User Manual

Q: Is this a disposable unit?
A: This is not a disposable unit, UV lamps have a life span of 6 - 9 months in constant use. However, it is only suggested for use with green water and unit shall be switched off if water is clear. If the LED indicator on the control box is OFF, it means you will have to replace the UV lamp assembly (AA09W-UVC or AA24W-UVC). Just like any other UV sterilizer, the bulb itself is disposable. The difference between AA and other brands is that we replace the lamp together with its housing, so we make sure the seal is 100% and easy for users. Prices for these replacement bulbs are very affordable. 

Q: Why is the flow rate so slow?
A: Slow flow rate together with our ZIGZAG flow design (inside the housing) are to maximize sterilizing it.

Q: Can you make the sponge bigger? I have to clean it every 2 days.
A: The UV sterilizer is not an internal filter. You can try to put the UV sterilizer near the outlet of your existing filter, where the water is cleaner. If this doesn’t help, we recommend you to clean your filter media and make sure it filters sufficiently.

Q: How comes my bulb looks old with dust all over it?

A: If you notice a slight whitish powder on the surface of your Green Killing Machine, simply rinse it off. This powder is due to the special high-performance plastics we use that withstand the intense UVC bulb in the Green Killing Machine.
