Connecting the pressure pipe
- Screw the pressure pipe into the pressure joint. All joint connections must be sealed with a threaded seal belt.
- You should screw the appropriate pressure hose adapter into the pressure joint when using the pressure hose.
- You should firmly screw the pressure hose into the hose adapter and fix it with a hose clip.
Please use the appropriate plumbing if it is used occasionally. It is recommended that rigid pipes with check valves be used in fixed positions. It prevents the
liquid from flowing back when the machine is shut down.
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. Put the equipment down slowly, and once the pump is submerged, it can be adjusted again.
The pump is arranged at the bottom of a liquid container, Fasten the end of the rope after lowering so that the pump can also be handled when hanging on
the rope. The pump can work after the device is connected to the main power source.
In most cases, you will be able to troubleshoot problems easily by yourself. Before you contact us, please refer to the following table for technical support.
This will help you save a lot of work and possible expenses.
Problem Reasons Solution
The pump cannot start Pump
can’t start/ stop suddenly when
running
1. Unconnected power supply/
the cut - off of supply - Defective
power cord or plug .
2. Entering the state of keeping
pressure at rest-abnormal block-
age of pipes or pumps, hot circuit
breaker cutting circuit.
3. Impeller damage causing
blockage.
4. Thermal circuit breakers cut
off due to high ambient or water
temperature.
5. The internal pressure signal
switch is failing.
1. Checking power supply/ inspection of safety devices- professional electrical
inspection.
2. You open the outlet valve. The pump will automatically open after discharge.
Removing blockage, the pump is recharged water after it is full cooled.
3. Inspection by the maintenance service.
4. Ensure that the water temperature and ambient temperature is below 35 0 C.
And it is re-electrified pumping.
5. Check the signal source in the traffic maintenance department.
Pumps are frequently opened
and stopped.
Leakage at outlet pipe or
joint-fouling clogging internal,
one-way valves leading to lax
sealing.
Maintain or replace the pipes and joints- cut off the power supply and clean the
one-way valve.
Too small flow rate
No flow of water or too small
flow
1. Insufficient water supply, not
up to impeller height.
2. Pressure tube is bent and
damaged.
3. Dirty water or particulate sew -
age reduces the flow of water.
4. Inlet blockage.
1. Increasing water supply.
2. Adjusting hose and replacing pipeline.
3.Cleaning the inlet and replacing damaged parts (e.g. worn impellers).
4. Cleaning the inlet.
The pump can not be shut down. The one-way valve in the pump is
gripped with dirt.
Inspection by the maintenance service.
The pump is not allowed to transport corrosive substances, flammable and explosive substances (such as gasoline, petroleum, nitro diluent), grease, oil, brine
and toilet equipment sewage, as well as low mobility mud sewage. The temperature of the liquid cannot exceed 35 °C.
Cleaning
Clean the equipment from the outside.
Flush with clean water. Use brush and detergent to remove stubborn pollution. Immerse the pump into a container with clean water, open it for running a
while, and flush it in the pump.
Storage
If there is a risk of frost, remove equipment and accessories, and clean and store it a place protected from frost.
Warning!
Please unplug the plug before any maintenance, and then open the outlet valve to ensure that there is no pressure in the pipeline.
Attention:
Before using the pump again, first “clean” to prevent any possible dirt residue which could affect the equipment operation.
Risk for equipment damage!
Frost will destroy electrical appliances and accessories, because they always contain water.
Disposal
Products marked with adjacent symbols shall not be treated as domestic rubbish. You must deal with these old electrical and electronic equipment separate -
ly.
Please contact local authorities to see if they can be handled properly. Make the old equipment available for recycling,processing, or other forms of second
use by separate handling.
You can avoid polluting the environment by doing so.
The packing is made of cardboard and corresponding marking plastic. These materials can be recycled.
