② Open the back door, there is a red switch underneath the air pump. Spin the red
switch to right to drain the water and air. (
Only Rotate to right a little bit. If vavle is
opened too much the air and water will flow out very quickly while under pressure).
③ Wait until the water is drained, take out the drawer and pour away the water.
④ When the air pressure parameter in the air compressor is“0”spin the red switch
to initial position(Like photo below, otherwise the water and air will keep flowing
out)
PS: It is recommended to drain the water once in 15-30 days in humid areas and
once in 30-50 days in dry areas.
