To prevent any damage to people and property, the following safety indications must be taken into
account during the maintenance operations described in the following sections:
•
Before any servicing, disconnect the boiler from the mains.
•
Wear a protective mask (standard mask) when cleaning the suction turbine and the
protection grille to protect against the formation of airborne dust.
21.8 Draining the condensation water
Draining of condensation water from the flue should not be altered in any way and it must be kept free
of obstructions.
21.9 Boiler water characteristics
In areas with water hardness exceeding 25-30ºfH, treated water must be used in the heating
installation to avoid any scale deposits on the boiler. It should be noted that even a few millimetres of
scale will greatly reduce the boiler's heat conductivity, causing a major drop in performance.
Treated water must be used in the heating circuit in the following cases:
•
Very large circuits (containing a large amount of water).
•
Frequent filling of the installation.
If repeated partial or total draining of the installation is necessary, we recommend filling it with treated
water.
IMPORTANT NOTE:
- Improper handling of the boiler may cause serious or even fatal damage to the apparatus.
- The user must ensure that the water pressure of the installation is correct, that is, at a pressure
between 1 and 1.5 bar. If the pressure is below 0.5 bar, an error code
E-19 will appear on the
display and code E-28 if the pressure exceeds 2.5 bar.
- The standardised ventilations where the boiler is situated (boiler room) must not be obstructed or
partially obstructed under any circumstances.
- Boiler maintenance shall be carried out in accordance with the specifications in this manual. The
apparatus must be visually inspected regularly to detect any leak or malfunction.
