9. WARNINGS
9.1 QUALIFICATION OF THE INSTALLER
WARNING! It is foreseen by the current legislation on the
subject (law 5 March 1990 n. 46 and relative Implementing
Regulation) that the installation is carried out by a qualified
company to ensure, as well as the correct construction of the
plant, also the necessary checks before commissioning.
9.2 PRELIMINARY INFORMATION
Before starting the installation you need to make sure that
the planning and procurement phases have been completed
any necessary authorizations (ex: local authorities -
Municipality, etc.), in addition to the appropriate technical
checks (for example: acoustic impact assessment).
It is recommended in order to rely on a heating technician
qualified to guarantee the correct execution of the
aforementioned phases, whether optional or mandatory.
9.3 TRANSPORT AND HANDLING
The appliance is shipped on a wooden pallet, with protections
in cardboard and plastic material. The appliance can be
handled by suitably equipped personnel and with equipment
suitable for the weight of the product, such as trolley
lift or pallet truck, taking care to distribute on the supports
the weight, which is unbalanced towards the compressor
(attack side) water).
Any lifting using belts or ropes can be carried out, binding the
ropes to two sturdy metal tubes inserted in the crossbars under
the base of the machine.
Secure the ropes at the anchoring points of the pipes through
suitable safety catches or pins; protect by cardboard or other
suitable material the contact points between the ropes e
the appliance. Upon delivery, check that during transport not
any visible damage has occurred on the packaging and / or on
the unit. In the event of damage being found, display

9.5 GENERAL SYSTEM CHECKS
WARNING! Before filling the system, it is necessary make
sure the pipes do not contain material foreign, such as sand,
slag, rust flakes and whatever else may damage the
exchanger. It's good standard to wash the system by-passing
unit before filling it. Load the system, taking care of check
the opening of the interception valves and the closing the
system drain cock.
WARNING !
- Connect the indoor unit first and then
- the outdoor unit, fixing the pipes firmly.
- Make sure the drain is not loose.
- Ensure that the auxiliary pipes have been isolated.
- Make sure the drain flows properly.
- Fix the drain to the other pipes.
- Prevent the power cables from coming into contact
- with the pipes.
- Install check valves in the system to avoid
- that the water contained in the accumulation does not
circulate
- freely when it is not necessary, or when
- there is no consent from thermoregulation.
10. START-UP
Before proceeding with the commissioning of the appliance
you need to make sure that:
- the safety conditions and all the provisions listed in this
manual has been complied with;
- the fixing to the support surface is stable and the areas of
respect be free from any obstacles or materials that prevent
them easy access to the device;
- the hydraulic and electrical connections, with particular
attention to grounding, have been carried out correctly;
- interception, loading, unloading and venting devices
of the system are in the correct operating conditions and
have been adequately controlled.
WARNING! Starting the appliance in conditions failure to
comply with the provisions of this manual and / or current safety
regulations and plant, involves the forfeiture of the conditions of
warranty.
10.2 START-UP
Starting the appliance and selecting the mode of operation can
be performed by acting directly in the microprocessor keyboard
with the "SUN" button.
Press and hold for at least 2/3 seconds, when the LED is
released with the indication of the sun will start to flash (count
compressor).
After a few minutes the LED will become solid, and the machine
will enter in operation, heating the technical water of the indoor
unit up to SET-POINT temperature. At this point the machine
enters a regime and will carry out all on and off cycles in
automatic and autonomous manner.
After starting the appliance, check for correct operation
of the plant, with particular attention to the following:
- the water pump must not emit abnormal noise, as this
situation indicates that the air has not been properly purged or
that the water flow rate is not sufficient (possible obstructions,
blockages or supplies) adjustment of the devices on the
system);
- the voltage measured in the power supply terminals must
be included in the 210-240 Volt range for models with
single phase power supply. Lower values indicate one
voltage drop in the power line too high, with consequent
possible damage to the compressor, which can also occur for
voltages greater than those indicated above;
- the measured temperature difference between input and
output of the device it must be between 3 ° C and 8 ° C; values
less than 3 ° C indicate an excessive water flow, vice versa the
flow rate it will be too low with values greater than 8 ° C;
- if the above conditions are not fulfilled, switch off the machine
and make corrective actions to allow regular operation of the
system.
11. REPAIR - COMPONENT REPLACEMENT
For the intervention on the components listed below and / or for
theirs replacement requires a specific technical competence, for
which it is recommended to always contact an Assistance
Center Authorized technique.

refrigerator, resulting in contamination, as in the case of
burning of the electric windings of the compressor or failure
of the circuit with complete emptying, it is always necessary to
carry out as follows:
- replacement of the filter drier;
- circuit cleaning;
- drying and high vacuum;
- test of tightness and restoration of the charge.
