CorreCTIVe ACTIoN
1. Plugged in? Check fuse/breaker or motor overload
2. Replace blown fuse
3. Reset, determine cause of problem
4. Motor will restart when cool
5. Replace
1. Replace or repair
2. Check connections, eliminate extension cork if
used, check circuit with voltmeter
3. Replace motor
Do not disassemble check valve with air
DANGer :
in tank; bleed tank
