Work Instructions: How to clean a Rinnai Water Heater Filter
Preliminary Note:
- Inspect Monthly on all units and clean if needed.
Tools Needed:
- Channel Locks
Procedure:
- Turn the ball valves to your cold and hot water into the shut position. (Just the bottom ones.)
- Take channel locks and loosen the filter on the cold inlet. There will be a little bit of residual water that comes out of it.
- Rinse and clean the screens off of the filter.
- Turn the ball valve for cold water back to the open position then quickly back to the shut position. This will flush out any leftovers that may still be on the threads for where the filter goes.
- Reinstall the filter. Tighten back up with your hands. Small turn with channel locks to make sure it’s snug.
- Turn the cold and hot water ball valves back to the open position.
- Make sure the red light next to “In Use” turns back on.
- Repeat this step on the rest of the water heaters. Only do one at a time.
