AAF International Type W RotoClone - Manual (Page 3)

2.0 Installation
The following instructions should be read carefully before installing
the RotoClone.
2.1 Foundations
Foundations must be true, level, and rigid enough to prevent vibration
and support the weight of the RotoClone. (See Section 6, Table 2 for
net weights of RotoClone.)
2.2 RotoClone Erection (Arrangement A)
Refer to Installation Diagram - Figure 1. Assembly of the RotoClone
should proceed in the following manner sealing all joints using
gaskets and bolts included with shipment. Some RotoClones,
size 16 and smaller, have inlet, outlet, and expansion chamber
welded to housing in lieu of flanged and bolted connections.
1. 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.
2. Bolt RotoClone on foundation. If vibration isolators are used,
a sub-base must be used to support the exhauster with the
isolators located at each corner of the sub-base. Connecting
ductwork requires flexible connections when vibration isolators
are used.
3. Bolt RotoClone inlet connection to RotoClone inlet.
(Note: Eliminate elbows and other inlet obstructions if at all
possible. Sharp elbows at the fan inlet or other disturbances
will seriously reduce the air volume and can affect the RotoClone’s
dust collection efficiency. A minimum of 4-5 inlet diameters of
straight duct prior to the RotoClone is recommended to evenly
distribute airflow.)
4. Bolt expansion chamber to water outlet.
Discharge stack supplied by others.
Extend vertically above roof line.
Joints must be made water-tight.
Supply gasket at RotoClone connection.
