My 2019 SLX7 195RBW didn't come with a bathroom fan. I can see that as a cost cutting measure, but I still think it's important to have a fan!
Having a fan will exhaust moisture from showers, cooking, etc. (as well as other bathroom related issues... )
This thread is a "how to" install a Heng's Industries 90046-CR
"Vortex II" fan.
- Phillips Screwdriver
- Slotted screwdriver
- Wire chase, small
- Wire taps
- 18" of 18 gauge double conductor wire
- Drill with 1/4" drill bit
- Remove vent opening twist knob with one Phillips screw.
- Remove vent trim (4 Phillips screws). Screen and mounting trim can now be detached. Note how flimsy they are.
- Use slotted screwdriver to detach cover of LED light fixture in bathroom. Remove 4 Phillips mounting screws and pull fixture down. This will expose the wiring.
- Drill 1/4" hole in wood framing member 3.5" from passenger side frame. This is to run the power wire.
- Use wire chase to fish two wires from vent opening to cavity above the light fixture. You should have plenty of room to fish wire through.
- Using wire taps, attach white to white, and black to purple wire.
- Replace your LED light fixture to ceiling, reversing step 3.
- On your fan, use Phillips screwdriver to relocate gear box to the outer screw mounts (2 screws)
- Support the fan near the vent opening. Using wire taps, connect white to white and black to black.
- Use Phillips screwdriver to secure fan to metal crosspiece. The two screws are short coarse thread, and are included with the fan. I looked through the screen as I was mounting the fan to line up the screws with the crosspiece mounting holes.
- Reattach your trim piece and secure with the four Phillips screws.
- Attach the gray vent opening knob with the longer single Phillips screw included with the fan.
Your installation is complete! Connect your battery and test the fan. It's important to remember that FORWARD means EXHAUST FAN (drawing air out of the trailer to the outside) and REVERSE is drawing air into the trailer.
The fan works well - at it's high setting it's a bit noisy but it draws air strongly. Overall I am pleased with the fan and I think it makes a nice addition to my 195RBW. Looks factory, doesn't it?
