Cautions for anti-frozen of the unit
●
① Neither the electric heating antifreeze method nor the antifreeze drainage method can
prevent freezing of the pipes and valves. All pipelines and valves from the cold water inlet to the
hot water outlet shall be wrapped with heat insulation materials to prevent freezing.
When freezing has occurred,be sure to thaw it. Make sure there is no water leakage and the unit
②
is running properly before use.
!
All adverse consequences of wall and floor damage arising from water leakage due to
failure to take any antifreeze measure will be born solely by the user.
