Fafnir TORRIX Flex Guia De Instalacion página 9

Please note that the flexible and therefore fragile nature of the TORRIX Flex sen-
sor makes it more prone to mechanical shock. The sensor must not be
unpacked until it has been brought to its place of installation.
The corrugated hose must not be bent more than it already is in the packaging
and must not be pulled apart in axial direction.
Installation must be carried out by at least two persons, one of whom unrolls the
corrugated hose while the other feeds the corrugated hose into the tank.
The sensor is supplied in a special transport box.
The float and the weight are ready assembled. Before installation, prepare a spanner (AF 55)
and some sealing material for the screw-in unit, a hexagon key (5 mm), a spanner (AF 30)
for the stuffing box, and a measuring instrument.
(1) Remove the sensor from the packaging
(2) If there is deformation or kinking at the transition between probe tube and corru-
gated hose, this must be straightened out with extreme care
(3) Loosen the hexagon-socket screw and stuffing box, slide the screw-in unit towards
the sensor head and secure, then seal in the thread of the screw-in unit
(4) Slide the float onto the weight at the lower end of the probe
(5) Feed the lower end of the probe (magnetic base) into the tank
(6) Unroll the corrugated hose, taking care to avoid chafing on the tank coupling, until
the top end of the corrugated hose reaches the tank coupling
(7) Then lower the sensor slowly until you feel the magnetic force of the magnetic base
take hold on the tank bottom (steel tanks only)
(8) In this position, measure the clearance from the lower edge of the sensor head to
the tank lid (installation dimension) and note it down
(9) Lower the sensor head slightly, slide the screw-in unit towards the tank coupling and
tighten
(10) Raise the sensor head until the exact installation dimension that you measured
before is achieved again. Attention: do not raise it any higher, otherwise the sensor
will become detached from the tank bottom
(11) Tighten the stuffing box and secure using the hexagon-socket screw
