as possible to ensure the highest service life.
The first heating must allow the evacuation of moisture
from concrete doors, it is necessary to avoid any heat
shock and adopt a rise in temperature as slow as
possible.
Do not hesitate to adopt the burner's burner maintenance
accessories to minimize structural vibration of the
burner assembly.
Unit monitoring
If the recommendations listed above (new installation
or renovation) have been followed, the unit monitoring
is limited to:
- Checking the amount of make-up water (fill water
make-up water volume < 3 times the unit
volume)
- Checking the pH level (stable or slightly increasing)
- Checking the total hardness (stable or slightly
decreasing)
We recommend monitoring these parameters two to
three times a year. Note: Monitoring the quantity of
make-up water is critical to the long life of the unit.
If any of these parameters deviates from the above
recommendations, refer to a water treatment specialist
to correct the problem.
Setting up a plate exchanger
If the recommendations listed above cannot be met, you
can set up a plate exchanger to separate the primary
system from the secondary system, which protects the
Electrical installation
Electrical connections must be made exclusively by
qualified personnel and all prevailing electrical
regulations must be scrupulously observed.
Make sure that the electrical power supply used for
connection conforms to the specifications indicated
on the rating plate and in this manual.
The unit must be correctly connected to an efficient
ground system in conformity to the prevailing norms
and checked and controlled for efficiency by qualified
personnel when in doubt.
Never confuse neutral wires with phase wires.
The unit must be hooked up to the electrical network
with a plug-socket connection that is such as to
boiler from undesirable effects.
prevent inversion of phase and neutral. Install a
master switch for the heating plant as requested by
existing legislation.
The entire electrical system, and all cable sections in
particular, must be adequate to deliver the maximum
absorbed power value indicated on the equipment's
rating plate and in this manual.
If the mains power cable is found to be defective, it
must be replaced only by qualified personnel.
Never stretch power supply cables and keep them
well away from sources of heat.
Maintenance
Maintenance must be performed by qualified
personnel regularly or at least once a year.
Prior to performing any maintenance operations,
switch off the power supply by using the main switch
and cut off the fuel supply as well.
Only parts indicated by the manufacturer in the
Spare Parts Catalogue may be replaced.
In order to avoid all types of health hazards,
suitable clothing and a protective mask must be
worn for work on or with components made of
synthetic silicon mineral fibers (ceramic and
glass fibers, insulation wool).
Malfunction
If the unit stops working and goes into lock-out and
does not resume operation after two or three
manual lock-out reset attempts, disconnect the
power supply, do not attempt to repair, and contact a
qualified specialist.
All repairs required must be performed exclusively
at a technical servicing and/or technician centre
authorized by the manufacturer using original spare
parts only. Failure to observe the above may
compromise the reliability and safety of the
equipment.
Any failure or damage resulting from improper use
or intentional damage will relieve the manufacturer
from any guarantee obligation.
