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. On the JSAV..R, only secure the valve by
holding the octagon at the inlet or outlet with a
suitable spanner. Risk of external leakage.
– Max. inlet pressure p
e max.
4 bar (58 psig).
– Installation in the vertical or horizontal position,
never upside down.

The housing must not be in contact with masonry.
Minimum clearance 20 mm (0.78"). Ensure that
there is sufficient space for installation and adjust-
ment.

JSAV..R: seal pipe with approved sealing material.
JSAV..F: insert seal between pipe and unit.
Remove screw caps or adhesive foil from the inlet
and outlet on the JSAV.

We recommend installing a manual valve AKT 25
in the pipe leading to the safety relief valve
VSBV 25, so that the annual function check of
the safety shut-off valve JSAV can be carried out
without having to remove it.
▷
▷
To prevent the VSBV from being unintentionally
shut off, we recommend removing the manual
valve lever after commissioning and attaching
it to the pipe.
