1. SAFETY PRECAUTIONS
Let the customer keep this installation manual because it •
is needed when the air conditioner or remote controller is
serviced or moved.
WARNING
This mark indicates procedures which, if
improperly performed, might lead to the
death or serious injury of the user.
For the air conditioner to operate satisfactorily, install it as •
outlined in this installation manual.
Installation work must be performed in accordance with •
national wiring standards by authorized personnel only.
Do not turn on the power until all installation work is •
complete.
CAUTION
This mark indicates procedures which,
if improperly performed, might possibly
result in personal harm to the user, or
damage to property.
When detecting the room temperature using the remote •
controller, please set up the remote controller according
to the following conditions.
If the remote controller is not located properly, the correct
room temperature will not be detected, and thus abnormal
conditions like “not cooled” or “not heated” will occur even
if the air-conditioner is running normally.
Locate where an average •
temperature for the room being air
conditioned will be sensed.
Do not locate directly exposed •
to the outlet air from the airconditioner.
Locate out of direct sunlight.•
Locate away from the infl uence of other heat sources.•
Do not touch the remote controller PC board and PC •
board parts directly with your hands.
Do not wire the remote controller cable together with •
or parallel to the connection cables, and power supply
cables of the indoor unit and outdoor unit. It may cause
erroneous operation.
When installing cable near a source of electromagnetic •
waves, use shielded wire.
Do not set the DIP switches, either on the air conditioner •
or the remote controller, in any way other than indicated
in this manual or the manual that is supplied with the air
conditioner. Doing so may result in improper operation.
