ELECTING INSTALLATION SITE
(See figure 1 and figure 2 )
1 Select an installation site where the following conditions are
fulfilled and that meets your customer's approval.
- Where optimum air distribution can be ensured.
- Where nothing blocks air passage.
- Where condensate water can be properly drained.
- Where the false ceiling is not noticeably on an incline.
- Where sufficient clearance for maintenance and service can
be ensured.
- Where piping between indoor and outdoor units is possible
within the allowable limit. (Refer to the installation manual of
the outdoor unit.)
- This is a class A product. In a domestic environment this
product may cause radio interference in which case the user
may be required to take adequate measures.
- Keep indoor unit, outdoor unit, power supply wiring and
transmission wiring at least 1 meter away from televisions
and radios. This is to prevent image interference and noise in
those electrical appliances. (Noise may be generated
depending on the conditions under which the electric wave is
generated, even if 1 meter is kept.)
2 Use suspension bolts for installation. Check whether the ceiling
is strong enough to support the weight of the indoor unit. If there
is a risk, reinforce the ceiling before installing the unit.
