3 - POSITIONING

3.1 PRELIMINARY INFORMATION

Operate in compliance with safety regulations in force. For detailed information (dimensions, weight, technical

characteristics etc.) please refer to the TECHNICAL INFORMATION section.

Use single protection devices : gloves, glasses ecc.

During positioning consider these elements :

 technical spaces required for the machine and system  place where the machine will be installed  electrical connections  water connections  air / aeraulic ducts

Do not considerer these elements could decrease performances and operational life of the unit.

3.2 FUNCTIONAL SPACES

Functional spaces are designed to:

 guarantee good unit operation  Carry out maintenance operations  protect authorized operators and exposed people

Respect all functional spaces indicated in the TECHNICAL INFORMATION section.

Double all functional spaces if two or more unit are aligned.

3.3 POSITIONING

Units are designed to be installed:

 EXTERNAL  in fixed positions.

Limit vibration transmission:

 use antivibration devices on unit bearing/supporting

points;

 install flexible joints on the hydraulic.

Installation standards:

 Safe accessible position;  avoid flood-prone places;  verify unit weight and bearing point capacity;  verify that all bearing points are aligned and leveled;  install the unit raised from the ground;  consider the maximum possible snow level

A correct circulation of the air is indispensible to guarantee the good working order of the machine.

Avoid therefore:

 obstacles to the airflow;  exchange difficulties;

 leaves or other foreign bodies that can obstruct the

exchange batteries;

 winds that hinder or favour the airflow;  heat or pollution sources close to the unit (chimneys,

extractors etc);

 stratification (cold air that stagnates at the bottom);  recirculation (expelled air that is sucked in again);  positioning below the level of the threshold, close to very

high walls, attics or in angles that could give rise to stratification or recirculation phenomenons.

Ignoring the previous indications could:

 energy efficiency decrease;  blocks due to HIGH PRESSURE (in summer) or LOW

PRESSURE (in winter).

3.4 FRESH AIR PROBE

The external probe allows to automatically change the unit setpoint according to the external enthalpy (temperature + humidity).

In this way is not possible to optimize the unit energy efficiency .

In the winter operating also the defrosting times are optimized. POSITIONING

The sensor must not be influenced by factors that can cause a false reading (for example direct sun rays, air expelled by the fan or other sources, contact with the unit structure or other heat sources, accumulation of snow/ice).

Example for the positioning of the external probe:

 A attic  B Underneath a terrace  C If attached to external wall provide a small roof

framework

4 - WATER CONNECTIONS

4.1 PRELIMINARY INFORMATION

Selection and installation of system components must be carry out by installer.

Following you will find some indications to integrate with what is provided by the local regulations in force and by the good technical laws.

4.2 COMPONENTS

CUT-OFF VALVES :

 installed at inlet and outlet (both on the water technique

circuit as well as that of the hot domestic water) allow maintenance operations without having to empty the system .

THERMOMETERS AND MANOMETERS :

 installed at entry and exit of the main elements facilitate

inspection and maintenance.

AN AIR BLEED VALVE :

 installed in all of the highest points of the system allowing

the venting of the circuits air..

DRAINAGE TAPS :

 installed in the lowest points of the system to allow

bleeding.

EXPANSION TANK :

 It keeps a correct system pressure when the water

temperature changes. It must be dimensioned as a function of water content.

WATER FILTER :

 if not present on-board the machine, must be installed

immediately in the water input of the unit, in a position that is easily accessible for cleaning.

 The filter never should be removed, this operation

invalidates the guaranty

SUPPORTI :

 The hydraulic pipes weight mustn’t burden on the unit

connections ..

FLOW SWITCH

 The flow switch must be present as a component of the

system

4.4 WATER QUALITY

The water quality can be checked by qualified personnel. Water with inadequate characteristics can cause:

 pressure drop increase  energy efficiency decrease  corrosive symptom increase

Water quality: acceptable values

4.5 RISK OF FREEZE

If the unit or the relative water connections can be subject to temperatures close to 0°C adopt measures for prevent risk of freeze.

For example:

 Mix water with ethylene glycol  Safeguard the pipes with heating cables placed under the

insulation

 Empty the system in cases of long non-use and check that:

 there are no closed taps present that could trap water

even after emptying

 there are no low points in which water can stagnate

even after emptying; carry out any blowing required .

4.6 ANTI-FREEZE SOLUTION

4.3 OPERATION SEQUENCE

Before connecting the unit, carefully wash the system by filling it and emptying it several times with clean water.

Ignoring this operation will lead to several filter cleaning interventions and at worst cases can cause damages to the exchangers and the other parts.

Execute leakage test before isolate the pipes. To avoid heat dispersions and formation of condensate isolate

all the pipes. Leave various point of service free (wells, ventholes etc ).

Consider that the use of anti-freeze solution determines an increase in a pressure drop.

Make sure that the glycol type utilized is inhibited (not corrosive) and compatible with the hydraulic circuit components (pump 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

necessaryprecautions (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.

4.11 HYDROPACK

OPTIONAL PUMPING STATION Available in the versions:

 Single pump  Double pump

in this configuration one pump acts as backup of the other. The microprocessor automatically balances the operating hours of both the pumps and, in case of failure, the unit signals the lockout of the pump out of use.

 Hydropack with 2 pumps

the pump operating acts in parallel. Thanks to this modular structure, the water flow-rate can be automatically reduced if the temperature increases over the operating limit. This device is very useful during starts-up, weekend pauses, and after a long period of inactivity. When the water temperature of the hydronic circuit is very high, possible blocks for overcharging are avoided, as well as the consequent interventions of specialized personnel for the assisted start-up. In case of failure of one pump, the unit continues to operate guaranteeing the 60% of the

nominal flow-rate. INERTIAL STORAGE TANK It is available in the standard version and in the primary/

secondary version to respond to different types of systems.

4.11 FREE-COOLING - OPTION

When the temperature of the fresh air is lower than the temperature of the return water of the system, the free-cooling version lets you recover cold from the external environment, reducing the work of the compressors all the way down to nothing.

USE OF ANTI-FREEZE SOLUTIONS The heat carrier used in the systems that include a Free-Cooling devi-

ce require a glycol solution (usually an ethylene type). This substance is required because the Free-Cooling units are intended to be installed where the temperature can drop to very low levels during certain times of the year. The percentage of glycol in the solution depends on the low temperatures that can be expected in the place of installation. Therefore, this parameter is at the discretion of the system designer.

Summer

 cooling of the solution is ensured by the refrigerating cycle with

operation of the compressors (C) as in a traditional chiller ;

 the Free-Cooling (Bh) coils are not involved.

SUMMER

Intermediate season The energy savings variable between 0 and 100%, based on the tem-

perature difference between fresh air and the system request. If the unit detects that the fresh air temperature (Ae) is suitable:

1. it inverts the position of the 3-way valve (V3), forcing the

solution to travel through the Free-Cooling coils (Bh) before reaching the evaporator (Ev);

2. it sets the fans (Fa) at maximum speed to obtain maximum

cooling of the solution from the fresh air;

3. the solution thus undergoes an initial cooling which is free and

natural;

valve VL cock on the liquid line Vm cock on the supply line Wi water inlet Wo water outlet

4. the remaining cooling is provided by the refrigeration cycle, with compressors in stepped operation (power absorbed proportional to the degree of stepping);

If the temperature of fresh air increases, the microprocessor will automatically revert operation to summer mode, ensuring the same conditions requested by the user.

INTERMEDIATE SEASON

Winter The three way valve (V3) is in the same position as in the previous

case;

 the temperature of the fresh brings the solution at the outlet of

the Free-Cooling coils (Bh) to the temperature required for use;

 the microprocessor control completely deactivates all com-

pressors (C), providing all cooling power at no cost, as opposed to standard units;

 if the difference between the temperature of the fresh air (Ae)

and that required for use is such that the temperature of the solution at the outlet of the Free-Cooling coils (Bh) drops below the set point required for use (which does not compromise unit safety, because of the glycol in the solution), the microprocessor modulates fan speed (Fa), turning them off if necessary. When the fans are off, if the temperature (Wo) continues to drop, the 3-way valve (V3) positions itself as in summer operation, changing to digital and allowing the set point to be maintained.

4.12 ENERGY RECOVERY - OPTION

Partial energy recovery The use of a desuperheater makes it possible to recover, free

of charge, the heat that would otherwise be dispersed in the environment. The partial heat recovery is composed of shell and tube heat exchangers suitable for recovery of 25% of the heat power dispersed by the unit (cooling and electrical power of the compressors). If the temperature of the water to be heated is relatively low, it is advisable to insert in the plumbing circuit an adjustment valve to keep the recovery inlet temperature greater than 35°C to prevent condensation.

3) Cold request 50%, hot request 100% = circuit active in

cold+recovery (in this case the unit can provide only 50% of

the requested heat).

With the recovery active the condensing coil (Bc) is deactivated and condensation takes place in the total recovery (R).

With the recovery setpoint met, the condensing coil (Bc) is reactivated, to perform condensation, via the solenoid valves

(Vr=off and Vc=on). In this case the recovery (R) acts as a

simple desuperheater.

and large potentials. The production of hot water is always of lesser priority than the production of chilled water. The total heat recovery is composed of shell and tube heat exchangers suitable for recovery of 100% of the heat power dispersed by the unit (cooling and electrical power of the compressors). The unit with total recovery is capable of managing the recovery temperature with thermal adjustment integrated in the microprocessor with two steps. The adjustment of power is managed based on chilled water and may have the following instances:

1) Cold request 100%, hot request 0% = circuit active only cold,

2) Cold request 100%, hot request 100% = circuit active in

6.1 PRELIMINARY INFORMATION

The indicated operations should be done by qualified technician with specific training on the product.

Upon request, the service centres performing the start-up; the electrical, water connections and the other system works are by the installer.

Agree upon in advance the star-up data with the service centre.

6.2 PRELIMINARY CHECKS

Before checking, please verify the following :

 the unit should be installed properly and in conformity with

this manual.

 the electrical power supply line should be sectioned at the

beginning.

 The line sectionalizing device is open, locked and equip-

ped with the suitable warning

 make sure no tension is present

6.3 REFRIGERANT CIRCUIT

6.5 ELECTRICAL CIRCUIT

Verify that the unit is connected to the ground plant Check the conductors tightening: the vibrations caused by

handling and transport might cause loosing Feed the unit by closing the sectioning device, but leave it on

OFF. Check the tension and line frequency values which must be

within the limits : 400/3/50 +/- 10%

Control the unbalancing of the phases: it must be lower than 2% Example:

1. Check carefully the refrigerating circuit: the presence of oil

stains can mean leakage caused by transportation, movements or other).

2. Verify that the refrigerating circuit is in pressure: Using the

unit manometers , if present, or service manometers.

3. Make sure that all the service outlets are closed

with proper caps; if caps are not present a leak of refrigerant can be possible.

6.4 HYDRAULIC CIRCUIT

1. Before realizing the unit connection make sure that the hydraulic system has been cleaned up and the clearing water has been drained

2. Check that the water circuit has been filled and pressurized

3. Check that the shut-off valves in the circuit are in the "OPEN" position.

4. Check that there isn’t air in the circuit, if required,

evacuate it using the air bleed valve placed in the system high points.

5. When using antifreeze solutions, make sure the glycol percentage is suitable for the type of use envisaged.

The working out of the limits can cause irreversible damages and voids the warranty.

Check with amperometric pliers the operating of the compressor carter heating. Before proceeding with the startup, leave the unit powered with stopped compressors for some hours.

6 - START-UP

6.6 COMPRESSOR CRANKCASE RESISTANCES

Connect the oil resistances on the compressor crankcase at least 8 hours before the compressor is to be starter :

 at the first unit start-up  after each prolonged period of inactivity

1. Supply the resistances switching off the unit isolator

switch.

2. To make sure that hte resistances are working, check the

power input .

3. At start-up the compressor crank-case temperature on the

lower side must be higher at least of 10°C than the outside temperature.

Do not start the compressor with the crankcase oil below operating temperature.

6.7 VOLTAGES

Check that the air and water temperatures are included in the

operating limits. Refer to “Control” section for the indications

on the control system. Start-up the unit. With operating unit, i.e. in stable conditions and next to the

operating ones, check:

 supply voltage  total absorption of the unit  absorption of the single electric loads

6.8 REMOTE CONTROLS

 Check that the remote controls (ON-OFF etc) are

connected and, if necessary, enabled with the respective parameters as indicated in the ELECTRICAL CONNECTIONS section.

 Check that probes and optional components are

connected and enabled with the respective parameters (ELECTRICAL CONNECTIONS section and following pages)

6.9 EVAPORATOR WATER FLOW-RATE

Check that the difference 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 flow rate (L/h). The cooling power is shown in the table of the GENERAL

TECHNICAL DATA included in this manual, referred to specific 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 flow rate.  Measure the difference 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 .

6.10 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 OUT of standards.

In the event of compressor break, due to the 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.

6.11 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 different electric loads (compressors,

fans, pumps etc)

 Temperatures and flows of the different fluids (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.

6.12 CE 97/23 PED DIRECTIVE

97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well. Refer to local actuation norms : Briefly and as an example, see the following :

 COMPULSORY VERIFICATION OF THE FIRST

INSTALLATION:

only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)

 CERTIFICATION OF SETTING IN SERVICE:

for all the units

 PERIODICAL VERIFICATIONS:

to be executed with the frequency indicated by the Manufacturer (see the MAINTENANCE INSPECTIONS paragraph

Notes / interventions recommended to the owner

* European regulation 303/2008

Refer to the local actuation regulations; in short and just as an indication the regulation order as follow. Companies and technicians that effect interventions of installation, maintenance/repairs, leak control and recovery must be CERTIFIED as expected by the local regulations. The leak control must be effected with annual renewal.

43

8 - MAINTENANCE

Maintenance must be done by authorized centres or by qualified personnel The maintenance allows to:

 maintain the unit efficiency  reduce the deterioration speed to whom every equipment

is subject over time

 assemble information and data to understand the state of

the unit efficiency and avoid possible damages

8.2 INSPECTIONS FREQUENCY

The inspections should be carried out at least:

 Every year for only the cooling units  Every six months for the cooling and warming units

The frequency, however, depends on the use. In the event of frequent use it is recommended to plan inspections at close intervals:

 frequent use (continuous or very intermittent use, near

the operating limits, etc)

 critical use (service necessary).

8.3 UNIT BOOKLET

8.6 ELECTRIC FANS 8.1 GENERAL

Check :

 the fans and the relative protection gridsare well fixed  The fan bearings (evident by noise and anomalous

vibrations )

 the terminal protection covers are closed and the cable

holders are properly positioned

8.7 COIL

Contact with the exchanger fins 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 fins to avoid damages. As an alternative, an aspirator can be used to suck impurities from the air input side.

It’s advisable to create a unit booklet to take notes of the unit

interventions. In this way it will be easier to adequately note the various interventions and aid any troubleshooting. Report on the booklet:

 data  type of intervention effected  intervention description  carried out measures etc.

TENSIONS

After switching off the power, wait at least 5 minutes before accessing to the electrical panel or any other electrical component.

Check with a multimeter that there are no residual tensions

8.4 STRUCTURE

Check the condition of the parts making up the structure. Paint so as to eliminate or reduce oxidation at the points in the unit where this problem may occur. Check that the panelling is fastened correctly. Poor fastening may give rise to malfunctions and abnormal noise and vibration.

8.5 WATER FILTER

Check that no impurities prevent the correct passage of water.

Verify that the aluminum fins are not bent or damaged. In the event of damages, contact the authorized assistance center

and get the battery “ironed out” in order to restore the initial

condition for an optimal air flow

8.8 WATER 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 difference between the temperature of the supply water and the condensation temperature. If the difference is greater than 8 °C – 10 ° C it is advisable to clean the exchanger. The clearing must be effected :

 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 rince with water to inhibe the detergent

rests.

8 - MAINTENANCE

!

8.9 CIRCULATION PUMPS

Verify :

 no leaks  Bearing status (anomalies are highlighted by abnormal

noise and vibration)

 The closing of the terminals cover and the correct

positioning of the cable glands.

8.10 PUT A REST

If a long period of inactivity is foreseen:

 Turn off the power

to avoid electrical risks or damages by lightning strikes

 drain the water

to avoid the risk of frost

 Protect from air exchangers and plant

To prevent any oxidation and fouling

1. evacuate the system

2. evacuate the exchanger

Use all the cocks presents

3. Use compressed air to blow the exchanger

4. dry completely the exchanger by an hot air jet

for greater safety fill the exchanger with glycoled solution

5. protect the exchanger from the air

6. Remove the drain plugs to the pumps

Before starting a washing the plant. It’s recommended that the starting-up after the stopping

10 - RESIDUAL RISKS

General

In this section the most common situations are signalled. As these cannot be controlled by the manufacturer these 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 fall 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 gas refrigerant leak please refer to the refrigerant "Safety sheet".

Installation An incorrect installation of the unit could cause water leaks, condensate

accumulation, leaking of the refrigerant, electric shock, bad functioning or damage to the unit itself.

Check that the installation has been implemented by qualified 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 inflammable gas and the accumulation of this gas in the area surrounding the area occur could cause explosions or fires.

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 cause the fall or the tipping of the unit with the 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-qualified

personnel may cause damge to persons, things or the unit itself. Always contact the qualified assistance centre. Failing to close the unit panels or failure to check the correct tightening

of all of the panelling fixing screws may cause damage to persons, things or the unit itself.

Periodically check that all of the panels are correctly closed and fixed. If there is a fire 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 fires.

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 fixing of the electric components cover may favour the entry of dust, water etc inside and may consequently can electric shocks, damage to the unit or fires.

Always fix 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 shield.

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 shield.

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 suitable sign. Contact with the fans can cause incurie. 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 gas refrigerant leak please refer to the refrigerant "Safety sheet".

Contact between open flames or heat sources with the refrigerant or the heating of the gas circuit under pressure (e.g. during welding operations) may cause explosions or fires.

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 off. Hydraulic parts Defects in tubing, the attachments or the cut-off parts may cause a leak

or water projection with the consequent damages to peopl, things or shortcircuit the unit.

Data referred to the following conditions:

- internal exchanger water = 12/7°C

- air at rest

Caution: Air conditions which are at rest are dened as the absence of air owing towards the unit. Weak winds can induce air to ow through the exchanger and air-levels which can cause a reduction in the operating range. In the presence of predominant winds it is necessary to use suitable windbreak barriers.

N.B. To ensure the correct maintenance (no operation) with outdoor air temperatures less than -10°C, the Standard unit (no FREE-COOLING conguration) must be equipped with the “Electrical panel anti-freeze protection” option and continue to be supplied with power. The hydraulic circuit must be lled with an adequate percentage of anti-

freeze. In these conditions, the minimum outdoor air temperature which is permitted depends on the model of the “Electrical panel anti-freeze protection” option which has been chosen, up to a limit value of -39°C. The operating mode can also be extended up to an outdoor air temperature of –25°C, but only in the FREE-COOLING conguration which is complete with an “Electrical panel anti-freeze protection” option of an adequate size. The operating mode can be further extended to external air temperatures of 39°C. Only in the full FREE-COOLING conguration of the ‘Device to reduce consumption of external section fans operating at variable speed (phase cut)’ and ‘Electrical panel antifreeze protection’ of an adequate size. In the Standard unit (no FREE-COOLING conguration) with an empty hydraulic circuit and without a power supply, correct maintenance (not operating) is possible up to a outdoor air temperature of -20°C.

Data referred to the following conditions: internal exchanger water = 12/7°C air at rest

Caution: Air conditions which are at rest are dened as the absence of air owing towards the unit. Weak winds can induce air to ow through the exchanger and air-levels which can cause a reduction in the operating range. In the presence of predominant winds it is necessary to use suitable windbreak barriers. N.B. To ensure the correct maintenance (no operation) with outdoor air temperatures less than -10°C, the Standard unit (no FREE-COOLING conguration) must be equipped with the “Electrical panel anti-freeze protection” option and continue to be supplied with power. The hydraulic circuit must be lled with an adequate percentage of antifreeze. In these conditions, the minimum outdoor air temperature which is permitted depends on the model of the “Electrical panel anti-freeze protection” option which has been chosen, up to a limit value of -39°C.

1. Max. inlet air temperature - Unit at full load

2. Max. inlet air temperature - Unit at part load

3. Min. inlet air temperature - Unit at full load and outdoor air at rest

4. Min. inlet air temperature - Unit at part load and outdoor air at rest

The operating mode can also be extended up to an outdoor air temperature of –25°C, but only in the FREE-COOLING conguration which is complete with an “Electrical panel anti-freeze protection” option of an adequate size. The operating mode can also be extended up to an external air temperature of –39°C, but only in the FREE-COOLING conguration which is complete with the ‘Electrical panel anti-freeze protection‘ option of an adequate size. In the Standard unit (no FREE-COOLING conguration) with an empty hydraulic circuit and without a power supply, correct maintenance (not operating) is possible up to a outdoor air temperature of -20°C.

Sound levels refer to full load units, in test nominal conditions. The sound pressure level refers to 1 m. from the unit outer surface operating in open eld. Measures according to UNI EN ISO 9614-2 regulations, with respect to the EUROVENT 8/1 certication.

Data referred to the following conditions: internal exchanger water = 12/7°C outdoor air temperature 35°C

Internal exchanger pressure drops

The pressure drops on the water side are calculated by considering an average water temperature at 7°℃

Q = water ow rate (l/s) DP = pressure drop [kPa]

Sound

pressure

level

The water ow rate must be calculated with the following formula

Q [l/s] = kWf / (4,186 x DT)

kWf = Cooling capacity in kW DT = Temperature dierence between inlet / outlet water

To the internal exchanger pressure drops must be added the pressure drops of the mechanical steel mesh strainer that must be placed on the water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option. (See the HYDRONIC ASSEMBLY ACCESSORIES). If the mechanical strainer is selected and installed by the Customer, it is forbidden the use of lters with the mesh pitch higher than 1,6 mm, because they can cause a bad unit operation and also its serious damaging.
