Pressure safety:
The installation must be protected against any risk of pressure surges. Special care
must be taken to protect against the risks linked to expansion of the energy transfer
fluid and to the total hydrostatic pressure.
Filtration:
An efficient filtration system (recommended efficiency of 0.5 mm) should be fitted on
the supply water and return water lines.
Flushing:
The system must be flushed completely and filled with treated water to prevent the build-up
of scale or sludge in the circuit. When flushing the system, open the valve on the unit to
prevent any sludge or scale entering the coil:
Thermo valves: Remove the servomotor to fit the cap, which will cause pressure
l
to be applied to the shaft, thereby opening the passage, or request that the valve
is opened by the control.
3-point modulating valves: If the power has not yet been switched on, the valve
l
will be open by default. If the control has already been powered up, remove the
servomotor to release the rod and open the passage.
Filling:
Drain the coils during commissioning.
