EN-3 AQUACIATPOWER™ LD/ILD

1 - INTRODUCTION AND SAFETY INSTRUCTIONS
The units are designed to cool water (for coolers) and cool or reheat water (for reversible heat pumps) for the air conditioning and
heating of buildings and industrial processes.
They are designed to provide a very high level of safety and reliability, making installation, start-up, operation and maintenance easier
and safer.
They will provide safe and reliable service if used within their application ranges.
For all safety instructions, please refer to the safety manual. A paper version is delivered with the machine, the digital version is available
in the same place as the IOM, (contact your local distributor).
In addition to this safety manual, the manufacturer states that the unit is designed for a maximum number of 120,000 start-ups.
This product contains fluorinated greenhouse gases governed by the Kyoto protocol (1997) and covered by European
regulation 517/2014 on uorinated greenhouse gases (Annex I):
- Refrigerant type: R32
- Global Warming Potential (GWP): 675 (as per AR4)
2 - RECEIPT OF GOODS
2.1 - Checking the equipment received
Check that the unit and the accessories have not been damaged during transport and that no parts are missing. If the unit and the
accessories have been damaged or the shipment is incomplete, send a claim to the shipping company.
Compare the name plate data with the order.
The name plate is attached in two places to the unit:
- On one side of the unit exterior,
- On the inside of the electrical panel door.
AQUACIATPOWER™ LD/ILD EN-4

3 - HANDLING AND POSITIONING
3.1 - Handling
Carrier strongly recommends employing a specialised company
to unload the machine.
Do not remove the subbase or the packaging until the unit is in its
nal position.
These units can be safely moved by trained personnel with a fork
lift truck with the correct capacity for the dimensions and weight
of the unit, as long as the forks are positioned in the location and
direction shown on the unit.
The units can also be lifted with slings, using only the designated
lifting points marked on the unit (labels on the chassis and a label
with all unit handling instructions, attached to the unit).
Use slings with the correct capacity, and follow the lifting
instructions on the certied dimensional drawings supplied.
Only attach slings to the clearly marked points on the
unit provided for this purpose.
It is advisable to protect coils against crushing while a unit is being
moved. Use struts or a lifting beam to spread the slings above the
unit. Do not tilt the unit more than 15°.
Safety when lifting can only be guaranteed if all these instructions
are followed. Otherwise, there is a risk of equipment damage or
injury to personnel.
3.2 - Positioning
The machine must be installed outdoors in a place that is not
accessible to the public and is protected against access by
non-authorised persons.
The machine must be installed outdoors. Installation indoors is
forbidden.
For extra-high units, the unit 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
certied 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 veried.
Before positioning the device, check that:
- The chosen location can support the weight of the unit, or that
the 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.
- The unit must be installed on a plinth designed to collect then
drain the water produced by the reversible units during the
defrost cycles.
- The location is not subject to ooding.
- Avoid installing the unit where snow is likely to accumulate
(in areas subject to long periods of sub-zero temperatures, the
unit should be raised).
- Ba󰀪es may be necessary to deect strong winds. These must
not restrict the unit's air ow.
Before lifting the unit, check that all enclosure panels
and grilles are securely xed in place. Lift and set
down the unit with great care. Tilting and jarring can
damage the unit and impair unit operation.
Never apply pressure or leverage to any of the unit's
panels or uprights; only the base of the unit frame is
designed to withstand such stresses. No force or
e󰀨ort must be applied to pressurised parts, especially
via pipes connected to the water type heat exchanger
(with or without the hydraulic module if the unit is
equipped with this). The hydraulic module pipes must
be tted so that the pump does not support the weight
of the pipes.
All welding operations (connection to the hydraulic network) must
be performed by qualied welders. The Victaulic®connection or
the counter-ange must be removed before welding as a matter
of course.
Specic instructions for AQUACIATPOWER™ ILD
In some cases, uprights are added for transporting and handling
the unit. The uprights must be removed if necessary for access
or connection.
Follow the disassembly procedure indicated in the
disassembly instructions.
- Undo the bolt (3).
- Remove the upright (2).
- Remove the plate (1).
Keep the uprights following start-up and ret them when moving
the unit.

4.4 - Positioning of ATEX zones around the unit
Electrical cabinet side
Due to the nature of the refrigerant in these units (A2L uid),
ATEX zones have been identied and positioned around the units,
as shown in the diagram opposite.
The ATEX zones, as dened, must only be entered by suitably
trained personnel equipped with the appropriate detection
material and tools for working in an ATEX zone.
ATEX zone 2 is involved.
The machines are designed to be installed outdoors, in a free
eld-type, ventilated area.
As the refrigerant used is heavier than air, it is essential that
installations joined to the unit prevent the retention of refrigerant
at the lowest point in the event of a leak.
4.5 - Installing several units
It is recommended to install multiple units in a single row, arranged
as shown in the example below, to avoid recycling air between
the units. If the oor space does not allow this arrangement, contact
your distributor to assess the various installation options.
