OUTDOOR UNIT ACCESS AND CLEARANCES
In selecting a proper location, the following criteria
must be considered:
a) The outdoor unit and the indoor unit must be
installed as close to each other as possible, within
10m. If longer tubing is required see table on
page 14 or consult your technical sales rep.
b) Outdoor unit installation should provide for:
1. Easy service access.
2. Minimum disturbance to the owner and nearby
neighbors.
3. A minimum distance of 100 mm from the wall
4. If installed in a closed place (balcony, attic, etc),
outdoor air vent must be provided to prevent
hot/cold air from recirculation through the
outdoor unit.
5. If several outdoor units are installed in the
same area, make sure that the hot air outlet
from one outdoor unit does not enter another
outdoor unit.
6. Verify that any wall on which the outdoor unit is
installed is capable of carrying the unit’s
weight. Do not install on a light unstable
structure susceptible to vibration.
7. When installing on a balcony above the first
floor, make sure that the outdoor unit location
allows easy access for removal of the top
cover and/or the entire unit, if necessary.
8. If the outdoor unit is installed in a non-
accessible location, long and flexible
refrigerant tubing and electrical cable must be
installed to allow the unit to be moved for
servicing.
9. Do not install the unit in a highly polluted area
in which the air is contaminated by oil mist, salt
or sulfuric gas.
