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 in a place that is not accessible
to the public and is protected against access by non-authorised
persons.
The machine is designed to be installed outdoor.
For more details on the di󰀨erent installation cases, see the A2L
refrigerant installation guide.
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 location is not subject to ooding.
■Wind can a󰀨ect the operation and performance of machines.
■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, see the gure opposite).
■The unit must be installed on a plinth designed to collect then
drain the water produced by the reversible units during the
defrost cycles. If there is some remaining water on the oor
and if temperature is negative, this water could turn into ice
and cause falls.
■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
effort 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.

4.6 - Positioning of potentially ammable zones
Electrics box side
60 cm
The complete unit, including all the options and accessories which are provided by the manufacturer, have been certied for use
with an A2L refrigerant.
To ensure this, the manufacturer complies with EN 378-2 §6.2.14 and has dened a potentially ammable zone using EN 60079-
10-1 in order to identify where no sources of ignition must be present.
The manufacturer has then designed the machine so that, if the unit is used in the manner for which it has been designed, there
are no internal sources of ignition in the potentially ammable zone inside the machine.
Therefore, the only residual risk is that a source of ignition is introduced into the potentially ammable zone by the user. This is
why the manufacturer has decided to show the potentially ammable zone around the machine (see the diagram above) into which
the user must not introduce any sources of ignition. This indication is only provided to help our customers to identify the limits of
the ammability risk.
However, the machine itself does not present any risk of explosion connected to the use of A2L refrigerant.
Note (the following information is provided by the manufacturer for guidance only. The application of the following directives is the
sole responsibility of the user):
In compliance with the directives 2009/104/EC and 1999/92/EC, these zones may be qualied as ATEX zones by the user on the
basis of their own risk analysis, for which they alone remain responsible. In accordance with the denition given by Annex I of the
directive 1999/92/EC, this zone may be classied as zone 2 since it may consist of a location where an explosive atmosphere
consisting of a mixture of air and ammable substances in the form of a gas is not liable to occur during normal operation or, if it
does occur, it only occurs for a short period of time.
If additional equipment is required (motorised valve, pump, etc.), it must be:
■Installed outside of the dened potentially ammable zone
■Certied as not being a source of ignition for the refrigerant used

EN-17 AQUACIAT™ LD/ILD

5.7 - Comments on electrical data notes
• AQUACIAT™ LD/ILD units only have one power connection point, located
directly upstream of the main disconnect switch.
• The control box includes:
- A main disconnect switch,
- The start-up and motor protection devices for each compressor, the fans and
the pumps,
- The control devices.
• Field connections:
All connections to the system and the electrical installations must be in accordance
with all applicable codes.
• AQUACIAT™ LD/ILD units are designed and built to ensure compliance with
these regulations. The recommendations of European standard EN 60204-1
(corresponding to IEC 60204-1) (Safety of machinery- Electrical equipment of
machines - part 1: General requirements) are specically taken into account
when designing the electrical equipment.
Notes
• Generally the recommendations of IEC 60364 are accepted as compliance
with the requirements of the installation regulation.
• Compliance with EN 60204-1 is the best means of ensuring compliance with
the requirements (§1.5.1) of the Machinery Directive.
• Annex B of standard EN 60204-1 species the electrical features used for the
operation of the units.
• The operating conditions for AQUACIAT™ LD/ILD units are described below:
1. Environment(1)
The classication of environment is specied in standard EN 60364:
- Outdoor installation(1),
- Ambient temperature range: Minimum temperature -20 °C to +46 °C,
- Altitude: AC1 of 2000 m or less (for the hydraulic module, see the paragraph
“Electrical data for the hydraulic module”),
- Presence of solid foreign bodies: Class AE3 (no signicant dust present)(1),
- Presence of corrosive and polluting substances, class AF1 (negligible),
- Competence of personnel: BA4 (trained personnel).
2. Compatibility for low-frequency conducted disturbances at class 2 levels
as per the IEC 61000-2-4 standard:
- Power supply frequency variation: +- 2Hz
- Phase imbalance : 2%
- Total Voltage Harmonic Distortion (THDV): 8%
3. The neutral (N) line must not be connected directly to the unit (if necessary
use a transformer).
4. Overcurrent protection of the power supply conductors is not provided with
the unit.
5. The factory installed disconnect switch(es)/circuit breaker(s) is (are) of a
type suitable for power interruption in accordance with EN 60947-3
(corresponds to IEC 60947-3).
6. The units are designed for connection to TN networks (IEC 60364).
In IT networks, if noise lters are integrated into the variable frequency
drive(s), this will render the machines unsuitable for their intended purpose.
In addition, the short-circuit holding current characteristics are modied.
Provide a local earth, consult competent local organisations to complete
the electrical installation.
AQUACIAT™ LD/ILD are designed to be used in domestic / residential and
industrial environments:
Machines that are not equipped with speed regulators or equipped with options
282A/B comply with the standard codes:
- 61000-6-3: General standards - Standard emission for residential, commercial
and light industry,
- 61000-6-2: General standards - Immunity for industrial environments
Machines equipped with one or more frequency inverters (options: 6B, 28, 12,
16, 15LS) comply with the standard:
- 61000-6-4: Emission standard for industrial environments
- 61000-6-2: General standards - Immunity for industrial environments
• Leakage currents: If protection by monitoring the leakage currents is necessary
to ensure the safety of the installation, the presence of a circuit with a
DC component as well as additional leakage currents introduced by the use of
variable frequency drives in the unit must be considered (options: 6B, 28, 12,
16, 15LS).
In particular, these protections must be:
- Suited to protecting circuits with AC and DC components.
- A reinforced immunity type protection with a threshold no lower than 150 mA
Note: If particular aspects of an actual installation do not conform to the
conditions described above, or if there are other conditions which should
be considered, always contact your local Ciat representative.
(1) The required protection level for this class is IP43BW (according to reference
document IEC 60529). All AQUACIAT™ LD/ILD units are IP44CW and full
this protection condition.
5 - PHYSICAL AND ELECTRICAL DATA FOR THE UNITS
AQUACIAT™ LD/ILD EN-18

6 - ELECTRICAL CONNECTION
Please refer to the certied dimensional drawings, supplied with
the unit.
6.1 - Power supply
The power supply must meet the specication on the unit’s
nameplate.
The supply voltage must be within the range specied in the
electrical data table.
For connections, refer to the wiring diagrams and certied
dimensional drawings.
Operation of the unit with an incorrect supply
voltage or excessive phase imbalance constitutes
misuse which will invalidate the manufacturer's
warranty. If the phase imbalance exceeds 2% for
voltage, or 10% for current, contact your local
electricity supplier at once and ensure that the unit
is not switched on until corrective measures have
been taken.
After the unit has been started up, the power supply must only
be disconnected for quick maintenance operations (one day
maximum). For longer maintenance operations or when the unit
is taken out of service, the power supply of the unit must be
maintained permanently (the heaters must be powered on).
6.2 - Voltage phase imbalance (%)
100 x max. deviation from average voltage
Average voltage
Example:
On a 400 V - 3 ph - 50 Hz supply, the individual phase voltages
were measured with the following values:
AB = 406 V; BC = 399 V; AC = 394 V
Average voltage = (406 + 399 + 394)/3
= 1199/3
= 399.7 (rounded up to 400 V)
Calculate the maximum deviation from the 400 V average:
(AB) = 406 - 400 = 6
(BC) = 400 - 399 = 1
(CA) = 400 - 394 = 6
The maximum deviation from the average is 6 V. The greatest
percentage deviation is: 100 x 6/400 = 1.5%
This is less than the permissible 2% and is therefore acceptable.
6.3 - Power connection/disconnect switch
The power connection of the unit is carried out at a single point
upstream of the unit’s disconnect switch.
The earth connection must be made in the main electrical box
on the PE lug opposite the cable gland plate.
6.4 - Recommended cable sections
Wire sizing is the responsibility of the installer, and depends on
the characteristics and regulations applicable to each installation
site. The following is only to be used as a guideline, and does
not make the manufacturer in any way liable.
After wire sizing has been completed, using the certified
dimensional drawing, the installer must verify the appropriate
means of connection and dene any modications necessary on
site.
The connections provided as standard for the customer-supplied
power supply cables are designed for the number and type of
cables listed in the table below.
The calculations of favourable and unfavourable cases are
performed by using the maximum current possible for each unit
tted with a hydraulic module (see the tables of electrical data
for the unit and the hydraulic module).
The study includes the standardised installation cases according
to IEC 60364: Cables with PVC (70 °C) or XLPE (90 °C) insulation
with copper core; routing in accordance with table 52C of the
standard.
The maximum length mentioned is calculated to limit the voltage
drop to 5 %.
Before connecting the main power cables (L1 - L2
- L3), always check 3 phases are in the correct order
(clockwise) before proceeding to the connection on
the main disconnect switch.

(1) Connection capacities actually available for each machine. These are dened according to the connection terminal size, the electrical box access opening dimensions,
and the available space inside the electrical box.
(2) Selection simulation result considering the hypotheses indicated.
(3) If the maximum calculated selection is for a 90 °C cable type, this means that a selection based on a 70 °C cable type can exceed the connection capacity actually
available. Special attention must be given to selection.
The protection against direct contact at the electrical connection point is compatible with the addition of fanout cables. The installer must determine whether these
are necessary based on the cable sizing calculation.
Note: The currents considered are given for a machine tted with a hydraulic module operating at the maximum current.
