A 1 Connection set, DN 32/32 DVGW
A 1 1 Intended use
The corrugated hoses with G 1¼" internal threads
may only be used to connect water softeners.
Corrugated hoses ensure a strain-free connection
to the water softener. They eliminate the time-con-
suming process of adapting and fitting metal pipes
for this purpose.
A 1 2 Installation conditions
Corrugated hoses are only suitable for drinking
water installations. The chloride content of the
water must not exceed 250 mg/l.
Corrugated hoses must not be shortened.
Never strain or twist the corrugated hoses during
installation. Do not try to fold or squeeze them.
The minimum bending radius of the hoses is
50 mm.
The corrugated hoses are not to come into con-
tact with plaster, cement, salt or other corrosive
materials.
Do not install the corrugated hoses in water. The
outer surface must remain dry.
Both ends of the hose must have access to air for
the installation.
If necessary, the corrugated hoses can be insulated
against splash water. Make sure the hoses are dry
when attaching the insulation covering.
The space between the corrugated hoses and the
insulation covering must be free of any air pockets.
Non-compliance with the installation conditions and
the operator responsibilities voids the warranty.
