INSTALLATION WHEN REPLACING ANOTHER APPARATUS
When solar boilers Series BDS are installed on systems being
old or to be renewed, make sure that
- Safety and control tools are available during installation, in
compliance with the relevant standards in force.
- The system is perfectly clean, free of muds and scales,
deaerated and that water seals are in good conditions.
- A proper treatment system is provided in the presence of
special feeding/reinstatement water. Please refer to the
values reported in the table beside here.
WATER CONNECTIONS
Solar boilers Series BDS can be connected to existing air
heaters, provided their thermal power is compatible and water
flow direction is maintained. They are especially suitable for
installation solar systems.
