Cleaning and Maintenance

Not in use for an extended period of time
If the water heater is not used for an extended period of time, please carry out
the following steps:
1
Turn off the water pipe valve.
2
Screw the water drainage pipe to the safety valve's pressure-relief hole;
turn on the safety valve handle.
3
Turn the hot water valve to the maximum (at the same time unscrew the soft
sprinkler pipe from the water outlet valve; take care not be scalded by hot
water), drain the inner chamber of water.
When the water heater needs to be used again, our recommendation is to open
hot water valve before switching on the power in order to prevent accidents.
Allow any gas that may be trapped in the pipe to be discharged. Do not smoke
or allow other exposed fire to be near the opened valve. At the same time, make
sure to carefully examine all the parts of the water heater and ensure that they
are in a perfect condition. Make sure to fill the inner chamber with water before
use.
