We'll take you through it step-by-step: from putting the housing together, sliding in the quartz sleeve, getting the globe secured and making sure it's all installed correctly. Follow these tips, and your system will be running smoothly, giving you safe, sterilised water for your entire home.
Step-by-Step Guide
1. Unbox Your Gear: First up, get your UV light system out of the box and unwrap the mounts – those are the brackets that'll hold it.
2. Unwrap the Holders: Unwrap the holders for the main housing.
3. Mount the Holders to the Wall: Fix the holders to the wall. We recommend to install it horizontally. But, if you absolutely have to install it vertically, make sure the globe/power leads go out of the top, never the bottom.
4. Clip Locks On: Pop the clip locks onto the housing.
5. Unscrew the Ends: Take off the caps at both ends of the main stainless steel housing.
6. Unwrap the Glass Thimble (Quartz Sleeve): Carefully unwrap the glass thimble.
7. Slide it In: Gently slide the glass thimble into the main UV housing.
8. Unwrap the O-Rings: You'll need one for each end of the glass thimble. Slide one onto each end. These little rubber rings will push up against the thread when you screw the end caps back on, making a watertight seal.
9. Caps Back On: Put the stainless steel end caps back on both sides of the UV system. Tighten them up as much as you can by hand. You must seal it properly.
10. Wrap the Thread Tape: Grab your thread seal tape and wrap a bit around the threads of both the 'in' and 'out' pipe connections on the UV housing. Now, connect up your water pipes to these.
11. Turn the Water On: Turn your main water supply back on.
12. Leak Check: Go flush a toilet, turn on the shower and run a few taps around the house. Have a good look at the UV system and all your new connections. Make sure nothing is leaking.
13. Turn the Water Off: Once you're sure there are no leaks, turn the water supply off again.
14. Remove the Globe (UV Lamp) from the Packaging: Carefully take the UV globe (the lamp itself) out of its packaging. Try not to touch the glass part with your bare hands if you can help it.
15. Put the Globe in: Gently slide the UV globe into the glass thimble. Take note: If you’ve mounted the unit vertically, do not just drop the globe in. You’ll likely break the bottom of the glass thimble. Lower it in carefully.
16. Power Up: Plug the controller (ballast) for the UV light into an RCD (Residual Current Device – basically a safety switch). Then, plug the RCD into your main power outlet.
17. Mount the Controller: Find a good spot to mount the controller. Make sure it's somewhere it'll stay dry and won't get knocked about.
18. Connect to the Globe: Plug the power cord from the controller into the end of the UV globe (it usually has pins that push in). Push this connection gently but firmly into the housing.
19. Put the Rubber Cap On: Put the rubber cap or boot over this connection to seal it up and keep moisture out.
20. Connect the Earth Wire: Find the little nut where the earth wire connects on the UV housing. Take the nut off and connect the earth wire securely.
21. Tighten the Earth Nut: Put the nut back on and tighten it properly. Don't skip the earth wire – it's important!
22. Cable Management: Make sure the power cord is looped or directed downwards as it leaves the globe housing. This is so any condensation that might form on the cable drips off, instead of trickling down into the globe's electrical bits.
And that’s the general flow of how your installation will go!

This guide gives you the lowdown on installing your whole-house UV light system for a rainwater tank. Start by unboxing everything, securely mounting the main housing and then very carefully fitting the delicate quartz sleeve with its O-rings to ensure it's completely watertight before you connect the pipes.
Next, you’ll connect up your plumbing, then turn the water on to do a thorough leak check around all your connections by running taps and flushing loos. Once you’re sure there are no leaks, you’ll carefully slide the UV globe into the quartz sleeve and connect the essential earth wire.
Finally, the guide covers the electrical side: safely powering up the system by plugging the controller (or ballast) into an RCD (safety switch) and then into the power outlet, making sure the controller is mounted somewhere dry and importantly, routing the power cord with a downward loop to stop any condensation from dripping into the globe's electrical connections.
Hear From Our Satisfied Customers
Why Is Horizontal Installation Recommended for the UV system, and What if I Absolutely have to Install it Vertically?
Horizontal is generally the easiest way to go and helps keep things straightforward with access and gravity. If you really have to install it vertically, the most important thing is to make sure the end where the power cord connects to the globe is pointing upwards, never downwards. This is a big safety measure to prevent any potential water from a seal leak getting into the electrical parts at the top.
The Guide Says to Do a Leak Check Before Putting the UV Globe in. Why’s that So Important?
You want to be certain there are no drips or leaks from your pipe connections or the end cap seals before you slide the UV globe in. It’s much better to find and fix a leak with just water in the system, rather than risking damage to the globe or creating an electrical hazard.
