front or filter removed.
•
Failure to follow these precautions
could result in electrical shock, fire or
personal injury.
• If the air conditioner has a serial plate
rating of 115 volts and greater than 7.5
amps, it must have its own fuse or
circuit breaker, and no other device or
unit should be operated on that fuse
or circuit breaker.
• If the air conditioner has a serial plate
rating of 230 volts, it must have its
own fuse or circuit breaker, and no
other device or unit should be
operated on that fuse or circuit
breaker.
• We recommend that a qualified
electrician install unit in accordance
with the National Electrical Code and
local codes and ordinances.
• Use copper conductors of correct wire
gauge and protector size only.
•
Do not alter cord or plug end. Do not
remove warning label on cord.
Important Grounding Requirements
• Air conditioner has a three-prong
grounding plug on the power supply
cord, which must be plugged into a
properly grounded three-prong wall
receptacle for your protection against
possible shock hazard. For models up
to and including 7.5 amperes, use a
grounding type wall receptacle to
match the cord plug.
• For models above 7.5 amperes use a
single outlet grounding type wall
receptacle to match the cord plug.
Additional Safety Precautions
• Do not cut, alter or remove any of
the expanded polystyrene
(styrofoam) inside this air
conditioner.
•
Do not store or use gasoline or
other flammable vapors and
liquids in the vicinity of this or any
other appliance. The fumes can
create a fire hazard or explosion.
•
Do not introduce objects in the air
discharge area. This could cause
permanent damage.
•
Do not pour liquids on the air
conditioner as this could cause a
malfunction. With the unit
unplugged, use a damp cloth for
cleaning the unit.
Do not use strong solvents to clean
•
the air conditioner.
Clean the air conditioner filter
•
every two weeks to avoid
overheating caused by air
obstruction. Do not operate
without filter.
Do not obstruct the air intake area
•
of your air conditioner, as this
could cause overheating, thus
activating the unit’s security switch
and shutting off the unit.
Do not block air circulation to
•
outside louvers of cabinet.
•
Do not block air flow inside with
blinds, curtains, or furniture, or
outside with shrubs, enclosures, or
other buildings.
Do not run the air conditioner with
•
an outside protective cover in
place. This could result in fire or
mechanical damage within the air
conditioner
• Depending on the model, your air
conditioner may weigh as much as
95 pounds. To insure safe handling,
obtain the necessary help to lift
and position the unit during
installation and removal.
• Handle air conditioner with care.
Wear protective gloves whenever
lifting or carrying the unit.
Carefully inspect the location
•
where the air conditioner will be
installed. Be sure it will support the
weight of the unit over an
extended period of time.

bear evenly to prevent air leakage. NOTE: THE UNIT IS
APROX. 6” DEEPER THAN THE SLEEVE. THE UNIT WILL
PROTRUDE APROX. 6” FROM THE SLEEVE INTO THE ROOM.
When installation is complete, the unit must have a
rearward slope to prevent condensate water from
entering the room. (Fig. 10) Check with a level.
