Systems with New Style Valve Bodies (Series 6)
IMPORTANT
On a new style valve body or a valve body that was
converted to accept the new powerhead, it is not
necessary to drain the system if the valve body
remains in the pipeline.
쐃 Disconnect the power supply before connecting the
wiring to prevent electrical shock or equipment
damage.
쐇 Disconnect the leadwires to the powerhead at the
terminal block or conduit connection. Remove the
conduit or cable connector, if fitted. Label each wire for
rewiring.
쐋 Remove the old powerhead (see Fig. 13):
a. Place the manual opening lever (normally closed
models only) on the old powerhead in the MAN.
OPEN position (Fig. 13A).
b. Remove the screw securing the cover to the
powerhead (Fig. 13B).
c. Lift off the cover from the powerhead.
d. Remove the two screws securing the powerhead
to the valve body (Fig. 12).
e. Lift the powerhead off the valve body.
쐏 Install the new power head (see Fig. 12):
a. Place the manual opening lever (normally closed
models only) on the new powerhead in the MAN.
OPEN position.
b. Fit the powerhead onto the valve body, ensuring
that the shaft seats correctly. The powerhead
should be aligned with the manual opening lever
or slot for lever at the port A end of the valve body.
c. Secure the powerhead to the valve body with the
two screws provided.
d. If fitted, reconnect the conduit or cable. Reconnect
the leadwires to the powerhead.
e. Replace the powerhead cover.
쐄 Turn on the power.
Wiring
Disconnect the power supply before connecting wiring to
prevent electrical shock or equipment damage.
All wiring must comply with local codes and ordinances.
Connections to the individual valves are shown in Fig. 14
and 15. See Fig. 16 through 22 for typical hookups.
If replacing a Taco, Dole, Flair or White Rodgers 3-wire valve
with a 2-wire V8043E or F, see Fig. 23 through 35. Check
that the pressure rating of the new valve is appropriate for
the application.
