Installation
CAUTION
Please observe the following to ensure that the
JSAV is not damaged during installation:
– Sealing material, cuttings and other impurities
must not be allowed to get into the housing.
– We recommend installing a filter upstream of the
JSAV in order to protect it against impurities in
the pipe.
– The installation location must be dry. Do not
store or install the JSAV in the open air.
– Install the JSAV in the pipe free of mechanical
stress.
– Do not clamp the unit in a vice or use it as a
lever. Risk of external leakage.
– Max. inlet pressure p
u max.
5 bar (72.5 psig).
– Installation in the vertical or horizontal position,
never upside down.
The housing must not be in contact with ma-
sonry. Minimum clearance 20 mm (0.78"). Ensure
that there is sufficient space for installation and
adjustment.
Remove the adhesive foil from the inlet and outlet
on the JSAV.
Insert seal between pipe and unit.
