Read all instructions carefully before beginning.
TURNING THE ACTUATOR LEGS CAUSES DAMAGE TO THE AC-
TUATOR AND VOIDS THE WARRANTY.
REMOVAL OF VM1500E ACTUATOR FROM VALVE
1) Remove line pressure and isolate valve in piping.
2) Operate actuator so plug is off seat(s) and tabs of anti-rotation device
(Item 2) can be unbent in Step 5.
3) Loosen jamnut (Item 3) and thread to bottom of threads on valve
stem.
4) Loosen yoke locknut until it is free of bonnet.
5) Unbend tabs of anti-rotation device.
6) Remove anti-rotation device from stem connector so stem connector
may be turned.
7) Hold jamnut on valve stem and turn the stem connector to disengage
from valve stem. The valve stem should never be turned while the
plug is in contact with the seat otherwise the seating surfaces
will be damaged.
8) Remove actuator from valve.
_______________________________________________
INSTALLATION OF VM1500E ACTUATOR ON VALVE.
THE BRASS SPACER THAT COMES WITH THE ACTUATOR MUST BE ASSEMBLED
ON BOTTOM SIDE OF YOKE AS SHOWN ON DRAWING C3400002.
1) Push valve stem down until plug is seated. Note stem location.
2) Install hex jamnut (Item 3) on valve stem. Thread jamnut to bottom of
threads on stem.
3) Place actuator, yoke locknut, and anti-rotation device (Item 2) over
valve stem and onto bonnet. Watch orientation of yoke locknut and
anti-rotation device. Anti-rotation device must be oriented so tabs
can be bent around cross bar in Step 6. Actuator must rest on bonnet.
If necessary use actuator manual override to reposition the stem
connector. The manual override is at the top of the actuator. Turn
override using a 4mm hex wrench. Do not tighten yoke locknut at
this time.
4) Rotate actuator to desired orientation. For the factory default
actuator position face the actuator circuit board and install the
actuator on the valve with the valve upright and its inlet to the left.
Thread yoke locknut onto bonnet and tighten securely. Use a blunt
chisel and hammer for final tightening.
5) Lift valve stem. Hold jamnut on valve stem and turn the stem
connector to engage valve stem. If necessary use actuator manual
override to reposition the stem connector. The valve stem should
never be turned while the plug is in contact with the seat
otherwise the seating surfaces will be damaged. The minimum
required stem engagement is 3/8 inch (9.53 mm). After required stem
engagement is reached thread jamnut up valve stem to contact stem
connector. Tighten jamnut to secure valve stem to stem connector.
6) Install anti-rotation device on cross bar and bend tabs over so stem
connector will not turn.
7) Push red travel indicators on leg of actuator into contact with cross
bar. Connect power to actuator. On circuit board turn dipswitch 9
ON then OFF. Actuator will perform automatic stroke adjustment. In
the stem down direction the plug must reach the seat in the valve
before the brass bar on the shaft inside the motor housing contacts
the bottom of the motor housing. The lever extending through the
hole in the circuit board deflects to depress the upper microswitch on
the circuit board to stop the motor at that end of travel. In the stem up
direction the plug must reach the upper seat or travel stop inside the
valve before the stem connector contacts the bottom of the motor
housing. The lever extending through the hole in the circuit board
deflects to depress the lower microswitch to stop the motor at that
end of travel. If necessary turn off power, loosen jamnut, remove anti-
rotation device from stem connector, and repeat Steps 5 thru 7.
8) Turn off power. Make necessary dipswitch settings and additional
wiring connections. See Set-Up and Wiring sections of these
instructions.
9) Return power to actuator.
10) Return line pressure to valve.
11) Stroke valve several times to check operation.
Read all instructions carefully before beginning.

REMOVAL OF VM5000E ACTUATOR FROM VALVE
1) Remove line pressure and isolate valve in piping.
2) Operate actuator so plug is off seat(s) and anti-rotation device (Item 2)
can be removed in Step 4.
3) Loosen jamnut (Item 3) and thread to bottom of threads on valve stem.
4) Remove anti-rotation device from stem connector so stem connector
may be turned.
5) Loosen yoke locknut until it is free of bonnet.
6) Hold jamnut on valve stem and turn the stem connector to disengage
from valve stem. The valve stem should never be turned while the
plug is in contact with the seat otherwise the seating surfaces

INSTALLATION OF VM5000E ACTUATOR ON VALVE .
THE BRASS SPACER THAT COMES WITH THE ACTUATOR MUST BE ASSEMBLED
ON BOTTOM SIDE OF YOKE AS SHOWN ON DRAWING C3400001.
1) Push valve stem down until plug is seated. Note stem location.
2) Install hex jamnut (Item 3) on valve stem. Thread jamnut to bottom of
threads on stem.
3) Place actuator, yoke locknut, and anti-rotation device (Item 2) over
valve stem and onto bonnet. Watch orientation of yoke locknut and
anti-rotation device. Actuator must rest on bonnet. If necessary use
actuator manual override to reposition the stem connector. The
manual override is at the top of the actuator. There are two rubber caps
on the actuator cover. One cap covers the override; the second cap
covers the clutch. Remove both caps. Depress clutch and turn override
using an 8mm hex wrench. Replace caps when finished to protect
motor and circuit board. Do not tighten yoke locknut at this time.
4) Rotate actuator to desired orientation. For the factory default
actuator position face the actuator circuit board and install the
actuator on the valve with the valve upright and its inlet to the left.
Thread yoke locknut onto bonnet and tighten securely. Use a blunt
chisel and hammer for final tightening.
5) Lift valve stem. Hold jamnut on valve stem and turn the stem
connector to engage valve stem. If necessary use actuator manual
override to reposition the stem connector. The valve stem should
never be turned while the plug is in contact with the seat
otherwise the seating surfaces will be damaged. The minimum
required stem engagement is 9/16 inch (14.29 mm). After required
stem engagement is reached thread jamnut up valve stem to contact
stem connector. Tighten jamnut to secure valve stem to stem
connector.
6) Install anti-rotation device on cross bar so stem connector will not turn.
7) Push red travel indicators on legs of actuator into contact with cross
bar. Connect power to actuator. On circuit board turn dipswitch 9 ON
then OFF. Actuator will perform automatic stroke adjustment. In the
stem down direction the plug must reach the seat in the valve before
the cross bar on the actuator legs pushes the red travel indicators
on legs of actuator against the actuator base. The lever extending
through the hole in the circuit board deflects to depress the upper
microswitch on the circuit board to stop the motor at that end of
travel. In the stem up direction the plug must reach the upper seat
or travel stop inside the valve before the cross bar pushes the red
travel indicators against the bottom of the motor housing. The valve
stem must not contact the bottom of the motor housing. The lever
extending through the hole in the circuit board deflects to depress
the lower microswitch to stop the motor at that end of travel. If
necessary turn off power, loosen jamnut, remove anti-rotation device
from stem connector, and repeat Steps 5 thru 7.
