In case of multiple installations
●
Provide a solid base (concrete block, 10 × 40 cm beams or
equal), a minimum of 15 cm above ground level to reduce
humidity and protect the unit against possible water damage
and decreased service life. (Fig. 2-5)
●
Use lug bolts or equal to bolt down unit, reducing vibration
and noise.

In locations with strong wind, snow-proof ducting 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 provided 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.

(1) The platform should be higher than the max. snow depth.
(Fig. 2-7)

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.
