2. Mechanical installation
2.1 The pump can be installed vertically or horizontally mounted (see figure 1 ) When installed
vertically, the outlet port should be upward .
2.2 In order to avoid the dry- running (air get stuck in impeller),the water pump outlet port should
be vertical or in the upper of the impeller. (see figure 1 )
2.3 The connected pipe should be vertically mounted (or no elbow in 20cm )to make the air
discharged easily, the outlet pipe should not be used less than 90 degrees elbow (see figure 2).
2.4 Can't use the seawater or other heavy pollution with big grain impurity liquid as the liquid
medium .
Electrical Interfaces:
3.1 Recommend PWM/CAN Communication Connectors and Pin Port Description:
Manufacture:TE Connectivity(Recommend)
Connector Model:AMP282106-1
Matched Plug Model:AMP282088-1
3.2 Non-Recommend Connectors:
For the application of water pump with lead wires, JUNQI International can replace the connector
types as the customer request. Or 2pin connector for fixed speed (on/off), 3pin connector with feedback
function (or 3pin PWM communication application), please contact with us for your request details.

4.3 CAN Communication:
Please communicate and obtain the recommendation agreement when selecting the design!4.4 PWM
Communication(Recommend)
4.4.1 Water Pump Connector Pin port definition(figure3, figure4)
1. Please add a fuse in the water pump power supply circuit to cut off the power supply when appearance the failure.
2. Avoid the water pump is covered or blocked and affected by the surrounding devices heating. The installation space is convenient for maintenance and replacement operation.
3. 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
4. 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.
5. Pay attention to the purity of the water, avoid to jam and impeller-blocked to reduce the service life of pump
6.Please use the pump far from the dusty environment, the dust is harmful to reduce the service life
