When the pipe is inserted into the air inlet and outlet, please keep the center consistent and do not connect it under forced circumstances. If shockproof joints are used for the channel hose, it can be easily connected and can prevent vibration transmission. Please do not directly add the weight of the pipe to the convex surface of the high-temperature fan to prevent deformation. When the road is drawing hot air. Please use flexible joints to avoid thermal expansion. Avoid sudden shrinkage, expansion, or bending that may result in poor fluid efficiency.

1. The power supply should use a fixed periodic wave number with a fixed voltage (recorded value on the label), and assemble the correct circuit according to the wiring diagram.

2. The voltage variation should be within 5% of the fixed voltage. (10% can also be used, but when the voltage changes greatly for a long time, it is easy to cause faults, and it is best to avoid them).

3. Due to the lack of overheating load protection device in the fan, it is impossible to monitor the heat of the fan frequently. Therefore, please install the same horsepower overload protection electromagnetic switch. And adjust the safe current to below the same value as the nameplate.

4. Select standard wiring based on the horsepower of the motor and the electrical construction method.

5. Confirm rotation direction: After the wire is completed, turn on the switch (instantly) to confirm the rotation direction and whether there is any noise. The direction of rotation is indicated by the arrow on the blower. If the rotation direction is incorrect, the order of inhaling and supplying air will be reversed. If the three-phase system is three-phase, then any two of the three external wires will be altered.

6. Grounding to prevent leakage accidents, please install a grounding wire.
