2-2. Outdoor Unit

AVOID:

Exhaust fan

heat sources, exhaust fans, etc.

damp, humid or uneven locations

indoors (no-ventilation location)

DO:

Hot air

Out- door unit

Heat source

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.

Installation Space

Install the outdoor unit where there is enough space for ven- tilation. Otherwise the unit may not operate properly. Fig. 2-6 shows the minimum space requirement around the outdoor units when 3 sides are open and only 1 side is shuttered, with open space above the unit. The mounting base should be concrete or a similar material that allows for adequate drainage. Make provisions for anchor bolts, platform height, and other site-specific installation requirements.

 

Leave space open above the

CAUTION

unit.

 

Construct louvers or other

 

 

openings in the wall, if nec-

 

essary, to ensure adequate

 

ventilation.

Fig. 2-5

Example of installation of 2 units (When wall height is below 6 ft.)

* More than 4 in.

* More than 4 in.

More than

 

2 in.

More than

 

1.7 ft.

* More than 4 in.

 

*However, be sure to ensure a space of 1 ft. or more at either the right side or the rear of the unit.

Fig. 2-6

NOTE

Do not do any wiring or tubing within 1 ft. of the front panel, because this space is needed as a servicing space for the compressor.

Ensure a base height of 4 in. or more to ensure that drainage water does not accumulate and freeze around the bottom of the unit.

If installing a drain pan, install the drain pan prior to installing the outdoor unit.

*Make sure there is at least 6 in. between the outdoor unit and the ground.

Also, the direction of the tubing and electrical wiring should be from the front of the outdoor unit.
