1. Before using the exhaust fan + cooling pads system, please check the cooling pads and pool for debris and dust, and then shut down the fan after the pump stops for 30 minutes to ensure that the cooling pads is completely dried. After the water curtain system stops running, check whether the accumulated water in the water tank is emptied to avoid long-term immersion in the water at the bottom of the water curtain.

2. It should be cleaned 6-10 times during the annual service period. The scale and algae on the surface of the wet curtain are removed. After thoroughly drying the wet curtain, use a soft brush to gently brush up and down to avoid horizontal brushing. (You can brush a part first to check whether the wet curtain can withstand the brush.) Then only start the water supply system to rinse the scale and algae on the surface of the wet curtain. (Avoid using steam or high-pressure water to wash the wet curtain). In the season when the wet curtain is not used, a protective cover should be used to effectively reduce dust deposition.

3. The motor is the heart of the exhaust fan. If a failure occurs, the power supply should be cut off immediately and the after-sales personnel should repair it in time. Pay attention to the ground wire during installation to ensure personal safety, and be careful when disassembling the impeller to prevent the blade from deforming and colliding with the box.

4. The float valve in the pool or tank should ensure that it can automatically replenish water when the water level reaches the lower limit, and the water will be cut off when the water level reaches the upper limit; if the float valve control fails, it is found that there is water shortage in the pool or dripping at the highest water level, it should be adjusted or replaced in time . The pool must be covered and sealed to keep the water source clean, and the pool and circulating water system should be cleaned regularly to ensure the cleanliness of the water supply system. (Usually once a week) Keep the quality of the water supplied in good condition.

5. If the wet curtain water supply is insufficient or uneven, check whether there is water shortage in the pool, whether the water pump is running, whether the water supply pipeline and the water inlet of the pump can pass water, whether the small holes on the water supply pipeline are blocked, and check whether the spray Whether the water pipe is in the middle of the wet curtain. The normal spray height should be greater than 80mm.

6. Since the exhaust fan is of low-pressure type (both static and dynamic pressures are small), it is not possible to extend the pipe at the air outlet of the compressor to supply air over a long distance.

7. The circuits of the exhaust fan and water pump should be controlled centrally, and the control switch should be installed indoors.

8. When the water curtain is not in use in winter, drain the water in the pool or water tank, and wrap the water curtain and the box with plastic or cotton cloth to prevent wind and sand from entering the room.
