Electrical Shock Hazard

LOCATION

For proper operation and maximum performance, locate the
unit in an ambient air temperature of 70ºF (21ºC).

Avoid placement in areas near exhaust fans or where there
are active air movements.

For safe operation and maximum performance, locate the
unit at least 2” from any wall or combustible material. Avoid
storing flammable or combustible materials in, on or near the
appliance.

Unit must be on a solid level surface.

GROUNDING INSTRUCTIONS

This appliance is equipped with a cord having a grounding
wire with a grounding plug which must be plugged into an
outlet that is properly installed and grounded. In the event of
an electrical short circuit, grounding reduces the risk of elec­tric shock by providing an escape wire for the electric current.

WARNING—Improper use of the grounding can result in
a risk of electric shock. Consult a qualified electrician or

service agent if the grounding instructions are not completely
understood, or if doubt exists as to whether the appliance is
properly grounded.

The ground prong of the power

cord is part of a system designed to
protect you from electric shock in
the event of internal damage.

DO NOT cut off the large round
ground prong or twist a blade to fit
an existing receptacle.

IMPORTANT:
Not under warranty

Damage to unit due to being
connected to the wrong voltage or
phase is NOT covered by warranty.

WARNING:

Risk of personal injury

Unit is not waterproof, to avoid
electrical shock, keep unit and
counter from being submerged in
water. Do not operate if unit has
been in contact with water.

To prevent an electrical shock hazard between the
appliance and other appliances or metal parts in close
vicinity, an equalization-bonding stud is provided. An
equalization bonding lead must be connected to this
stud and the other appliances/metal parts to provide
sufficient protection against potential difference. The
terminal is marked with the following symbol:

START-UP

1. Prior to use, thoroughly clean the interior of the unit,
per the instructions in this manual.

2. Plug the power cord of the cabinet into a grounded out­let with a electrical service according to the electrical
information provided at right.

3. Set POWER switch to the “ON” position.

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.

Factory default setpoints:

- temperature: 160ºF

- low temp alarm: 140ºF

Operating ranges:

- temp alarm: 80ºF-180ºF

- air temp: 90ºF-200ºF

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.

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 setting, rotate the TEMP dial to the de­sired set point and stop. After 3 seconds, if setting is adjusted, the
newly adjusted value will be stored in the controller’s 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 160º F. Once the set point is reached, a
short alarm burst will be heard to indicate that the cabinet has
reached the set point.

NOTE: The holding cabinet section of this appliance
and drawer warmers can be operated independently of
one another. See pages 9-11 for operation instructions
for the drawer warmers.

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.

Factory default setpoints:

- temperature: 160ºF

- low temp alarm: 140ºF

Operating ranges:

- temp alarm: 80ºF-180ºF

- air temp: 90ºF-200ºF

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, loading of
product that is much colder than the temperature set point 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 tem-
perature alarm should not be set below 140 degrees F. After 3

HEATING OPTIONS
MOIST HEAT: Moist operation prevents food from drying out as

heat is applied to the warming chamber.
DRY HEAT: For some applications, you may want to store previ-

ously prepared foods in a dry-heat environment.

1. MOIST HEAT WITH PANS

A. The drawer warmers are designed to accommodate any
combination of standard-size, steam table pans.
B. Place a small amount of water in the drawer pan. Place
the steam table pans in the drawer pan.
C. Check the water level periodically, and add water when
necessary
D. Set the front air vent between fully clos ed and half open.
Actual setting will depend on the type and amount of product
stored in the drawer, the temperature setting, and the
frequency in which the drawer is opened.

2. DRY HEAT

A. To warm with dry heat, place the food directly into the empty
(i.e. no water) drawer pan.

3. MOIST HEAT WITH OPTIONAL HUMITROL RACK

A. To set for MOIST OPERATION, remove the Humitrol Rack
from the bottom of the drawer insert pan and carefully pour
approximately 2 quarts of water (1/2” depth) into the pan.
Reinstall rack.
B. When the drawer is closed, the Humitrol Rack allows water
vapor to rise through the stored product in the drawer. The
Humitrol Rack also decreases the sloshing effect of the water
in the pan when the drawer is opened.
C. Place the food directly on the rack. The rack is designed to
support the food off of the steam vents, where condensation
may form.
D. Check the water level in the pan periodically and add water
when necessary.
E. Set the front air vent between fully closed and half open.
Actual setting will depend on the type and amount of product
stored in the drawer, the temperature setting, and the
frequency in which the drawer is opened.
