Clean the Bypass Assembly
The bypass valve assembly should be removed only for cleaning and should be checked if
there is notable loss in system performance. No adjustment is required.To remove the valve,
turn off AC power to the unit, remove the two bolts to the bypass cover and lift out the bypass
valve assembly.
When Your Pump Needs Service
Note: Follow all warnings outlined in the “Important Safety Information” on page 3 .
• Procedures requiring disassembly of portions of the pump should be performed by
competent service personnel. Contact your local distributor or a Gasboy international
location listed on the Warranty page of this manual.
• Replace worn, rusted, or corroded parts immediately with new authorized service parts
from Gasboy. Replacing parts with incorrect or substandard substitutes will result in
unsatisfactory pump operation. Always use new gaskets or seals when servicing or
rebuilding equipment; do not re-use old ones.
Refer to “Parts” on page 17 for list of parts and service procedures for consumer electric
pumps. Using part numbers when ordering will expedite your order and reduce the possibility
of the wrong parts being shipped.
Troubleshooting
Symptom Checks Corrective Action
Pump does not start Is the breaker at the panel turned on? Replace the motor if the checks do not
solve the problem.
Is the Aux AC Control wire capped or connected to
a solenoid valve or fuel management system and
is the valve opening?
Is there power at the pump? Check at the junction
box. Voltage cannot be below 104 volts on a 115V
pump and 204 volts on a 230V pump.
Is the switch rod turning the switch on and off at
the motor?
Is motor overheated (thermal switch cutoff)?
Be careful, the external motor surface could
be hot enough to be painful or cause injury.
Let it cool down and retry.
CAUTION
Switch off the power to prevent
automatic starting of the pump when
the motor cools sufficiently.
