 ■ Attentions

1.Working ambient temperature:-40℃--120℃, should try to avoid close to three-element catalytic, gas discharge pipe system and engine during the installation, ensure the working environment temperature.
 
2.The installation position of the water pump should as much as possible close to the low water level , to extend the service life of the pump.
 
3.Please use the pump far from the dusty environment, the dust is harmful to reduce the service life
 
4.Pay attention to the purity of the water, avoid to jam and impeller-blocked to reduce the service life of pump
