2-7. Installing the Outdoor Unit in Heavy Snow
Areas
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. 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.
2-8. Precautions When Installing in Heavy Snow
Areas
a)
The platform should be higher than the maximum
snow depth.
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.
