11.2 Motorized Valve
All units must be equipped with a motorized valve because of the following main reasons
(1) There would be a water flood risk for some units without motorized valves in the event that
they stop under the cooling conditions
(2) Under the cooling and heating conditions, energy loss would happen to the chilled water and
hot water.
Note:
●
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.
●
It is prohibited to put the valve core upside down.
●
Power supply of motorized valve is 230 V, using 24 V motorized valve can lead to its destruction.
