REMOVAL OF E024 & E025
ACTUATORS FROM VALVE
SEE DRAWING D3400024 on page 14
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 E025, 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 oper-
ate actuator so plug is off seat(s) or travel stop in valve.
4) Unlock stem connector clamp, use fingers on the front and
back sides of black lock assembly to evenly raise the lock as-
sembly.
5) Use actuator manual override to raise the stem connector un-
til the stem adapter is disengaged. Warning: Do not loosen
the factory set adjustable height screws on the sides of
the actuator yoke linkage.
6) Loosen yoke locknut (item 3) until it is free of bonnet.
7) Remove spacer ring (item 2).
8) Remove actuator from valve. Warning: Do not loosen the
factory set adjustable height screws on the sides of the
actuator yoke.
9) Hold jam nut (item 4) on valve stem and turn the stem adapt-
er (item 5) 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 dam-
aged voiding the warranty.
10) Remove stem adapter from valve stem.
11) Remove jam nut from valve stem.
INSTALLATION OF E024 & E025
ACTUATORS ON THE VALVE
SEE DRAWING D3400024 on page 14
THE SILVER SPACER RING THAT COMES WITH THE ACTUATOR MUST BE AS-
SEMBLED ON TOP SIDE OF YOKE WITH TURNED DOWN (MACHINED) SIDE
FACING DOWN AS SHOWN ON DRAWING.
1) Push valve stem down until plug is seated. Note stem location.
2) Install hex jam nut (Item 4) 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
5) 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 override to raise the stem connector. Warning: Do
not loosen the factory set adjustable height adjustment
screws on the sides of the actuator yoke linkage.
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 tighten securely.
Use blunt chisel and hammer for tightening.
6) Use actuator manual override to lower the stem connector
over the stem adapter. Lock stem connector clamp, use
fingers on the front and back sides of black lock assembly to
evenly lower the lock assembly.
7 ) Push orange travel indicators together against both sides of
stem connector travel indicator.
8) Connect power and signal to actuator.
9 Press the Adaption (Auto-Calibration) button on the actuator
and wait until the cycle is complete.
10) Stroke valve several times to check operation.
11) Return line pressure to valve.
