DOOR. Remove the door, taking care not to let it fall.
2. Remove the door strike plate and screws adjacent to the door opening on the cabinet. Reinstall the door strike plate and screws on the opposite sides of the cabinet.
3. Screw hinges onto the opposite sides of the door.
4. With the help of another person, hold the door up to the cabinet and attach it with the screws removed in step one. Before tightening the screws, be sure the door is flush, level and square. Replace the hinge covers.
