How To Install The Outdoor Unit - Panasonic U-8ME1E8 Mode D'emploi

SUPPLEMENT
2-2. Shield for Horizontal Exhaust Discharge
It is necessary to install an air-discharge chamber (fi eld supply)
to direct exhaust from the fan horizontally if it is diffi cult to
provide a minimum space of 2 m between the air-discharge
outlet and a nearby obstacle. (Fig. 2-4)
In regions with heavy snowfall,
CAUTION the outdoor unit should be
provided with a solid, raised
platform and snow-proof vents.
(Fig. 2-5)
2-3. Installing the Outdoor Unit in Heavy Snow Areas
In locations where wind-blown snow can be a problem, snow-
proof vents should be fi tted to the unit and direct exposure to
the wind should be avoided as much as possible. (Fig. 2-6) 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.
2-4. Precautions When Installing in Heavy Snow
Areas
a) The platform should be higher than the maximum snow
depth. (Fig. 2-5)
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.

3. HOW TO INSTALL THE OUTDOOR UNIT

3-1.Transporting
When transporting the unit, have it delivered as close to the
installation site as possible without unpacking.
Use a hook for suspending the unit. (Fig. 3-1)
CAUTION
● When hoisting the outdoor unit, pass ropes through the left
and right holes of the bottom plate as shown in the Figs.
3-1-1 to 3-1-3. The angle between the rope and top panel
must be 70°or more so that the rope does not come into
contact with the fan guard. Use two lengths of rope 7.5
meters long or longer.
● Hang the rope at an oblique angle of the four corners of the
bottom plate. If it is hung at other areas, the rope becomes
loose and the outdoor unit will be damaged or you may be
injured.
● Use protective panels or padding at all locations where the
rope contacts the outer casing or other parts to prevent
scratching. In particular, use protective material (such as
cloth or cardboard) to prevent the edges of the top panel
from being scratched.
