3.2 Installation
3.2.1 Suspension bolts
(1) Consider the pipe direction, wiring and
maintenance carefully, and choose the proper

3.2.2 The position of the suspension bolts and the pipes
(1) Mark the positions of the suspension bolts, the
positions of the refrigerant pipes and the drain pipes.
(2) The dimension are shown below.
Installation and Maintenance
·
Optimum air distribution is ensured.
·
The air passage is not blocked.
·
Condensate can drain properly.
·
The ceiling is strong enough to bear the weight of the
indoor unit.
·
A false ceiling does not seem to be at an incline.
·
Sufficient clearance for maintenance and servicing
is ensured.(See Fig.3.1.1 )
·
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 must be kept at least 3.3ft.(1m)
away from televisions and radio, this prevents image
interference and noise in electrical appliances.
(Noise may be generated depending on the conditions
under which the electric wave is generated, even if a
one-meter allowance is maintained.)
·
Do not install the indoor unit in a machinery shop or
kitchen where vapor from oil or its mist flows to the
indoor unit. The oil will deposit on the heat exchanger,
thereby reducing the performance of the indoor unit,
and may deform and in the worst case, break the
plastic parts of the indoor unit.
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.
ce the chamber
For bottom intake, repla
lid and the intake-side flange in the procedure listed
in below figures.
(1) Remove the intake-side flange, then remove the
chamber lid. Refer to Fig. 3.1.2 for the directions.
(2) Reattach the removed chamber lid in the orientation
shown in Fig. 3.1.3, reattach the removed intake-side
flange in the orientation as shown in Fig. 3.1.3.
