Open the ball valve.

Place the ratchet handle on top of the plugging 

spindle. 

Push the plugging spindle fully downwards.

Screw the plug into the fitting with the ratchet 

until bottomed-out and tight.

Test to make sure there is a seal by opening the 

bleed valve on the dome and relieving the pressure 

in the dome.

After the plug seal has been verified, pull the 

plugging spindle fully upwards (out of the 

completion plug).

Remove the dome from the valve.
