SYSTEM CONNECTIONS
Make the connections to the corresponding fittings shown in the diagram above. Make sure the pipes are not placed under tension or
undersized.
If installation of the product involves interaction with another, pre-existing system complete with heating equipment (gas boiler,
methane boiler, diesel boiler, etc.), call in qualified personnel, who subsequently will be responsible for conformity of the system in
compliance with the applicable law in force.
IT IS STRONGLY RECOMMENDED TO WASH THE ENTIRE SYSTEM BEFORE CONNECTING IT IN ORDER TO GET RID OF
RESIDUES AND DEPOSITS.
Upstream from the product, always install gate valves so as to disconnect it from the plumbing system should it be
necessary to move it, or when it requires routine and/or special maintenance. Connect the product using hoses in
order not to constrain it excessively to the system.
The pressure discharge valve (B) is always connected to a water drain pipe. The pipe must be adequate to support the
water's high temperature and pressure.
SYSTEM WASHING
It is mandatory for the connections to be easily disconnectable via unions with swivel fittings. Fit suitable gate valves on the heating
system pipes.
To protect the heating system from harmful corrosion, fouling or deposits, it is of the utmost importance, before installing the product, to
wash the system in compliance with UNI-CTI 8065, using appropriate products such as, for example, Sentinel X300 (new systems), X400
and X800 (old systems) or Fernox Cleaner F3.
Complete instructions are provided with the products but, for further clarifications, please directly contact the manufacturer SENTINEL
PERFORMANCE SOLUTIONS LTD or Fernox COOKSON ELECTRONICS.
After flushing the system, to protect it against corrosion and deposits, we recommend the use of inhibitors such as Sentinel X100 or Fernox
Protector F1.
It is important to check the concentration of the inhibitor after each change to the system and during maintenance as prescribed by
manufacturers (specific tests are available at dealers).
The discharge of the safety valve must be connected to a collecting funnel for conveying the possible dredges in case of intervention.
Attention: failure to clean the heating system and the addition of a suitable inhibitor will void the warranty of the
equipment and other accessories such as for example pumps and valves.
