AAF International Type W RotoClone - Manual (Page 4)

RotoClone Erection (Arrangement D)
Refer to Arrangement D Erection Diagram - Figure 2. Assembly
should proceed in the following manner, using gaskets and bolts
included with shipment for each joint. Some RotoClones, sizes 16 and
smaller, may have inlet, outlet, and expansion chamber welded to
housing in lieu of flanged and bolted connections.
1. Place hopper section on foundation and anchor.
2. Bolt precleaner section to hopper top. (Note: On RotoClones
sizes 8 through 20, the hopper and precleaner sections
are normally shipped assembled.)
3. Bolt RotoClone outlet connection to RotoClone outlet. Be sure
that the bottom of the outlet piece is even with the bottom of the
RotoClone outlet and that no gasket material is protruding inside
as this will cause water carryover.
4. Bolt RotoClone to precleaner top. (Note: On RotoClones sizes
8 and 10, RotoClone is shipped assembled to precleaner
and hopper.)
5. Bolt precleaner outlet connection to precleaner section.
(Note: On RotoClones sizes 8 through 16, the precleaner
outlet connection and precleaner are shipped assembled.)
6. Bolt RotoClone inlet connection to RotoClone inlet and
precleaner outlet connection.
7. Connect hose from water drain in RotoClone outlet connection
to nipple provided in hopper using fittings provided.
