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 nec-
essary to drain the system if the valve body remains
in the pipeline.
1. Disconnect the power supply before connecting the wir-
ing to prevent electrical shock or equipment damage.
2. Disconnect the leadwires to the powerhead at the termi-
nal block or conduit connection. Remove the conduit or
cable connector, if fitted. Label each wire for rewiring.
3. 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 power-
head (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.
4. 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.
