INSTALLATION AND CARE

ELECTRICAL REQUIREMENTS AND GROUNDING
These numbers are found on the nameplate (serial tag) affixed to the lower back of the unit. Please record them in this booklet, in the space provided on page 13. When ordering parts and/or service, you will need to provide this information. The voltage and amperage of the unit are also stamped on the serial tag.

UNPACKING
After uncrating your cabinet, remove all tape and padding that held all doors, shelves, racks, cords, etc., in place during shipment.

ELECTRICAL REQUIREMENTS AND GROUNDING
FWE RHRB-20 models operate on 208/240 volt, 60 Hz, 3 ph, A.C. (unless ordered otherwise). If you have any questions with regard to adequate wiring or grounding in your building, a qualified electrician should be contacted before using your cabinet. The amperage of your cabinet is stamped on the name plate attached to the unit.

WARNING : ONLY A QUALIFIED ELECTRICIAN SHOULD ATTEMPT TO REPAIR OR REPLACE ELECTRICAL COMPONENTS OR WIRING.

OVEN LOCATION
The well-planned and proper placement of your oven will result in long term operator convenience and satisfactory performance.

• Proper clearance must be kept on both the left and right of the cabinet, allowing proper ventilation to the cooling fans. As the oven achieves heat, latent heat will build inside the control panel area. Cooling fans ensure that these temperatures are kept to a minimum. If proper clearance of these vents are NOT kept, heat will quickly build up. The thermal protectors will trip, shutting the unit down. Improper installation or failure to keep proper clearance will void warranty.
• Keep the oven area free and clear of all combustibles such as paper, cardboard, and flammable liquids and solvents, as these materials may ignite and become a fire/safety hazard.
• Agency regulations may require 6” clearance on the bottom and sides of the unit for cleaning. Do not place the oven on a curb base or seal to a wall. Please check with your local health code agencies to assure proper placement of your unit, as local codes may vary.
• Before making any utility connections to this oven, check the rating plate to be sure the oven specifications are compatible with the electrical services supplied for the oven. Please review all installation instructions, electrical requirements and connection to power

INSTALLATION

Installation must conform with all Local and National installation standards. Local installation codes and/or requirements may vary. If you have any questions regarding the proper installation and/or operation of your oven, please contact your local distributor. If you do not have a local distributor, please call your local FWE representative, government agency, qualified electrical contractor or Health Department to verify your local standards.

CARE AND OPERATION

CLEANING

• Keep your cabinet clean by simply wiping the interior andexterior, as needed, with a damp cloth or sponge and a mild soapy solution.

FOOD SAFETY GUIDELINES

FOOD SAFETY & COOKING
Most foods are at risk during preparation and service. As foods are thawed, cooked, held, served, cooled and reheated, they may pass several times through the temperature danger zone of 40°F to 140°F (4.4°C to 60°C). Each time food is handled, it runs the risk of cross-contamination from other food and from food-contact surfaces, such as: human hands, cutting boards, and utensils. It is recommended that passing through the 40°F to 140°F (4.4°C to 60°C) zone be done as quickly and infrequently as possible.

THE FOUR-HOUR RULE
The temperature danger zone is considered 40°F to 140°F (4.4°C to 60°C) and rapid bacteria growth zone is considered 70°F to 120°F (21°C to 49°C). Prevent potentially hazardous foods from spending more than four (4) hours combined total time in these zones. The exposure time is accumulative from time of receiving products until time it is cooked. Exposure time begins again when food is fully cooked, held, served, cooled, and reheated. FOOD

SHOULD NEVER BE REHEATED TWICE!
Food and public health dangers can be avoided with proper food handling, storage, cooking (rethermalizing) and holding methods. The key to foodborne illness prevention is constant monitoring of food temperatures (both storage and internal).

PROPER FOOD HANDLING – HACCP OVERVIEW
HACCP is a Food Safety Program that is an effective tool for safety and quality of food, from processing, receiving, storage, cooking, holding and serving. By definition, HACCP is: “HAZARD ANALYSIS CRITICAL CONTROL POINT.”

TROUBLESHOOTING CHART

Check this list first before you call for service…

• NOTE : CALIBRATION IS EXCLUDED FROM FWE WARRANTY. Thermostats on all units are calibrated at the factory  prior to shipping. Due to conditions in transit, beyond our control, occasionally units will need to be re-calibrated prior to use. This is a simple procedure for which instructions are given above. (1B, 2E)
• The heating element will either function or not function. Only a slight warmth indicates a problem with the thermostat, not the element.
