INSTALLATION INSTRUCTIONS:

VENTING YOUR OVEN:

1. The purpose of ventilation 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.

ELECTRICAL SPECIFICATIONS:

Model Nos. Volts Watts Amps Hertz Ph NEMA

CO-151-XW-UA-5B-1201 120 2000 16.6 60 1 5-20P

All models are designed for AC Service.

Model numbers may have the letters: L, M, T, or S.

HOW TO INSTALL CABINETS:

1. Remove all packing material from inside

and outside of cabinet.

2. Position cabinet on level floor; install the

cabinet interior (pan slides) if not
already installed.

3. Plug power cord into proper wall

receptacle.

4. Fill water pan with three (3) gallons of

HOT water (see CAUTION).

Undercounter Ovens FL-2291

Rev. 2 (6/05) Page 3 of 10

3. Most jurisdictions consider our low-

temperature ovens (maximum
temperature is 350°F/177°C) as low-heat
appliances not requiring vent hoods.

4. Installation must conform to local codes.

The authority having jurisdiction of
enforcement of the codes will have the
responsibility for making interpretations
of the rules.

LOW WATER LIGHT:

When water needs to be added to the pan, the
Low Water Light will stay on until the pan is
refilled.

Use of treated water is recommended for proper operation and to maintain warranty.

It will reduce scaling.
