9.2D Temperature Switch
The temperature switch comes attached to its own conduit box.
The switch should be installed in an unobstructed portion of the
ductwork between the RotoClone inlet and the Exhaust hood, where
the thermal path is not hindered. It must be installed in the top of the
ductwork so that the temperature switch/probe is hanging vertically.
The switch/probe is installed in the duct by screwing the switch/probe
through the duct and into the bushing in the conduit box until tight.
This secures both the switch/probe and the conduit box to the duct.
9.2E Operation
Refer to the specific Range Hood wiring diagram in the IOM packet,
for sequence of operation.
9.2F Maintenance & Troubleshooting
Refer to Sections 4 and 5 of this IOM for maintenance and cause
of entrainment problems.
RotoClone won’t start or stay running
Water pressure or flow insufficient to actuate flow switch(es).
-Supply water pressure less than 40 psi
-Nozzles plugged
-Strainer plugged
-Water usage elsewhere causes momentary
interruption in flow to RotoClone
-Solenoid valve malfunctioning
Flow switch wired incorrectly
-See Note under Flow Switches
Motor amperage exceeds nameplate full load amps
-Impeller turning backward
-Airflow or static pressure change in ductwork
-Drains plugged
-Motor and RotoClone sheaves reversed
-Motor wired for wrong voltage

9.2C Water Connection
The “shipped loose” piping assembly is attached to the RotoClone at the two unions on the end of the loose piping and connecting pieces
on the RotoClone. Connect the water supply line to the strainer on the other end of the RotoClone piping assembly. It is recommended that
a manual shut off valve (supplied by others) be installed in the supply line to facilitate maintenance on the flow switches and solenoid valves.
The water connection should be capable of supplying the volume listed below at a pressure of 40 psi.
9.3 Auxiliary Impeller Flushing
An auxiliary flushing nozzle is supplied with a manual valve or
automatic solenoid valve to provide extra cleaning for the impeller
while it coasts down to a stop after the motor is de-energized.
9.3A The manual or solenoid valve should be piped up to the water
line that supplies the RotoClone, after the strainer. The connection
size is a ½" FPT on the valve.
9.3B The automatic solenoid valve option includes a timer/relay
in a separate (shipped loose) box. Refer to the wiring diagram
supplied with the unit for connection directions. The timer/relay
is interlocked with the motor starter to open the solenoid when
the “STOP” button is pushed. After the timer runs its preset time,
the solenoid closes, shutting off water to the RotoClone.
Note: The valve should not remain open while the RotoClone
is running. The extra water may cause water entrainment in
the exhaust airstream.
