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 domestic hot water tank
The hot water tanks must be filled before filling the heating circuit. Open the flow of domestic hot
water to the hot water tank, and turn on a hot water tap in the installation. When the tap begins to
run freely, turn it off, as this means the hot water tank is full.
5.3
Filling 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 caps
(16)
and
(11)
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 HDX
boilers have a pressure sensor
(13)
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.
5.4
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.
5.5
Installation delivery
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.
