2-3. Outdoor Unit

AVOID:

●

heat sources, exhaust fans, etc. (Fig. 5a)

●

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. 5b)

●

provide a solid base (level concrete pad, concrete block,

Ч 1'4" (15 Ч 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)

●

Install cushion rubber under unit’s feet to reduce vibration

and noise. (Fig. 5e)

●

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).

2-4. Baffle Plate for the Outdoor Unit

(CLM models only)

It is recommended to use baffle plates for models

CLM1972, CLM2472 and CLM3172. 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 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)
