Bettis does not recommend periodic field maintenance for the M11S-S module and pump.
The only time the M11S-S module or pump should be disassembled is when either the
pump or the M11S-S module fails to perform its override function. If maintenance is
required and when possible the M11S-S package should be returned to the factory for
maintenance.
