3.8 SYSTEM FILLING
AND EMPTYING
3.9 ELECTRICAL CONNECTIONS
General recommendations
Electrical safety of the appliance is only ensured when it is correctly
connected to an
efficien
t earthing system as spe
cifie
d by current safety
standards: earthing outlets, gas, water and central heating system pipes
are absolutely not suitable.
It is necessary to check this fundamental safety requirement; In case
of doubt, have an accurate inspection of the electrical system carried
out by professionally qua
lifie
d personnel, as the manufacturer is not
responsible for any damage caused by the lack of a earthing connection
in the system.
Have professionally qua
lifie
d personnel make sure the electrical system
is suitable for the maximum power absorbed by the appliance, as stated
on the plate, making sure in particular that the section of the system's
cables is suitable for the power absorbed by the appliance.
For the main power supply to the appliance, never use adapters, multiple
sockets and/or extension leads.
Th
e use of components involving use of electrical power requires some
fundamental rules to be observed such as:
- do not touch the appliance with wet and/or moist parts of the body
and/or barefoot;
- do not pull the electric cables;
- the appliance may not be used by children or unskilled individuals.
Danger! Before setting up the connections or any
operation on the electrical parts, always cut-o
ff
the
electrical supply and make sure it cannot be acciden-
tally re-connected.
Remove the indicated screws in order to access the
panel.
Note:
Th
e image shown in the following page refers to
ARES PRO 150. For all other models, the HSCP heat
adjuster is in line with BCM.
When all system connections have been completed, the
circuit can b
e fi
lled.
To
fi
ll the system, you must provide a
fi
lling valve on
the system's return.
ATTENTI
ON!
Do not mix the heating water with antifreeze or anti-
corrosion substances at incorrect concentrations!
This
may damage gaskets and cause noise to develop
during operation.
Alpha will not be held liable in case of damage
caused to people, animals or property due to failure
to observe the above.
Once all of the system connections have been made, it is possible to
fill the circuit.
To fill the system install a
temporary
filling loop and
pressurisation unit to the system return pipe, in conjunction with
a correctly sized expansion vessel/s. Never use a pressurisation
unit to fill the system.
The boiler is fitted with a drain point, as shown in Section 2.
1
This
must never be used to drain the complete system, as dirt contained
in the system may accumulate in the boiler, preventing smooth
operation. Accordingly, the system must be equipped with its own
drain point/s.
