Maintenance Procedure - Check Valve Cartridges
Hot water entering the cold supply, or vice versa, indicates that immediate attention
is necessary. This is carried out by removing and cleaning, or renewing as necessary,
the two check valves.
1.
Turn the isolation screw on the isolator assemblies through 90
o
(refer to
Figure
4
) to isolate the water supplies to the valve. Open an outlet fitting to release
pressure and to assist the draining of residual water.
2.
Loosen the isolator grub screws and remove the isolator assemblies from the
inlet elbows.
Note!
If necessary, loosen the three grub screws that hold the valve body onto
the backplate and undo the outlet compression fitting. This is so that you can
lower the body away from the backplate. This will give enough clearance to
remove the isolator assemblies from the inlet elbows.
