1. Insert the sensor into Inner casing. Make sure that
the sensor cable gland has been taken off. Match the
bayonet closing with sensor flange so that the latch is
slightly to the left of the top and the sensor cable
passage is straight down.
2. When sensor flange is flush with the bottom of Inner
casing, rotate Inner casing 60 degrees clockwise to lock
it to the flange.
3. Push down locking latch to secure the connection.
1. Fit Outer casing over Inner casing. To match the
casings, check that the rail on the Inner casing matches
the groove on Outer casing. The latch of Inner casing
should be slightly to the right from the top and the
handle of Outer casing should point up.
2. Turn the hand-wheel clockwise until it stops to draw
the Inner casing with sensor into Outer casing.
1. The sensor should now be inside Retractor and
about 140 mm (5.5") of the screw thread should stick
out of the middle of the wheel.
2. Unlock the latch on Outer casing.
3. Take a firm hold of the hand-wheel and handle and
lift Retractor (with sensor) over the isolation valve
flange. Keep handle up.
1. Rotate Outer casing 60° clockwise to lock the
bayonet.
