With reference to Figure 59
a. Locate the nylon tubing supplied in the kit and cut it into two equal 12-in. pieces.
b. Push one of the tube pieces into the lower fitting on the actuator assembly, making
sure it passes through the ferrule in the actuator fitting. Tighten the nut and ferrule
using a 3/8-in. open end wrench. Use a backup 3/8-in. open end wrench on the
mating piece that is screwed into the actuator.
c. Place the other end of the tubing into the valve solenoid fitting located on the outside
edge of the solenoid manifold by pushing the tubing firmly into the fitting. It should
automatically seal in place.
d. Turn the actuator gas supply on. This line should now be pressurized.
e. Verify there are no major leaks in the fittings.
Note Applying pressure to this side of the actuator will ensure that the actuator
stays in the CCW position.
f. Take the other piece of nylon tubing and place it in the upper fitting on the actuator.
Be sure the tube passes through the ferrule in the fitting. Tighten the fitting using the
3/8-inch open end backup wrench.
g. Connect the opposite end to the solenoid fitting.
Note The tubing can be released from the solenoid by pushing down on the
solenoid fitting and pulling out on the tubing at the same time.
5. Installing the actuator to the valve standoff.
a. Carefully fit the actuator into the valve standoff being sure not to rotate the valve.
See Figure 60.
