- THE PLANT SHOULD ONLY BE LOADED BY NATURAL FALL FROM THE EXPANSION VESSEL AND
ABSOLUTELY NEVER DIRECTLY FROM THE WATER SYSTEM (Water in the network has a higher
pressure than our generator can take).
NB: THE MAXIMUM PRESSURE OF WORKING OF THE GENERATOR SHOULD NEVER EXCEED 1.5 BAR
The expansion vessel must consist of a covered container located above the highest point reached
by the water in the system.
- Safety tubes, loading and venting must be protected from freezing in case this may occur
- The safety pipe needs to connect the highest part of the generator with the atmosphere and
have no counterslopes, except in cases when it is intended to come out in the
top of the tank.
- The inlet pipe needs to pool the lower part of the generator with the lower part of the expansion
and does not have to have counterslopes that prevent the movement by gravity into the circuit
(security and inlet pipes, generator, expansion vessel).
The vent tube communicating with the outside must have at least the same size of the
safety pipe. As vent pipe can also be used the overflow pipe - which has at minimum the size of
the security tube.
Where applicable it can be useful to install the heater on a lower level compared to the radiators
to help finishing the thermal energy.
It may be convenient to use a water softening filter to reduce the formation of limestone in case
of very hard water.
