INSTALLATION and STARTUP

WARNING:

Risk of personal injury

Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure could
result in personal injury and prop­erty damage.

IMPORTANT:

Power cord is 10' long

If necessary, contact a licensed
electrician to install an appropriate
electrical circuit with correct NEMA
receptacle. See table on this page.

DO NOT use an extension cord.

CAUTION:

Electrical Shock Hazard

T

he 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.

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.

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.

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:

INITIAL 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 according to the voltage
and amperage specified on
the serial tag on the heating
module. This can be located
on the top right rear corner
of the heating unit.

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

metal surfaces. A slight emission of smoke is common
during the first few hours of operation.
