ity of the fixing elements used is insuffi-
cient!
If the fixing elements do not have sufficient
load-bearing capacity, the product can
come loose and fall down.
•
When fitting the product, ensure that the
fixing elements have a sufficient load-
bearing capacity.
∙
Determine the assembly location.
∙
Drill the holes to receive the fastenings (see chapter 4.1).

Caution!
Risk of damage caused by contaminated
lines!
Foreign bodies such as welding remnants,
sealing residue or dirt in the supply lines
can cause damage to the product.
•
Flush the supply lines thoroughly before
installation.
b
Caution!
Risk of damage caused by heat transfer
when soldering.
Heat that is transferred during soldering
can cause damage (expanded) polypropyl-
ene 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 corro-
sion inhibitor to the circuit water.
