5. A clogged spring case vent hole may cause the

regulator to function improperly. To keep this

vent hole from being plugged (and to keep the

spring case from collecting moisture, corrosive

chemicals, or other foreign material) orient the vent

to the lowest possible point on the spring case or

otherwise protect it. Inspect the vent hole regularly

to make sure it is not plugged. Spring case vent

hole orientation may be changed by rotating the

spring case with respect to the body. The 1/4-inch

threaded NPT spring case vent may be remotely

vented by installing tubing or piping into the vent.

6. For regulator shutdown, install upstream block

and vent valves and downstream block and vent

valves (if required), or provide some other suitable

means of properly venting the regulator inlet and

outlet pressures.

7. Apply a good grade of pipe compound to the male

pipe threads before making connections, making sure

not to get the pipe compound inside the regulator.

8. Install tubing tting or piping into the 1/4-inch

threaded NPT inlet connection on the body

(key 1) and into the 1/4-inch threaded NPT body

outlet connection.

9. The second 1/4-inch threaded NPT outlet can be

used for a gauge or other use. If not used, it must

be plugged.

10. When installing a 67CFS Series regulator in

an existing installation, it may be necessary to use

spacers to adapt the installation. If the mounting

bolts are too long, place a spacer on the bolt. To

be sure the regulator is secure, the bolts should

have at least two full threads of engagement.

1. With proper installation completed and

downstream equipment properly adjusted, slowly

open the upstream and downstream shutoff valve

(when used) while using pressure gauges to

monitor pressure.

2. If outlet pressure adjustment is necessary, monitor

outlet pressure with a gauge during the adjustment

procedure. The regulator is adjusted by loosening

the locknut (key 19), if used, and turning the

adjusting screw or handwheel (key 18) clockwise

to increase or counterclockwise to decrease the

outlet pressure setting. Tighten the locknut to

maintain the adjustment position.
