2-3. Shield for Horizontal Exhaust Discharge

It is necessary to install an air-discharge chamber (field supply) to direct exhaust from the fan horizontally if it is diffi- cult to provide a minimum space of 7 ft. between the air-dis- charge outlet and a nearby obstacle. (Fig. 2-8)

In regions with heavy snowfall,

CAUTION the outdoor unit should be provided with a solid, raised plat-

form and snow-proof ducting (field supply). (Fig. 2-9)

2-4. Installing the Outdoor Unit in Heavy Snow Areas

In locations where wind-blown snow can be a problem, snow-proof ducting (field supply) should be fitted to the unit and direct exposure to the wind should be avoided as much as possible. (Fig. 2-10) 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.

2-5. Precautions When Installing in Heavy Snow

Areas

a)The platform should be higher than the maximum snow depth. (Fig. 2-9)

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, coun- termeasures must be taken to prevent the unit from being overturned.
