• 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
4.3 OPERATION SEQUENCE
Before connecting the unit, carefully wash the system by
filling it and emptying it several times with clean water.
In the units equipped with hydraulic pipeworks use the
bypass.
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, vent-holes
etc )
4.4 WATER QUALITY
The water quality is determined by the following
factors, avoid therefore:
• Inorganic salts
• pH
• Biological load (seaweeds etc)
• Suspended solids
• Dissolved oxygen
Water with inadequate characteristics can cause:
• pressure drop increase
• energy efficiency decrease
• corrosive symptom increase
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
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).

4.10 PLUMBING ASSEMBLY
FOR LOOP WITH DISPOSABLE WATER
The plumbing assembly for systems with disposable water
(from well or groundwater) includes in addition to 1, 2 and 3
standard components :
1 2-way motorised modulating valve at the exchanger
outlet (the operation is linked to that of the
refrigeration circuit:modulating the valve opening by 010V signal the water content is reduced and the unit
operation values are maintained within the limits
allowed)
2 manually activated three-way valve for loop wash by-
pass (to allow washing of the pipes of the system and
protect the heat exchanger against fouling);
In summer operation, the device, complete with modulating
valve, makes it possible to maximize the thermal differential
of the water and hence to reduce the water flow rate.
In winter operation, modulation of the water flow rate allows
the unit to function with the water loop at high temperature. An
additional advantage of using this device is the extension of
the operating limits of the unit in summer and winter.

4.9 PLUMBING ASSEMBLY
FOR LOOP WITH VARIABLE
The plumbing assembly for the constant flow rate loop includes, in addition to 1, 2 and 3 standard components :
4 two-way motorize ON/OFF valve, operation is linked
to that of the refrigeration circuit: with the compressor
off the valve stays closed and as a result less water is
used
5 manually activated three-way valve for loop wash by-
pass (to allow washing of the pipes of the system and
protect the heat exchanger against fouling);
MAX. WORKING PRESSURE
• Standard unit = 700 kPa
• With ON/OFF valves = 700 kPa
• With manual valves = 700 kPa
• With modulating valve = 300 kPa
Aries effects and air bubbles can produce the overcoming and
cause water drops.

4.11 CONDENSATE DISCHARGE
The condensate must be dispersed to avoid damages
to persons and property .
• Unit discharge fitting : the connection must avoid the
transmission of mechanical stresses and must be
performed paying attention to avoid the damaging of
the unit discharge fitting .
• Make a trap that, eliminating the depression caused
by the fan, stops the return of gas from the
discharge pipe
• The ducting must have an appropriate slope to allow
the downflow
• Anchor the ducting with an appropriate number of
supports.
Otherwise are generated ducting failures and air
pockets that prevent the downflow.
• Insulate the ducting and the siphon to avoid
condensate drippings
• Connect the condensate discharge to a rainwater
drain.
• Do NOT use sewerage drains, so as to avoid the
return of odours if the water contained in the trap
evaporates
• Finally, check that the condensate will drain
correctly by pouring water into the tray stud
Calculation of the siphon height T = 2P
S = T/2
P is the pressure determinate by the fan in

5 - AERAULIC CONNECTIONS
5.1 GENERAL
Proper execution and sizing of air connections are essential
for ensuring correct operation of the unit and an acceptable
level of silence in the room.
When designing and creating ducts, consider PRESSURE
DROPS, FLOW RATE and AIR SPEED which need to be
compatible with the characteristics of the unit.
Special consideration needs to be made for pressure drops
that are greater than the unit's static pressure, which would
lead to a reduction in flow rate resulting in unit shutdown.
• the weight of the ducts must not be supported by the
connection flanges
• place anti-vibration joints between the ducts and the unit
• the connection to the flanges and between the various
sections of the ducts must ensure an airtight seal, preventing leakage in delivery and return which would compromise overall system efficiency.
• limit pressure drops by optimizing the path, the type and
number of curves and the branches
• use curves with a wide radius. Consider whether it might
be useful to equip them with deflectors (especially if the air
speed is high or if curves are tight )
For purposes of comfort, the following things need to be considered:
• air diffusers must be selected by checking the sound
power generated at nominal flow rate conditions
• the disconnections to the diffusers are to be made
using flexible elements
• the return grilles must be amply sized
APPLICATIONS AT HIGH DEGREE OF SILENCE
For applications that require a high degree of silence in the
system:
• In delivery and return, provide septum silencers, pre-
ferably inserted in sections of ducts located outside
the building. The septums must ensure the required
dampening with minimum pressure drops (ONLY
OUTDOOR UNITS – do not print note).
• Equip all curves with deflectors.
5.2 FEATURES FOR DUCTS FOR TREATED AIR
• The inner surface of the duct must be smooth and washa-
ble. It must not contaminate the air.
• Thermally insulate the ducts and the flanges so as to pre-
vent loss of energy and condensation build-up.
GRILLES OUTLETS DIFFUSERS
Proper distribution of air in the room is essential for ensuring
comfort levels.
In the selection and positioning of grilles, outlets and diffusers,
the following are to be avoided:
• excessive air speed
• formation of stagnant zones and layering
• entry of cold air into the room
• formation of localized currents (due to uneven air
distribution)
• excessive variations in ambient temperature in the
vertical and horizontal planes
• short circuiting of delivery air towards return air

9 - MAINTENANCE
9.1 GENERAL
Maintenance must be done by authorized centres or by
qualified personnel
The maintenance enables:
• 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
9.2 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 inspec-
tions at close intervals :
• frequent use (continuous or very intermittent use, near the
operating limits, etc)
• critical use (service necessary) .
9.3 MACHINE BOOKLET
It’s advisable to create a machine booklet to take notes of the
unit interventions.
In this way will be easier marker the various interventions and
will be e facilitate any troubleshooting.
Report on the booklet :
• data
• type of intervention effected
• intervention description
• Carried out measures etc ..
9.4 PUT A REST
• If a long period of inactivity is foreseen :
• put the unit in OFF
• wait for 1 minute, so that the water valves are in rest
position
• Turn of the power in order to avoid electrical risks or
damages by lightning strike
• avoid the risk of frosts (empty or add glycol in the plant
sections subjected to temperatures below zero , power
antifreeze resistances if are present )
It’s recommended that the starter after the period of detention
is made by a qualified technician, especially after seasonal
stops or seasonal switch.
When restarting, refer to the START-UP section .
Schedule technical assistance in advance to avoid hitches
and be able to use the installation when necessary.
9.5 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 paneling is fastened correctly. Poor fastening
may give rise to malfunctions and abnormal noise and
vibration .
9.6 PLEATED FILTERS
It is very important for the air treatment coil to be able to offer
maximum thermal exchange. Therefore, the unit must always
operate with the filters installed and clean.
Cleaning and replacement of filters are very important in terms
of health and hygiene.
Operation with clogged filters leads to a reduction in the air
flow rate, resulting in malfunctions and unit shutdowns. It may
even cause the unit to break down.
How often the filters need to be checked depends on the
quality of outdoor air, unit operating hours, dust and number
of persons in the rooms.
As a guideline, cleaning should ideally take place between
WEEKLY and MONTHLY. It is advisable to start with frequent
checks, and to adjust the frequency based on how much dirt
is discovered .
• Remove the closing doors
• Carefully extract the filter so that no dust reaches the
parts below
• Wash the filtering mattress in warm water with a
common detergent.
• Carefully rinse it under water while preventing to pour
water in the room
• Dry the filter
• Reinsert it to its seat
• Reassemble the closing doors
Old filters, washing residuals and residual parts must be
disposed of, according to the law in force .
26
Page 27
9 - MAINTENANCE
9.7 INTERNAL AIR COIL
Accidental contact with the fins of the exchanger may cause
small cuts. When performing the following steps, use
protective gloves.
The finned surfaces of the cooling coils and especially the
condensation collection trays are the places where micro-
organisms and moulds most easily flourish. It is therefore
very important to clean regularly with suitable detergents and
disinfect with appropriate products as necessary.
9.8 CONDENSATE DISCHARGE
Dust and deposits could cause obstructions .
In the tank can also proliferate microorganisms and mold.
Very important to provide for a periodic cleaning with
appropriate detergents and in case to a disinfection with
sanitizing products.
Clean the tank, pour some water into the tank and check
water flows normally.
9.9 DUCTING
Check the fixing screws and the operation of the anti-vibration
devices in order to prevent the transmission of vibrations in
the room .
9.13 WATER FILTER
Verify that there are no impurities which hinder the smooth
passage of water.
9.14 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
9.15 OIL COMPRESSOR ELECTRIC HEATERS
Regularly check the fixing status .
9.10 ELECTRICAL HEATING ELEMENTS
Regularly check the cleaning and the fixing status .
9.11 ELECTRIC FANS
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
9.12 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.

12 - RESIDUAL RISKS
12.1 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
12.2 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
12.3 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".
12.4 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 .
12.5 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.
12.6 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.
12.7 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
38
Page 39
12 - RESIDUAL RISKS
isolator on the attachment line of the unit itself, padlock it and
display the appropriate warning sign.
12.8 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.
12.9 Hydraulic parts
