NOTES:

1) The BELL and SPIGOT must be cleaned andlubricated, if required, prior to assembling each unit.

2) The SINGLE OFFSET GASKET must be placed as per

manufacturer’s recommendations around the spigot

end of the pipe. The gasket must be placed tight to the

spigot shoulder. (See pages P11 and P12)

3) Each unit must be placed squarely on top of the otherto prevent the gasket from unseating itself and

damaging the unit.

NOTE: From time to time we may have to revert back to our old gasket system to meet supply anddemand conditions (see page P13).
