This under-spa
skirt mounted Comet® blower
assembly needs the new motor shown on the right. It's a 1.5HP, 230 Volt
model. (To purchase this motor,

 |
 |
In order to
disassemble this kind of blower, the screws that are holding the assembly
together, must be removed. There are usually four 5/16" hex
screws. Take care to preserve the foam insulation in the
housing.
|
| MOST blowers of this type,
will utilize what is called a "strain relief" to allow the power cord
to enter the blower, and most of them, do it very well, preventing air loss
through the hole. What I'm trying to do, is to remove the strain relief,
and allow the cord to go through the entrance in the housing, so I can pull the
motor assembly out, and remove and re-attach the existing
connections. Most
strain reliefs can be removed with your fingers, simply unscrew them.
Sometimes, you may need to use a pair of pliers to get it loose.
|
|
 |
|
 |
 |
Now that the strain relief has been removed, the motor will come out
easily, exposing the wiring connections. First thing, is to remove the
ground screw connection (green wire) to the motor frame. SAVE this
screw! You'll need to use it again on the new motor.
|
 |
| Now that the ground screw is
removed, I've cut the power wires (usually black and white) to the motor,
and separated the assembly. |
|
|
 |
 |
Here I'm removing
the four screws holding the plastic motor mounting ring, (right), using a
5/16" nut driver. There's another flow isolator below this on this
specific installation, which also must be removed.
|
 |
| Motor is now totally removed... now it's
time to install the new motor in the blower assembly. |
