  • Page 3: General Instructions

    Dual Octo regulators that are subjected to extreme conditions such as daily use or infrequent cleaning may need service more frequently depending on inspection results. Sherwood Scuba offers a standard service kit (P/N 6000-9) that contains the parts that should be replaced at the standard service interval.

  • Page 4: Working Conditions

    Use of other tools and carelessness may cause damage to the sealing surfaces on the hose fittings requiring replacement of the entire hose. Sherwood does not recommend replacement of the o-ring at the swivel end of the hose if it does not show evidence of wear or damage.

The surface of the Demand Lever that contacts the Diaphragm should be parallel to the Housing within 1/16 inches. Place a straight edge across the Housing to check the alignment of the Demand Lever. (Refer to Illustration 1).

If the subassembly shows salt or other mineral deposits that prevent the poppet from moving smoothly, it should be cleaned as an entire unit using an ultrasonic cleaner with a mild cleaning agent. If this fails to remove the deposits, the demand valve subassembly should be disassembled by unthreading the Lock Nut (9) from the Poppet (4).

With pressure applied to the regulator assembly immerse the entire regulator to check for air leaks. Air leaks are most commonly caused by damaged or contaminated o-rings.
