2 - RECEIPT OF GOODS

2.3 - Positioning

The unit must be installed in a place that is not accessible to the
public, or is protected against access by unauthorised persons.
This machine is not intended to operate in an ATEX area.
The machine must be installed outdoors (open space). The volume
of air supplied to the condenser coils must not be restricted to
ensure the operation of the machine is not adversely affected.
In case of extra-high units, the machine environment must permit
easy access for maintenance operations.
For the centre of gravity coordinates, the position of the unit
mounting holes, and the weight distribution points, refer to the
certified dimensional drawings. Ensure the free space shown in
the dimensional drawings is respected to facilitate maintenance
and connection.
The typical applications of these units are cooling and heating,
which do not require earthquake resistance. Earthquake resistance
has not been verified.
Before refitting the unit, check that:
■ The chosen location can support the weight of the unit,
or that appropriate reinforcement measures have been taken,
■ The unit is installed level on an even surface (maximum
tolerance is 5 mm along both axes),
■ If the support structure is sensitive to vibration and/or noise
transmission it is advisable to insert anti-vibration mounts
(elastomer mounts or metal springs) between the unit and the
structure. Selection of these devices is based on the system
characteristics and the comfort level required and should be
made by technical specialists,
■ There is adequate space above and around the unit for
air to circulate and for access to the components
(see dimensional drawings),
■ The number of support points is adequate and that they are in
the right places,
■ If the optional anti-vibration mounts are present, their number
and position must comply with the indications given on the
certified dimensional drawing.,
■ The location is not subject to flooding,
■ For outdoor applications, avoid installing the unit in a location
where snow is likely to accumulate (in areas subject to long
periods of sub-zero temperatures, the unit should be raised),
■ Baffles may be necessary to deflect strong winds. However,
they must not restrict air flow into the unit,
All welding operations (connection to the hydraulic network) must
be performed by qualified welders. The Victaulic
the counter-flange must be removed before welding as a matter
of course.
IMPORTANT : Follow the disassembly procedure indicated
in the disassembly instructions

2.4 - Proximity to walls

To guarantee correct operation in most cases:
■ If h < H (2.3 m), minimum S = 3 m
■ If h > H or S < 3 m, contact your Carrier distributor to assess
the various installation options.

2.5 - Underneath a roof

The upper part of the machine (on top of the fans) must not be
covered.
If the floor space requires the machine to be partially covered,
contact your Carrier distributor to assess the various installation
options.

2.6 - Installation of multiple chillers

It is recommended that multiple chillers are installed in a single
row, arranged as shown in the example below, to avoid warm air
being recycled from one unit to another.
If the floor space does not allow this arrangement, contact your
Carrier distributor to assess the various installation options.
