Watch Video
Before you start​
Ensure you have the following tools and attachments:
-
Two shifting spanners
-
Ruler
-
Marking pen or pencil
-
Hacksaw or pipe cutting tool
-
Two compression fittings (matching your supply pipe diameter and the
20mm thread on the geyser valve) -
Bucket or drip pan (to catch residual water)
Refer to the component list below
1.Shut off the water supply
Turn off the water supply to the geyser at the isolating valve(marked“3”).
​
2. Drain the geyser
Open the drainage valve (“6”). Allow water to flow into the drip tray (“2”) and out through the overflow pipe. If the drainage valve has a hose fitting, connect a hose pipe as an alternative.
​
3. Choose the installation location
Install the geyser valve before the pressure relief valve, never between the relief valve and the geyser (see diagram). Before proceeding, clear your workspace and place a bucket or pan underneath to catch any residual water.
4. Measure and mark the pipe
Mark two cutting lines 94 mm apart. Mark two centering lines 20 mm on either side of the cutting lines.
5. Cut and clean the pipe
Cut the pipe along the cutting lines (94 mm apart). Clean the ends to remove any burrs.
6. Prepare the geyser valve
Wrap PTFE tape around the geyser valve threads. Insert the rubber washers into the compression fittings. Screw the fittings onto both sides of the valve without overtightening.

7. Install the valve
Slide one compression fitting onto each pipe end. Check that the water flow direction arrow on the valve points towards the geyser. Align the fittings evenly between the centering lines.
8. Tighten the compression nuts
Hold the fitting nut with one shifting spanner. Tighten the compression nut with the other. Do not over-tighten the brass fittings.
9. Complete the installation
Ensure there is no water in the drip tray, then place the water sensor in the outlet area of the drip tray. Turn the water supply back on and check for any leaks. Ensure the drainage stop cock is closed.
10. Test the installation
Follow the test procedure on the box to confirm correct operation of the Valve. "Hold the test button in for 5 seconds. the Valve will close and then open three times, beeping after each successful test.
11. Retain documentation
Store the Smart Valve Geyser Guard box and manual next to the geyser for future reference and maintenance.
