I replaced just the fan module in our laundry room. Was wondering how difficult it is to replace the whole units in a couple bathrooms?
Panasonic makes it very easy to retrofit. Its a 3 piece system.
1. Remove the old unit (disconnect wires & duct)
2. Cut the hole bigger if needed using provided template.
3. Wire the power & re-install duct on the new module.
4. Install the retrofit brace which folds and adjusts for easy install
5. Push the Main box up and engage with power/duct module and screw to the new brace.
6. Connect the plug, set the speed (3 choices) install cover.
7. Drop a Deuce in style.
