The
connection to the ball valve is made using a flexible filling loop.
This may be left connected during operation to provide automatic
re-filling via the ball valve. An overflow will be required.
Alternatively, the filling loop may be disconnected during operation, with
the unit manually re-filled. In this type of installation, no
overflow is required.
The unit is suitable
to supply a heating load of 3kW, less hot water usage.
No special
qualifications are required to install this unit, however installers must
be competent in the basics of plumbing and wiring.
