6. TROUBLESHOOTING
The most common problem conditions and possible causes/corrections are described below. Please
contact the factory for assistance with other problem conditions or to discuss a specific problem in more
detail.
6.1. External leak
Possible causes:
Connection not assembled properly with Teflon tape.
Connection not tightened properly.
Correction:
Inspect equipment to determine source of the leak. Repair leak by disassembling the connection,
inspecting parts, and reassembling using good shop practice.
If the leak is from the bonnet of the regulator, then AP Tech recommends that the AK M60 manifold
be sent back to the factory for repair. However, a field repair kit is available.
6.2. Relief valve is opening and venting gas
Possible causes:
Relief valve opens below set pressure.
High delivery pressure (see section 6.3).
Correction:
Verify relief valve is opening below set pressure by checking pressure on outlet gauge. If gauge
reading is within range listed in Table 1, then remove and bench test relief valve. Replace relief valve
if defective.
6.3. High delivery line pressure
Possible causes:
Other gas source from point of use is pressurizing delivery line.
Seat leak or high creep on AK M60 crossover regulator.
Correction:
Check to see if a different gas source can be pressurizing the line.
If another gas source is not the cause of the high delivery line pressure, then it is likely the AK M60
crossover regulator has a seat leak or high creep and AP Tech recommends that the AK M60
manifold be sent back to the factory for repair. However, a field repair kit is available.
