3. SAFETY ADVICE
To avoid any risk of accident during installation, commissioning or
maintenance, it is obligatory to take into consideration the following
specifications for the units: refrigerated circuits under pressure, refrigerant
presence, electrical voltage presence and implantation place.
Because of all of this, only qualified and experienced personnel can
perform maintenance tasks or unit repairs.
It is required to follow the recommendations and instructions
in the maintenance brochures, the labels, and the specific
instructions.
It is necessary to comply with the norms and regulations
in effect. It is recommended to consult the competent
authorities regarding the applicable regulations for users
of units or components under pressure. The characteristics
of these units or components are included on the plates of
characteristics or in the regulatory documentation provided
with the product.
In case of a leak:
- Toxicity: According to ASHRAE 34, R-410A belongs to the A1/A1 group,
i.e. with high safety both in the mix and also in the case of a leak.
- Although it is not toxic, in case of a leak to atmospheric pressure the
liquid phase evaporates. The resulting vapours are heavier than air
and can displace the technician local air. In case of an accidental
discharge in a closed enclosure, fans must be used to eliminate said
vapours.
- Although the R-410A is not flammable, when in contact with a flame
o hot spot it can decompose in fluorhydric acid HF and fluophosgene
COF2highly toxic and corrosive.
- To detect leaks, an electronic leak detector, an ultraviolet lamp or
soapy water must be used. Flame detectors do not help.
Important: Immediately repair any refrigerant leak, using
a recovery unit specific for R-410A that avoids a possible
mixture of refrigerants and/or oils.
The compressor and line surfaces can reach temperatures
above 100ºC causing burns to the body. In the same fashion,
under certain conditions these surfaces can reach very cold
temperatures that can cause freezing risks.
Use safety goggles and gloves on the job. Be careful with
sharp parts or elements in the unit.
V-220005
V-220004
Caution: Before intervening in the unit, verify that the main
power to the unit is cut off. An electric shock can cause
personal damage.
Refrigerant leaks:
A periodical check must be performed for refrigerant gas leaks as
per Regulation (CE) Nº517/2014 over certain greenhouse effect
fluoride gases. Please, consult the frequency of checks in chapter
of “Maintenance”.

7. TRANSPORT AND HANDLING
Centre of gravity coordinates
- Discharge via forklift truck:
The unit is designed to be transported safely by using a forklift truck.
The forks of the forklift truck must come in on the side of the unit,
ensuring that the centre of gravity of the unit remains within the forks,
because a misbalance in the transport may cause the unit to turn
over and fall from the forklift truck.
The recommended length for the forks will be bigger than the unit
width, so that the entire weight-bearing structure can be supported
on the forklift truck. This also prevents the possible introduction
of the truck’s fork into functional parts of the unit that may cause
damage to the unit.
The standards and recommendations of the forklift truck must also
be respected with regards to the maximum load, inclination of the
panel, elevation of the load for transport, and, in particular, the
maximum speed.
Transport
The unit must be handled with care to avoid transport damage. Thus
we recommend:
- Do not dispose of the transport supports or the packaging materials
until the unit is in its final location.
- For transport in a container, one must be selected that has an easy
load and unload to the installation location.
Discharging of the unit
The unit can be discharged using:
- Forklift truck.
- Crane with a rocker arm and cloth slings.
Any handling of the unit by other means or by gripping points different
from those described here may be dangerous for both the unit and
the personnel who are carrying out the discharging or transport work.
Always check the weight of the set and verify that the discharging
method used is approved for handling that weight.
Note: please see the weight and the gravity centre coordinates
of each model stated in the following section.
Placement on site
Once the unit is discharged, it must be freed from the transport supports
so that the inserts available for the silent-blocks can be accessed. Each
support is fixed to the crossbar using 2 M4 screws.
M4 screws for fixing the support Mounting hole
- Discharge via crane:
A rocker arm, as well as approved cloth slings, both suitable for the
dimensions and weight of the unit, must be used in order to carry out
the work safely and without causing damage to the units or to workers.
These slings will be hooked
to the two mounting holes
located on each crossbar. Make
sure that the unit is protected
from contact with the hooks to
prevent damage to the housing.
The unit must be lifted and fixed with care, with maximum
inclination of 15º, since it could harm its operation. Do not
raise by points outside of those specified here.

Location designation
Before moving the unit, it must be checked that all panels are fastened
in place. Lift and lower with care.
When choosing the location, whatever may be the selected fashion, the
following precautions have to be taken into consideration:
- It is mandatory to comply with norm EN 378-3 on Safety and
Environmental Requirements. Part 3: "In situ" installation and
protection to people.
- The area where the unit will be located must be perfectly accessible for
cleaning and maintenance operations (check minimum free space for
maintenance). Leave enough space for air circulation around the unit.
- Check that the unit is perfectly levelled.
- It is necessary to check that the surface of the floor or the structure
supports the weight of the unit (please, consult the weight of the unit
in the section “Anchorage for silent-blocks”).
- Foresee appropriate damping devices in all the installation so that
noise and vibration transmission is avoided (refer to the “Anchorage
for silent-blocks”).
In the event of assembling directly on silent-blocks to the ground,
it is recommended that a template of the unit’s footprint with the
anchoring points of the silent-blocks be made.
8. LOCATION AND ASSEMBLING
With the help of the crane or the forklift truck, the unit will be raised
to a sufficient height that the silent-blocks can be screwed into its
base. The 4 silent-blocks must remain oblique and the interiors
perpendicular to the unit.
M10 metric threads have been provided for their placement in the
supports indicated in the following section “Anchorage for silent-
blocks”. A hex key 17 or Allen
wrench 8 will be used for this
operation based on the type
of screw used.
This image shows how the
silent-block option that can
be supplied for this unit is
fixed to the unit.
Since it is an unit designed to work indoors, some specific installation
norms must be followed:
- Ensure that the location of the supply and return grilles does not
generate air recirculation.
- Check that there are no obstructions in the air supply and return grille
slats due to being tightly closed.

Sound level
These units have been designed to operate with a low sound level.
In any case, in the design of the installation, it must be taken into
consideration: the outdoor environment for the acoustic radiation, the
type of building for the noise transmitted in the air and the solid elements
for the vibration transmission.
To reduce the transmissions through solid matter to the maximum, we
recommend installing damping devices between the floor or structure
and the frame of the unit and flexible connections in the hydraulic tubes.
If necessary, an acoustic technician must commission a study.
Sound pressure level
Measurement conditions: in a clear field, measured at a distance of 10
metres, directivity 2 and at 1,5 metres from the ground.
Note: The sound pressure level depends on the installation conditions and, as
such, is only indicated as a guide. Values obtained according to standard ISO 3744.
Unit sound power level
Measurement conditions: ducted discharge and return. For nominal
operating conditions EN 14511 – COOLING and HEATING modes.
Acoustic power reference: 10E-12 W, tolerance of ±2 dB (partial charge
of ±4 dB).
Note: The unit has acoustic insulating cover for compressor (Low Noise version).

NOTE: Under no circumstance should the unit be started without having read the brochure completely.
30PA/PH electronic control
The 30PA/PH control l is basically comprised of a PC SMALL control
board, a pGD1 graphic terminal, a TCO user terminal (optional for
remote control) and sensors.
In order to establish the unit's electric power supply (cable inlet,
calculation of the lead section, protections etc.), refer to:
- The information supplied in this document (table of technical
characteristics).
- Data plate.
- The wiring diagram and the legend supplied with the unit.
- The electronic control brochure which is supplied with the unit.
- The regulations and norms in force which regulate the installation of
air-conditioning units and electric receivers.
The electric power supply of the unit must be sized in accordance with
the maximum power input by the unit taking into account all the options
it features (if necessary, refer to the technical brochure).
Verify that electrical power corresponds to the one on the data plate
and that the voltage remains constant.
Check that the electrical connections are correct and tight
(an electrical diagram is included with each unit, along with
its legend).
Note: All connections in the site are the responsibility of the
installer. These connections are always made as per the
current regulation.
To prevent electrical shocks, make all electrical connections
before energizing the unit. Check that the automatic switch
is closed. Omitting this can cause personal damage. Make
the ground connection before any other electrical connection.

Checks in the centrifugal fan:
STD version
- Before commissioning, check the blade rotation direction and that
the axis turns without strokes nor vibrations
- Once running, check the operation conditions: pressures, flows and
consumptions.
- The coupling of characteristic curves of the fan and the room is
very important, so that the flows and pressures provided to the duct
network are as required.
- In case they are not aligned, remove the pulley screws, remove the
pulley and, after removing the taper pin, it can be slid over the axle
(this action can be performed both in the motor as well as in the fan).
- After fixing the pulleys on the same plane, the belt tension is made
by tightening the tensor screw.
- The belt tension must be checked after 24 hours of motor operation.
Attention: Before performing these operations, it is necessary to verify
that the unit is disconnected from mains.

Air ducts connections
For units designed for installation indoors with ducted supply and
return in the outdoor circuit, it is advisable to have the following
recommendations:
- Curves in the fan discharge supply must be avoided. It is
recommendable to have a straight section of duct measuring
approximately 1 metre. If it is not possible, they must be as smooth
as possible, using indoor deflectors when the duct is of large
dimensions.
- When making the ducts, direction sharp changes must be avoided
since they can generate occasional pressure drops, which affect
the available pressure and the flow. The location of discharge
and aspiration grilles must be studied carefully to avoid the air
recirculation and the transmission and generation of noises to the
interior.
- No matter the type of ducts type to use, these must be insulated and
must not be composed of materials that propagate fire nor expel toxic
gases in the event of a fire. The internal surfaces must be smooth
and should not pollute the air that circulates within them. In any case,
the effective legislation about this issue must be respected.
- Flexible connections must be made between the ducts and the unit
that avoid the noise and vibration transmission.
Flexible connections
Optionally, these units can be sent with flexible connections for supply
and return air.
In case of asking together for flexible connections and damper for
condensation pressure control (optional for version STD), discharge
flexible ducts are attached to the above mentioned damper.
If it is removed the damper for installation on duct, it is necessary to
maintain the frame for reconnecting the flexible connections.

Minimum installation volume
The electronic control for these units incorporates an auto-adaptive
control for the compressor operating time based on the time set for
anti-short-cycle.
This control reduces the number of times the compressor is started
up and permanently adjusts the system's thermal inertia, favouring
the reduction of the minimum volume of water in the installation. The
size of the buffer tank can also be decreased since the unit will be
stopped for less time.
Where:

V2Final volume of 1kg of water (at water temp. with the machine at normal speed)
PfFinal network pressure (safety valve pressure in bars + 1)
PiInitial network pressure (absolute filling pressure of the installation in bars)
Note: If the hydraulic circuit has a buffer tank, its volume must be taken
into account for this calculation.

for the majority of refrigeration applications (group with fan-coil units).
Note: The buffer tank is indispensable in installations that operate with a
reduced volume of water (group with an air handling unit) or for industrial
processes. For applications with a heat pump, it is recommended that
the buffer tank be used in order to maintain a stable temperature during
the defrosting cycles.

+ Good resistance under normal conditions.
0 There may be corrosion problems, especially if other factors intervene.
- Not advisable.
Note: For open-circuit installations, if it is not possible to
maintain the water conditions within the values indicated
in the previous table, it will be necessary to install an
exchanger that separates the unit's circuit from the water
circuit to be treated by using materials compatible with these
characteristics, whether stainless steel or titanium.
The units' hydraulic circuits are made of copper pipes. The exchanger
plates are made of AISI-316 stainless steel, and the material used for
soldering the plates is copper.
The following table indicates corrosion behaviour for copper and the
AISI-316 stainless steel with regard to water with different compositions.
Values outside these ranges can cause corrosion problems in the
hydraulic circuit and in particular in the plate exchangers.
It is recommended that the water filling the hydraulic circuits be filtered
and treated, if necessary.

- Check the pH obtained with pH paper strips or a pH metre.
- Place a label in a visible place that indicates:
* the presence of anti-freeze in the installation,
* the name of the product and the supplier,
* the dosage and the pH as of the time the unit is started up.
If more amount is needed, it must be exactly the same mixture as
the product initially used.
The following table and curves feature the minimum glycol percentages
required for the installation in accordance with the freezing point.
The pumps that incorporate the 30PAC/PHC units can work with any
concentration of mono-ethylene glycol, albeit with a reduction in the
available pressure due to the variation of water flow. The pump must
be changed for mono-propylene glycol (upon request).

Installation hydraulic diagram
The design of the hydraulic circuit must observe the operating conditions
(flows - pressure drops).
- The direction of water circulation
must be observed as indicated on
the stickers on the unit.
In this case the installer must set up the complete hydraulic circuit
with all the components: thermal buffer tank, motorised pump group,
expansion vessel, safety, regulation, cut-off and draining valves, air
bleeder valve, etc.
It is also necessary to install a filter in the hydraulic power
supply to the unit in order to prevent clogging of the plate
exchanger. Non-compliance with this recommendation can
cause reduced fl ow which can lead to freezing and breaking
of the exchanger.
- The diameters of the unit hydraulic connections can be referred in
the tables of “Technical characteristic” .
- It is advisable to use flexible hoses for connecting the piping to the
unit in order to reduce the transmission of vibrations to the building
to the greatest degree. It is mandatory to assemble hoses if the unit
is installed over shock absorbers. Optionally, a flexible hydraulic
connections kit can be supplied.
- The pipe layouts must be set out with the lowest possible number
of bends to minimise pressure drops. The pipes must be correctly
supported to prevent exerting excessive force on the unit connections.
- Before insulating the tubes and charging the system perform a
preliminary check to verify that there are no drops in the installation.
- The pipes must be carefully insulated to prevent leaks and
condensation. Ensure that the material used is steam barrier type.
Otherwise, cover the insulation using appropriate protection.
- The water must be analysed and the circuit must be set out according
to the results. If necessary, an expert in water treatment must be
consulted (see section on corrosion behaviour).
- In installations to open circuits, if it is not possible to maintain
the water conditions within the values indicated in the corrosion
behaviour table featured, it will be necessary to install an
exchanger that separates the unit circuit from the circuit of the
water circuit to be dealt with by using materials compatible with
these characteristics, whether stainless steel or titanium.
- Plan the anti-freeze protection for the installation when the outdoor
temperature is low: water with anti-freeze, thermal insulation of the
hydraulic circuit, electrical heaters in the hydraulic circuit, draining
from the installation when the unit does not work, etc.
Both at the inlet and the outlet of the unit, install thermal pressure
gauges which enable supervising the operation of the installation,
or at least plan the installation of these.
Note: optionally, a kit can be supplied with :
- A stainless steel mesh filter (500 microns).
- Cut-off and water regulation valves.
- Flexible hydraulic connections of 500 mm.

• 30PAC/PHC version (circulation pump included)
These units include a motorised pump group made up of: centrifugal
circulation pump, closed expansion vessel, safety valve with a tare
value of 4 bar, draining valve, and automatic air bleeder valve (model
160HEE and 180HEE).
A kit with a stainless steel mesh filter (500 microns) is also supplied
for installation by the installer. It is also necessary to install this
filter in the hydraulic power supply to the unit in order to prevent
clogging of the plate exchanger.

The installer must prepare the other accessories for completion of the
hydraulic circuit: thermal buffer tank, air bleeder valve (except models
160HEE and 180HEE), regulation, cut-off and draining valves, etc.
Both at the inlet and the outlet of the unit, install thermal pressure
gauges which enable supervising the operation of the installation,
or at least plan the installation of these.
Note: optionally, a kit can be supplied with :
- Cut-off and water regulation valves.
- Flexible hydraulic connections of 500 mm.

Note: These pumps can operate with glycol water (mono-ethylene
glycol), although with a reduction of the available pressure (due to the
flow variation with glycol water). The correction coefficients for operation
with glycol water can be referred to in the technical brochure for these
units (No. 10056).

Siphon installation norms
All water drain tubes must be provided with a siphon to avoid bad smell
and water spills.
• Pan in underpressure:
Water must be suctioned from the pan because of the depression
with respect to the motorfan assembly.
Perform the siphon assembly as per the scheme of the attached
starting diagram:
- For the correct siphon design, the "A" height must be at least twice
that of the underpressure (mm.w.c) where the condensate pan is
placed.
- Check that the condensate outlet is not clogged.
- The drain piping must be slightly sloped to ease circulation towards
the drain.
- The original diameter of the piping must be respected. No reduction
can be made.
- With outdoor temperatures which are lower than 0°C, the necessary
precautions must be taken to prevent the water in the drain ducts
from freezing.

To drainage
Check the watertightness of the connection.
Attention: With low outdoor temperatures, the electrical heater-based
anti-freeze protection option for the pan is recommended. Mandatory
when outdoor temperatures are below 3°C.
Condensate drain connection
In 30PA/PH/PAC/PHC units, the condensate drain pan includes a 3/4”
M bronze, bleeding trunk for draining condensates.
• Pan in overpressure:
It is installed to avoid the access through the drain piping of bad
smells.
