INSTALLATION INSTRUCTIONS
VENTING YOUR OVEN:
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 ovens
(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.
Use of treated water is recommended for
proper operation and to maintain warranty.
It will reduce scaling.
CAUTION
UNIT SPECIFICATIONS: All units use three (3) elements (2670 watts each).
All units are rated 8000 watts. Water units have one (1) immersion element (1850 watts).

HOW TO USE THE AQUATEMP HUMIDTY CONTROL:
* The units of the humidity control are approximate % relative humidity.
The amount of moisture will vary for the same %RH value at dierent
oven temperatures.
* The LOW WATER Light comes on when water pan needs to be relled.
* Press the ON/OFF button to turn it on.
Setting the Humidity:
1. At any time, press the knob and the setpoint %RH will ash.
2. Turn the knob to the value you desire.
3. Press the knob to set the value.
NOTE: These humidity values then are set and switch automatically based
upon which Roast-N-Hold mode it is in.
The DISPLAY BUTTON momentarily shows the approximate relative
humidity in the oven. When water level is low, %RH is not correct, so no
value is displayed and the water heater does not heat.
NOTES:
It is recommended to use treated water to prevent failure of ll valve.
LOW WATER LIGHT:
MANUAL FILL: When water needs to be added to the pan, the Low Water
Light will stay on and the humidity will not work until the pan is relled.
AUTO FILL: If water level is low and water supply is not connected, an
error code will display after a time limit.
