panel/body side section.  
Installation of the wiring must be made in accordance  
with local codes, and the National Electrical Code,  
ASNI/NFPA 70-1990, or in Canada, the Canadian  
Electrical Code in regards to:  
Electrical Connection  
Before attempting the electrical connection, the rating  
plate should be checked to confirm that the oven’s  
electrical characteristics and the electrical supply are  
compatible. e plate is located on the inside surface of  
the control panel/body side.  
1. Switch panel size

5. Temperature limitations of wires  
6. Method of connection, (conduit, cable, etc.)  
• Attach the appropriate plug to the end of the cord  
supplied with the oven.

It is recommended that your supply water not exceed  
any of the following parameters: 60 PPM total dissolved  
solids; 20 ppm alkalinity; 13 ppm silica; 30 ppm chloride;  
PH factor of 7.5.  
Consult a local water treatment specialist for  
recommendations regarding your water supply system  
and its use with this oven. e use of highly mineralized,  
(‘hard’), water could negatively affect the quality of  
products prepared using the oven. e potability of  
supply water does not guarantee its suitability for use  
with the moisture+.  
Water supply connection to the moisture+ is made via  
a 1/4” NPTF fitting at the rear of the oven. e ability  
to move the oven for service and cleaning may be a  
consideration when choosing the type of connection  
and supply line to be attached at this fitting.  
e moisture+ water delivery system includes a water  
pressure regulator that has been pre-set to operate at 10  
psi. e water supply must maintain at least 20 psi and a  
flow rate of three gallons per minute for proper operation  
of the oven’s moisture injection system.  
Drain  
Your moisture+ oven has a gravity drain in the left rear  
corner of the oven cavity. e drain pipe that exits the  
rear of the oven must be directed downward toward the  
floor, and should run directly to an open floor drain.  
Avoid using flexible hose that could sag or kink, allowing

2. Press and hold the programming  
button (bottom right button), until the  
controller display reads “enter code”.  
• If the actual temperature inside the oven exceeds  
the set temperature by 50°F, the display will show  
“HI TEMP” and the alarm will sound. e fan will  
continue to run, however, power to the heaters will  
be cut.  
3. Insert the CARD into the reader with

CLEANING AND MAINTENANCE  
1. e oven should be allowed to cool sufficiently  
Check Calibration  
before beginning the cleaning procedure.  
Tools: Digital thermometer with probe; oven mitt.  
See also, Temperature Calibration on page 12.  
2. Wipe exposed cleanable surfaces when cool with  
a mild detergent and hot water. Stubborn residue  
spots may be removed with a lightweight non-  
metallic scouring pad. Dry thoroughly with a clean  
cloth.  
1. Clamp the probe in the center of the middle rack.  
2. Pass the probe wire out of the oven between the  
door and the door seal and close the door.  
3. Painted surfaces should be cleaned using a mild  
soap and warm water solution on a sponge or soft  
cloth. Dry thoroughly.  
3. Plug the probe wire into the thermometer.  
4. Press the oven On/Off button.  
4. Stainless Steel surfaces may also be cleaned using a  
mild soap and warm water solution on a sponge or  
soft cloth. Stubborn stains may be removed using a  
non-metallic abrasive pad, rubbing in the direction  
of the metal’s grain. If necessary, for particularly  
heavy spots, you may mix a thin paste of water and  
scouring powder, and apply it with a sponge. Be  
careful to apply light pressure and remember to rub  
only in the direction of the metal’s grain.  
5. Press the “Preheat Bakery 350” button to heat  
the oven to 350°F. Allow the oven to preheat for  
approximately 30 minutes before calibrating.  
Break in Period  
When the oven is new, heat the oven to “Preheat  
Bread 425), and leave the oven idle for one hour before  
beginning normal operation.  
Oven Cleaning  
5. e control panel surface is easily cleaned with  
hot water, soap, and a soft cloth. Do not use  
hard abrasives, solvent type materials, or metallic  
scouring pads since these will scratch and cloud the  
surface.  
Exterior  
• NOTE: Disconnect the oven from the power supply  
before cleaning or servicing.  
• Establish a regular cleaning schedule. Any spills  
should be wiped off immediately.  
6. Never spray the perforated areas or control panel  
with steam or water as this will allow moisture  
to enter the control cavity, which could damage  
electrical components.  
Tools: Mild detergent; hot and warm water; sponge  
or soft cloth; clean, dry cloth; possible non-metallic  
scour pad; possible scouring powder.

CLEANING AND MAINTENANCE  
Oven Cleaning  
Motor Care  
• e motor in this convection oven is maintenance  
Interior  
free since it is constructed with self-lubricating  
sealed ball bearings. It is designed to provide durable  
service when treated with ordinary care. ere are a  
few suggestions to follow on the care of the motor:  
• NOTE: Disconnect the oven from the power supply  
before cleaning or servicing.  
• Establish a regular cleaning schedule. Any spills  
should be wiped off immediately.  
• When the motor is operating, it cools itself  
internally by air entering at the rear of the motor  
case, provided proper clearance has been allowed.  
Tools: Supplied spray hose; brush; cloth  
• NOTE: e spray hose connection is located behind  
the front control panel. When cleaning the oven  
interior, attach the supplied hose to the water connector  
behind the control panel.  
• Since the blower wheel is in the oven cavity, it is  
at the same temperature as the oven. If the motor  
is stopped while the oven is hot, the heat from the  
blower wheel is conducted down the shaft and  
into the armature of the motor. is action could  
shorten the life of the motor.  
1. e oven should be allowed to cool sufficiently  
before beginning the cleaning procedure.  
2. Remove the racks, rack guides, and the baffle. Wipe  
each with a clean, damp cloth.  
• It is recommended that at the end of a bake or  
roasting period, when the oven will be idle for any  
period of time or before shutting down completely,  
the door be left open slightly and the “ON/OFF”  
button pressed to put the oven into Auto Cool  
Down. Once the internal temperature of the oven  
falls below 150°F (66°C), the fan will stop running  
and the display will show “OFF”. is feature  
protects the oven motor from pre-mature failure.  
Optimal cool down will be achieved with the door  
open slightly.  
3. Using the supplied spray hose, spray the inside of  
the oven lightly to remove any deposits.  
4. Wipe the interior with a clean damp cloth to remove  
any remaining deposits and spots.  
5. Brush the wheel as needed to remove any grease  
and/or particles.  
6. Carefully wipe the blower wheel and temperature  
probe with a clean damp cloth.  
7. Replace the baffle, rack guides, and racks. Return  
the spray hose to its storage compartment.
