(2) Obstructions on the front side and rear side (Left side, right
side and above the unit are opened). (Fig. 2-3)
* For compressor replacement, 50 cm or more is required on the
front side even when using the air discharge chamber.

In case of multiple installations
● Provide a solid base (concrete block, 10 × 40 cm beams or
equal), a minimum of 15 cm above ground level to reduce
humidity and protect the unit against possible water damage
and decreased service life. (Fig. 2-5)
● Use lug bolts or equal to bolt down unit, reducing vibration
and noise.

2-2. Air Discharge Chamber for Top Discharge

Be sure to install the air discharge chamber in the field when:
● it is difficult to keep a space of min. 1 m between the air
discharge outlet and an obstacle.
● the air discharge outlet is facing a sidewalk and discharged
hot air annoys passers-by. (Fig. 2-6)

2-3. Installing the Unit in Heavy Snow Areas

In locations with strong wind, snow-proof ducting should
likewise be fitted and direct exposure to the wind should be
avoided as much as possible.
■ Countermeasures against snow and wind
In regions with snow and strong wind, the following problems
may occur when the outdoor unit is not provided with a platform
and snow-proof ducting (Fig. 2-7):
a) The outdoor fan may not run and damage of the unit may be
caused.
b) There may be no airflow.
c) The tubing may freeze and burst.
d) The condenser pressure may drop because of strong wind,
and the indoor unit may freeze.

Without snow- With snow-proof
proof ducting ducting
(Low platform) (High platform)
In regions with significant snowfall, the outdoor unit should
be provided with a platform and snow-proof duct.
2-4. Precautions for Installation in Heavy Snow
Areas
(1) The platform should be higher than the max. snow depth.
Fig. 2-5
(Fig. 2-7)
(2) The 2 anchoring feet of the outdoor unit should be used for
the platform, and the platform should be installed beneath
the air intake side of outdoor unit.
(3) The platform foundation must be firm and the unit must be
secured with anchor bolts.
(4) In case of installation on a roof subject to strong wind,
countermeasures must be taken to prevent the unit from
being blown over.
