Average water flow rate on all taps is up to 30 litres per minute the CP961® reduces this flow to (4, 6 or 8 litres per minute). It can be used on hot taps (less water = less energy to heat water).
This unit can be fitted to showers and push type taps, thus reducing the water used/wasted.
The CP961® becomes a flow regulating valve or a filter / flow regulating valve once a cartridge is inserted into the ball via the side access port.
The CP961® requires directional flow as indicated by the arrow casting stamp located near to the valve stem. If pressure testing the system with a CP961® with cartridge installed, ensure flow is only in accordance with the directional arrow. Back flow may damage the cartridge or force it out of the ball cavity.
Cartridges can be purchased separately
Before first use, a small amount of air may be trapped inside the ball seals preventing the ball from being turned easily.
Therefore we recommend first using an adjustable spanner to fully open and close the valve once.
The valve can then be operated normally with a slotted screw driver or lever (if supplied).
When installing the CP961® with ”speedfit” connection please refer to installation notes available at www.johnguest.com/makeconnect.asp.
Cartridges can be Inserted / Removed / Changed in situ under system pressure.
The valve must be closed fully before a cartridge can be removed/inserted
To remove the cartridge, first unscrew the side access port cap using a slotted screwdriver.
Using a pair of long nosed pliers; grip the steel pin and slowly lift the cartridge out.
To install cartridge, insert into side access port with the pin towards the top and push down fully into the ball. Ensure the cartridge is fully inserted. Replace the access port cap. The valve can now be opened by turning the screwdriver slot to “R”
The ball of the valve can be set at 3 different positions as below
Position C - The ball is closed and the side access port can be opened.
Position R - The ball is fully open and the cartridge is regulating the flow.
Position H - The ball is at 45º.This is for specialist use only. Contact us for details.
