F960968NU Cartridge Replacement Instruction


Single lever shower model Contour 21 is WRAS approved, TMV3 compliant. It has a max static pressure of 10 bar. The recommended hot supply temperature ranges from 55℃ (131℉) to 65℃ (149℉). Cold water supply temperature must be kept between 5℃ (41℉) and 20℃ (68℉). Armitage Shanks thermostatic cartridge pre-September 12, 2013, F960968NU, is the replacement part for the older model of this shower unit.

1. Remove the label index button. You can use a flat tool or your fingernail to do this.
2. Use a 4mm hex key to loosen the center fixing screw to remove the lever handle. Remove the cover plate and mouldings.
3. Slip the shroud and the spindle extension out. The head of the thermostatic cartridge is now accessible.

4. Shut off the water supply through the isolating valves. This can be done by inserting a flat-head screwdriver in the isolating valve and turning it anticlockwise. If it cannot be located, switch water supply off through the main valve near the water meter.
5. Unfasten the screw-fit cartridge using a 36mm deep A/F socket spanner.
6. Check the valve for dirt or limescale. Clean it using an old, clean rug or a small brush.

7. Layer a thin coating of silicone grease on the O-rings of the new F960968NU. Slip it in the valve housing. The recommended torque to secure the cartridge in is 15Nm.

8. Open water supplies by turning a screwdriver against the isolating valves clockwise. (If the supplies was shut through the main valve, open the main valve.)
9. Adjust the temperature if desired.
10. Refit the spindle extension and the shroud. Slide the cover plate in place.
11. Reattach the lever handle and secure it with the screw. Return the label index button.
12. Test if the installation is achieved without any problems.



F960968NU Cartridge Temperature Adjustment


F960968NU is set by the manufacturer, Armitage Shanks, at 40±1°C at a 3 bar pressure.

1. Remove the label index button and undo the center fixing screw. Open the shower mixer to the maximum position before taking out the handle.
2. Withdraw the cover plate, the mouldings, the shroud, and the grey-coloured spindle extension.
3. Slide out the anticlockwise temperature stop ring off the spindle.
4. Set the lever handle atop the spindle. Turn it anticlockwise for a hotter temperature and clockwise for a cooler temperature.
5. Once a maximum of 40℃ (104℉) to 41℃ (105.8℉) is established, slip the temperature stop ring on the cartridge. Make sure the “stop” of the ring sits at the initial point of the anticlockwise rotation.
6. Return the removed parts to assemble the valve handle. (Follow steps 1 and 2 backwards.)


What is a TMV3 Scheme?
TMV3 compliant shower mixers and thermostatic cartridges can stop water flow in 1.5 seconds in the event of water supply failure for the safety of bathers and showerers. It is mostly used in hospitals and other healthcare facilities, and in hotels.

Regulatory parameters for TMV3 are overseen by the National Health Service and other non-governmental organizations. Shower mixers and its corresponding parts are tested by third-party inspectors.


Ideal Standard / Armitage Shanks F960968NU can be shipped fast, same day dispatch, provided it is ordered on a weekday before the 3:00 PM cutoff time.
