KIT #7
Sampling Kit Stainless Steel,with QD, Dust Plug, Probe,1/4"NPT and Ball Valve,
INSTRUCTIONS FOR SAMPLING PROBE KITS - INSTALLATION
- Screw the GTP-144 probe in a ¼” NPT female thread using 1½ wraps of PTFE pipe thread sealant as a sealant and thread lube. Use reducing bushings if necessary. Wrap the tape tightly, so that it forms itself into the male thread. Do not let the tape extend beyond the open end of the fitting or fragments of the tape will get into the flow stream. NEVER screw stainless steel threads together without PTFE dope - they will gall.
- Adjust the position of the probe by tightening until the arrow on the flat of the hex is pointing downstream - in the direction of flow in the pipe.
- Install other components of the kit using PTFE pipe thread dope for each connection. Be certain that sample flow is in the direction of the arrow shaped handle of the ball valve.
- The sampling coupler is supplied with a dust plug that has a ball chain for attachment. Place the ring on the ball chain over the threaded end of the coupler before assembling.
- FLUSHING - Anew sampling connection requires extensive flushing. For best results, use the GTP-1110 Bonding and Grounding Hose to obtain high velocity in the passages of the sampling kit components.
- CONTAMINATION TESTING - Use Gammon MiniMonitor® Kit model GTP-172. Follow detailed instructions for best results. The sampling coupler can be connected without the risk of spraying fuel, if this procedure is followed:
- Slide the collar of the coupler as far as it will go toward its threaded end. Remember, the collar does not open the internal valve.
- Insert the connecting nipple in the open port of the coupler as far as it will go without depressing the internal valve, but continue to hold the collar.
- Then quickly press the nipple straight in with a force of about 25 lbs. and pull the collar back to its original position. This 25 lb. force causes the internal valve to open.
- A dry disconnection can be made simply by depressing the collar.
