12. How Yhe Unit Drains
On humid days with the air conditioner in use,
moisture may collect on the pan or the bottom
of the air conditioner. If the unit is positioned
properly, the moisture will gather towards the
back of the unit.This will not affect the operation
of the unit and the moisture will evaporate in
time. OccasionaJy the moisture will flow over
the back of the pan, but this will not affect the
operation of the unit. Never drill holes in the
pan under any circumstance.

lllUe d OllliSe tiH %Se Hds
The following sounds are normally heard during the operation of an air conditioner.
®Cool airflow movement as dictated by the set fan speed.
®Water sounds. This is normal since your air conditioner also acts as a dehumidifier.
Thus you will hear water sounds from water drops falling on the condenser.
®As the refrigerant flows through the inner sealed tubing, a rushing noise may be
Occur.
® Rattling or vibrating noises may be heard due to poor wall or window installation.
® High pitch compressor sound may be heard.

Before you install your air conditioner, check the following:
1) The unit is free of all obstructions inside and outside the room, e.g. drapes, curtains,
furniture, plants, shrubs, bushes, trees, other structures like buildings, garage, etc.
The air conditioner must have a clear, unobstructed airflow through the condenser to
remove heat.
2) The window is strong enough to hold the weight of the air conditioner. Extra brackets
or supports may be needed depending on your windows. (Brackets or supports not
provided in all models)
3) The windowsill and track are strong enough to hold the weigh of the air conditioner.
4) The wall is strong enough to hold the unit. Extra brackets or supports may be needed
depending on the wall. (Brackets or supports not provided in all models).
5) There is adequate and proper power supply near the air conditioner.
6) DO NOT use adapter plugs.
7) DO NOT use extension cords.
8) DO NOT cut or remove the ground prong.
9) DO NOT modify the plug or the electrical wall outlet in any way. Efplug does not
fit the electrical outlet have a certified electrician do the necessary change.

1) Using wood, 1" or more in thickness, build a wooden frame to fit the
casing/cabinet dimensions of the unit which you have purchased.
2) Measure the outside width and the height of the frame to determine the
cutout dimensions necessary for the opening in the wall. The depth of the
frame wiJJdepend on the depth of the walk The finished frame must be set
