Provide suitable safety devices to be installed on the system near the appliance to prevent any possible risk due to overpressure. Suitable
safety devices must be installed in order to prevent exceeding the maximum pressure declared for the device or pipes, in compliance
with current regulations.
Pipes with suitable mechanical characteristics must be used for the installation: use pipes made of metal material adequately fixed to
support structures in order to not mechanically overload the connections and the legs of the device and in way to guarantee a fixed
position of the pipes, also during installation and commissioning.
The device must be installed according to the diagrams given in this manual. It must compulsorily be installed on the return circuit, to
collect the impurities present in the circuit, especially during the system activation phase (closing the by-pass valve at the same time),
before they can reach the boiler.
The drain system must be operated in way that it does not prevent normal operation, avoiding counter pressure and must not endanger
people or things. It must be conveyed into a dedicated pipe or collecting tank. Check compliance with local standards and regulations
regarding the filtration water draining into the sewage system, depending on the substances present in the water and in the sludge
collected and the temperature of the medium.
