MacDonald Electronic Cisterns are seam welded stainless steel tanks, designed to be used in high security applications where use of flushing valves is not possible due to insufficient pipe sizes or inadequate water pressure.

CM cisterns are available in 6 and 9L capacities to suit the WC which they serve. They are designed to be installed in conjunction with either Warden or Solo electronic control systems. An externally mounted solenoid valve activates the flush valve to complete a full flush. Where dual flush is preferred, the run time on the solenoid valve can be shortened to acheive a partial dump of the tank.
Normally the tank would be installed in a duct behind a wall that the WC is mounted, however the CM-CIST6 tanks can be mounted inside the Franke FRCM-EXT extension box where a Franke combi unit is to be installed and there is no duct behind.

Refer to Warden or Solo information regarding the best electronic control system to suit your project or discuss with your MacDonald Industries representative.
