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.
Unit must be on a solid level surface.
INSTALLATION and STARTUP
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 elec-
tric 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.
If necessary, contact a licensed
electrician to install an appropriate
20 amp electrical circuit with correct
NEMA receptacle.
DO NOT use an extension cord.
Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure could
result in personal injury and proper-
ty damage.
Damage to unit due to being
connected to the wrong voltage or
phase is NOT covered by warranty.
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 infor-
mation provided at right.
3. Set POWER switch to the “ON” position.
4. Do not load product into the cabinet. Allow the heat to
remove any residual oils which may adhere to inside met-
al surfaces. A slight emission of smoke is common dur-
ing the first few hours of operation.
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.
CAUTION:
Electrical Shock Hazard
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.

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.
1. Turn the cabinet on using the power switch located on the far left
side of the control panel. Once the switch is turned on, power indi-
cating light will illuminate.
2. To adjust the temperature setting, rotate the HEAT dial to the
desired set point*.
It will take approximately 30 minutes for the cabinet to preheat to
your setting.
Once cabinet reaches temperature setting, power indicating light will
go on and off as element cycles to maintain cabinet temperature
setting.
3. Load cabinet with pans or trays.
4. When removing items, start at the bottom and work up to the
top. This keeps food hotter and eliminates spillage onto lower
items.
*For food safety reasons, it is recommended that the holding
temperature be set at 140°F or higher.
Operating ranges:
- air temp: 90ºF-200ºF
