Electrical connection
The module electrical connections must be made by sufficiently qualified staff in strict compliance
with the sections below and with any electrical safety regulations applicable at time of installation.
DANGER
It must be ensured that the module is disconnected from the electrical supply before carrying
out any servicing inside the module and, particularly, on the electric terminal strips.
If the electrical supply is connected electrical contact could occur, causing serious damage
and/or death due to electrocution.
The module is designed for mains connection at 230 V - 50 Hz using its standard supplied cable.
Make sure that the electrical installation corresponds to the maximum power to be supplied, as
indicated on the module's specifications label. To replace the main fuse on the electronic card, use
2A fuses.
It is essential for the module to be grounded.
Make sure you have tightened the cables sufficiently. The module electrical
connections must be made in compliance with the applicable standards and regulations in the
place of installation
.

Start-up
In order for the
warranty to be valid
, the module must be started up by an official
DOMUSA
TEKNIK Technical Assistance Service
. Before the start-up process, the followings must be complied
with:
- The module must be connected to the mains.
- The installation must be filled with water (the pressure must be between 0.1 and 0.15 MPa (1 to
1.5 bar)).
- Check the flue is correctly installed.
- Check the gas supply is correctly installed.
- Drain the air from the module gas circuit, opening the gas installation shut-off valve and
slightly loosening the valve gas intake pressure port for a moment, as otherwise the air would
have to come out gradually through the burner.
- If the installation has flow and return valves, check they are open.
- If chronothermostat or remote control is available, set it to the desired temperature.
- It is essential to carry out a module combustion analysis, using a suitable analyser for this
purpose. The combustion analysis will be carried out in the collection of gas samples from the
gas outlet. If the analysis shows the combustion is outside the limits indicated in the
"Adjusting
the combustion"
section, adjust the module combustion.
To start up the module, follow the instructions in
“Switching on the module”
section.
