Note that the purpose of this section is to
show you how to remove & install a spa pump wet end and new pump
motor. While every effort is made to be sure that virtually
all areas of complexity are covered, you may find it more difficult or
sometimes easier to accomplish this task. Use common sense. If the
wet end that you have on your spa is a lot different from what is depicted
here, then do not use these instructions. This is page 3 of this
procedure.
Safety Warnings!
| Remove Power from the spa/hot tub BEFORE performing this
procedure. Failure to comply with this requirement, can lead to
electrical shock and/or electrocution! |
Disclaimer
|
| The
instructions here are intended for general reference only. Many pumps
are different from the one depicted here, and may require more or less
mechanical effort or knowledge in order to achieve the desired
results. |

 |
| Bring the wet end to the pump
motor and insert the shaft into the impeller opening. You may be able to
start the 4 motor 'through bolts' into the wet end, but don't try to tighten
them yet. |
 |
|
 |
 |
| I use my fingers to stop
rotation of the impeller while it is tightened down. |
|
| Using a screwdriver, tighten
the armature to the impeller. It is normal to feel increased resistance
as you turn the shaft, because the pump seal will 'spring-load' against the
ceramic base seat in the housing. Once the rotation stops, don't tighten
any further. Normal rotation of the motor will keep the impeller
tight. |
|
|
 |
 |
| Now it's time to
tighten the through-bolts into the wet end housing. Don't tighten any of
them down all the way until you've at least gotten all of them started into the
threads. Once you've gotten this far, tighten all four in an X
fashion. Finally, once installed and hooked up electrically, assemble the
rear cover to the motor, and tighten the retaining
screw.. |
Assembly of the
pump is now complete.
