1. Assemble the air fittings onto the solenoid valve as

shown in the following figure.

2. Stop the pump at the middle of its stroke.

3. Relieve pressure. See the SmartWare Shot Dis-

pense Kit Instructions-Parts manual for pressure

relief instructions.

4. Disconnect the air line to the air motor.

5. Remove the air motor top cover using a flat head

screwdriver.

6. Remove the screw on the outer valve cover to

remove the cover.

7. Remove the ten screws from the valve cover to

remove the cover, spring-loaded detent, and gasket.

8. Remove both end cap retainer pins from their holes.

9. Invert the retainer pins and slide the heads into the

slots on the existing piston stop valves. Use the

retainer pins to pull the piston valve stops out.

10. Install a new piston valve stop (1), o-ring (14), and

elbow fitting (20) in the top of the valve body. Apply

a liberal amount of lubricant (17) to the o-ring before

installation.

11. Install a new piston valve stop (1), o-ring (14), and

straight fitting (15) in the bottom of the valve body.

Apply a liberal amount of lubricant (17) to the o-ring

before installation.

12. Install the solenoid bracket (2) to the top of the valve

body using the two mounting screws (10) and wash-

ers (11).

13. Install the solenoid valve assembly (3) to the sole-

noid bracket using the two solenoid valve screws

(12).

14. Connect cables and air lines as shown in FIG. 8. Cut

air line tubes to length.

NOTE: To avoid kinks in air lines when connecting them

from the solenoid valve to the piston valve stop, use

large radius bends in the air lines and support tubing

with the supplied cable ties.

NOTE: For supply systems, ensure there is enough

cable and air line tubing to allow for full ram extension.

15. Reassemble air motor. Follow steps 6 through 3 in

reverse order.

16. Tee into your existing air supply, upstream from any

regulators, to provide air to the solenoid air supply.

Ensure there is a minimum of 70 psi (0.49 MPa, 4.9

bar).

1. Assemble the air fittings onto the solenoid valve as

shown in the following figures.

NOTE: Use the following table to determine which figure

corresponds to the air motor used by your system.

2. Stop the pump at the middle of its stroke.

3. Relieve pressure. See the SmartWare Shot Dis-

pense Kit Instructions-Parts manual for pressure

relief instructions.

4. Disconnect the air line to the air motor.
