d.  Loosen, but do not remove, the screws holding down the drill guide.   Slide 

the drill guide off those screws and repeat step 1b for the other set of 
screws. 

e.  Open the corresponding valve. 

f. 

Repeat steps 2a through 2c. 

Step 3 

a.  Loosen the screws holding down the 

drill guide, remove it, and empty the 
chips from the muffler.  Wipe away any 
chips that may have fallen on top of 
the base.  Place the slider plate over 
the screws with the side containing the 
O-rings facing the base.  Slide it into 
position so the alignment pins are in 
place and it sits flat against the base.  
Tighten the screws so that the slider 
plate is firmly mounted to the base. 

b.  With the flow arrow in the correct 

direction, insert the probes into the two 
holes of the slider plate.  Expect some 
resistance as the probes make their 
way through the O-rings.  Continue to 
push in until the probes make contact 

with the closed valves.  At this point any leakage noted in step 2c should go 
away. 

Step 4

 

a.  With one hand firmly holding the top 

assembly, use the other to rotate each 
valve 90° to its open position.  Push 
the top assembly into place until you 
hear an audible ‘click’, letting you know 
the two latches are now firmly in place 
and it is safe to let go.  You can expect 
approximately five pounds of force at 
the meter’s maximum pressure rating. 

b.  To complete the installation, there are 

two safety screws that will need to be 
placed in the side of the top bracket 
next to each latch.  Screw both in until        
they bottom out.
