Installation
VPA 450/300 can be equipped with immersion heater,
the connection dimension is G50. During installation,
ensure that there is enough room in front of the connec-
tion area to remove the immersion heater, see table on
page 24.
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.
