2.7 Positioning
Positioning and installation
All units are produced for installation outdoors, on
balconies or on the ground, provided that the area is free
from obstacles that could hamper air fl ow towards the
condenser coils.
The unit must be installed on a robust and perfectly level
foundation; should the unit be installed on balconies
and/or attics, it could be necessary to use weight
distribution beams.
For installation on the ground, a strong cement base that
is at least 250 mm wider and longer than the unit must
be foreseen. Also, this base must be able to support
the weight of the unit as declared in the technical
specifi cations.
If the unit is installed in places that are easily accessible
for people and animals, it is advisable to install coil and
compressor section protection grates.
To ensure the best possible performance on the
installation site, the following precautions and
instructions must be followed:
•
Avoid air fl ow recirculation
•
Make sure that there are no obstacles to hamper
air fl ow.
•
Air must circulate freely to ensure proper intake
and expulsion.
•
Ensure strong and solid fl ooring to reduce noise
and vibrations as much as possible.
•
Avoid installation in particularly dusty
environments, in order to reduce soiling of
condenser coils.
•
The water in the system must be particularly clean
and all traces of oil and rust must be removed.
Installation of a mechanical water fi lter is required
for the unit’s input piping.

Minimum space requirements
Dimensional drawing shall be be respected to avoid
causing:
• Noise
•
Incorrect heat exchange and ventilation
•
Diffi cult maintenance or inaccessibility to
components
It is fundamental to respect minimum distances on all
Trane units, in order to ensure optimum ventilation for
the condenser coils. Limited installation space could
reduce the normal air fl ow, thus signifi cantly reducing
the unit’s performance and considerably increasing
consumption of electrical energy.
When deciding where to position the unit and to ensure
a proper air fl ow, the following factors must be taken
into consideration:
•
Avoid any warm air recirculation and insuffi cient
supply to the air-cooled condenser. Both these
conditions can cause an increase of condensing
pressure, which leads to a reduction in energy
effi ciency and refrigerating capacity. Thanks to
the geometry of their air-cooled condensers,
Trane units are less affected by bad air circulation
situations. Also, Trane software has a particular
ability for calculating the unit’s operating
conditions and for optimising the load under
abnormal operating conditions.
•
Every side of the unit must be accessible for post-
installation maintenance operations. Figure below
shows the minimum space required.
•
Vertical air expulsion must not be obstructed
as this would signifi cantly reduce capacity and
effi ciency. If the unit is positioned in such a way
as to be surrounded by walls or with obstacles of
the same height as the unit, it must be installed
at a distance of at least 2500 mm. If these
obstacles are higher, the unit must be installed at
a distance of at least 3000 mm. Should the unit
be installed without observing the recommended
minimum distances from walls and/or vertical
obstacles, there could be a combination of warm
air recirculation and/or insuffi cient supply to
the air-cooled condenser which could cause a
reduction of capacity and effi ciency. In any case,
the microprocessor will allow the unit to adjust
to new conditions by producing the maximum
available capacity, even if the lateral distance is
lower than recommended.
•
When two or more units are positioned side by
side, a distance of at least 3600 mm between
condenser coils is recommended.
