Water supply connections
Units are supplied with a 1” (FPT) quick fill valve and ¼” (FPT) solenoid
valve for automatic water makeup. Connect supply piping to both.
9.2.5
Drain Connection
A 2” (FPT) drain valve is supplied at the bottom of the hopper. Drain piping,
should be attached here and to the 1” (FPT) overflow coupling on the side of the
sludge chute.
9.2.6
Ductwork Installation
In order to prevent surging within the RotoClone, four to five duct diameters
length of straight run prior to the inlet will provide uniform distribution at the inlet.
If an elbow is required due to space constraints, turning vanes must be used in the
elbow to evenly distribute the air and prevent surging.
Inlet and exhaust ductwork must be supported from the floor, wall or
ceiling; not from the RotoClone or fan exhauster. Depending on the application
and local conditions, the discharge from the exhauster may be either returned to
the workroom or discharged to the atmosphere. It may be desirable to have both
outside and inside discharges fitted with a selective damper. This will save heat in
the winter with recirculation and aid ventilation by discharging outside during the
summer months. When a discharge duct is required, it should extend above
adjacent roof lines and should discharge vertically upward. As long as there is a
drain in the fan housing, a drain cap or weather hood should not be used. Cross-
section of the discharge duct should not be less than the exhauster outlet area.

Water Level Control Options
Supply water makeup for the RotoClone is required because of water losses
due to evaporation and sludge removal. Makeup water will maintain the proper
water level in the unit by entering the RotoClone through the RotoClone/Control
box connection.
The Model A control is the only water level control available on the
RotoClone LVN.
10.1
Model “A” Control
This control box is used when there can be no water overflow from the
RotoClone. Makeup water will be added to the system only when the requirement
exists. This control also prevents the RotoClone from operating when there is
insufficient water level.
