G
choose a place as cool as possible.
G choose a place that is well ventilated.
G install in a location where at least two sides are unob-
structed, so that the flow of air at the intake port or
exhaust port is not blocked, and so that sufficient
space is ensured for maintenance to be carried out
without trouble. In general the top also must be unob-
structed. (Fig. 5b)
G
provide a solid base (level concrete pad, concrete block,
6" × 1'4" (15 × 40 cm) beams or equal), a minimum of 6"
(15 cm) above ground level to reduce humidity and
protect the unit against possible water damage and
decreased service life. (Figs. 5c and 5d)
A solid base must not cover
CAUTION
the hole of the bottom plate.
G
install cushion rubber under unit's feet to reduce vibration
and noise. (Fig. 5e)
G

2-4. Baffle Plate for the Outdoor Unit

NOTE
It is recommended to use baffle plates.
When the outdoor unit is installed in a position exposed to
strong wind (such as seasonal winds with low air tempera-
ture in winter), baffle plates must be installed on the outdoor
unit. (Fig. 5f)
This unit is designed so that the fan of the outdoor unit runs
at low speed when the air conditioner is operated at low
outdoor air temperatures. When the outdoor unit is exposed
to strong wind, the system pressure drops because of the
freeze protector.
Install a pair of windbaffle plates at the front and back of the
outdoor unit if it will be subject to strong wind during the
winter. (Figs. 5f, 5g, 5h, 5i, and 5j)
