First Use
Turn the cabinet on using the power switch located on the far left side of the
control panel. Once the switch is turned on, 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 cabinet 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 will be used to humidify the cabinet. The reservoir will not automatically begin to fill until the lowest water level probe is submerged. 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. 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 solenoid 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 cabinet.
A removable condensation trough is located at the base of the door to collect
excess water. Check periodically and empty when full.
Water reservoir located at top left of cabinet interior.
To fill, pull out metal frame with pan. IF CABINET IS HOT, USE OVEN MITTS AND PRO-
CEED WITH CAUTION—FRAME AND WATER WILL BE HOT.
To remove, pull out metal frame. DO NOT REMOVE IF CABINET OR WATER IS HOT.
ALLOW CABINET TO COOL COMPLETELY. While holding metal frame, slide pan to rear
and then lower to clear the frame. To install, reverse procedure.

will be very hot during and
after operation.
Avoid touching the cabinet
when loading or removing
product.
The LO / H2O alarm can be
silenced by pressing the
alarm off button or by adding water to the reservoir.
If the alarm off button is
pressed and no water is
added, the alarm will sound
again after 5 minutes.
CAUTION:
WATER HAZARD
A water trough is located at
the base of the door to collect condensation. Make
sure to periodically check
and empty it regularly to
avoid overflow. The trough
can be removed and emptied by simply sliding it off
the bolts at the base of the
door.
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 af ter 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 value.
Due to food safety concerns, the low temperature alarm should never 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 controller 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 val ue. 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) button 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 selected, the humidity display will still
indicate “LO” and “H2O” if the low water alarm is tripped.

and wait for the cabinet to cool
to room temperature.
CAUTION:
Do not move cabinet
unless door is securely closed. Serious damage to
hinges and door may result if
bumped into tables, walls, or
other equipment when the
