Installing New Batteries

The HomePure Nova is an environmentally friendly filtration unit that is battery-operated, so it does not need to be plugged into an electric source to function. A new set of batteries usually lasts a year with regular use, so if you normally replace your filter cartridge once a year, you can also change your HomePure Nova unit’s batteries at the same time.

1. Remove the flexible pipe cover and pull off the top cover.
2. Remove the retainer ring to unlock the filter.
3. Turn on the valve and press the ejector firmly to remove the head adapter from the filter unit.
4. Place two (2) AA batteries in the battery socket found in the head adapter.
5. Reassemble the head adapter and filter.
6. Lock the retainer ring between the head adapter and the water tank firmly to avoid breakage.
7. Place the top cover back onto the filter.
8. Connect the flexible pipe to the nozzle.
   

Replacing the LED Indicator

The LED indicator is vital for monitoring HomePure Nova’s performance. When there is no LED light even though the unit is working just fine, or if the yellow light beeps even after you’ve changed the batteries, it means your LED indicator PCB set is malfunctioning and needs to be replaced.

1. Remove the flexible pipe cover and pull off the top cover.
2. Remove the retainer ring to unlock the filter.
3. Turn on the valve and press the ejector firmly to remove the head adapter from the filter unit.
4. Twist the filter cartridge to release it from the head adapter.
5. Open the battery cover and remove the batteries.
6. Remove all four (4) plastic seals from the head adapter.
7. Remove the screws that were under the plastic seals.
8. Press the ejector firmly to remove the top part from its base.
9. Unscrew the first part of the LED indicator PCB set.
10. Turn the head adaptor upside down.
11. Unscrew the second part of the LED indicator PCB set.
12. Remove the battery case.
13. Remove the LED indicator PBC set from the head adapter.
14. Attach the new LED indicator PBC set.
15. Place the battery and battery cover back in place.
16. Reassemble the top part with the head adapter.
17. Place the plastic seals back onto the head adapter to conceal the screw holes.
18. Reattach the filter cartridge to the head adapter.
19. Place the filter and head adapter back into the unit. Ensure that it locks firmly in place.
20. Reassemble the retainer ring and all other parts.
    

Replacing the One-Touch Elbow Fitting

The one-touch elbow fitting secures the connection between your HomePure Nova and water source. How do you replace a leaking elbow fitting?

1. Use a spanner to press the upper ring of the elbow fitting, releasing it from its connecting hose.
2. Place the new elbow fitting in its place.
3. Ensure that it fits perfectly with the connecting hose.
   

Securing Seal with O-Ring Replacement

The O-ring provides a tight seal for your HomePure Nova, preventing water from leaking onto the unit’s side. Replacing it is very easy.

1. Remove the flexible pipe and take off the top cover.
2. Remove the retainer ring to unlock the filter.
3. Turn on the valve and press on the ejector firmly to remove the head adapter and the filter from the unit.
4. Twist the filter cartridge to release it from the head adapter. There you will find the O-ring.
5. Remove the old O-ring from the head adapter by pulling it off gently.
6. Replace it with the new O-ring.
7. Reattach the filter cartridge to the head adapter, place the filter and head adapter back into the unit, and reassemble the remaining parts.
   

Replacing Knob Set

The knob set is basically the water switch of your HomePure Nova — set to open, and the water flows out from the unit; turned to close, the water stops. Replacing a broken knob set is very easy!

1. Use a paper clip to remove the chromium pen.
2. Unscrew the knob set to remove.
3. Replace with the new knob set by setting it into place and screwing it on.

2. Unscrew the diverter valve from the faucet and replace it with a new one.
3. Reattach the installation hose.
   

Swapping the Installation Hose

The installation hose connects your HomePure Nova to the faucet. With prolonged use, this hose may accumulate biofilm and hard calcium inside, causing the hose to clog and water to leak from it. A dirty hose like this is not good for your drinking water either, so make sure you replace it when this happens or every two years to ensure cleanliness and safety.

1. Close the faucet and diverter valve.
2. Remove the installation hose by pressing down on the upper ring of the connector.
3. Detach the installation hose from the diverter valve.
