Note

•  Be sure to follow your local regulations to perform system configuration of the DHW connections.

•  DHW connections are not included in the hydrobox package.  All required parts are to be sourced 

locally.

•  To enable draining of the hydrobox an isolating valve should be positioned on both the inlet and 

outlet pipework.

•  Be sure to install a strainer on the inlet pipe work to the hydrobox.

•  Suitable drain pipework should be attached to all relief valves in accordance with your country's 

regulations.

•  A backflow prevention device must be installed on water supply pipework (IEC 61770).

•  When using components made from different metals or connecting pipes made of different metals 

insulate the joints to prevent a corrosive reaction taking place which will damage the pipework.
