CAUTION
NOTE
Outdoor Unit
AVOID:
●heat sources, exhaust fans, etc. (Fig. 2-2)
●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. 2-3)
●Install the outdoor unit above
snowfall line.
●Do not place objects on or sit
on the outdoor unit. Also, never
block the air intake/outlet or
exhaust. Distortion of the
outdoor unit or incomplete
combustion may result.
●Do not introduce foreign matter
into the air intake/outlet or
exhaust. Do not poke them with
such objects as a stick.
●provide a solid base (level concrete pad, concrete
block, 4 in. × 16 in. (10 × 40 cm) 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. 2-4).
●use lug bolts or equal to bolt down unit, reducing
vibration and noise.
2-1. 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. 2-5)
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.
