Broan AI Series Maintenance

[@jbi0150]

While removing the filter the foam side was on top but when reinstalling the filter after cleaning he installed soft side towards the bottom. Which way is correct?

[@BroanNuToneLLC]

Thank you for your question on the AI Series. The foam side should be facing away from the core or on the top.

The instructions written on the side of the core say to clean the drain pan but I don't see how to access that on my Broan HRV

Is the core washable. I have a dirty spot on mine and was wondering the best way to clean it.

Can you please share the details on how was it fixed? Me too getting this error intermittently now. Thanks

@@ysstprasanth Thank you for your question. The W22 code is an issue with the Supply Airflow. Here is some troubleshooting information: STEP 1: Unplug the unit. Perform a visual inspection of the supply damper system. Clean filters, distribution registers and outside supply hood. Inspect ducting to ensure it is not squeezed or bent. Plug the unit. If STEP 1 did not fix the problem, perform STEP 2: Remove ducting of the supply path. On the LCD screen, select MAX to check if the unit is able to reach the selected flow. If so, review the ducting path. If STEP 2 did not fix the problem, perform STEP 3: On the LCD screen, select the MIN and MAX flow setting values then reset the unit. MAX flow value will display on the LCD screen. If MAX flow is above desired MAX flow, set MAX and MIN flows. If STEP 3 did not fix the problem, perform STEP 4: Replace the supply blower and repeat STEP 3. If STEP 4 did not fix the problem, perform STEP 5: Replace the electronic assembly. Please contact Product Support directly in the US at 800-637-1453 or in Canada at 800-567-3855 for more assistance.
