5 Installation
All pipes connecting to the tank should have removable connections (fitting/flange). Pipe thread seals with teflon are
to be avoided.
All tank connecting pipes are to be planned, constructed and tested according to the technical rules in force, as well as to the
corresponding norms and regulations in accordance with their application and supply medium.
Appropriate filters should be used to prevent dirt or particles from entering the tanks. Moreover, the tank should be ensured
against pressure fluctuations and excess pressure through the installation of tested pressure reducing valves and safety
valves.
Sensors and thermostats necessary for temperature control must be securely and permanently positioned on the tank
(immersion sleeve and sensor rail).
The tank's venting and draining facilities must have the appropriate dimensions and be correctly installed.
The installation company is responsible for the correct execution of work and for the safe and careful insulation of the pipes.
•
When connecting to a solar plant, a temperature limiter is required and must be installed on site at the hot water outlet
in order to prevent scalding.
