Risk of damage caused by heat
transfer when soldering.
Heat that is transferred during sol-
dering can cause damage
(expanded) polypropylene around
electrical modul and to the seals in
the service valves.
►
Protect (expanded) polypropylene
of electrical modul
►
Do not solder the connection
pieces if the connection pieces
are screwed to the service valves.
b
Caution!
Risk of damage due to corrosion.
If plastic pipes that pass oxygen are
used in the heating installation, this
may corrode or sludge up the
appliance’s heating circuit or the
appliance itself.
►
If you use plastic pipes that pass
oxygen in the heating installation,
add a corrosion inhibitor to the cir-

separation of at least 3 mm between each contact).
Additional protection may be required during the installation
to ensure overvoltage category II.
Switching devices from the mains supply must allow
complete failure of the supply according to the requirements
of the overvoltage category III.
