power outlet nearby. Only operate in an upright position. Do not use an extension cord.
b) Ensure you have space for air to flow around the unit, at least 30cm/12” from wall, curtains,
draperies, or heat sources to insure adequate air circulation. Any blockage can lead to
overheating of the air conditioner.
c) Handle with care to prevent any kink or bend in the exhaust hose.
d) The flexible exhaust hose can be extended from 12" to 60" for mounting. We recommend that
you keep the hose as short as possible to minimize possible loss back in the room.

and snap the hose connector into the
window slide bar opening as shown.
Please make sure the hose is firmly
attached to the connector that fits into
window slide bar.
.
