5. Connections in Conduit Box
Now that the wires have been routed through the port in the AQUAVAR controller.
• Conduit and wires should be trial routed and cut to length at this time. After wire is routed
through, insert connector through hole in conduit box and fasten with locknut.
6. Mount the thermistor into the conduit box so the metal side of the sensor will contact the
motor shell when mounted.
7. The 4 remaining wires routed
from the terminal block U, V, W,
and ground screw, should now
be connected to the motor leads
using the motor nameplate. See
Diagram 7 for reference.
• Always check with motor
manufacturer for actual motor
wiring!
8. Pressure Transducer Installation and Wiring
It is recommended that the transducer be mounted in the discharge piping. The location
should be in a non-turbulent, straight piece of pipe. See layout on page 5.
9. Transducer should be placed downstream of system check valve in a non-turbulent section of
piping. Ensure cable plug is secure to transducer connector.
• The transducer is supplied with NPT threads for direct mounting in the discharge piping.
• The transducer should not be stored in freezing temperatures.
