9. Press the grip (34) onto the adjustment knob. Using the

LX Tool, screw the plug (37) into the end of the adjust-

ment knob.

CAUTION: Before screwing in the plug, turn

it counterclockwise so the threads engage

properly. Failure to do so may cause the plas-

tic threads to strip.

10. Insert the adjustment pin (31) into the end of the adjust-

ment knob. Install the adjustment knob into the valve

body. There should now be spring tension on the lever.

Continue to screw clockwise until the holes for the lock-

ing pin are clear. Install the locking pin (24). Be sure that

it sits evenly in the hole. Back the adjustment knob out

counterclockwise to apply tension on the pin and keep it

from falling out.

(19). Point the venturi lever upward and insert it into the

box bottom. Press it against the box bottom so the o-ring

is captured.

12. While depressing the lever, insert the valve body through

the venturi lever and into the box bottom. Be sure that

the two index ats and the two lever feet engage the

tabs molded into the box bottom.

13. Slide a new, lubricated o-ring (17) down the threaded

end of the valve body, into the box bottom. Slide the

heat exchanger (16), large diameter rst, down the valve

body. Thread on the retaining nut (15) until nger tight.

Using an ¹¹₁₆” crows foot or deep socket, tighten the nut

to a torque of 45 ±2 inch-lbs.

14. Fit a new, lubricated o-ring (20) onto the adjustable

crown (21). Press the adjustable crown, threaded end

rst, into the valve body. Insert a medium blade screw-

driver into the adjustable crown. Push the adjustable

crown into the valve body as far as it will go.
