2-2-1. Installing the Unit in an Area with High Winds and in a Snowy Area

In locations with high winds, a wind-proof duct should be fitted and direct exposure to the wind should be avoided as much as possible. (Fig. 5e)

In regions with significant snowfall, the outdoor unit should be provided with a platform and snow-proof duct. (Fig. 5f)

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 ducting:

a)The outdoor fan may not run and damage to the unit may occur.

b)There may be no air flow.

c)The tubing may freeze and burst.

d)The condenser pressure may drop because of strong wind, and the indoor unit may freeze.

(1)The platform should be higher than the maximum snow depth. (Fig. 5g)

(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.
