Maintenance Instructions
4. Replace the Ozone Check Valve and Injector
Replacement of the check valve and the injector is required yearly for optimal performance
of the ozone generator and filter. This yearly maintenance also prevents check-valve
related failure, which can cause significant water damage to the filtration unit and the area
surrounding it.
step 1:
Using a service wrench, loosen
and remove the injector cap.
step 2:
Pull out and dispose of the
existing injector. Install the replacement.
step 3:
Loosen the nut and remove the
hose connected to the existing air-check
elbow.
step 4:
Remove the red clip and
pull upwards on the air-draw elbow to
remove it. Install the new air-draw elbow
by pushing it down into the port and
inserting the red clip until it clicks.
