READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING.
REMOVAL OF E026 & E029/E030
ACTUATORS FROM VALVE
SEE DRAWING D3400025 on page 15
1) Remove line pressure and isolate valve in piping.
2) Operate actuator so plug is off seat(s).
3) Remove power and signal from actuator. For E026, after
power is removed, cycle Fail-Safe Switch from Up Arrow
to Down Arrow until actuator stem no longer moves.
Adaption/Power (green LED) changes from blinking to off.
Return Fail-Safe Switch to original position. If necessary
use the manual override to operate actuator so plug is off
seat(s) or travel stop in valve.
4) Remove stem connector hex nuts, remove stem connector
U-bolt.
5) While carefully manually holding stem connector clamp
open on the lower portion, use actuator manual override
to raise the stem connector until the stem adapter (item 2)
is disengaged.
5) Loosen yoke locknut (item 4) until it is free of bonnet.
6) Remove space ring (item 3).
7) Remove actuator from valve.
8) Hold jam nut (item 5) on valve stem and turn the stem
adapter to disengage from valve stem. Warning: The
valve stem should never be turned while the plug is in
contact with the seat otherwise the seating surfaces
will be damaged voiding the warranty.
10) Remove stem adapter from valve stem.
11) Remove jam nut from valve stem.
INSTALLATION OF E026 & E029/E030
ACTUATORS ON THE VALVE
SEE DRAWING D3400025 on page 15
THE SILVER SPACER RING THAT COMES WITH THE ACTUATOR MUST BE
ASSEMBLED ON TOP SIDE OF YOKE AS SHOWN ON DRAWING.
1) Push valve stem down until plug is seated. Note stem location.
2) Install hex jam nut (Item 5) on valve stem. Thread jam nut so
that one inch of threads are exposed between jam nut and top
of stem.
3) Hold jam nut on valve stem and turn the stem adapter (item
2) until it bottoms out on the valve stem. Tighten jam nut to
the bottom of the stem adapter to secure valve stem to stem
adapter. Warning: The valve stem should never be turned
while the plug is in contact with the seat otherwise the
seating surfaces will be damaged voiding the warranty.
4) Place actuator, spacer ring and yoke locknut over valve stem
and onto bonnet. Watch orientation of yoke locknut. Actuator
base must rest on bonnet. If necessary, use the manual over-
ride to raise the stem connector.
5) Rotate actuator to desired orientation. For the factory default
actuator position the motor electrical wire end of the actuator
faces the outlet side of a 2-way valve, common port on a 3-way
mixing valve, and lower port on a 3-way diverting valve. Thread
yoke locknut onto bonnet and tighted securely. Use blunt
chisel and hammer for tightening.
6) While holding the bottom of the stem connector open use the
actuator manual override to lower the stem connector over
the stem adapter. Install stem connector U-bolt through the
back half of the stem connector and tighten hex nuts. Evenly
torque the hex nuts per note 9 on drawing D3400025. Warn-
ing: The valve stem should never be turned while the plug
is in contact with the seat otherwise the seating surfaces
will be damaged.
7) Connect power and signal to actuator.
8) Press the Adaption (Auto-Calibration) button on the actuator
and wait until the cycle is complete.
9) Stroke valve several times to check operation.
10) Return line pressure to valve.
