INSTALLATION

Unit installation details:
unit mounting
refrigerant piping connections
Whatever type of installation is chosen for
the unit, the following installation rules must
be observed:
The location selected for unit installation must be capable
of withstanding the weight of the unit in its full operating
configuration.
Select a location where neither dust nor other foreign
bodies will clog the unit coil.
If the outdoor unit is installed on the ground, make sure that
the location is not liable to flooding.
Make sure that you know and apply any and all local
rules and regulations concerning the installation of air
conditioning equipment.
Use the vibration isolators provided to prevent vibration
transmission and resulting unnecessary noise.
Do not install the equipment in explosive environments.
Make sure that the surrounding atmosphere does not
contain noxious or dangerous substances such as oil
vapours or sulphur.
If the air conditioner is installed in a polluted area,
increase the frequency of maintenance operations.
Avoid installing the unit where it will be in direct sunlight,
especially if it is a cooling only model since direct sunlight
will increase condensing pressure and reduce unit efficiency.
Install units facing North whenever possible.
In particularly windy places, the unit should be installed so
that the prevailing wind does not interfere with air discharge
from the unit (configuration with the wind blowing onto the
side of the unit).
MOH heat pump unit : install the unit at least 10 cm above
ground level to facilitate drainage of defrost water and
prevent accumulation of ice. In effect, defrost water can
cause accumulation of ice under the unit during subfreezing
outdoor temperatures.
condensate water drainage connections

Wherever possible, install the unit where it will be protected
from rain, snow and runoff from overhanging structures.
In areas with heavy snowfall it is best to install the unit on
wall supports.
If condensates are not to be drained, do not install the elbow
supplied with the unit.
Make sure that the unit is installed level so that condensate
will drain off correctly.
In some regions. It is necessary to heat the bottom of the
condensate drainage pan and the condensate drainage
piping to avoid ice formation, and resulting ice build-up in
the fan compartment (heater strip must be at least 25 W/m).
