2. SELECTING THE INSTALLATION SITE
2-1. Outdoor Unit
AVOID:
●
heat sources, exhaust fans, etc.
●
damp, humid or uneven locations
●
indoors (no-ventilation location)
DO:
●
choose a place as cool as possible.
●
choose a place that is well ventilated.
●
allow enough room around the unit for air intake/
exhaust and possible maintenance.
Installation Space
Install the outdoor unit where there is enough space for
ventilation. Otherwise the unit may not operate properly.
The figure shows the minimum space requirement around
the outdoor units when 3 sides are open and only 1 side is
shuttered, with open space above the unit. The mounting base
should be concrete or a similar material that allows for adequate
drainage. Make provisions for anchor bolts, platform height, and
other site-specific installation requirements.
Example of installation of 2 units
(when 3 sides are open and only 1 side is shuttered)
* More than 300 mm
** More than
50 mm
More than
500 mm
** More than
50 mm
*** More than 60 mm
* Make a walk-in space behind the unit to erase maintenance
and servicing.
** When setting the anchor bolt to position “B” or “C”, make the
space between the unit and the wall more than 250 mm for
installation operation.
*** When setting the anchor bolt to position “B” or “C”, make the
space between the outdoor units more than 180 mm for
installation operation.
CAUTION
●
Leave space open above the unit.
●
Construct louvers or other openings
in the wall, if necessary, to ensure
adequate ventilation.

NOTE
●
Do not do any wiring or tubing within 30 cm of the front
panel, because this space is needed as a servicing space for
the compressor.
●
Ensure a base height of 100 mm or more to ensure that
drainage water does not accumulate and freeze around the
bottom of the unit.
●
If installing a drain pan, install the drain pan prior to
installing the outdoor unit.
* Make sure there is at least 150 mm between the outdoor
unit and the ground.
Also, the direction of the tubing and electrical wiring should
be from the front of the outdoor unit.
