Set toggle switch
- A change-over switch is a device that can be steplessly adjusted. For this, you first need to loosen the screws. The position control height of the switch water can be set by stepless adjusting the length of the power line.
- Please check the following items before the pump starts running:
- A float switch must be installed so that it is easy to switch between the ON and OFF switching points. This should be checked, and the floating switch should be carefully picked up and put down again. When you do this, pay attention to the switching status of the switch.
- Ensure the distance between the top of the floating switch and the switch line card buckle is not too small. If the distance is too small, it cannot guarantee normal work.
- When you set up the float switch, make sure that the switch does not touch the base before the pump is opened. Warning There is a risk of dry running.
- Set the switch to automatically control the height of the water level by adjusting the position of the float switch cable at the card line.
- Please check the following items before the pump starts running.
- The float switch must be clamped at the card line so that it can normally float, control, turn on and off. This should be checked, and the floating ball switch should be carefully picked up and put down again. When you do this, pay attention to the switching status of the switch.
- Ensure the distance between the top of the floating switch and switch line card buckle is not too small. If the distance is too smalI, it cannot guarantee normal work.
- When you set up the float switch, make sure that the switch does not touch the base before the pump is opened. Warning There is a risk of dry running.
Attention: Risk for equipment damage!
- Do not lift the pump by cable or pressure hose, because these cables or pressure hoses are not designed for tensile strength from pump weight.
- The float switch must be able to move freely and the submersible pump cannot be used in a dry environment.
- For rope handling: Do not operate the pump without the pressure hose to prevent the pump from twisting around its longitudinal axis.
- In continuous use of a pump with a rope, the condition of the rope must be checked periodically, as it may break with increasing use time.
OPERATION
Connecting pressure pipe
- screw the pressure pipe onto the pressure connector. All joint connections must be sealed with a threaded sealing stripe.
- When using the hose, screw the right hose adapter into the pressure connector.
- Secure the hose firmly to the hose adapter and secure it with a hose clamp.
- If it is used occasionally, please use a suitable pipe. A rigid pipe\ with a check valve is recommended for use in a fixed position.
- This can be done at the close of the machine to prevent liquid backflow.
Use a strong rope to connect the handle of the pump and dip it into the liquid to be conveyed at a certain angle, so that the lower side of the device has no bubble formation to prevent the bubbles from being sucked in.
