2-3. Air Discharge Chamber for Top Discharge

Be sure to install an air discharge chamber (field sup- ply) in the field when:

●it is difficult to keep a space of min. 20 in. between the air discharge outlet and an obstacle.

●the air discharge outlet is facing a sidewalk and discharged hot air may annoy passers-by. Refer to Fig. 2-10.

2-4. Installing the Unit in Heavy Snow Areas

In locations with strong wind, snow-proof ducting (field supply) should be fitted and direct exposure to the wind should be avoided as much as possible.

■Countermeasures against snow and wind

In regions with snow and strong wind, the following problems may occur when the outdoor unit is not pro- vided with a platform and snow-proof 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.

2-5. Precautions for Installation in Heavy Snow Areas

(1)The platform should be higher than the max. snow depth. (Fig. 2-11)

(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.
