Relocation
If you move out or if it is desired to relocate the air conditioner, consult your dealer. Special skills to
withdraw Freon, purge air and perform other operations are required.
Location:
Be careful of noise or vibrations
Wire
During cooling operation, the air conditioner will dry the room air, so please fix a pipe to drain all the
water away from the air conditioner.
Please mount the indoor unit more than four feet away from the TV set and the radio in order to
avoid picture and noise interference.
Powerful radio transmitters or any other devices radiating high frequency radio waves can cause
the air conditioner to malfunction. Please consult the dealer where you purchased the air conditio-
ner before installing it.
Do not mount the unit in a dangerous area with combustible gas or volatile chemicals.
If the air conditioner operates in an atmosphere containing oils (machine oil), salt (near a coastal
area), sulfide gas (near a hot spring), etc., such substances may lead to failure of the air conditioner.
Please fix the unit in a stable place to avoid the noise or vibrations.
The noise near the air outlet of the outdoor unit may enter the air exit.
Locate the outdoor unit where noise emitted by it or hot air from its air outlet will cause no nuisance
to your neighbors.
If the air conditioner sounds abnormal during operation, contact the dealer where you purchased the
air conditioner.
To avoid the electric shock, please link the air conditioner with the ground. The power cord to
the air conditioner has ground wiring, please do not alter.
Do not pull the power wiring hard.
When grounding the air conditioner, observe the local rules.
Use the correct fuse or circuit breaker.
If you want to change the power wiring, please contact your contractor.
INSTALLATION
Special functions
Refrigerant Leakage Detection(optional):
With this new technology, the display area will display EC (if applicable) and the LED indication
lamps continue flashing when the outdoor unit detects refrigerant leakage.
Louver Angle Memory Function(optional):
For some models, the machine is designed with louver angle memory function. Power failure
during operation or pressing the ON/OFF button on the remote controller will stop the unit
completely. When the power restores or pressing the ON/OFF button on the remote controller
again,the unit restarts automatically with the previous open angle of the horizontal louver by the
memory function. So we strongly recommend that the open angle of the horizontal louver should
not be set too small,in case the condensed water forms and drops from the horizontal louver.
Press the Manual control button and the open angle of the horizontal louver will be restored to
the standard angle.
