6. Wiring the circulator:
Disconnect the AC power supply. Remove the terminal box cover. Attach a wiring connector into the knockout hole.
Use a flexible conduit only. Connect Line/Hot power to the black lead, neutral to the white lead. See wiring diagram to the right. Replace the
terminal box cover.
Note:
If pigtail leads provided are not used, be sure to trim field wire to a strip length of .25” (+/- .025”) to prevent exposed wire causing a short at the
terminal plug. Connect line and neutral to green terminal plug as shown in the Wiring Diagram. Depress the spring tab with a small screwdriver to
insert wire into the plug. Release tabs to complete connection. The 0018e is a double insulated circulator. No grounding wire is necessary.
7. Start the circulator:
When purging the system, it is recommended to run the circulator at manual full speed operation long enough
to remove remaining air from the bearing chamber. To do this, turn the dial clockwise to the ZONE CIRC - MAX position. This is especially
important when installing the circulator in the off-season.
Full Speed Operation:
To run the pump at full speed during the fast fill, start-up and purge process, rotate dial clockwise
to MAX speed setting. To return to the normal operating mode, turn dial to desired fixed speed, constant pressure, or
proportional pressure setting.
CAUTION:
Never run the circulator dry or permanent damage may result.
ATTENTION:
Ne laissez jamais le circulateur tourner à sec, des dommages permanents peuvent en résulter.
