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)
CAUTION
●Install the outdoor unit above snowfall line.
●Do not place objects on or sit on the out- door 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. 5b).
●use lug bolts or equal to bolt down unit, reducing vibration and noise.
NOTE
It is recommended to use baffle plates for models CL1251, CL1852 and CL0951. 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 temper- ature in winter), baffle plates must be installed in front of the outdoor unit. (Fig. 5c)
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.
