INSTALLATION INSTRUCTIONS
VENTING YOUR CABINET:
1. The purpose of ventilating hoods is to direct and
capture smoke, grease-laden vapors, heat, odors, or
fumes.
2. Low temperature equipment (maximum temperature
250°F/121°C) does not produce heat, odors, fumes,
grease-laden vapors or smoke and is not required to be
vented.
3. Most jurisdictions consider our low-temperature units
(maximum temperature is 350°F/177°C) as low-heat
appliances not requiring vent hoods.
4. Installation must conform with local codes. The
authority having jurisdiction of enforcement of
the codes will have the responsibility for making
interpretations of the rules.
HOW TO INSTALL CABINETS:
1. Remove all packing material from inside and outside
of cabinet.
2. Position cabinet on level oor; install the cabinet
interior (pan slides) if not already installed.
3. Plug power cord into proper wall receptacle.
UNIT SPECIFICATIONS: Unit uses six (6) elements (1325 watts each). Units are rated 8000 watts.
