STANDARD UNIT SPECIFICATIONS
COMPRESSOR
Compact semi hermetic helicoidal twin screw compressors: the main screw (male, with five lobes) is driven directly by
the electric motor, while the secondary screw (female with six vanes) is driven by the primary one.
The intrinsic volumetric ratio is precisely planed to be applied in the field of air-conditioning with ecological refrigerant R-
134a. The screws are made from steel alloy and the axial bearings are in tandem configuration for greater sturdiness.
The seal is guaranteed by extremely accurate tolerances in the machining of all moving parts and by the specific
circulation of oil between the screws. Continuous modulation of cooling capacity (Stepless) with oilcontrol dynamic.
The free flow lubrication system resulting from pressure differences, is equipped with a highly efficient separator, level
indicator and oil filter (replaceable). An oil heater prevents excessive dilution of the oil by the refrigerant, and is
automatically activated at all stages where the compressor is switched off. The asynchronous three-phase two pole
motor is suction gas cooled, reduced load start of the star delta type or Part Winding (according the compressor’s size)
Fully protected electronic module, with safety sensor for monitoring discharge temperature, sensors for monitoring
maximum temperature of the windings, device to monitor the motor rotation direction and device to monitor absence of
phase. Incorporated silencer non return valve and shut-off valve on the compressor discharge.
Filter on the suction line, at the inlet to the compressor.
Automatic internal saftey valve between HP & LP.
STRUCTURE
The bearing structure is made from hot-galvanized and painted plate and the external panelling from pre-painted
aluminium, ensuring maximum weatherability. The uniform unit weight distribution is guaranteed by the base structure,
realized with galvanized and painted plate section bars, featuring holes and/or stirrups to simplify the unit lifting and
earthing.
INTERNAL EXCHANGER
Direct expansion exchanger with independent circuit on the refrigerant side for each compressor. The tube bundle is
removable and allows easy maintenance. The exchanger is made from a carbon steel shell. The high-efficiency tubes,
anchored to the tube plate by mechanical expansion, are made from copper, fluted to increase heat exchange and
studied to be used with the modern ecological refrigerants. In addition, complete with safety differential pressure switch
on the water side, antifreeze heater to protect against the risk of ice, and closed-cell heat insulation that prevents the
formation of condensate and heat exchange with the outside.
EXTERNAL EXCHANGER
Finned exchanger, made from copper pipes arranged in staggered rows and mechanically expanded for better
adherence to the collar of the fins. The exchangers are planned, designed and produced directly by CLIVET. The fins are
made from aluminium with a special corrugated surface, set a suitable distance apart to ensure maximum heat exchange
efficiency. The coils are complete with integral subcooling circuit which assures the correct refrigerant feeding of the
expansion valve. Available in different options as in optional list.
FAN
Helical fans with sickle-shaped blades with "Winglets" at the end, coupled directly to a three phase electric external rotor
motor with thermal protection incorporated in version IP 54. Housed in aerodynamically shaped nozzles to increase
efficiency and minimize noise levels. They are fitted with protective safety guard grilles.
REFRIGERANT CIRCUIT

GENERAL
This section lists some of the more common situations which, being beyond the control of the manufacturer, could be a
source of risk to persons or property.
DEFINITION OF DANGER AREA
The figure below highlights the area in which only authorised personnel may operate.
- External danger zone, identified by a precise area around the unit and its vertical projection on the ground in the case of
hanging unit.
- Internal danger zone, identified by the area that can be entered only after having intentionally removed the protecting
panels or parts of these.
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-and-yellow
switch), and 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.
- 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.
- 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.
REFRIGERANTS
- 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.
After any maintenance operation, they must be resealed in an open position; the non-observance of these instructions
could bring the risk of an explosion of the cooling circuit with possible injury to things and people.
- 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

the operation also in more critical environmental conditions. For special
conditions contact our Sales Office.
Warning: the still air condition is meant as absence of air flow to the unit.
Any wind condition can let air pass through the condenser coil thus
worsening the operating limits of the unit (see limits with air speed at 0,5 m/s
& 1 m/s). In order to avoid such situation, windbreak barriers are necessary.
The minimum ambient temperature is given for units equipped with low
ambient control or with ECObreeze fans. For standard unit without these
options, this value is of about 18°C with still air and unit operating at full
load.

Note: In any case, the unit should never be exposed to or operated,
transported and/or stored at temperatures below -10°C.
Note: the Standard unit shall never be exposed, at temperatures below -
10°C while supplied. On request it’s possible to take countermeasures for
the operation also in more critical environmental conditions. For special
conditions contact our Sales Office.
Note: the Standard unit shall never be exposed, at
temperatures below -10°C while supplied.
Warning: the still air condition is meant as absence of air flow to the unit.
Any wind condition can let air pass through the condenser coil thus
worsening the operating limits of the unit (see limits with air speed at 0,5 m/s
& 1 m/s). In order to avoid such situation, windbreak barriers are necessary.
The minimum ambient temperature is given for units equipped with low
ambient control or with ECObreeze fans. For standard unit without these
options, this value is of about 18°C with still air and unit operating at full

INSPECTION UPON RECEPTION
Check on arrival that the unit has not suffered damage during transit and that it is complete in every part as specified in
the order. In the event of visible damage/deficiencies being discovered, make a note immediately on the delivery
document with the comment: "CONDITIONAL ACCEPTANCE — CLEAR EVIDENCE OF DEFICIENCIES/DAMAGE
DURING TRANSIT", then inform both the supplier and the carrier of the details by fax and by registered mail with advice
of receipt not later than 8 days after taking consignment. Notifications sent after 8 days have elapsed will be ignored.
STORAGE
Shelter from: direct sunlight, rain, sand and wind
Temperature: maximum 60°C minimum -10°C
Maximum humidity: 90%
The respect of the instructions on the exterior side of the packaging assures the physical and functional integrity of the
unit for the final user’s advantage.
It is recommended to:
•Handle carefully
•Keep in a dry place
•Avoid putting other objects on top of the unit (respect the limits of levels of superimposition shown in the
package)
•Avoid placing the unit with thermoretractable protection under the sun since the pressure of the circuits can
assume values which activate the safety valves.
HANDLING
The operation of handling the unit must be carried out respecting the instructions of the safety norms in force (Legislative
Decree 626/94 and following modifications)
Before starting the handling operations:
•Verify that the lifting capacity of the means used is adequate to the unit weight
•Consider that the barycentre could be moved with respect to the center of the unit
•Before starting to lift, verify that the unit is at a stable balance
The following examples are indications; the choice of the means and of the handling modes will depend on factors, such
as:
The unit weight
•Type and overall dimensions of the unit
•Place and route for the handling (dirt yard, asphalted square, etc. )
•Condition of the place of destination (roof, square, etc.)
•Distances, drops and gradients.
labels / yellow brackets show the lifting points
use a spacer bar to avoid damaging the unit2 lifting points
use 2-boom tie rods
(2 cables/chains/straps for each unit side)
according to the unit type, holes and/or lifting
brackets are positioned in different points
