VALVE AND ACTUATOR INSTALLATION/REMOVAL
Valve Installation
1. The valve body may be installed in any orientation,
as shown in Figure 23. However, the 3-way actuator's
power connections must be over the closed off port to
ensure proper function and flow direction.
2. Before mounting body, verify there will be enough
clearance for iSeries Smart Actuator to be
installed. It is suggested that the iSeries Smart
Actuator be installed onto valve before valve is
installed. Also, please verify that the nylon washers
are installed to avoid leaking.
3. Make sure the ball valve is in the FULL OPEN
position. Rotate the manual operation button
several times to verify the valve is opening and
closing properly.

iSERIES SMART ACTUATOR REMOVAL
AND INSTALLATION
1. iSeries Smart Actuator may be attached to the valve
body in either direction (see Figure 23). The 3-way
actuator's power connections must be over the closed
off port to ensure proper function and flow direction.
2. Actuator removal: Remove iSeries Smart Actuator
prior to soldering by rotating the actuator
counterclockwise approximately 30 degrees and
lifting upward approximately 3/4" (see Figure 24).
3. To re-assemble actuator to valve body: Position
actuator such that the "D" shaped valve stem
aligns properly with the "D" shaped actuator
drive cavity (NOTE: The "D" shaped stem design
allows for correct insertion every time). Next, slide
valve stem into actuator cavity and rotate until
the actuator slips over the valve's locking posts
(see Figure 24). Once the actuator is flush with
valve body, turn actuator clockwise and lock into
position.
4. To ensure the actuator will function correctly at
start up, there are two checks to conduct.
First, verify the manual operation button (circular
button on top of iSeries Smart Actuator) is in
the upmost position. If the button has been
manipulated/operated at any point during set-up,
the button could be fixed in the manual operation
position. To ensure proper operation, manual twist
the actuator assembly as shown in Figure 24.
Secondly, make sure to re-install the terminal
blocks/plugs into the back of the actuator after re-
installing it. Once power is turned on, there should
be a visual indication of power from the green
LED, located on the back of the actuator. See
