HOLDING CABINET NORMAL OPERATION
CAUTION:
HOT SURFACE
Inner surfaces of the unit
will be very hot during and
after operation.
Avoid touching the cabinet
when loading or removing
product.
First Use
Turn the cabinet on using the power switch located on the far left side of the
control panel. The control display will illuminate.
When the cabinet is first turned on, the temperature display will show the
current hardware / software revision, for example: “r26”. Then display will
then alternately flash “PrE” and the set point values.
To adjust the temperature or humidity setting, rotate the respective dial to
the desired set point and stop. After 3 seconds, if either setting is adjusted,
the newly adjusted value will be stored in the controllers memory. If the cabi-
net power is interrupted, the last value set will be the new value restored
upon power being restored.
It will take approximately 30 minutes for the cabinet to warm up to a factory
default setting of 160ºF (71°C). Once the set point is reached, a short alarm
burst will be heard to indicate that the cabinet has reached the set point.
Humidity system
This holding cabinet is equipped with a water reservoir and automatic fill
system (standard) that can be used to humidify the cabinet. The reservoir
will not automatically begin to fill until the lowest water level probe is sub-
merged. This is a safety feature that will prevent the automatic fill system
from operating if the reservoir has been removed.
To activate the auto fill system, the reservoir must be primed. Ensure that
water line is connected to the cabinet (upper end on left side of cabinet).
Pour potable water into the reservoir until the water touches the lowest level
probe. Once the lowest probe is in water, the fill valve will turn on and the
reservoir will begin to fill. Once the highest level probe senses water, the fill
solenoid will turn off.
Due to the differences in water supply conditions, it may be necessary to
calibrate the cabinet to properly sense your water supply. Please see pages
7-8 for the calibration procedures.
As the unit maintains the desired humidity level, water will be used from the
reservoir. When the water level drops below the low level probe, the fill sole-
noid will turn on again thus repeating the cycle. The holding cabinet is
equipped with a low water alarm, see the following page for details on the
alarm system.
Although the cabinet is equipped with an auto fill system, it is not necessary
to have the cabinet coupled to a water supply line. The reservoir can be
filled manually. As long as the low level probe is in contact with water, the
control can maintain the desired humidity setting.
Humidity settings at high levels will cause condensation to collect in the cab-
inet. A removable condensation pan is located under the base of the cabi-
net to collect excess water. Check periodically and empty when full.
Factory default setpoints:
- temperature: 160ºF (71°C)
- humidity: 50%
- low temp alarm:140ºF(60°C)
Operating ranges:
- temp alarm: 80ºF-180ºF
(27-82ºC)
- air temp: 90ºF-200ºF
(32-93ºC)
- humidity: OFF-90%
The factory default for the
temperature display is in ºF.
To change the display to
read in ºC, push in and hold
the view actual button for 10
seconds. The display will
now read in ºC.
To change the display temp
back to ºF, repeat the same
procedure above.
CAUTION:
STEAM HAZARD
This unit produces steam,
use caution when cleaning
or opening the doors.
MANUAL FILL OF WATER RESERVOIR

HOLDING CABINET NORMAL OPERATION (CONT)
CAUTION:
HOT SURFACE
Inner surfaces of the unit
will be very hot during and
after operation.
Avoid touching the cabinet
when loading or removing
product.
Low temperature alarm
The cabinet is equipped with a low temperature alarm feature. When the
alarm is active, the temperature display will indicate “LO” and then “TEMP”
and the audible alarm will sound. To silence the alarm, press the “alarm off”
button. If the actual temperature is still below the low temperature alarm set
point after 5 minutes, the alarm will sound again.
This alarm can be triggered by the door being left open, product that is much
colder than the temperature set point being placed in the cabinet or due to a
malfunction of the heating system.
To change the low temperature alarm set point, press and hold the “alarm off”
button while adjusting the temperature set point knob to the new desired val-
ue. Due to food safety concerns, the low temperature alarm should nev-
er be set below 140 degrees F (60°C).After 3 seconds, the controller will
accept the new set point. The new value will be stored in the controller
memory until the next time the value is changed.
The audible alarm for low cabinet temperature can be turned off. The factory
default is ON. To enter into the adjustment mode, push in and hold the
“alarm off” button until the alarm sounds. The display will read either (ON or
OFF). To change the status, push the temperature knob, which will function
as a toggle switch to select between ON or OFF. After 10 seconds, the con-
troller will accept the desired audible alarm function (either ON or OFF). If
OFF is selected, the temperature display will still indicate “LO” and “TEMP” if
the low temp alarm is tripped.
Low Water Alarm
The cabinet is equipped with a low water alarm feature. When water drops
below the low level probe, the control cuts power to the heating element used
to produce steam. If the water level is below the low probe for more than 5
minutes, an audible alarm will sound and the humidity display will indicate
“LO” and then “H2O”. This alarm can be triggered by a lack of water supply
or due to a malfunction of the humidity system.
The humidity display will normally show the set point value. To display the
actual humidity value, press the knob located next to the humidity display.
The actual temperature and humidity values will be displayed for 5 seconds
and then revert back to the respective set point values. To display only the
actual temperature or humidity, push in the respective adjustment knob.
The audible alarm for low humidity can be turned off. The factory default is
ON. To enter into the adjustment mode, push in and hold the (alarm off) but-
ton until the alarm sounds. The display will read either (ON or OFF). To
change the status, push the humidity knob, which will function as a toggle
switch to select between ON or OFF. After 10 seconds, the controller will
accept the desired audible alarm function (either ON or OFF). If OFF is se-
lected, the humidity display will still indicate “LO” and “H2O” if the low water
alarm is tripped.
Operating ranges:
-temperature: 90-200ºF (32-93ºC)
-temp alarm: 80-180ºF (27-82ºC)
-relative humidity: Off - 90%
The LO / H2O alarm can be
silenced by pressing the
alarm off button or by add-
ing water to the reservoir.
If the alarm off button is
pressed and no water is
added, the alarm will sound
again after 5 minutes.
