4-3. Shield for Horizontal Exhaust Discharge

It is necessary to install an air-discharge chamber
(field supply) to direct exhaust from the fan horizontal-
ly if it is difficult to provide a minimum space of 2 m
between the air-discharge outlet and a nearby obsta-
cle.
CAUTION
4-4. Installing the Outdoor Unit in Heavy Snow
Areas
In locations where wind-blown snow can be a prob-
lem, snow-proof vents should be fitted to the unit and
direct exposure to the wind should be avoided as
much as possible. The following problems may occur
if proper countermeasures are not taken:
1
The fan in the outdoor unit may stop running, caus-
ing the unit to be damaged.
There may be no airflow.
The tubing may freeze and burst.
2
The condenser pressure may drop because of
strong wind, and the indoor unit may freeze.
