STARTING UP THE BOILER
5.1
Prior warnings
Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by
DOMUSA TEKNIK. For optimum functioning and conservation of the boiler, it should be serviced
annually.
Carefully read this instructions manual and keep it in a safe, easily-accessible place.
Before any servicing, disconnect the boiler from the mains and cut off the oil supply. Any
manipulation of the sealed parts of the boiler is prohibited.
DOMUSA TEKNIK will not be liable for any damages caused by failure to follow these instructions.
5.2
Filling the the heating circuit
To fill the heating circuit installation, open the fill valve
(20)
until a pressure of 1 - 1.5 bars appears
on the “
boiler pressure
” setting on the display. The circuit should be filled slowly and with the
automatic air bleed valve cap
(6)
loose, to let the air out of the installation. The air should also be
bled from the rest of the installation using the air bleed valves provided. When the installation has
been filled, close the fill valve.
Evolution Solar HFD
boilers have a pressure sensor
(9)
for controlling the pressure of the
installation. If the installation pressure drops below a minimum of 0.5 bar, the boiler will not switch
on and a low pressure alarm will appear on the display ("
AP
").
NOTE: Switching on the boiler with no water inside could result in serious damage.
5.3
Start-up
In order for the guarantee to be valid, the boiler must be started up by an
official DOMUSA TEKNIK
Technical Assistance Service.
Before beginning start-up, the following must be complied with:
- The boiler must be electrically connected to the mains.
- The installation must be filled with water (the manometer must indicate 1 - 1.5 bar).
- Fuel must be reaching the burner at a pressure of no more than 0.5 bar.
- The solar circuit must be filled up to the level socket.
5.4
Delivery of the installation
After the initial start-up, the Technical Assistance Service will explain to the user how the boiler
functions, making any observations they consider relevant.
The installer is responsible for clearly explaining to the user the functioning of any control or
regulation device forming part of the installation but not supplied with the boiler.
