Installation on the tank
•
Do not forget the gasket when
positioning the BM 702 on the tank
nozzle flange. Align BM 702 and gasket,
slightly tighten nuts on stud bolts (by
hand).
•
Press
shielding strip C*
in the gap
between tank and BM 702 flanges and
secure with
strap retainer S*
(both
items included with supply).
•
Strap retainer S*
must fit closely and
overlap both flanges.
* only required for European radio approvals
•
Tighten down stud bolt nuts firmly. The
tightening torque is dependent upon
the strength properties of the stud
bolts and the pressure rating of the
tank
C* = shielding strip B = BM 702 flange
