Selecting The Installation Site; Outdoor Unit - Sanyo R410A Installation Instructions Manual

2. SELECTING THE INSTALLATION SITE

2-1. Outdoor Unit

AVOID:
● heat sources, exhaust fans, etc.
● damp, humid or uneven locations
● indoors (no-ventilation location)
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.
● use lug bolts or equal to bolt down unit, reducing vibration
and noise.
Installation Space
Install the outdoor unit where there is enough space for ven-
tilation. Otherwise the unit may not operate properly. Fig. 2-2
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 con-
crete or a similar material that allows for adequate drainage.
Make provisions for anchor bolts, platform height, and other
site-specific installation requirements.
CAUTION
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.
● Leave space open above the
unit.
● Construct louvers or other
openings in the wall, if nec-
essary, to ensure adequate
ventilation.
