Service And Disassembly; Troubleshooting - Franklin Electric VERSAJET VJ05 Manual Del Propietário

If your pump must be drained for service or to prevent
damage from freezing, remove the drain plug from the
pump case.
NOTICE: While this will drain the pump, it will not
necessarily drain all other parts of the piping system.
If there are any concerns with the proper procedure
or necessity of draining the suction plumbing,
contact your contractor.
All piping and water tanks exposed to freezing weather
should be drained. If there are any concerns with the
proper procedure to drain the systems pressure tank,
contact the tank manufacturer for assistance.

SERVICE AND DISASSEMBLY

W A R N I N G Before disconnecting pump, be sure fuse
box leads are disconnected or power is turned off at
the breaker box. After reassembling the pump, refer to
priming instructions before running.
DISASSEMBLY FOR 1/2 HP & 3/4 HP
If you experience problems with your pump,
determine the trouble from the service check list.
(TROUBLESHOOTING) If the Jet Nozzle needs
servicing, it can quickly be removed from the pump
without disturbing pump or piping. If you need to service
the impeller, motor or seal, fi rst disconnect the pressure
line from the pressure switch. Remove the bolts holding
the motor bracket to its foundation and the bolts holding
the motor to the pump case. Take off the motor and the
bracket assembly (you do not need to disconnect the
pipes if the plumbing was installed properly). This will
expose the diffuser and impeller. Unscrew the diffuser
from the seal plate to reach the impeller. The impeller
and wear ring must be removed to reach the shaft seal.
Reassemble in reverse order. Clean the seals and the
sealing surfaces in the pump case. Lightly lubricate the
rubber part of the seals with silicone grease to aid in
assembly. DO NOT lubricate the carbon or ceramic faces
on the shaft seal.
DISASSEMBLY FOR 1 HP & 1-1/2 HP
If you experience problems with your pump,
determine the trouble from the service check list.
(TROUBLESHOOTING) If the Jet Nozzle needs
servicing, it can quickly be removed from the pump
without disturbing pump or piping. If you need to service
the impeller, motor, or seal, fi rst disconnect the pressure
line from the pressure switch. Remove the bolts holding
the seal plate to the pump case (you do not need to
disconnect the pipes if the plumbing was installed
properly). This will allow removal of the motor and seal
plate as an assembly and will expose the diffuser and
impeller. Unscrew the diffuser from the seal plate to
reach the impeller. The impeller and wear ring must be
removed to reach the shaft seal. Reassemble in reverse
order. Clean the seals and the sealing surfaces in the
pump case. Lightly lubricate the rubber part of the seals
with silicone grease to aid in the assembly. DO NOT

Remedy
1. Stop the pump, fi ll it
with water, check all pipe
connections to make sure
there are no air leaks and
try again.
1. Check for proper
voltage and tight wiring
connections.
2. Check impeller and
nozzle for rocks or debris.
Refer to disassembly
instruction for getting to
impeller.
3. Check suction line
connections.
1. Pump can't pump below
25 feet. Call your Franklin
Electric dealer.
2. Use a larger diameter
pipe.
3. Check impeller
and nozzle. Refer to
disassembly instructions
above.
4. Check pipe.
1. Check to see if your
voltage is the same as
indicated on the motor
name on dataplate. Be
sure all wiring connections
are tight.
