1 - INTRODUCTION
Prior to the initial start-up of the 30RQM/30RQP units, everyone
involved in the works should be thoroughly familiar with these
instructions and with the characteristics of the installation site, and
ensure these are respected.
30RQM/30RQP heat pumps 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.
They are designed to offer a service life of 15 years, assuming a
utilisation factor of 75%, which corresponds to approximately
100,000 operating hours.
The procedures in this manual are arranged in the sequence
required for installation, start-up, operation and maintenance of
the units. Ensure that you follow all the required safety precautions,
including those listed in this guide, such as: wearing personal
protective equipment (gloves, safety glasses, safety shoes), having
the appropriate tools, skills and qualications (electrical, air
conditioning, local legislation).
To find out whether these products comply with European
directives (machine safety, low voltage, electromagnetic
compatibility, pressure equipment, etc.) check the declarations of
conformity for these products.
1.1 - Specic features of 30RQP units
The 30RQP units differ from the 30RQM units by introducing
variable speed drives on all of the fans and optimising the overall
energy efciency of the unit depending on the operating conditions
(air temperature, circuit capacity). This improves the seasonal
efciency (SCOP and ESEER).
All fans in the same refrigerant circuit are controlled by a single
variable speed drive. Therefore, they operate together at the same
rotational speed. The rotational speed of each circuit is controlled
by an algorithm that continuously optimises the condensing
temperature in cooling mode or the evaporating temperature in
heating mode. This ensures optimal energy efciency of the units
(EER and COP) whatever the operating conditions.
1.2 - Installation safety considerations
After the unit has been received, and before it is started up, it must
be visually inspected for damage. Check that the refrigerant circuits
are intact, taking care to check that no components or pipes have
shifted or been damaged (following an impact, for example). If in
doubt, carry out a leak tightness check. If damage is detected
upon receipt, le a claim with the shipping company immediately.
Do not remove the skid or the packaging until the unit is in
its nal position.
These units can be safely moved with a fork lift truck, 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 label with the unit handling instructions, attached
to the unit).
Use slings with the correct capacity, and follow the lifting
instructions given on the certied drawings for the unit.
Safety can only be guaranteed if these instructions are
carefully followed. Failure to do so may result in damage to
the equipment and physical injury.
DO NOT OBSTRUCT THE PROTECTIVE DEVICES.
This applies to any valves tted on the refrigerant or heat
transfer uid circuits. Check whether the original protection
plugs are still present at the valve outlets. These plugs are
generally made of plastic and must be removed before
operation. If they are still present, please remove them. Fit
devices at the valve or drain piping outlets to prevent the
penetration of foreign bodies (dust, building debris, etc.) and
atmospheric agents (water can form rust or ice). These
devices, as well as the drain piping, must not impair operation
and must not lead to a pressure drop that is higher than 10%
of the control pressure.
Classication and control:
In accordance with the Pressure Equipment Directive and
national usage monitoring regulations in the European Union,
the protective devices tted to these machines are classied
as follows:
Safety
accessory(1)
Accessory for limitation of
damage in the event of an
external re(2)
Refrigerant Side
High pressure switch X
External relief valve(3) X
Rupture disk X
Fuse plug X
Heat transfer uid side
External relief valve (4) (4)
(1) Classied for protection in normal service situations.
(2) Classied for protection in abnormal service situations. These accessories are
sized for res with a thermal ow of 10kW/m2. No combustible matter should
be placed within 6.5 m of the unit.
(3) The instantaneous over-pressure limitation of 10% of the operating pressure
does not apply to this abnormal service situation.
The control pressure can be higher than the service pressure. In this case, either
the design temperature or the high-pressure switch ensures that the service
pressure is not exceeded in normal service situations.
(4) The selection of these relief valves must be made by the personnel responsible
for completing the hydraulic installation.
Do not remove these valves under any circumstances, even
if the re risk is under control for a particular system. There
is no guarantee that the accessories have been re-installed
if the system is changed or for transport with a gas charge.
When the unit is subjected to re, a safety device prevents
rupture due to over-pressure by releasing the refrigerant. The
uid can then break down into toxic residues when in contact
with ames:
• Stay away from the unit;
• Ensure the personnel in charge of extinguishing the
re are duly warned and issued with recommendations;
• Fire extinguishers appropriate to the system and the
refrigerant type must be easily accessible.
All factory-installed relief valves are lead-sealed to prevent
any calibration change.
The external relief valves must always be piped to a safe,
external location if the units are installed in a enclosed space.
Refer to the installation regulations, for example those of
European standard EN 378 and EN 13136. Discharge ductwork
must be installed in a way that ensures that people and
property are not exposed to vented refrigerant. As the uids
can be diffused in the air, ensure that refrigerant is discharged
away from building air intakes or that it is discharged into a
sufcient quantity of suitable absorbent material. Relief
valves must be checked periodically (See the paragraph on
“Maintenance safety considerations”).
If the relief valves are installed on a change-over valve, this
is equipped with a relief valve on each of the two outlets.
Only one of the two relief valves is in operation, the other one
is isolated. Never leave the change-over valve in the
intermediate position, i.e. with both ways open (Bring the
actuator in abutment, front or back according to the outlet to
isolate). If a relief valve is removed for checking or
replacement please ensure that there is always an active relief
valve on each of the change-over valves installed in the unit.
Provide a drain in the discharge duct, close to each valve, to
avoid an accumulation of condensate or rain water. All
precautions concerning handling of refrigerant must be
observed in accordance with local regulations.

1.3 - Pressure equipment and components
These products incorporate equipment or components under
pressure, manufactured by Carrier or other manufacturers. We
recommend that you contact your professional body to nd out
which regulations affect you as the operator or owner of pressure
equipment or components (declaration, re-qualication, re-testing,
etc.). The characteristics of this equipment/these components are
given on the name plate or in the regulatory documentation
supplied with the products.
These units comply with the European Pressure Equipment
Directive.
The units are intended to be stored and operated in an
environment where the ambient temperature is always within
the allowable temperature range indicated on the nameplate.
Do not introduce signicant static or dynamic pressure with
regard to the operating pressures used during operation, or
for tests in the refrigerant circuit or heat exchange circuits.
NOTE: Monitoring during operation, re-qualification, re-
testing and re-testing dispensation:
• Follow regulations on the monitoring of pressure
equipment.
• The user or the operator is usually required to create
and maintain a monitoring and maintenance register.
• In the absence of any regulations, or in addition to the
regulations, follow the guidance in EN 378.
• Follow the local professional recommendations,
whenever they exist.
• Regularly inspect the surface of the components for
signs of corrosion. To do this, check an uninsulated
part of the component or check for an accumulation of
rust at the insulation joints.
• Regularly check for the presence of any impurities (e.g.
sand, grit) in the heat transfer uids. These impurities
can cause wear and/or pitting corrosion.
• Install lters in the heat transfer uid piping.
• The reports from the regular checks carried out by the
user or operator must be included in the monitoring
and maintenance register.
Repair:
Any repair or modication of a pressurised container is
prohibited.
Only the replacement of the container with an original
manufacturer component is authorised. In this case, the
replacement must be carried out by a qualied operator.
The replacement of the vessel must be entered in the
monitoring and maintenance register.
Recycling:
The pressure equipment can be recycled in whole or in part.
After use, they may contain refrigerant vapours and oil
residue. Some parts are painted.
1.4 - Maintenance safety considerations
Carrier recommends the following table as a guide to completing
the monitoring and maintenance register (logbook) required by
EN 378-2:
Intervention Name of the
commissioning
engineer
Applicable
national
regulations
Verication
Organism
Date Nature (1)
(1) Maintenance, repairs, regular verications (EN 378), leakage, etc.
Engineers working on the electrical or refrigeration components
must be authorised, trained and fully qualied to do so. All work
on the refrigerant circuit must be carried out by a trained person,
fully qualied to work on these units. He/she must have been
specically trained on this equipment and system. All welding
operations must be carried out by qualied specialists.
30RQM/30RQP units use high pressure R-410A refrigerant (the
unit operating pressure is above 40 bar; the pressure at an air
temperature of 35°C is 50% higher than for R-22). Special
equipment must be used when working on the refrigerant circuit
(pressure measurement, charge transfer, etc.).
Do not clean the unit with hot water or steam. This may cause
the refrigerant pressure to rise.
Any manipulation (opening or closing) of a shut-off valve
must be carried out by a qualied and authorised engineer,
observing applicable standards (e.g. during draining
operations). The unit must be switched off during maintenance.
NOTE: The unit must never be left shut down with the liquid
line valve closed, as liquid refrigerant can be trapped between
this valve and the expansion device and lead to the risk of a
pressure increase. This valve is situated on the liquid line
before the lter drier.
Equip the engineers that work on the unit as follows:

brazing (2)
Protective gloves,
eye protection,
safety shoe,
protective clothing.

(1) We recommend to follow the instructions in EN 378-3.
(2) Performed in the presence of A1 refrigerant according to EN 378-1.
Never work on a unit that is still energized.
Never work on any of the electrical components until the
general power supply to the unit has been isolated.
Lock the power supply circuit upstream of the unit in the open
position during maintenance interventions.
If work is interrupted for any reason, check that all circuits
are powered off before resuming work.
CAUTION: Even if the unit has been shut down, the power
circuit remains energized, unless the unit or circuit disconnect
switch is open. Refer to the wiring diagram for further details.
Follow the appropriate safety guidelines. When working on
the fan deck, particularly if the discharge grilles have been
removed, isolate the power supply to the fans to prevent their
operation.
CAUTION: The option Power factor (231) and the variable
frequency drives (VFD) tted to the 30RQP units and the units
with options 116V, 116W or 28 have capacitor banks whose
discharge time is ve (5) minutes after disconnecting the
power supply.
After disconnecting the power supply to the electrical box,
wait for 5 minutes before accessing the electrical box or
variable drives.
Before any intervention, verify that there is no voltage present
on any accessible conducting parts of the power circuit.
It is recommended that an indicating device be installed to
check if any refrigerant has leaked from the relief valve.
The presence of oil at the outlet orice is a useful indicator
that refrigerant has leaked. Keep this orice clean to ensure
that any leaks are obvious. The calibration of a valve that has
leaked is generally lower than its original calibration. The new
calibration may affect the operating range. To avoid nuisance
tripping or leaks, replace or re-calibrate the valve.
CAUTION: If refrigerant circuit service valves are installed,
ensure the protective caps are fitted in order to avoid
leakages.

(1) From 01/01/2017, units must be equipped with a leakage detection system.
8. A logbook must be established for equipments subject to
periodic leak tests. It should contain the quantity and the
type of uid present within the installation (added and
recovered), the quantity of recycled uid, regenerated or
destroyed, the date and output of the leak test, the
designation of the operator and its belonging company,
etc.
9. Contact your local dealer or installer if you have any
questions.
PROTECTIVE DEVICE CHECKS:
• If no national regulations exist, check the protective
devices on site in accordance with standard EN378:
once a year for the high pressure switches, every ve
years for external relief valves.
The company or organisation that conducts a pressure switch test
must establish and implement detailed procedures for:
-Safety measures,
-Measuring equipment,
-Values and tolerances for cut-off and discharge devices,
-Test stages,
-Recommissioning of the equipment.
Please contact Carrier Service for this type of test. The test
principle set out here by Carrier does not involve removal of the
pressure switch:
-Verify and record the nominal values for activation of the
pressure switches and external relief devices (pressure relief
valves or rupture discs),
-Be ready to switch off the main disconnect switch of the power
supply if the pressure switch does not trigger (avoid over-
pressure or excess gas if there are valves on the high
pressure side on the recovery air exchangers, for example),
-Connect a pressure gauge protected against pulsations (lled
with oil with maximum pointer if mechanical), preferably
calibrated (the values displayed on the user interface may
be inaccurate in an instant reading because of the scanning
delay applied in the control)
-Complete an HP Test as provided by the software (refer to
the Control IOM for details).
Caution: If the test results in the replacement of the pressure
switch, it is necessary to recover the refrigerant charge; these
pressure switches are not installed on Schrader type
automatic valves.
Visually inspect the protective devices (relief valves, pressure
switches) at least once a year.
If the machine operates in a corrosive atmosphere, inspect
the devices more frequently.
Check regularly for leaks and, if detected, have these repaired
immediately.
Regularly check that the vibration levels remain acceptable
and close to those at the initial machine start-up.
Before opening a refrigerant circuit, drain and consult the
pressure indicators.
After an equipment failure, replace the refrigerant in
accordance with a procedure such as that described in NF
E29-795, or have a refrigerant analysis carried out at a
specialist laboratory.
If the refrigerant circuit remains open after an intervention
(such as a component replacement, etc.):
• Seal the openings if the duration is less than a day;
• If more than one day, charge the circuit with a dry, inert
gas (e.g. nitrogen)
The objective is to prevent penetration of atmospheric
humidity and the resulting corrosion of the unprotected
internal steel walls.
1.4 - Repair safety considerations
All parts of the system must be maintained by the personnel
responsible for such maintenance, in order to avoid any damage
or accidents. Faults and leaks must be repaired immediately. An
authorised technician must remedy the fault immediately. After
each repair of the unit, check the operation of all protective devices
and record operating readings for all parameters.
Comply with the regulations and recommendations given in the
safety standards for refrigerant systems and machines, such as:
EN 378, ISO 5149, etc.
If a leak occurs or if the refrigerant becomes contaminated (e.g.
by a short circuit in a motor or freezing of the BPHE), remove the
complete charge using a recovery unit and store the refrigerant
in mobile containers. The compressors cannot transfer the whole
refrigerant charge and can be damaged if used to pump-down.
The refrigerant charge should not be transferred to the high-
pressure side.
Detect and repair the leak, and recharge the circuit with the full
charge of R410A indicated on the unit's nameplate. Do not top up
the refrigerant charge. Only charge liquid refrigerant R-410A at
the liquid line.
Check the type of refrigerant before adding the full charge to
the machine.
1 - INTRODUCTION
6

Charging any refrigerant other than the original type (R410A)
will impair machine operation and can even cause irreparable
damage to the compressors. The compressors operating with
this refrigerant type are lubricated with a synthetic polyolester
oil.
Before any intervention on the refrigerant circuit, the complete
refrigerant charge must be recovered.
RISK OF EXPLOSION:
Never use air or a gas containing oxygen during leak tests to
purge ductwork or to pressurise a unit. Pressurised air
mixtures or gases containing oxygen can be the cause of an
explosion. Oxygen reacts violently with oil and grease.
Only use dry nitrogen for leak tests, with an appropriate tracer
gas if necessary.
If the recommendations above are not observed, this can
have serious or even fatal consequences and damage the
installations.
Never exceed the specied maximum operating pressures.
Check the maximum permissible test pressures on the high
and low pressure sides, consulting the instructions in this
manual and the pressures indicated on the unit's nameplate.
Do not unweld the refrigerant ductwork or any refrigerant
circuit component or cut these with a torch until all refrigerant
(liquid and vapour) as well as the oil have been removed from
the heat pump. Traces of vapour should be displaced with
dry nitrogen. Refrigerant in contact with an open flame
produces toxic gases.
The necessary protective equipment must be available, and
appropriate fire extinguishers for the system and the
refrigerant type used must be within easy reach.
Do not siphon refrigerant.
Avoid spilling liquid refrigerant on skin or splashing it into
the eyes. Use safety goggles and safety gloves. Wash any
uid spills from the skin with soap and water.
If refrigerant enters the eyes, immediately ush the eyes
thoroughly with water and consult a doctor.
Any accidental release of refrigerant, whether this is caused
by a small leak or signicant discharges following the rupture
of a pipe or an unexpected release from a relief valve, can
cause frostbites and burns to personnel exposed. Do not
ignore such injuries. Installers, owners and especially service
engineers for these units must:
-Create a procedure to ensure medical attention is sought
before treating such injuries;
-Provide rst-aid equipment, including equipment for
treating eye injuries.
We recommend that standard EN 378-3 Annex 3 is applied.
Never apply an open ame or live steam to a refrigerant
container. This can result in dangerous overpressure.
During refrigerant removal and storage operations, follow
applicable regulations. These regulations, permitting
conditioning and recovery of halogenated hydrocarbons
under optimum quality conditions for the products and
optimum safety conditions for people, property and the
environment are described in standard NF E29-795. Any
refrigerant transfer and recovery operations must be carried
out using a suitable transfer unit. 3/8” SAE connectors on the
liquid, suction and discharge lines are available on all units
for connection to the transfer unit. The units must never be
modied to add refrigerant and oil charging, removal and
purging devices. All these devices are factory tted on the
units. Please refer to the certied dimensional drawings for
the units.
It is dangerous and illegal to re-use disposable (non-
returnable) cylinders or attempt to rell them. When cylinders
are empty, evacuate the remaining gas pressure, and move
them to a designated place for recovery. Do not incinerate.
Do not attempt to remove components tted to the refrigerant
circuit or ttings while the machine is under pressure or while
it is running. Check that there is zero pressure in the circuit
and that the unit has been shut down and deenergized before
removing components or opening a circuit. When the
refrigerant circuit is opened to carry out a repair, see the
blanketing recommendations in the paragraph on
“Maintenance safety considerations”.
Do not attempt to repair or recondition a valve if there has
been any corrosion or build-up of foreign material (rust, dirt,
scale, etc.) on the valve body or mechanism. If necessary,
replace the device.
Do not install relief valves in series or backwards.
CAUTION: No part of the unit must be used as a walkway,
rack or support. Periodically check and repair or, if necessary,
replace any component or piping that shows signs of damage.
The ducts can break under the pressure and release
refrigerant, causing injuries.
Do not climb on a machine. Use a platform to work at height.
Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components.
For lighter components, use lifting equipment if there is any
risk of slipping or losing your balance.
Use only original replacement parts for any repair or
component replacement. Consult the list of replacement parts
that corresponds to the original equipment's specications.
Do not drain the heat transfer uid circuit without informing
the installation site technical maintenance department or
other competent body rst.
Close the shut-off valves on the water inlet and outlet and
drain the unit's hydraulic circuit before working on the
components installed on the circuit (screen lter, pump, water
ow sensor, etc.).
Periodically inspect all valves, ttings and pipes on the
refrigerant and hydraulic circuits to ensure that they do not
show any signs of corrosion or leaks.
It is recommended that ear defenders are worn when working
near the unit if it is running.

2.1 - Check equipment received
■ Check that the unit has not been damaged during transport
and that no parts are missing. If the unit has been damaged or
the shipment is incomplete, send a claim to the shipping
company.
■ Check the unit's nameplate to ensure it matches the model
ordered. The nameplate is attached in two places to the unit:
-On the outside of one of the unit frames,
-On the inside of the electrical panel door.
■ The unit nameplate must include the following information:
-Model number - size
-CE marking
-Serial number
-Year of manufacture and pressure and leak tightness test
date
-Fluid used for transport
-Refrigerant used
-Refrigerant charge per circuit
-OP: Min./max. allowable pressure (high and low pressure
side)
-OT: Min./max. allowable temperature
-(high and low pressure side)
-Pressure switch cut-out pressure
-Unit leak test pressure
-Voltage, frequency, number of phases
-Maximum current
-Maximum input power
-Unit net weight
■ Conrm that all accessories ordered for eld installation have
been delivered in perfect working order.
The unit must be checked periodically, if necessary removing
the insulation (thermal, acoustic), throughout its service life
to ensure that nothing has damaged the unit (handling
equipment, tools, etc.). If necessary, damaged parts must be
repaired or replaced. See also the section on “Maintenance”.
2.2 - Handing and positioning
2.2.1 - Handling
See the section on “Installation safety considerations”.
In some cases, uprights are added for transporting and handling
the unit. The uprights must be removed if necessary for access
or connection.
Important: 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.
2.2.2 - Positioning within the installation area
The machine must be installed in a place that is not accessible to
the public or protected against access by non-authorised persons.
If the unit is to be raised, ensure the machine's surroundings
permit easy access for maintenance operations.
Always refer to the "Dimensions and clearances" section to
conrm that there is adequate space for all connections and
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 drawing
supplied with the unit.
The typical applications of these units are heating and
cooling, which do not require earthquake resistance.
Earthquake resistance has not been veried.
CAUTION: Only attach slings at the designated lifting points
which are marked on the unit.
8

Before positioning 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
(elastomeric 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 a qualied design engineer.
-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.
-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).
-Bafes may be necessary to protect the unit from strong
prevailing winds. These must not restrict air ow into the unit.
CAUTION: Before lifting the unit, check that all casing panels
and grilles are securely xed in place. Lift and set down the
unit with great care. Tilting and jarring can damage the unit.
If 30RQM/30RQP units are hoisted with slings, it is advisable to
protect coils from accidental impacts. Use sleeves or a lifting beam
to spread the slings above the unit. Do not tilt a unit by more than
15°.
CAUTION: 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 heat exchanger. If a unit includes a
hydraulic module (options 116R, S, T, U, V, W), the hydraulic
module and pump piping must be installed in a way that does
not submit it to any strain. The hydraulic module pipes must
be tted so that the pump does not support the weight of the
pipes.
2.3 - Checks before system start-up
Before the start-up of the heat pump, the complete system,
including the heat pump, must be veried against the installation
drawings, dimensional drawings, system piping and instrumentation
diagrams and the wiring diagrams. Heat transfer uid temperatures
above the maximum recommended can lead to an increase in the
refrigerant pressure and can cause a loss of refrigerant due to the
relief valve discharge.
National regulations must be followed during these checks. If the
national regulation does not specify any details, refer to standard
EN 378 as follows:
External visual checks of the installation:
-Ensure that the machine is charged with refrigerant. Verify
on the unit nameplate that the ‘uid transported’ is that
recommended for operation, and is not nitrogen.
-Compare the complete system with the refrigeration system
and power circuit diagrams.
-Check that all components comply with the design
specications.
-Check that all protection equipment and documents provided
by the manufacturer (dimensional drawings, Pipe and
instrument diagram (PID), declarations, etc.) to comply with
the regulations are present.
-Verify that the environmental protection and safety devices
and arrangements provided by the manufacturer to comply
with the regulations are in place and compliant.
-Verify that all documents for pressure containers, certicates,
name plates, register, instruction manuals and documentation
provided by the manufacturer to comply with the regulations
are present.
-Verify that access and safety routes are unobstructed.
-Verify the instructions and guidelines to prevent the deliberate
discharge of refrigerant.
-Verify the installation of connections.
-Verify the supports and xing elements (materials, routing
and connection).
-Verify the quality of welds and other joints.
-Check the protection against mechanical damage.
-Check the protection against heat.
-Check the protection of moving parts.
-Verify the accessibility for maintenance or repair and to check
the piping.
-Verify the status of the valves.
-Verify the quality of the thermal insulation.
-Check the condition of 400 V cable insulation.
2.4 - Actual start-up
Always ensure you have read and fully understood the operating
instructions for the units before starting up the heat pump, and
ensure the following precautions have been taken:
-Check the water circulation pumps, the air handling
equipment and any other device connected to the water heat
exchanger.
-Refer to the manufacturer's instructions.
-Refer to the wiring diagram supplied with the heat pump.
-Ensure that there is no refrigerant leak.
-Check the tightening of xing clamps on all pipes.
-Check the power supply at the main connection point and
the order of phases.
-Check that the compressor crankcase heaters, and the
compressor head heaters if applicable, have been energized
for 6 hours before starting up the system.
-Open the suction shut-off valves on each circuit.
IMPORTANT: Commissioning and start-up must be supervised
by a qualied engineer.
-Start-up and operating tests must be carried out with a
thermal load applied and water circulating in the water
heat exchanger.
-All setpoint adjustments and control tests must be
carried out before the unit is started up.
-Refer to the Service guide.
Start up the heat pump.
Ensure that all safety devices are operational, checking
specically that the high pressure switches are activated and
