Precautions; Troubleshooting Guide - Franklin Electric RLHE-300 Mode D'emploi

For Larger size motors remove rear cover and hold the
shaft using a fl at wrench inserted from the side, through
the opening in the end housing. Impeller has right-hand
thread. If impeller cannot be turned by hand, insert a
fl at object into the impeller vane.
7) Slip the rotating seal (13) off the impeller hub.
8) To replace seal seat (13A); remove bolts (10) to sepa-
rate the motor (9) from the motor adapter (2). Push seal
seat (13A) out of motor adapter (2) from motor side.
Reassembly:
1) Clean all the parts thoroughly before assembling.
2) Lightly lubricate (soapy water) the rubber cap on the ce-
ramic seal (13A) and push it into the adapter using thumbs
only. Make sure the smooth surface of the ceramic seat
faces outwards.
NOTE: If the pump will remain out of service for longer
than one week, the seal components must be installed
dry (no lubrication).

Trouble
Failure To Pump

TROUBLESHOOTING GUIDE

Cause
1) Pump not properly primed.
2) Speed too low.
3) Total head more than for which pump
was intended.
4) Suction lift is too great.
3) Put the adapter back on the motor.
4) Lubricate the rotating seal (13)(soapy water) and slip
it onto the impeller hub with the 'carbon' ring towards
the ceramic seat.
5) Replace the impeller (4) and the diffuser (3).
6) Replace the casing (1) making sure that the gasket is
not damaged and is in place.
7) Reconnect the tubes to the casing and to the pressure
switch.
8) Reconnect the power.
9) Prime pump, start, check for leaks.

PRECAUTIONS

a) Whenever pump is dismantled and then reassembled,
always check to see that the impeller rotates freely
within the diffuser.
Remedy
1) Make sure pump casing and suction line are full of water.
See priming instructions.
2) WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections and system grounding must
comply with the National Electrical Code (NEC) and with any
local codes and ordinances. Employ a licensed electrician.
Check voltage at motor terminals and at meter when pump is
operating. If low, refer to wiring instructions or check with your
power company. Check loose connections.
3) A pump designed for higher head needed.
4) Locate pump closer to source of water. Make sure suction
piping is large enough.
