E. Maintenance when laid up for a long period
a) If unit is left idle for a long time, the water in the unit must be drained:
Disconnect the power, close the water stop valve, hold down the drain button in front of the heating tube to
drain the water in the heating tube completely.
Disconnect the power
NOTE:
1. If the water has not been drained completely and the product has not been used for a long time, the
residual water will freeze easily in winter and become deteriorative in summer.
2. If it was found that the water supply pipeline at home has been frozen in winter, please do not use the unit
immediately; you may raise the indoor temperature, wait for its natural thawing and then use it again.
3. When reusing it after being left idle for a long time, please have it flushed for several times , so as to drain
residual water inside.
4. Take out the batteries in the remote control and the auto flushing actuator.
b) ) Open cover or add water inside the toilet might avoid the plastic parts yellowing problem caused by backflow
air from discharge pipe after residual toilet water evaporated during long-term idle status.
