1.2. Installation

The installation must be carried out by approved personnel only.
Observe local legislation and guidelines.
Flush the installation through before installing the vessel (never via the safety valve) and
check the installation for leaks whilst under pressure.
Fitting
• Expansion vessels with a capacity of between 8 and 25 litres are installed with the water
nipple (E) pointing up or down. (fig. 2)
appropriate. (fig. 7)
• Expansion vessels with a capacity of between 35 and 150 litres (9,2 - 39,6 GAL) are installed
standing on the floor (fig. 3).
Install the vessel in the return line, as close as possible to the boiler, on the intake side of the
pump. Install the vessel so that the water it contains cannot circulate.
1. Apply PTFE tape (D) (do not use hemp!) to the connection of the expansion vessel (fig. 4).
2. Connect the expansion vessel to the installation (Flexconsole, T-piece or expansion pipe).
3. If possible, it is advisable to place the optional connection group in the expansion line for
easy maintenance.
Commissioning
If the factory-set pre-charge does not match the calculated pre-charge for the installation, the
pre-charge must be adjusted. The water side of the vessel should be empty.
Remove the valve cap (F) and adjust the pre-charge. Then replace the valve cap (F).
In the commissioning sequence:
Open the bleed points. (fig. 5)
1.
2. Fill the installation slowly until the fill pressure in the expansion vessel is 0.2 bar higher than
the pre-charge. Bleed the system during filling. (fig. 6)
Bleed the pipe to the expansion vessel. (fig. 7)
3.
Close the bleed points. (fig. 8)
4.
5. Heat the system as high as possible for half a day and bleed regularly.
6. When the water temperature has fallen to approx. 50 °C, top up the installation to 0.3 bar
above the pre-charge of the expansion vessel. Ensure that the filling hose is bled.

1.3. Maintenance and service

The expansion vessel and the pre-pressure must be checked yearly. Any deviations found
must be rectified.
Expansion vessels are pressure equipment, and conform to Pressure Equipment Directive
2014/68/EU. A declaration of conformity is available from Flamco on request.
