Elements must always be installed according to
local building regulations and wiring rules as
well as the guidelines in this installation manual
• Any other installation may hamper element
functionality or constitute a safety risk, and
will void the warranty.
• Make sure that elements, cold leads, connec-
tion boxes, and other electrical components do
not come into contact with chemicals or flam-
mable materials during or after installation.
Elements must always be connected by an au-
thorised electrician using a fixed connection.
• De-energize all power circuits before installa-
tion and service.
• The connection to the power source must not
be directly accessible to the end user.
• Each heating cable screen must be earthed in
accordance with local electricity regulations and
connected to a residual current device (RCD).
• Recommended RCD trip rating is 30 mA, but
may be up to 300 mA where capacitive leak-
age may lead to nuisance tripping.
• Heating elements must be connected via a
switch providing all pole disconnection.
• The element must be equipped with a cor-
rectly sized fuse or circuit breaker, e.g. 10/13 A
for a 1.5 mm
2
cold lead and 16/20 A for a
2.5 mm
2
cold lead.
