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
u
4 bar (58 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.
JSAV..R: seal pipe with approved sealing material.
Remove screw caps from the inlet and outlet on
the JSAV.
▷
Note direction of flow.
