Select the suitable areas to install the unit with
approval of the user.
If there are 2 units of wireless type, keep them
at least 6 m away to avoid malfunction due to
cross communication.
Ensure that the air path is not blocked.
Ensure that condensate can drain properly.
Ensure that the ceiling is strong enough to
bear the weight of the indoor unit.
Sufficient clearance for maintenance and servicing
Piping between the indoor and outdoor units is
within the allowable limits. (refer to the installation
of the outdoor unit )
The indoor unit, outdoor unit, power supply wiring
and transmission wiring should be at least 1 meter
away from televisions and radio, to prevent
interference and noise in those electrical appliances.
(Noise may be generated depending on the
conditions under which the electric wave is generated,
even if one-meter distance is maintained.)
·
Use suspension bolts to install the unit, check
whether or not the ceiling is strong enough to support
the weight of the unit. If there is a risk that the ceiling
is not strong enough, reinforce the ceiling before
installing the unit.
When several indoor units are installed nearby, keep
them away for more than 4-5m.
