22.4
Draining the condensate water
The draining device to take out the condensate water from the chimney should not be altered in any
way and it must be kept free of obstructions.
22.5
Boiler water characteristics
In areas with water hardness of over 25-30 ºfH, 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 it is necessary to drain partially or totally the water of the installation very often, we recommend
filling it with treated water.
IMPORTANT NOTES
Improper handling of the boiler can lead to serious or even fatal failures for the appliance.
Therefore, it is strictly forbidden for the user of the boiler to enter the TECHNICAL parameters, which are
values that can directly affect the correct operation and destruction of the appliance. Only an authorized
DOMUSA TEKNIK
technical service can access it.
The user must ensure that the water pressure in the installation is correct, that is, a pressure of 1.5 bar.
If the pressure is less than 0.5 bar, an
E19
error code will appear on the display and an
E28
code will
appear if the pressure is greater than 2.5 bar.
The standard vents where the boiler is located (boiler room) must in no case be obstructed or partially
obstructed.
The maintenance of the boiler will be carried out in accordance with what is specified in this brochure.
The appliance should be visually inspected regularly for any leaks or malfunctions.
It is
MANDATORY
that maintenance operations be carried out by an approved professional from the
DOMUSA TEKNIK
network, at least once a year on the boiler and twice a year on the flue, according to
the standards in force.
