INSTALLATION
ELECTRICAL CONNECTION
WARNING!!!! DO NOT USE EXTENSION CORDS (VOIDS WARRANTY)
Ground:
The electrical outlet must be provided with an efficient ground, and the voltage and the
frequency of the electrical line matches those indicated on the data plate.
If unsure about the efficiency of the ground, have your electrical circuit checked
by a qualified technician.
• Carefully remove carton or crate from unit. Remove all loose packing materials,
making sure that no small parts or accessories are lost. Inspect the unit for concealed
damage before discarding packing materials.
• It is the responsibility of the installer to comply with all local codes.
• Unlock brakes on casters and roll unit to area where it is to be used.
• Electrical installation should be made by a licensed electrician.
• Check unit nameplate for electrical requirements. Make sure that the thermostats are
all set to the “OFF” position. Connect the electrical power cord and plug to a properly
sized power source of the correct voltage.
• Supplied voltage must correspond with the voltage specified on the serial plate.
WARNING!: Improper voltage supplied to the unit will void the warranty.
Voltage variation can cause erratic operation and serious damage to the
electrical system.
• All external wiring should conform to the national, state and local electrical code
requirements. See electrical specifications listed in the back of this manual for more
details on your Holding Cabinet.

ELECTRICAL RATING
PROOFER OPERATING INSTRUCTIONS
1. Turn power switch ON.
2. Fill water pan with hot water.
3. Set thermostat at 100 degrees. Allow approximately 15 minutes to reach temperature.
4. Set the humidity control at #2 or #3 setting. At the proper setting your proofer door
will have a light haze on it. If water beads up and runs down the door, the setting is
too high. You may need to adjust according to atmospheric conditions.
Ideal proofing conditions consist of a temperature of 100 degrees and 60%-80% humidity.
Proofing times will vary depending on the handling and the type of dough products.
Sugar and yeast must be able to react properly which takes a certain amount of time.
This cannot be altered by adjusting the settings. Correct proofing is very important for a
successful bake.
Make sure your dough is completely thawed and at room temperature (if using frozen
dough products) before placing the products in the proofer! If not, it can take two to three
times longer to proof.
HINT: You may want to place the dough (from the retarder) on a room temperature pan
- NOT the cold pan it was just sitting on. This helps shorten the proofing time. When
putting cold pans in the proofer, you bring the temperature down, taking longer for it to
get back to the desired 100 degree temperature.
WARNING
Low water level or scale build-up in the water pan will cause premature failure of
the humidity system and will void the warranty.
