Section of this manual.

1. Plug unit into electrical receptacle, or turn on wall circuit
breaker . With the POWER switch turned to OFF the
display shows “POWER OFF.”

With the POWER Switch of f, the display may show
“PURGING”. This means the humidity has reached
95% inside the unit and the fan runs to help drop the
humidity . Once the humidity reaches 92%, “POWER
OFF” again shows in the display .

Slot

Even though POWER switch is OFF it does not dis­connect all electrical supplies to the controls.
Unplug power cord, or turn off wall circuit breaker
before servicing any electrical components, or
electrical shock could result.

2. Turn the POWER switch to ON, and the display
shows “PUSH TO PROOF”.

3. If the unit is to be used as a proofer, (80-140o F)
(27-60o C), press the HUMIDITY button within 10
seconds, while thedisplay still shows “PUSH
TO PROOF”. If not, allow unit to heat normally ,
(140o-210o F) (60o-99o C).

4. Open door of unit and pour up to 3 gallons of water
into bottom water pan, (minimum 1 gallon) up to the slot
on the concentration ring. See figure 3-2.

placing product in the cabinet. This allows the interior
conditions to stabilize.

3-4. OPERATION WITH 1. The LEDs above the TEMPERATURE and HUMIDITY
PRODUCT buttons go out when the desired temperature and

humidity are reached inside the cabinet. Place hot
product on pan and slide pan onto the racks of the
cabinet.

The minimum holding temperature for potentially
hazardous product is 150o F (66o C). Use the food
probe to accurately display food temperature. Also,
the cabinet product load capacity for the full size
units is 375 lbs. (170 kg.), and 125 lb. (57 kg.) for
the half-sized units. V iew the temperature at any
time by pressing .

A humidity error only shuts down the humidity system. If a humidity error occurs, and you want to
use the cabinet without humidity , turn the humidity off by following the directions for SP-4, Humidity
Setpoint, in Special Programming Section of this manual. Once the setpoint is off, the alarm stops,
but the error code shows in display . (Includes “E-12A”, “E-12B”, “E-17” and “E-18”).

• Turn switch to OFF position, then back to
ON; if the display shows “E-18”, check
and clean float switch; clean water pan;
have relay and water heater sensor
checked and replace if necessary; tighten
acorn nuts on water heater cover; make
sure 2 complete pieces of insulation are
under the water heater cover; if “E-18”
persists, have PC board replaced
