REPLACEMENT OF THE BALL RELEASE GROUP SEAL
In case there is a loss of material from the ball release group
(P39), it is necessary to replace the gasket (X1) as shown.
• For correct reassembly, see the drawing of the pump unit,
and follow disassembly operations in reverse order.
• Once the unit has been correctly positioned, tighten the
lock nut (P37) hard against the front template.
To tighten, use a 45 mm spanner.
• Close the inspection cover (P2) again.
• Fit the suction pipe (P38).
Put PTFE tape or liquid PTFE over the threaded part before
screwing it onto the foot valve.
