Sanyo 3-WAY ECO-i SPW-C0705DZH8 Instructions D'installation page 22

Installation space
Install the outdoor unit where there is enough space for
ventilation. Otherwise the unit may not operate properly. Fig. 2-9
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 wall height is below 1800 mm)
* More than 100 mm
* More than
50 mm
* More than 100 mm
* However, be sure to ensure a space of 300 mm or
more at either the right side or the rear of the unit.
CAUTION
● Leave space open above the unit.
● Construct louvers or other openings in the wall, if
necessary, to ensure adequate ventilation.

N OT E
● Do not do any wiring or tubing within 300 mm 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.
2-3. Shield for Horizontal Exhaust Discharge
It is necessary to install an air-discharge chamber (field supply)
to direct exhaust from the fan horizontally if it is difficult to
provide a minimum space of 2 m between the air-discharge
outlet and a nearby obstacle. (Fig. 2-11)
CAUTION
In regions with heavy snowfall, the outdoor unit should
be provided with a solid, raised platform and snow-proof
vents. (Fig. 2-12)
