4-2. Shield for Horizontal Exhaust Discharge
It is necessary to install an air-discharge chamber (field sup-
ply) 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. 4-4)
In regions with heavy snowfall,
the outdoor unit should be
provided with a solid, raised
platform and snow-proof
vents.(Fig. 4-5)
4-3. Installing the Outdoor Unit in Heavy Snow Ar-
eas
In locations where wind-blown snow can be a problem, snow-
proof vents should be fitted to the unit and direct exposure to
the wind should be avoided as much as possible. (Fig. 4-6)
The following problems may occur if proper countermeasures
are not taken:
The fan in the outdoor unit may stop running, causing the
unit to be damaged.
There may be no air flow.
The tubing may freeze and burst.
The condenser pressure may drop because of strong
wind, and the indoor unit may freeze.
4-4. Precautions When Installing in Heavy Snow
Areas
a) The platform should be higher than the maximum snow
depth. (Fig. 4-5)
b) The 2 anchoring feet of the outdoor unit should be used
for the platform, and the platform should be installed be-
neath the air-intake side of the outdoor unit.
c) The platform foundation must be solid and the unit must
be secured with anchor bolts.
d) When installing on a roof subject to strong wind, counter-
measures must be taken to prevent the unit from being
overturned.
