Outdoor Unit
AVOID:
ã
heat sources, exhaust fans, etc. (Fig. 3)
ã
damp, humid or uneven locations.
DO:
ã
choose a place as cool as possible.
ã
choose a place that is well ventilated.
ã
allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 4)
ã
Install the outdoor unit
above snowfall line.
ã
Do not place objects
on or sit on the out-
door unit. Also, never
block the air intake/out-
let or exhaust. Distor-
tion of the outdoor unit
or incomplete combus-
tion may result.
ã
Do not introduce for-
eign matter into the
air intake/outlet or ex-
haust. Do not poke
them with such ob-
jects as a stick.
ã
provide a solid base (level concrete pad,
concrete block, 4 in.
×
16 in. (10
×

beams or equal), a minimum of 4 in. (10 cm)
above ground level to reduce humidity and
protect the unit against possible water
damage and decreased service life (Fig. 5).
ã
use lug bolts or equal to bolt down unit,
reducing vibration and noise.
3)
Baffle Plates for the Outdoor Unit
(CL
××
models only)
It is recommended to use baffle plates for model
CL1852. The baffle plates are not normally
required for the other models.
When the outdoor unit is installed in a position
exposed to strong wind (like seasonal winds
with low air temperature in winter), baffle plates
must be installed on the outdoor unit. (Fig. 6)
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.
