6.14 Evaporator water ow-rate
Check that the dierence between the temperature of exchanger return and supply water corresponds to power according to this formula:
unit cooling power (kW) x 860 = Dt (°C) x ow rate (L/h)
The cooling power is shown in the table of the GENERAL TECHNICAL DATA included in this manual, referred to specic conditions, or in the
tables on COOLING PERFORMANCE in the TECHNICAL BULLETIN referred to various conditions of use.
Check for water side exchanger pressure drops:
determine the water ow rate
measure the dierence in pressure between exchanger input and output and compare it with the graph on WATER SIDE EXCHANGER
PRESSURE DROPS
The measurement of pressure will be easier if pressure gauges are installed as indicated in the DIAGRAM OF SUGGESTED WATER CONNECTIONS.
6.15 Operating at reduced load
The units are equipped with partialization steps and they can, therefore, operate with reduced loads.
However a constant and long operation with reduced load with frequent stop and start-up of the compressor/s can cause serious damages
for the lack of oil return.
The above-described operating conditions must be considered outside the operating limits.
In the event of compressor breakdown, due to operating in the above-mentioned conditions, the guarantee will not be valid and Clivet spa
declines any responsibility.
Check periodically the average operating times and the frequency of the compressors starts: approximately the minimum thermal load
should be such as to need the operating of a compressor for at least ten minutes.
If the average times are close to this limit, take the proper corrective actions.
6.16 Scroll compressor
The Scroll compressors have only one rotation direction.
In the event it is reversed, the compressor is not immediately damaged, but increases its noise and jeopardises pumping.
After a few minutes, the compressor blocks due to intervention of the thermal protection.
In this case, disconnect power supply and invert 2 phases on the machine power supply.
Avoid the compressor working for a long time with contrary rotation: more than 2-3 of these anomalous start-ups can damage it.
To ensure the rotation direction is correct, measure the condensation and suction pressure.
The pressures must signicantly dier: upon start-up, the suction pressure decreases whereas the condensation one, increases.
6.17 Start-up report
Identifying the operating objective conditions is useful to control the unit over time.
With unit at steady state, i.e. in stable and close-to-work conditions, identify the following data:
total voltages and absorptions with unit at full load
•
absorptions of the dierent electric loads (compressors, fans, pumps etc)
•
temperatures and ows of the dierent uids (water, air) both in input and in output from the unit
•
temperature and pressures on the characteristic points of the refrigerating circuit (compressor discharge, liquid, intake)
•
The measurements must be kept and made available during maintenance interventions.
6.18 97/23 CE PED directive
97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well.
Refer to local regulations; briey and as an example, see the following:
Compulsory verication of the rst installation:
only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)
•
Certication of setting in service:
for all the units
•
Periodical verications:
to be executed with the frequency indicated by the Manufacturer (see the “maintenance inspections” paragraph)
•

8.4 Standby mode
If a long period of inactivity is foreseen:
turn o the power
•
avoid the risk of frost (empty the system or add glycol)
•
Turn o the power to avoid electrical risks or damages by lightning strikes.
With lower temperatures keep heaters turned on in of the electrical panel (option).
It’s recommended that the re-start after the stopping period is performed by a qualied technician, especially after seasonal stops or seasonal
switching.
When restarting, refer to what is indicated in the “start-up” section.
Schedule technical assistance in advance to avoid hitches and to guarantee that the system can be used when required.
8.5 Water side exchanger
It is very important for the exchanger to be able to provide the maximum thermal exchange, therefore it is essential for the inner surfaces to
be clean of dirt and incrustations.
Periodically check the dierence between the temperature of the supply water and the condensation temperature: if the dierence is greater
than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:
with circulation opposite to the usual one
•
with a speed at least 1,5 times higher than the nominal one
•
with an appropriate product moderately acid (95% water + 5% phosphoric acid)
•
after the cleaning rinse with water to inhibit the action of any residual product
•
8.6 Water lter
Check that no impurities prevent the correct passage of water.
8.7 Circulating pumps
Check:
no leaks
•
bearing status (anomalies are highlighted by abnormal noise and vibration)
•
the terminal protection covers are closed and the cable holders are properly positioned
•
8.8 Flow Switch
controls the operations
•
remove incrustations from the palette
•
8.9 Electric fans
Check:
the fans and the relative protection gridsare well xed
•
the fan bearings (evident by noise and anomalous vibrations)
•
the terminal protection covers are closed and the cable holders are properly positioned
•
8.10 Air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleaned from dust and deposits.
Remove all impurities from the surface.
Using an air pressure gun, clean the aluminum surface of the battery; be careful to direct the air in the opposite direction of the fan air
movement.
Hold the gun parallel to the ns to avoid damages.
As an alternative, vacumn cleaner can be used to suck impurities from the air input side.
Verify that the aluminum ns are not bent or damaged, in the event of damages contact the authorized assistance center and get the ns
straightened in order to restore the initial condition for an optimal air ow.

9 Accessories
9.1 Partial energy recovery
A conguration which enables the production of hot water free-of-charge while operating in the cooling mode, thanks to the partial recovery
of condensation heat that would otherwise be rejected to the external heat source.
The maximum capacity available from the partial recovery is equal to the 15% of the rejected heating capacity (cooling capacity + compressor
power input)
The recovery exchanger must be always maintained full of water
The lack of water amplies the noise generated by the operation
When the temperature of the water to be heated is particularly low, it is wise to insert a ow-rate control valve into the system water circuit,
in order to maintain the temperature at the recovery output at above 35°C and thus avoid the condensation of the refrigerant into the partial
energy recovery device.

9.3 CSVX - Couple of manually opeated shut-o valves
Il kit allows to isolate the water circuit at the inlet and outlet.
It includes:
no. 2 cast-iron shut-o buttery valves with fast ttings and activation lever with a mechanical calibration lock
•
no. 2 of quick connections
•
9.4 Fresh air probe
The external probe allows to automatically change the unit set point according to the external enthalpy (temperature + humidity).
It is then possible to optimize the unit energy eciency.
Positioning
The sensor has not to be inuenced by factors that can false the reading (for ex. direct solar irradiation, exhaust air by fan or other sources,
contact with the unit structure or other sources of heat, accumulations of snow/ice), it has therefore to be placed in a protected place (possibly
to the north), for example in an attic, under a terrace and if it is on a free wall, provide a small roong.

10.1 Disconnecting
Only authorised personnel must disconnect the unit.
Avoid leak or spills into the environment.
Before disconnecting the unit, the following must be recovered, if present:
refrigerant gas
•
anti-freeze solutions in the water circuit
•
Awaiting dismantling and disposal, the unit can also be stored outdoors, if the electrical, cooling and water circuits of the unit have 100%
integrity and are isolated, bad weather and rapid change in temperature will not result in any environmental impact.
10.2 Dismantling and disposal
The unit must always be sent to authorised centres for dismantling and disposal.
When dismantling the unit, the fan, the motor and the coil, if operating, may be recovered by the specialist centres for reuse.
All the materials must be recovered or disposed of in compliance with the corresponding national standards in force.
For further information on the decommissioning of the unit, contact the manufacturer.
10.3 Directive EC RAEE
The units covered by the legislation in question are marked with the symbol on the side.
With the aim of protecting the environment, all of our units are produced in compliance with Directive EC on waste electrical and electronic
equipment (RAEE).
The potential eects on the environment and on human health due to the presence of hazardous substances are shown in the use and
maintenance manual in the section on residual risks.
Information in addition to that indicated below, if required, can be obtained from the manufacturer/distributor/importer, who are responsible
for the collection/handling of waste originating from equipment covered by EC-RAEE. This information is also available from the retailer who
sold this appliance or from the local authorities who handle waste.
Directive EC-RAEE requires disposal and recycling of electrical and electronic equipment as described therein to be handled through
appropriate collection, in suitable centres, separate from collection for the disposal of mixed urban waste.
The user must not dispose of the unit at the end of its life cycle as urban waste, it must instead be handed over to appropriate collection
centres as set forth by current standards or as instructed by the distributor.

11 Residual risks
General description
In this section the most common situations are indicated,as these
cannot be controlled by the manufacturer and could be a source of
risk situations for people or things.
Danger zone
This is an area in which only an authorised operator may work.
The danger zone is the area inside the unit which is accessible only
with the deliberate removal of protections or parts thereof.
Handling
The handling operations, if implemented without all of the protection necesssary and without due caution, may cause the drop or the
tipping of the unit with the consequent damage, even serious, to
persons, things or the unit itself.
Handle the unit following the instructions provided in the present
manual regarding the packaging and in compliance with the local
regulations in force.
Should the refrigerant leak please refer to the refrigerant “Safety
sheet”.
Installation
The incorrect installation of the unit could cause water leaks,
condensate accumulation, leaking of the refrigerant, electric shock,
poor operation or damage to the unit itself.
Check that the installation has been implemented by qualied
technical personnel only and that the instructions contained in
the present manual and the local regulations in force have been
adhered to.
The installation of the unit in a place where even infrequent leaks
of inammable gas and the accumulation of this gas in the area
surrounding the area occur could cause explosions or res.
Carefully check the positioning of the unit.
The installation of the unit in a place unsuited to support its weight
and/or guarantee adequate anchorage may result in consequent
damage to things, people or the unit itself.
Carefully check the positioning and the anchoring of the unit.
Easy access to the unit by children, unauthorised persons or animals
may be the source of accidents, some serious.
Install the unit in areas which are only accessible to authorised
person and/or provide protection against intrusion into the danger
zone.
General risks
Smell of burning, smoke or other signals of serious anomalies may
indicate a situation which could cause damage to people, things or
the unit itself.
Electrically isolate the unit (yellow-red isolator).
Contact the authorised service centre to identify and resolve the
problem at the source of the anomaly.
Accidental contact with exchange batteries, compressors, air delivery tubes or other components may cause injuries and/or burns.
Always wear suitable clothing including protective gloves to work
inside the danger zone.
Maintenance and repair operations carried out by non-qualied
personnel may cause damage to persons, things or the unit itself.
Always contact the qualied assistance centre.
Failing to close the unit panels or failure to check the correct
tightening of all of the panelling xing screws may cause damage to
persons, things or the unit itself.
Periodically check that all of the panels are correctly closed and
xed.
If there is a re the temperature of the refrigerant could reach values
that increase the pressure to beyond the safety valve with the
consequent possible projection of the refrigerant itself or explosion
of the circuit parts that remain isolated by the closure of the tap.
Do not remain in the vicinity of the safety valve and never leave the
refrigerating system taps closed.
Electric parts
An incomplete attachment line to the electric network or with incorrectly sized cables and/or unsuitable protective devices can cause
electric shocks, intoxication, damage to the unit or res.
Carry out all of the work on the electric system referring to the
electric layout and the present manual ensuring the use of a system
thereto dedicated.
An incorrect xing of the electric components cover may lead to
the entry of dust, water etc inside and may consequently electric
shocks, damage to the unit or res.
Always x the unit cover properly.
When the metallic mass of the unit is under voltage and is not
correctly connected to the earthing system it may be as source of
electric shock and electrocution.
Always pay particular attention to the implementation of the earthing system connections.
Contact with parts under voltage accessible inside the unit after
the removal of the guards can cause electric shocks, burns and
electrocution.
Open and padlock the general isolator prior to removing the guards
and signal work in progress with the appropriate sign.
Contact with parts that could be under voltage due to the start up
of the unit may cause electric shocks, burns and electrocution.
When voltage is necessary for the circuit open the isolator on the
attachment line of the unit itself, padlock it and display the appropriate warning sign.
Moving parts
Contact with the transmissions or with the fan aspiration can cause
injuries.
Prior to entering the inside of the unit open the isolater situated
on the connection line of the unit itself, padlock and display the
appropriate warning sign.
Contact with the fans can cause injury.
Prior to removing the protective grill or the fans, open the isolator
on the attachment line of the unit itself, padlock it and display the
appropriate warning sign.
Refrigerant
The intervention of the safety valve and the consequent expulsion
of the gas refrigerant may cause injuries and intoxication.
Always wear suitable clothing including protective gloves and
eyeglasses for operations inside the danger zone.
Should the refrigerant leak please refer to the refrigerant “Safety
sheet”.
Contact between open ames or heat sources with the refrigerant
or the heating of the gas circuit under pressure (e.g. during welding
operations) may cause explosions or res.
Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding
must be carried out with the system o.
Hydraulic parts
Defects in tubing, the attachments or the removal parts may cause
a leak or water projection with the consequent damages to people,
things or shortcircuit the unit.
