AVOID:
●
areas where leakage of flammable gas may be expected.
●
places where large amounts of oil mist exist.
●
direct sunlight.
●
locations near heat sources which may affect the
performance of the unit.
●
locations where external air may enter the room directly.
This may cause “condensation” on the air discharge ports,
causing them to spray or drip water.
●
locations where the remote controller will be splashed with
water or affected by dampness or humidity.
●
installing the remote controller behind curtains or furniture.
●
locations where high-frequency emissions are generated.
DO:
●
select an appropriate position from which every corner of the
room can be uniformly cooled.
●
select a location where the ceiling is strong enough to
support the weight of the unit.
●
select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
●
allow room for operation and maintenance as well as
unrestricted air flow around the unit.
●
the limitation of the tubing length between the indoor and
the outdoor units should be referred to the Installation
Instructions of the outdoor unit.
●
allow room for mounting the remote controller about 1 m off
the floor, in an area that is not in direct sunlight or in the flow
of cool air from the indoor unit.

Refer to the installation instruction manual provided with the indoor unit.
The product meets the technical requirements of EN/IEC 61000-3-3.
Decide the length and size of the power supply cable based on the maximum ampere tabulated above in accordance with the national wiring regulations.
Select the fuse(s) and/or circuit breaker(s) from the types and ratings suitable for the maximum ampere tabulated above in accordance with the national wiring regulations.
An RCD suitable for use with inverters, resistant to high frequency noise, is most suitable. RCD’s intended for protection to include high frequency currents are
unnecessary and should be avoided, as potentially causing nuisance tripping, in this application.
If capacity of power supply circuit and enforcement are not enough, it can causes the electric shock and a
