Using method

(A) wet curtain water supply: first open the supply water tank water valve and the water level of the water tank exceeds a certain amount of water pump (i.e. float valve to stop water supply automatic) before it can be on the pump switch, wet curtain water began. be careful:

(1) when the water tank or the water level is not high enough, it is strictly prohibited to the pump, otherwise it will caused by pump idling fever and burn out water pump;

(2) due to the wet curtain evaporation of water consumption, so when the water pump power supply, must ensure that the normal water supply (water supply valve is in a normally open state).

(B) wet curtain water regulation

Wet curtain water supply should be the wet curtain uniform soaked up to more than 90% can be, the water flow rate through adjusting the pump relief valve opening, adjustable wet curtain of the total water supply (inverse), and the regulative wet curtain piece inlet valve opening, adjustable wet curtain of water supply (proportional). Wet curtain flow generated over the general assembly, back problems, and make the water overflow from the tank, water will cause box baffle and wet curtain flash "flying water" phenomenon; too small to make wet wet curtain.

(C) the water leakage problem

When a water drop is found, the water supply amount is too large; whether the wet curtain or the edge of the wet curtain is damaged or not, can be removed by self or by a sponge. When the water leakage of the frame interface is stopped, the water supply is stopped, and the water leakage point is dried, and the waterproof glue (glass glue) can be added.

In just opened the water supply, wet curtain is not drenched, there is a short floating water phenomenon is a normal phenomenon.
