2. Installation
1. Place the machine in a horizontal position and on a sturdy-resting place. Keep
the pump level and install valves on the inlet and outlet of the pump for easy
maintenance.
2. If the pump must be installed outdoors, it is essential to provide adequate
covering, especially if the pump is equipped with an electrical switch.
3. Sunlight will weaken PVC pipes. Please install it with ample protection from direct
sunlight.
4. Choose heat resistant pipes if the temperature of the solution is above 60°C.
5. Before connecting tubing to the pump, the tubes should be washed to remove any
extraneous matter there may be such as welding pellets, cut-off from gaskets, etc.
6. Make sure that the tubes are perfectly sealed and that the air is not inltrating the
pump by any means.
7. If metallic pipes are used, make sure that a vibration absorbing is connected to the
pump to avoid damage to the pipeline or the pump.
8. If the elevation of the outlet pipe reaches beyond that of the pump, please install a
check valve near the pump to prevent damage from back-pressure.
9. Install a foot valve to protect the pump from sucking in impurities.
10. Do not exert any extraneous forces on the pipe such as twisting or bending. After
installation is complete, please look over the pipes to make sure that none of the
pipes is warped due to excessive force.
11. Make sure that the pump and pipeline are sturdy and well leveled after
installation.
12. Make sure that the power, voltage, and frequency are suitable for the motor
before wiring, and install a circuit breaker.
13. Put a protective cover over the pump when it is used for pumping dangerous
liquid.
14. Make sure that the pump is lled with uid, and all the valves are opened before
starting the motor.
15. Please make sure that the inlet connecting ange is equal in diameter with the
inlet ange, and the outlet-connecting ange is the same size as the outlet ange.
When mounting the pipes onto the pump, we suggest applying 8~9Nm of torque
on 12mm bolts for the inlet and applying 8~9Nm on 12mm bolts for the outlet.
Please also note that the inlet connecting ange should be equal in diameter with
the inlet ange and the outlet-connecting ange should be the same size as the
outlet ange.
16. The pump is marked with 230 VAC, 50 Hz, however it could be used with higher
voltage, as in industrial power supply. The wire connection diagram could be found
in the connection box on the motor.
17. Use an electromagnetic switch. It wills automatically cut-off the power supplies if
the motor is overloaded.
