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
HOW TO CHANGE FROM °F TO °C (if needed)
1. Push the switch on; the light will come on.
2. Push and hold the “SET” button and the button in the
lower left hand corner together for 5 seconds.
You have now entered into the menu.
3. Scroll over the”Unit” and change it to “C” , then scroll
to the “END”.
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 different 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.
For use with the Roast-N-Hold Control:
1. On the Retherm control, when selecting the COOK
temperature, the humidity setpoint will be ashing on
the Aquatemp control.
2. Turn the knob on the humidity control to the desired
“Cook Humidity” value.
3. On the Roast-N-Hold control, when selecting the
HOLD temperature setpoint, the humidity setpoint
will be ashing on the Aquatemp control.
4. Turn the knob on the humidity control to the desired
“Hold Humidity” 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.
How to use the Automatic Water Fill:
There is a water ll connection under the bottom left rear
of the oven. Remove the plug on the end of the connector.
1. Connect the plastic tubing provided to the connector
and the other end to your water supply. Turn water
supply on.
2. Press and hold both the DISPLAY button and the knob
of the AquaTemp humidity control for ve seconds.
3. Turn the knob until when the display shows FILL,
select “Y” for yes and press the knob to set.
4. Go to END to exit the menu. Auto water ll should
start.
To shut down:
1. Press and hold both the DISPLAY button and the knob
of the Aquatemp humidity control.
2. Turn the knob to FILL and push to enter. Select “N”
for no; go to END to exit the menu.
3. Turn off your water supply and clean out the water pan
after it cools (See “Maintenance Instructions” on page
8).
NOTES: It is recommended to use treated water to
prevent failure of ll valve.
If water supply pressure is high, it is recommended to
regulate it to make sure the ll valve closes reliably.
