INSTALLATION

WARNING:

Risk of personal injury

Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes.

and property damage.

IMPORTANT:

If necessary, contact a licensed
electrician to install an appropriate
15 amp electrical circuit with correct
NEMA receptacle.

DO NOT use an extension cord.

CAUTION:

Electrical Shock Hazard

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.

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

active air movements.

a risk of electric shock. Consult a qualified electrician or

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