General pipe connections
Pipe installation must be carried out in accordance with current norms and directives.
Maximum of 10 bar safety valve must be installed in the supply pipe before any shut-off valve. The safety
valve must be dimensioned so that its blowdown force with steam is equal to the boiler power. The size of
the blowdown pipe cannot be reduced from its nominal size and must be positioned so that the steam
discharge does not cause any personnel injuries or property damage.
When installing pipes, special attention must be given to the installation of safety valves, expansion
installations and possibility for air discharge in the electric boiler discharge pipe. The direction of flow must
be marked on the supply and return pipes.
Note! Any high points in the climate system, must be equipped with air vents.
Note! The pipe systems need to be flushed out before the boiler is connected so that any debris cannot
damage component parts.
Note! The main switch must not be moved to "I" (on) until the system has been filled with water and water
circulation is ensured. Otherwise the temperature limiter, thermostat and the immersion heater etc. can be
damaged.
