2 Installation
This system MUST be fitted by a qualified and
approved installation engineer, proceeding as
shown in the illustrations on pages 106 to 109. The
relevant safety guidelines should be followed at all
times.
There is a danger of fatal injury from tou-
ching live components. Always shut off
the power supply to the system (and
ensure it cannot be reconnected) BEFORE
carrying out installation or maintenance
work.
Note that we will accept no liability whatsoever for
injury or damage resulting from failure to observe
these instructions. This condition applies especially
to incorrect wiring and/or defective mechanical
installation.
Two-point or constant regulation (page 107)
Two-point regulation (factory-adjustment)
is required if the power rating of the hea-
ting system is considerably more than the
calculated heat requirement (e.g. in order
to achieve a greater hotwater capacity).
Constant regulation is recommended if
the heat rating corresponds to the calcu-
lated heating requirement.
