8 Motorized valve
All units must be equipped with a motorized valve .
There would be a water flood risk for some units without motorized valves .
The pipe must be wrapped by heat insulation material to prevent condensing water drips.
It is prohibited to bind directly the water valve wire and sponge up with the copper tube, as
there would be probably a short circuit or even electric leakage. The right way is letting the water
valve wire go through the pipe sleeve and then binding the sponge and pipe sleeve.
The unit don't supply with the motorized valve. All uses buy it themselves for their units .
