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 assure that these temperatures are kept to a minimal.
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.

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).
FOOD SAFETY
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:
“ H AZARD A NALYSIS C RITICAL C ONTROL P OINT.”

* * 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)
* Heating element will either function or not function. Only a slight warmth indicates a problem with the thermostat,
* not the element.
