Troubleshooting Maintenance and Troubleshooting
The finish on Gasboy pump housings is a high-heat baked synthetic enamel, similar to that
used on automobiles. The life of this finish can be lengthened several years if, at regular
intervals, the painted surfaces are thoroughly cleaned with a high grade automobile polish
and then protected with a coat of paste wax. Do not use abrasive cleaners or polish. Do not
use high pressure spraying equipment.
In order to retain the unmarked finish on stainless steel, occasional cleaning is required. In
corrosive atmospheres, such as coastal areas, a more frequent cleaning schedule is
necessary. Under ordinary conditions, washing with detergent or soap and water, followed
by a clean water rinse, is sufficient. If hard water is used, the surface should be wiped dry
with a soft clean cloth to prevent the formation of water spots. Marks or spots, such as
grease, oily fingerprints and smudges which resist soap and detergents, will have to be
removed with a stronger cleaner. (DO NOT use ordinary steel wool as iron particles may
adhere to the surface and cause corrosion). Care should be taken in choosing a cleaner
because any cleaning compounds or powders which contain abrasives can scratch a mill-
rolled finish. Care must be exercised in their use to run in the direction of the polishing
lines in the steel, never across them. After cleaning, an application of paste wax is
recommended to protect the surface and prolong the interval between cleaning.
Troubleshooting
If problems are encountered in operation of the pump, follow the procedures below in an
attempt to isolate the problem.
Pump Does Not Start
!
Is the breaker at the panel turned on?
Is there power at pump? Check at junction box. Voltage cannot be below 104 V on a
115 V pump; 204 V on a 230 V pump.
Is motor overheated (thermal switch cutoff)? Be careful, the external motor surface could
be hot enough to cause injury. Let cool and re-try.
Replace motor if above checks do not solve the problem.
Pump Hums but Does Not Start
!
Is voltage adequate? Check voltage with pump on bypass with nozzle closed. Voltage
cannot be below 104 V on a 115 V pump; 204 V on a 230 V pump.
Check pump drive shaft for free operation.
Replace motor if above checks do not solve the problem.
