NOTICE
▪
It is recommended to install shut-off valves to space heating in and space heating
out connections. Shut-off valves are field supplied. They allow service to the unit
without draining the whole system.
▪
Foresee a drain/fill point to drain or fill the space heating circuit
NOTICE
Do NOT install valves to shut down the entire emitter system (radiators, floor heating
loops, fan coil units, ...) instantly if this can result in an immediate short circuit of the
water flow between the outlet and the inlet of the unit (for example via a bypass
valve). This may trigger an error.
