Note
• Be sure to follow your local regulations to per-
form system configuration of the DHW connec-
tions.
• DHW connections are not included in the hy-
drobox 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 coun-
try'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.
