HANDLING
If handling operations are undertaken without adopting all
the necessary safety procedures and exercising due care,
the unit can fall or topple, causing damage — possibly
extremely serious — to persons and/or property, and to the
unit itself.
Ensure the unit is handled and manoeuvred as directed on
the packing and in the present manual, and in accordance
with local regulations.
In the event of refrigerant gas escaping, refer to the “Safety
datasheet” for the particular refrigerant.
INSTALLATION
Incorrect installation of the unit can result in water leaks,
accumulation of condensate, escape of refrigerant, electric
shocks, fire, as well as irregular operation or damage to the
unit itself.
Make certain that the installation is carried out only by a
qualified technician, also that the directions contained in
this manual are followed and local statutory regulations
observed.
In the event of the unit being installed in a site where there
is even the slightest risk of inflammable gas escapes and
consequently the possibility of such gases accumulating in
area around the unit, the risk of explosion and fire cannot
be discounted.
Take every care and precaution when selecting the
installation site.
Installation on a structure not able to bear the weight and/or
afford a secure anchorage of the equipment may cause the
unit to fall and/or topple, resulting in damage to persons or
property, or to the unit itself. Make certain that every care
and precaution is taken when positioning and securing the
unit.
If the unit is easily accessible to children, unauthorized
persons or animals, this is a situation that can give rise
accidents and injuries, perhaps serious. Install the unit in a
place where access is allowed only to authorized persons,
or install barriers or guards preventing unauthorized entry.
GENERAL RISKS
A smell of burning, smoke or other indications of serious
irregularity could signal the onset of situations liable to
cause damage to persons or property or to the unit itself.
Isolate the unit from the electrical power supply (red-andyellow) switch.
Contact an authorized service centre so that the source of
the problem can be identified and remedied.
Accidental contact with heat exchange coils, compressors,
pressure pipelines or other components can result in
wounding or burns, or both.
Always wear suitable clothing, including protective gloves,
when working in the danger area.
Maintenance or repairs carried out by unskilled operatives
can result in harm or damage to persons and property, or to
the unit itself. Always contact an authorized service centre.
Failure to close the panels of the unit, or to check that all
the fixing screws of the panels are properly tightened, can
result in harm or damage to persons or property, or to the
unit itself.
Verify periodically that all panels are closed and made
properly secure.
In the event of fire, the temperature of the refrigerant can
rise to the point that pressure will exceed safety levels and
perhaps cause fluid to be projected. It may also happen
that parts of the circuit isolated by closed valves will
explode.
Do not stand near safety valves, and never leave the valves
of the refrigerant circuit closed.
ELECTRICAL SYSTEM
If the power line connecting the unit to the a.c. supply is
incomplete, or if the connection is made with cables of
incorrect cross section and/or with insufficiently rated
protective devices, this can result in electric shock, toxicity
hazard, damage to the unit or fire.
All work on the electrical system should be carried out
referring to the wiring diagram and to the directions given in
this manual, and the system itself must be dedicated.
Failure to secure the cover enclosing electrical components
can lead to the infiltration of dust and water, ultimately
causing electric shocks, damage to the unit, or fire.
Always fasten the cover securely to the unit.
If live metal parts of the unit are not connected properly to
the earth system, they can cause electric shock or even
death by electrocution.
Make absolutely certain that the connection to the earth
system is made in accordance with correct practice.
Contact with live parts rendered accessible internally of the
unit when the guards are removed can result in electric
shock, burns or death by electrocution.
Before exposing these parts, make certain the isolating
switch on the power line to the unit is set to the OFF
position and padlocked, and post a warning sign.
M03I40M7-03 15/11/07 page 7
Contact with parts that could become live when the unit is
started up can result in electric shock, burns or death by
electrocution.
When there is no need for circuits to be powered up, set the
isolating switch on the power line to the OFF position,
padlock it and post a warning sign.
MOVING PARTS
Contact with the fan rotors can cause injury.
Before removing the protective grilles or the fans
themselves, make certain the isolating switch on the power
line to the unit is set to the OFF position and padlocked,
and post a warning sign.
Before removing the protective grilles or the fans
themselves, make certain the isolating switch on the power
line to the unit is set to the OFF position and padlocked,
and post a warning sign.
REFRIGERANT
In the event of safety valves coming into operation and
releasing refrigerant gas, persons in the vicinity can be
injured or suffer toxic effects. Always wear suitable clothing
and protective goggles when working in potential hazard
areas.
In the event of refrigerant gas escaping, refer to the “Safety
datasheet” for the particular refrigerant.
If an open flame or heat source is brought into contact with
the refrigerant, or the pressurized gas circuit should
overheat (e.g. during welding operations), this can cause
explosion or fire. Do not position any heat source within the
hazard area.
Maintenance or repair operations involving welding must be
carried out with the system emptied of refrigerant.
WATER SYSTEM
Defects affecting pipelines, connections or valves and other
control componentry can result in water being leaked or
sprayed from the system, occasioning damage to property
or causing short circuits in the unit.
Make certain all hydraulic connections are securely made,
following the directions given in the present manual.

M03I40M7-03 15/11/07 page 11
POSITIONING
GENERAL
For installing air-conditioning systems, it is necessary to
consider the following:
• the technical spaces necessary for the machine and
system
• the place where the machine will be installed
• the transport of thermal carrier fluids and relevant
connections to the unit:
o water
o air
o refrigerant (unit in more sections)
• electrical connections
If these aspects are not evaluated carefully, they can affect
the performances and the working life of the unit.
FUNCTIONAL CLEARANCES
When placing the unit, please respect the functional
clearances indicated in DIMENSIONS section.
The functional spaces need to be observed because of the
following:
• to guarantee the good operation of the unit
• to allow the performance of all maintenance operations
• to protect the authorized operators and exposed people
If more units are placed close to one another, the functional
spaces must be doubled.
POSITIONING
1. The units are designed for INDOOR installations,
performed in fixed positions and in areas accessible
only to qualified and authorized personnel
2. SAFETY VALVE (only if present on the unit) : the
installer is responsible for evaluating the opportunity of
installing drain tubes, in conformity with the local
regulations in force ( EN 378 )
3. Install the unit raised from the ground
4. avoid installations in places subject to flooding
5. Verify that the fixing/supporting points are level and
suitable to support the weight of the unit (see the
weight and the weights distribution)
6. It is recommended to put the unit on specific
antivibration devices
Each support point of the unit sustains a different
weight. Therefore, each anti-vibration device is sized for
a specific support point, and can only be placed there.
The anti-vibration devices must therefore be placed in
accordance with the instructions provided with them
and with the dimensional drawings in which the support
points are indicated by W1 , W2 , W3 etc .
On each anti-vibration device (if provided by CLIVET),
its identifying code is stamped, for example C6100100
Flexible joints are necessary on all the hydraulic/
aeraulic connections (the joints are not supplied by
Clivet)

WATER CONNECTIONS
GENERAL
Piping must be designed with the least possible number of
bends and head variations. If the pressure chute of the
installation is above the useful prevalence of the pump, the
water delivery capacity is reduced as well as, as a
consequence, the thermal exchange and the yield.
INTERCEPTING VALVES
Install on the input and output of the user parts
(exchangers, coils, humidifiers, etc) So that it will be
possible to carry out all the service operations and possible
substitutions without emptying the installation.
PRESSURE AND TEMPERATURE INDICATOR
Install on the input and output of the user parts
(exchangers, coils, humidifiers, etc) So that it will be
possible to carry out all the service operations.
AUTOMATIC OR MANUAL ESCAPE VALVES
Install the highest points of tubes in a way that the air can
escape form the circuit.
BLEEDING COCK
Install them at the lowest points of the circuit, so as to allow
emptying.
LEAKAGE TESTS
Before performing the insulation of the tubes, carry out a
leakage test.
TUBE INSULATION
All tubes of water must be insulated so that to avoid the
formation of condensation and thermal dispersions along
the tubes themselves. Verify that the insulation is the
vapour coil type. The connections for the air escape and for
the emptying must be out of the insulating thickness to
assure the accessibility.
CONNECTIONS SUPPORTS
The weight of the hydraulic connections must be supported
in the exterior of the unit so as not to stress the connections
of user devices (exchangers, coils, humidifiers, etc ) .
ANTI-VIBRATION DEVICES
In case of units with anti-vibration devices, it is necessary to
assemble elastic joints, even on water connections.
RISK OF FREEZE
If the unit and the relevant water connections are subject to
temperatures near 0°C:
• mix the water of the system with glycol
• protect the tubes with heating cables under the tubes
insulation
• empty the system by verifying that:
o no taps are closed so they can not trap the water,
even after emptying
o there are no low points where the water can
stagnate even after emptying; blow if necessary
INSTALLATION EMPTYING
The refilling of the water present in the installation increase
the oxidation phenomena and lime deposits.
If necessary empty only the interested system section and
anyway empty or refill the installation if necessary .
EXPANSION TANK
The installation must be kept at the right pressure by both
an expansion tank and a combined valve of pressure
reduction and discharge; if the components are present on
the unit, they must be installed on the installation. The
expansion tank must be dimensioned in function of the
water in the installation.
MAX. WORKING PRESSURE
10,5 bar evaporator
16 bar condenser
ARIES EFFECTS AND AIR BUBBLES CAN PRODUCE
THE OVERCOMING AND CAUSE WATER DROPS.
EXCHANGER USE SIDE
FILTER
It is very important for the water to be free of impurities. If it
is not, the efficiency of thermal exchange is diminished. In
worst cases, the exchanger can be irreparably damaged. If
the filter is not present on the machine, it must be
immediately installed upstream from the unit, in a position
which can be easily reached for cleaning.
The filter mesh must be :
• < 1 mm unit with 1 compressor
• < 1.5 mm multicompressor unit.
FLOW SWITCH
The flow switch must be present as a component of the
system, so as to ensure shutdown of the unit if water is not
circulating. It must be installed in a straight tract of the
tubes, not near the elbows, which can generate harmful
turbulence
UNFREEZABLE LIQUIDS
If the unit is used when the water temperature is lower than
+ 4°C, avoid the formation of ice by using unfreezable
liquids (ex. Ethilenic Glycol) in the necessary percentage.
The use must also be determined for ambient temperatures
near 0°C .
ANTIFREEZE RESISTANCES
If the unit is equipped with antifreeze resistances on the
exchanger side (standard or optional according to the
models), verify that they are electrically fed during periods
that the machine is stopped (night, weekends, long stops)
WASHING THE SYSTEM
Carefully wash the system by using clean water and
discharge it before connecting the unit.

The accumulation tank is necessary in the event of the following:
• the water in the system is very low
• the unit will not be used in a private house (in an industrial process or other)
RECOVERY EXCHANGER
OPTIONAL - The unit can be equipped with exchangers to
recover the condensation heat.
The recovery can be:
TOTAL
• with 100% recovery of the condensation heat
• the thermoregulation is performed by CLIVET control
system
PARTIAL
• with 20% recovery
• The customer is responsible for the management of the
circulation pump, valves, thermostats, etc
The recovery input water must not be below 25°C, in the
event that, wrongful operations and breakages of the unit
can occur .
Water connections must be performed carefully as for the
evaporator (filter, circuit washing, etc) .
Perform all necessary interventions to avoid the RISK OF
FREEZING (tubes insulation, emptying of circuit, addition of
glycol, anti-freeze resistances) .
Water temperature can reach high temperatures (up to
100°C), therefore:
• avoid the RISK OF BURNS by adopting the necessary
precautions (insulation of tubes, temperature detecting
station on water if the sanitary use is foreseen, etc)
• Install safety valves and specifically dimensioned
expansion tanks in the hydraulic circuit.
VICTAULIC CONNECTIONS
1. Take away the supplied connection union by acting on the connection joint Victaulic.
2. Weld the union to the installation pipe.
3. Perform the connection between the installation pipe and the evaporator, using the joint.
Do not weld the system pipe with the Victaulic connection joint attached.
The rubber gasket might be irreparably damaged

SYSTEM MEASURES ON SOURCE SIDE
FILTER
It is very important for the water to be free of impurities. If it
is not, the efficiency of thermal exchange is diminished. In
the worst cases, the exchanger can be irreparably
damaged. The filter, if not present on-board the machine,
must be installed immediately upstream from the unit, in a
position that is easily accessible for cleaning
FLOW SWITCH
Since it is a system component, it must always be included,
in order to ensure unit shutdown in the event of failure of
water circulation. It is to be installed in a straight section of
the pipes, and not near curves which generate harmful
turbulence.
ANTI-FREEZE SOLUTIONS
For use of the unit with ambient temperatures near 0°C,
use antifreeze solutions such as ethylene glycol to prevent
the formation of ice. Its use is also required when
geothermal probes are used.
SYSTEM WASHING
Before connecting the unit, carefully wash the system by
filling it and emptying it several times with clean water.
CONTROL OF FLOW RATE
This makes it possible to limit water consumption, increase
energy efficiency and extend the unit's operating limits.
It can be modified by using
1. Modulating motorized valve
2. Cut-off valve
3. Pressure switch valve
CUT-OFF VALVE
This allows cut-off of water on the source side whenever
the compressor is not running.
It is therefore advisable for systems with disposable water,
if there is no modulating valve
