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.
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.

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.
IMPORTANT: Only attach slings to the designated lifting
points which are marked on the unit.
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 permitted loading at the site is adequate or that
appropriate strengthening 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.
- 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.
IMPORTANT: 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.

4.5 - Free spaces and installing several units
In multiple-chiller installations (maximum of four units), the free space between the sides of the units should be increased
to between 1000 and 2000 mm.
The height of the solid surface must not exceed 2 m.
NOTE: If the walls are higher than 2 m, contact the factory
Solid wall Solid wall
4.6 - Positioning of ATEX zones around the unit
Electrics box side
60 cm
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.

5.7 - Comments on electrical data notes
• AquaSnap 30RB/30RQ units have a single power connection point located
immediately upstream of the main disconnect switch.
• 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.
• The AquaSnap 30RB/30RQ 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.
• Conformance with EN 60204-1 is the best means of ensuring compliance (§1.5.1)
with 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 AquaSnap 30RB/30RQ units are described below:
1. Environment*
The classication of environment is specied in standard EN 60364:
- Outdoor installation*,
- 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)*,
- 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.
AquaSnap 30RB/30RQ machines are designed for use in domestic / residential
and industrial environments:
Machines that are not equipped with speed regulators or are equipped with
options 282A/B comply with general standards:
- 61000-6-3: General standards - Emission standard for residential, commercial
and light-industrial environments,
- 61000-6-2: General standards - Immunity for industrial environments
Machines equipped with one or several variable frequency drives (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 and derived currents introduced by the use of variable frequency
drive(s) on the machine must be taken into account (options: 6B, 28,12, 16,15LS).
In particular, these protections must be:
- able to protect circuits with AC and DC components.
- a reinforced immunity protection type, with an adjustment value of no less 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 Carrier representative.
* The required protection level for this class is IP43BW (according to reference
document IEC 60529). All AquaSnap 30RB/30RQ units are IP44CW and full
this protection condition.

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 certified
dimensional drawings.
WARNING:
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 %.
IMPORTANT:
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.

(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 in operation at maximum current.

6.5 - Power cable access routing
The power supply must conform to the specication on the chiller
nameplate. The supply voltage must be within the range given in
the electrical data table. For connections refer to the wiring
diagrams and the certied dimensional drawings.
WARNING: operating the chiller with an incorrect supply
voltage or excessive phase imbalance constitutes improper
use and will invalidate the Carrier warranty. If the phase
imbalance exceeds 2% for voltage, or 10% for current, contact
your local electricity supplier at once and ensure that the
chiller is not switched on until corrective measures have been
taken.
6.6 - Field-installed control wiring
Important: Field connection of interface circuits may lead to
safety risks: any modication to the electrics box must ensure
the equipment remains compliant with local regulations.
Precautions must be taken to prevent accidental electrical
contact between circuits supplied by dierent sources:
-The routing selection and/or conductor insulation
characteristics must ensure dual electric insulation.
-In case of accidental disconnection, conductor xing
between dierent conductors and/or in the control box
prevents any contact between the conductor ends and
an active energised part.
See the SmartVuTM control manual for 30RB/30RQ units
and the wiring diagram supplied with the unit for the eld
control wiring for the following functions:
- Evaporator pump interlock (mandatory)
- Remote on/o󰀨 switch
- Demand limit external switch
- Remote dual set point
- alarm, alert and operation report,
- Heating/cooling selection
6.7 - Electric and power reserve for the user
Control circuit power reserve:
After all possible options have been connected, the CT transformer
ensures the availability of 1 A of power for the control cabling on-
site on 24 V, 50 Hz.
