INSTALLATION and START-UP

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
20 amp electrical circuit with correct
NEMA receptacle.

DO NOT use an extension cord.

CAUTION:

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
