2-2. Outdoor Unit
AVOID:
● heat sources, exhaust fans, etc. (Fig. 4)
● damp, humid or uneven locations.
DO:
● choose a place as cool as possible.
● choose a place that is well ventilated.
● allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 5a)
● provide a solid base (level concrete pad, concrete
block, 4" × 1'4" (10 × 40 cm) beams or equal), a mini-
mum of 4" (10 cm) above ground level to reduce
humidity and protect the unit against possible water
damage and decreased service life. (Fig. 5b)
● Install cushion rubber under unit’s feet to reduce
vibration and noise. (Fig. 5c)
● use lug bolts or equal to bolt down unit, reducing
vibration and noise.
● Install in a location where no antenna of a television
or radio exists within 10' (3 m).
2-3. Baffle Plate for the Outdoor Unit
(CLxx models only)
It is recommended to use baffle plates for models
CL0971 and CL1271. The baffle plates are not normally
required for the other models.
When the outdoor unit is installed in a position exposed
to strong wind (such as seasonal winds with low air tem-
perature in winter), baffle plates must be installed on the
outdoor unit. (Fig. 5d)
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. 5d, 5e, 5f, 5g, and 5h)
