External Air Blower Motor, Tropic-Air® Replacement Previous Page Home

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 4 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 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.
READ FIRST BEFORE YOU CONTINUE
Making a new mounting base for the blower... Quick'n Easy mounting base is complete.
This little odd-ball is a new mounting base for the blower.  It's simply made of a couple of pieces of pvc, a 2" Tee, and an end cap. 
Wiring up the blower now... Rotating the assembly to tighten the existing conduit..
Installing the blower wiring is really common sense.  Thread the wires throught the wiring compartment on the assembly, and what I'm doing here is simply rotating the blower assembly around the existing conduit, to thread the fitting back into the blower.
firmly inserting the 2 pipe into the blower housing
That completed, I insert the pvc fitting into the base of the blower.  It's a friction fit, and gets tighter as more pressure is exerted.  If possible, I like to drill a self-tapping screw into the black blower fitting, through the PVC piping.  This ensures that the blower won't 'blow itself off', of the pipe.  DO NOT GLUE THIS FITTING!
Using PeViCol to re-attach the plumbing to the new fitting 
Using a special pvc cement called PEVICOL , I plumb the old flex pvc pipe into the new blower tee.  Never use regular PVC cement to do this!  YOU WILL  cause a blower explosion, destroy the blower, and possibly cause a fire.  If you don't have PEVICOL, then you can use 2 or three deck screws to secure the hose into the plumbing fitting, or, using standard PVC cement, wait at LEAST 48 hours prior to energizing the blower!  Be sure power remains disconnected for the duration of this... and DO NOT test the blower until after the 48 hours has passed!  Otherwise you will destroy your blower using standard PVC cement!
Wiring the blower now... Job is now complete.
Finish up the project now by reconnecting the three wires the same way they were removed.  I also mount the wooden base using galvanized hanging strap material and galvanized deck screws as shown.
 
With the cover re-installed, I test the blower for about 3 seconds to ensure that it works properly, then let it sit for at least 8 hours to allow all of the silicone sealant to cure.  Testing any longer than a few seconds will cause the sealant to be pushed out of the joints, requiring disassembly and re-sealing of the blown out joints.
