1.0 Description
The Type W RotoClone is a complete dust control unit. It combines
exhauster and dust collector in a single compact unit, and continuously
discharges the collected material in a slurry form.
The Type W RotoClone has been designed to perform its various
functions automatically and requires very little maintenance. Like
any other mechanical equipment, however, it should have regular
attention and be operated according to instructions to ensure long
life and trouble-free service.

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.

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.

2.3 Duct Connections (Arrangement A)
Inlet and discharge ducts must be supported from floor, wall, or ceiling, and not by the RotoClone. The joint between the RotoClone inlet and
exhaust main must be water-tight. Inlet duct should slope downward with bottom of duct no lower than bottom of RotoClone inlet. There should
be at least four (4) duct diameters of straight run leading to the inlet of the RotoClone or performance may be impaired. Discharge duct should
extend above roof line and should discharge the air vertically upward. It should be of same diameter as the RotoClone inlet and seams must
be soldered or welded water-tight. A gasket (not furnished) should be placed between the outlet connection and the discharge duct to make
joint water-tight. A weather hood is not required. Expansion chamber should be vented per Figure 3, where recirculation of discharge air
is not permitted.

Figure 3 — Expansion Chamber Venting Diagram
(Arrangement D)
Instructions same as Arrangement A except on Arrangement D, the
joint between Precleaner inlet and exhaust main must be water-tight.
2.4 Water Connections (Arrangement A)
RotoClone piping may be shipped loose to prevent damage during
shipping. Connect the two lines from the “cross” to the two
connections on the RotoClone inlet. The third outlet from the cross
connects to the pressure gauge supplied and the front leg should be
connected to the water supply line. Supply line should be 3/4” size for
RotoClones through size 14; 1” size for size 16 RotoClones and larger
and designed for supply line water pressures. Connect the water
supply line to strainer located near RotoClone inlet, using pipe at
least as large as the strainer connection. The Solenoid Valve, should
be installed between the strainer and cross, and should be wired
in parallel with the RotoClone motor per the wiring diagram supplied
with the unit. Solenoid valves should always be installed with the coil
in the top, vertical position. Finished piping should be per Figure 1.
It is recommended that a manual shut-off valve be installed in
the supply line, to be able to do maintenance on the solenoid valve.
The water connection must be capable of supplying the volume listed
in Section 6, Table 1 to the spray nozzles at 40 to 60 psi pressure.
(Arrangement D)
Instructions same as Arrangement A, strainer located near Precleaner
inlet. Refer to Figure 2 for Pressure Gage Installation.
A by-pass connection with manual valve per Figure 4 (both
Arrangement A and D) may be included to safeguard operation
of RotoClone in case of solenoid valve failure or for strainer
maintenance.
2.5 Average Water Requirements
See Section 6.0, Table 1 for average water required.
2.6 Wiring & Controls
Refer to the wiring diagram supplied with the unit for
recommended connections.
