External Air Blower Motor, Tropic-Air® Replacement Previous Page Next Page.

Note that this section is intended for replacement of a blower "motor" only.  This requires disassembly and reassembly of the blower housing, and the connection of 3 wires.  The information depicted here may or may not match your equipment, or configuration.  It is provided for reference only.  Use common sense when working on your equipment.  If you do not understand the information provided here, then do not use it, and consult with a qualified electrician, or spa technician.  This is page 2 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!

The instructions here are intended for general reference only.  Many blowers are different from the one depicted here, and may require more or less mechanical effort or knowledge in order to achieve the desired results.
installation of the new motor installation of the new motor
Installing the new motor is quite easy at this point, simply maneuver the wiring and the motor through the access hole in the motor mount.  Be careful not to damage the brush assemblies.
assembly prior to securing... mounting the motor...
On the left, we've got the motor and mounting assembly sitting in the correct position.  On the right, we're re-installing the 5/16" screws that will hold the assembly together.
Now we've got to thread the motor wires to the connection compartment.  First I  trim them to the appropriate length, and thread them through the housing.  (This may seem odd, but I only do this as a demonstration in case the wires in your particular blower configuration are too short.  Check yours first before cutting the new wires).

Using small wire nuts to ensure a good connection...  
With all of that completed, connecting the wires and setting every thing else electrical wise is in order now.  The 3 wires coming from the main compartment must be connected to the blower motor. Don't forget the ground wire! attaching the ground wire to the motor frame..I usually prefer to twist them together, connect a wire nut, then tape them up with electrical tape.  Then, to prevent the blower air from untwisting them, tie the entire group of wires together with a nylon tie-wrap.
first tape the wire connections, and the wire nuts! ...using a nylon twist tie to secure everything together.

Cleaning up the wiring....  
Because the electrical connections are in the same compartment/area as the rotating armature, it is important to make sure that everything in this area is minimalized.  The least amount of wire, means the least amount of problems.  Using a nylon tie wrap to prevent the unravelling of the electrical tape, and keeping the wire assembly intact is important here.  Use common sense!

If the wires on your blower motor are long enough, you may not have to perform this patch, simply route the new wires through the housing.  Don't forget the ground wire though!
