Fuse Change
• Make sure the unit is off and unplugged.
• Remove screws from the back of the unit.
• The fuse is located under a small, black plastic piece on the yellow board.
• You will need to apply some pressure to open the area where the fuse is located.
• Remove the fuse.
• It may be necessary to pull slightly.
• Place the new fuse where the old one was.
• Press down until you hear it click into place.
• Close the compartment where the fuse is stored.
• When you hear it click, you will know it is secured.
• Close the back of the unit and put the screws back in place.
• Make sure to put the black feet onto the back of the unit.
•
The feet help keep the unit from rattling when it is on flat surfaces.
• The fuse has now been successfully changed.
Replacing Internal Tubes
If the diffuser stone is placed more than 4 inches deep into water, the air compressor
pressure and water pressure will equalize. If this happens, it will damage the internal tubes.
When the unit is working but does not produce ozone, you may need to unplug the unit and
open the back case to check for damage to these two internal tubes.
• Unplug the unit before beginning.
• Open the 6 screws on the back of the Aqua-6.
• Four of the screws are located under soft pads.
• The two additional screws are located in the center.
• Check inside the unit for damage to the tubes.
• If the tubes are cracked, ruptured or have become hardened, they will need to be
replaced.
NOTE:
When replacing the internal tubes, do not remove any electrical wire ties. Any loose
wires inside the unit will cause damage to the unit or will cause an electrical short.
