11. START-UP
11.1 FIRST START-UP MODE
In order to activate the warranty conditions provided
by the current regulations it is mandatory to request
the service of first ignition by an technical center.
A2B Accorroni E.G. LTD authorized by completing
the form shown on page 39.
The form must be sent by e-mail at the address
postvendita@accorroni.it
11.2 FIRST STARTING CHECKS
Before proceeding with commissioning
of the appliance you must make sure that:
- safety conditions and all requirements
reported in this manual have been respected;
- the attachment to the supporting surface is stable
and the zones of respect are free from any obstacle
or material that prevents easy access to the device;
- the hydraulic and electrical connections, with
particular attention to grounding,
have been executed correctly;
- interception, loading and unloading devices
and vent of the system are in the correct position
operating conditions and are been adequately
controlled.
WARNING! Starting the appliance,
in conditions of non-compliance with
prescriptions of this manual and / or of the
current safety regulations and plant engineering,
involves the forfeiture of the warranty conditions.
11.3 START-UP
Starting the appliance and selecting it of the
operating mode can be executed by acting directly
on the keyboard of the microprocessor with the
"SUN" button.
Hold for at least 2/3 seconds, at release the LED
with the sun indication will start to flash (compressor
count).
After a few minutes the LED will become solid, e
the machine will start working, heating up
the technical water of the indoor unit up to
SET-POINT temperature. At this point the
machine goes to full capacity and will carry out all
the on and off cycles in a manner automatic and
autonomous.
After starting the appliance, check the correct
operation of the plant, with particular attention to
the following:
- the water pump must not emit abnormal noise,
because this situation indicates that the air is not
been properly purged or that water flow is not
sufficient (possible obstructions, blockages or
disbursements adjustment of the devices on the
system);
- the voltage measured in the terminals of power
supply must be included in the 210-240 Volt
range for models with single phase power
supply. Lower values indicate a voltage drop in
the line electric 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 appliance must be
between 3 ° C and 8 ° C; values less than 3
° C indicate an excessive water flow,
vice versa the flow rate will be too low with
values greater than 8 ° C;
- if the above conditions do not come realized,
turn off the machine ed made corrective actions
to allow regular operation of the system.
12. REPAIR - REPLACEMENT COMPONENTS
For the intervention on the components listed
below and / or a replacement is required for their
replacement technical competence, for which it
is recommended always contact a Service
Center Authorized technique. For security
purposes e quality is recommended to be used
for replacement of original components and
spare parts.
Always operate in rough conditions safety, in
compliance with current regulations in the field.
Before any intervention on the appliance,
remove on the main switch and then on the on-
board disconnector machine.
For any emptying operations e charged with
refrigerant gas, use is recommended of specific
recovery equipment of refrigerant, for the
purpose of preservation
environment.
12.1 REFRIGERANT CIRCUIT
For whatever reason it was necessary
repair of the cooling circuit, with
consequent contamination, as in the case
of burning of the electric windings of the
compressor or circuit failure with complete
emptying, it is always necessary to do what
follows:
