Mounting the heater
The Hydro 55 is ideally installed in the engine room
away from any water that may interfere with the
system whilst still being low enough to allow automatic
bleeding of the heater and circulation pump. This is
particularly important as the circulation pump is not
self-priming.

any installed position and allow for the rating plate to
