OPERATION
General
Use the following procedures to turn on, prepare, and shut
down the Heated Air Curtain Cabinets.
WARNING
Read all safety messages in the IMPORTANT SAFETY
INFORMATION section before operating this equipment.
Startup
1. Plug unit into a properly grounded electrical receptacle of
the correct voltage, size and plug configuration. See the
SPECIFICATIONS section for details.
2. Fill all the shelves of the unit with empty sheet pans.
• For enclosed units, make sure all pans are pushed
completely against the back of the cabinet.
• For pass-through units, make sure all pans are behind
the line next to the arrow inside each end of the cabinet.
NOTE: Keeping the sheet pans in the proper position allows
the air currents in the unit to flow properly and maintain
the required temperature.
3. Move the Power I/O (on/off) switch to the
I
(on) position.
• The heating elements and blowers will energize.
• The digital temperature controller will energize and the
current temperature of the cabinet or “LO” will appear
on the display. “LO” indicates the cabinet temperature
is below 70°F (21°C).
CAUTION
BURN HAZARD:
• Some exterior surfaces on unit will get hot. Use caution
when touching these areas.
• Pan/tray will be very hot upon removal—use oven mitt,
protective clothing, or pan gripper to remove.
4. On humidified units, set the humidity to the desired level
(refer to the “Setting the Humidity Level” procedure in this
section).
5. Set the air temperature to the desired temperature (refer
to the “Setting the Air Temperature” procedure in this
section).
6. Allow the unit 30 to 60 minutes to reach the setpoint
temperature before loading preheated food product onto
the sheet pans.
Shutdown
1. Move the Power I/O (on/off) switch to the
O
(off) position
and allow the unit to cool.
NOTE: A cooling fan inside the unit will run for a short time after
the unit is turned off.
2. Perform the “Daily Cleaning” procedure in the
MAINTENANCE section of this manual.
Setting the Air Temperature
1. Press the
key to enter temperature mode (“tSP” will
appear on the CABINET TEMPERATURE display).
2. Press the
key again to show the current temperature
setting.
3. Press the
key or
key to reach the desired
temperature.
The temperature range is 80°–175°F (27°–79°C) for
non-pass-through models and 80°–200°F (27°–93°C) for
pass-through models in single degree increments.
4. After the desired temperature is set, press the
to
confirm the setting.
NOTE: Temperature and humidity settings may vary depending
upon product make-up and consistency. The
cabinet
temperature
display shows the lowest temperature
point inside the cabinet, not the product temperature.
Setting the Humidity Level
1. Press the
key to enter humidity mode (“hSP” will
appear on the cabinet temperature display).
2. Press the
key again to show the current humidity level.
3. Press the
key or
key to reach the desired humidity
level. Humidity range is 0 through 5 (0 is no humidity, 1 is
the lowest amount of humidity, and 5 is the highest).
Control Panel
4. After the desired humidity level is set, press the
to
confirm the setting.
The capacity of the water reservoir permits uninterrupted
operation for approximately 4–8 hours, depending on the
settings. For manual fill models, when “LO H2O” is flashing on
the cabinet temperature display, add water to the reservoir. The
water reservoir refill capacity is approximately 96 ounces, or 3
quarts (2.8 liters).
WARNING
ELECTRIC SHOCK HAZARD: Overfilling can cause
electrical shock. Water reservoir is full when “LO H2O”
stops flashing on CABINET TEMPERATURE display. Stop
filling when “LO H2O” stops flashing on display.
