CLEANING THE OZONE INJECTOR (download PDF)

A mineral build-up in the injector is usually indicated by a marked decrease in bubbles exiting from the heater return/floor drain. Go through the HotSpring Spa Quick-Reference Troubleshooting Guide for functional or mechanical problems with the spa or ozonator before performing this maintenance.

If after going through the Quick Reference Guide you suspect that there is a build-up in the injector, refer to the following instructions. NOTE: ALWAYS CLEAN YOUR FILTER BEFORE ATTEMPTING TO CLEAN THE INJECTOR.

This is a non-warrantable maintenance procedure. You, the spa owner, should perform the procedure. Dealer performance of this service will be billed at regular service rates.
