LOCATION
These units are designed for outdoor installations on
ground level, rooftop, balcony, and any other place that
is suitable for installation with reliable load bearing.
Location should be selected for minimum sun exposure
and away from boiler flues and other sources of
airborne corrosive or flammable gas that could attack
the ambient coils and steel parts of the unit. The units
must be installed with sufficient clearances for air
entrance to the condenser coil to ensure adequate
supply of fresh air, for air discharge away from the
condenser, and for servicing access.
If the units are located at a place where unauthorized
personnel could reach, isolation security measures shall
be taken, such as setting protective guard, to avoid
human sabotage and prevent the control cabinet from
being opened and the operating electrical component
from being exposed;
The highest point of the air conditioning system shall
not be 20m over the unit (for 20m higher, please consult
YORK Company);
In installations where winter operation is intended and
snow accumulations are expected, additional height
must be provided to ensure normal condenser air flow.
For places with special installation
requirements, please consult to the
building contractor or the architect and
designer or other professionals.
Noise Sensitive Locations
Efforts should be made to assure that the unit is not
located next to occupied spaces or noise sensitive areas
where unit noise level would be a problem.
Please make the unit face the place that is sensitive to
noise as far as possible to reduce the influence of
operating noise of the unit;
If the heat exchanger part is without block, protective
baffle plate can be added to reduce the influence of
operating noise of the unit.
Cold Climate Locations
If the unit is operating in low ambient temperature, be
sure to follow the instructions listed below.
1. A baffle plate installed on the airside of the unit is
recommended to prevent exposure to snow in winter.
2. In areas with large snow precipitation, make sure
the coil and fan will not be affected by the snow.
Construct a lateral canopy if necessary.
3. Deice before operating if the fan blades fail to
rotate after long time standby in snow.
FOUNDATION
The unit should be mounted on a flat and level
foundation, floor, or rooftop capable of supporting the
entire operating weight of the equipment. See
PHYSICAL DATA for operating weight. If the unit is
elevated beyond the normal reach of service personnel,
a suitable catwalk must be capable of supporting
service
personnel,
their
equipment,
and
the
compressors.
To ensure the outdoor unit is placed flat on the base, the
outdoor unit must be placed after confirming the plane
where the outdoor unit would be placed is even. After
the installation of the outdoor unit the outdoor unit shall
be examined whether it is leveled, and the angle of
inclination shall be smaller than 10°; for a unit with an
absorber, the level inspection shall be installed after the
installation of absorber;
There are installing holes on the foundation of the unit,
and they can be used to closely connect the unit and the
foundation;
Ground location
For the ground installation, the steel foundation of the
unit shall be placed on smooth and flat concrete
foundation. DO NOT connect the unit foundation with
the building foundation for fear that noise and vibration
would be transmitted;
