2-2. Shield for Horizontal Exhaust Discharge

It is necessary to install an air-discharge chamber (fi eld supply)
to direct exhaust from the fan horizontally if it is diffi cult to
provide a minimum space of 2 m between the air-discharge
outlet and a nearby obstacle. (Fig. 2-4)
CAUTION

2-3. Installing the Outdoor Unit in Heavy Snow Areas

In locations where wind-blown snow can be a problem, snow-
proof vents should be fi tted to the unit and direct exposure to
the wind should be avoided as much as possible. (Fig. 2-6) 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.
2-4. Precautions When Installing in Heavy Snow
Areas
a) The platform should be higher than the maximum snow
depth. (Fig. 2-5)
b) 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 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,
countermeasures must be taken to prevent the unit from
being overturned.
