We strongly discourage the use of an adapter due to potential safety hazards.
For temporary connections, use only a UL-listed adapter, available from most
local hardware stores. Ensure that the large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the power cord as
this can lead to eventual ground terminal damage.
WARNING: Never use the appliance with a broken adapter.
We strongly discourage the use of an extension cord due to potential safety
hazards. For temporary situations, use only CSA certified and UL listed 3-wire
grounded extension cords, rated 15 A, 125 V.

Clearance
Proper clearance enhances the cooling efficiency of the unit and prevents heat
radiation of the condenser.
1. If a storm window presents interference, fasten a 2" wide wood strip to the inner
window sill across the full width of the sill.The wood strip should be thick
enough to raise the height of the window sill so that the unit can be installed
without interference by the storm window frame.
2. See Figure. B. The top of the wood strip should be approximately 3/4" higher
than the storm window frame (Storm Window Frame) or wood strip (Outdoors)
to help condensation to drain properly to the outside.
3. Install a second wood strip (approximately 6" long by 11/2" wide and same
thickness as first strip) in the center of the sill flush against the back off the
inner sill.This will raise the L bracket as shown Figure. B.
4. If the distance between Storm Window Frame and Wood Strip Mounted on Top
of Inner Sill is more than 1", two of wood strips are not necessary.

Drain Pipe
In humid weather, excess water may
cause the Base Pan to overflow. To
drain the water, remove the Drain Cap
and secure the Drain Pipe to the rear
hole of the Base Pan.
Press the drain pipe into the hole by
pushing down and away from the fins
to avoid injury.
This air conditioner is equipped with a
slinger fan. (See drawing, below.)

Do not force
open or open to far.
1. Pull the inlet grille forward.
2. Remove the air filter from the front grille by pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40 C (104 F).
4. Gently shake the excess water from the filter and replace.
Cleaning The Air Conditioner
The front grille and Inlet grille may be
wiped with a cloth dampened in a mild
detergent solution.
The cabinet may be washed with mild
soap or detergent and lukewarm
water, then polished with Liquid Wax
for Appliances.
To ensure continued peak efficiency,
the condenser coils (outside of unit)
should be checked periodically and
cleaned if clogged with soot or dirt
from the atmosphere.
