6.1
Operation
The WDC400 must be supplied with electricity from a sub main distribution board. For
major overhaul or replacement, the electrical supply to the WDC400 must be isolated at the
distribution board. To isolate the WDC400 for minor repairs, set the mains isolator switch in
the WDC400 to the OFF position. Refer to Figure 5 on page 20 for the location of the mains
isolator switch.
WARNING! Risk of electric shock, serious injury and death. Only trained and qualified
personnel should open the door of the WDC400 electronic control unit.
The basin, shower and WC are fitted with either Piezo type stainless steel pushbuttons or
infra red sensors.
Press the button face to operate a Piezo pushbutton. Once an operation cycle starts, it will
continue for a fixed period and stop unless the pushbutton is pressed again, which will
cancel the operation. The WC and shower cycle, however, cannot be interrupted in this way.
Hold your hand within 50mm of the infrared sensor to operate an infra red sensor. The
operation cannot be interrupted or stopped when infra red sensors are fitted.
The hot and cold basin valves are opened for 10 seconds each.
The hot, warm and cold shower valves are opened for 60 seconds each.
The WC flush valve is opened for a nominal period of 3.3 seconds for a 6 litre flush or
2.5 seconds for a 4.5 litre flush when a cistern is used, these cycle settings are
adjustable. The cistern refill time is set to 30 seconds.
If the WC is not a cistern type flush, but is flushed directly from the water mains or a central
tank system, the flush times may require adjustment to suit the system flow performance.
A dual flush option is available, either using one pushbutton or sensor, or using two
independent buttons or sensors. One of the two buttons or sensors is used to operate a full
flush the other for a half flush. Table 1 on page 16 gives the location of the half flush input
sockets. Refer to Table 5 on page 32 for instructions on setting a dual flush using one
pushbutton or sensor.
