ACT, Inc. wireline pressure setting tools in O.D. sizes 1-1/2” through 2-1/8” do not contain a Baker style manual bleeder valve assembly (ACT pt. no. WST-2125-142) except when specifically ordered.
Two locations for bleeding pressure from tools less manual bleed valves are illustrated in drawing “A”. The preferred method of bleeding pressure is to hold wrench on “GO” 1-1/2” O.D. high pressure firing adapter while turning the setting tool counter clockwise. Pressure will begin to bleed as soon as the lower o-ring on the firing adapter is uncovered. Ample threads are provided on the firing adapter. Should a bridge occur and pressure stops bleeding, screw the tool clockwise then begin the procedure again.
The alternate method shown in drawing “A” is accomplished by holding wrench on shear sub (see parts list) while turning the top cylinder counter clockwise. The top piston will back out of shear sub and pressure will begin to bleed. Again, if a bridge occurs screw the tool clockwise then begin the procedure again.
An indication that most of pressure has safely bled off is when the tool partially closes. This indicates that the trapped compressed atmosphere in bottom cylinder is overcoming what little gas pressure remains of the power charge
