Shipping Carton
This should be inspected upon delivery. When received,
carefully examine for any shipping damage before
unpacking. If damage is discovered, the delivering carrier
should both specify and sign for the damage on your copy
of the delivery receipt.
Open the carton carefully making certain that all parts are
accounted for before packaging materials are discarded.
After unpacking, if damage is found, promptly report it to
the carrier and request a damage inspection promptly.
IMPORTANT: Failure to request an inspection of damage
within a few days after receipt of shipment absolves the
carrier from any liability for damage. You must call for a
damage inspection promptly.
Location
Locate your unit in the most convenient place and near a
grounded electric outlet. If units are placed on a counter-
top, the front should be 3" or more back from the edge to
avoid accidental tipping of the unit.
If possible, locate your unit out of direct sunlight and away
from heat sources such as a radiator, stove or heat duct.
Electrical
With the exception of Explosion-Proof models, all units
must be connected to a grounded outlet matching the
nameplate and/or the information furnished in this manu-
al.
If you are not sure about the outlet, you should contact a
qualified electrician for assistance.
The unit should always be connected to its own individual
outlet.
Explosion- roof models do not come supplied with a
cord and plug. Units must be hard-wired by a quali-
fied electrician.
Installation
Caution
DO NOT REMOVE, under any circum-
stance, the grounding prongs from the
3-prong power cord supplied with all
units. No cord/plug is supplied with
Explosion- roof units. Contact a
qualified electrician to hard-wire
unit.
Caution
DO NOT USE electrical extension
cords that may result in voltage loss
and possible hazardous operation.
