G. Maintenance in case of long-term idle status
a) If the intelligent toilet will be idle for a long term, make sure the water in pipeline of cover is drained completely:
Disconnect the power supply, and turn off the tee valve. Push discharge button, discharge the water
inside heating pipe (with power cord).
Turn auto protection switch handle off, discharge button, discharge the water inside heating pipe
(without power cord).
With power cord
Disconnect power cord
Note:
1. If water is not completely drained and meanwhile the product is idle for a long time, the residual water may
freeze in winter or spoiled in summer.
2. If you find the water supply pipe has been frozen, do not use the intelligent cover. You need to raise the room
temperature and use it after the water is thawed.
3. When the winter temperature exceeds the normal working temperature, and there is a risk of freezing in water
pipe, please turn off the tee valve and perform one flush/or discharge the toilet.
4. When use after long term idle status, please close the tee valve and then press it again for flushing.
5. When use after long term idle status, make sure to flush it for several times and the inner pipelines are clean.
6. In case of long term idle status, remove the batteries in the charging block of remote control.
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.
