TO INSTALL REPLACEMENT ACTUATOR
NOTE:
Installation of a new actuator does not require
draining the system provided the valve body and
valve cartridge assembly remain in the pipeline.
1.
Check replacement part number and voltage ratings
for match with old device.
2.
Disconnect power supply before servicing to avoid
electrical shock or equipment damage.
3.
Disconnect leadwires to actuator, or depress tab on
Molex™ connector and remove. Where appropriate,
label wires for rewiring.
4.
The actuator head is automatically latched to the
valve. To remove, press up on the latch mechanism
located directly below the white manual open lever
with thumb (See Fig. 5). Simultaneously press the
actuator down towards the body with moderate hand
force and turn the actuator counter-clockwise by
1/8 turn (45 degrees). Lift actuator off the valve
body.
NOTE:
The actuator can also be installed at right
angles to the valve body but in this position
the latch mechanism will not engage.
5.
Install the new actuator by reversing the process in (4).
6.
Reconnect leadwires or Molex™ connector.
7.
Restore power, and check out operation.

MANUAL OPENER
The manual opener can be manipulated only when in the
up position. The “A” port can be opened by firmly pushing
the white manual lever down to midway and in. In this
position both the “A” and “B” ports are open, and with
auxiliary switch models the switch is closed. This "manual
open" position may be used for filling, venting, or draining
the system, or for opening the valve in case of power
failure. The valve can be restored manually to the closed
position by depressing the white manual lever lightly and
then pulling the lever out. The valve and actuator will
return to the automatic position when power is restored.
NOTE:
If the valve is powered open, it can not be
manually closed unless actuator is removed.
