FILLING THE INSTALLATION
To fill the installation, open the fill valve
(13)
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
(4)
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
boilers have a pressure sensor
(10)
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 (

"
).
NOTE: Switching on the boiler with no water inside could result in serious damage.

DRAINING THE BOILER
The water is drained from the boiler by opening the air drain valve
(17)
inside the boiler (on the lower
right hand side on opening the door). Connect a flexible tube to this valve and run it to a drain. After
draining the boiler, close the valve again and remove the flexible tube.

SHUTTING DOWN THE BOILER
To switch off the boiler, place your finger on the power touch button
(22)
for 1 second. In
Off mode
,
while the boiler is plugged into the mains and connected to the fuel installation, its heating and DHW
functions will be switched off but the anti-frost protection and pump anti-block functions will remain
activated.
To shut down the boiler functioning completely, unplug it from the mains and cut off the fuel supply.

FIRST START-UP
For the
guarantee to be valid
, the boiler must be started up for the first time 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 (1 - 1.5 bar must be indicated on the digital display).
- Fuel must be reaching the burner at a pressure of no more than 0.5 bar.

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.
