Installation
VPA 300/200 can be equipped with the following ele-
ments, connection dimension G50. When installing the
water heater, ensure that there is enough room in front
of the connection area to remove the element, see fol-
lowing table.
Fit the enclosed cover discs before pipe installation. The
cover discs, with self-adhesive backs, must be installed
on the relevant connection, by pushing them over the
connections.
All connections (including connections or holes left by
the lifting eyes that are not used) must be insulated to
minimise energy losses.
