Sensor Installation
Warning:
All electrical work should be
performed by a qualified electrician in
accordance with the latest edition of the
National Electrical Code, local codes and
regulations.
CAUTION:
Power must not be applied to any of the
wires during the rough-in wiring stage.
CAUTION:
All field wiring must pass through a suitable
listed conduit fitting, to ensure proper strain relief.
CAUTION:
All field installed wiring should meet or
exceed requirements for class 2 wiring per article 725
of the National Electrical Code rated at 30VAC 250VA.
Ensure that enough wiring is in the control box to
reach the terminal strip.
NOTE:
All field wiring shall have insulation stripped
exposing 6.0mm of conductor before placement into
control box terminal strip.
If the terminal box position needs to be changed, ensure
that the electrical supply is turned off and close the
isolation valves before removing the Allen screws.
To change control box position:
•
Remove the four (4) Allen screws (4 or 5mm
wrench) while supporting the stator (motor).
•
Carefully separate the stator from the pump
chamber and rotate it to the correct terminal box
orientation.
•
Replace the Allen screws and tighten diagonally
and evenly (7 ft. –lb. torque).
•
Check that the motor shaft turns freely. Remove
the large screw in the middle of the nameplate,
insert a small flat blade screwdriver into the end of
the shaft, and turn gently.
•
If the shaft does not turn easily, repeat the disas-
sembly/reassembly process.
