Technical Data
- The manufacturer reserves the right to make minor changes to product design and technical specifications without prior notice unless these changes significantly affect the performance and safety of the products. The parts described/illustrated in the pages of the manual that you hold in your hands may also concern other models of the manufacturer’s product line with similar features and may not be included in the product you just acquired.
- Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.
- To ensure the safety and reliability of the product and the warranty validity, all repair, inspection, repair or replacement work, including maintenance and special adjustments, must only be carried out by technicians of the authorized service department of the manufacturer
WARNING! READ THROUGH THE INSTRUCTIONS FOR USE BEFORE STARTING UP THE EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock, fire, and /or serious personal injury. Persons, who are not familiar with the instructions, may not operate the equipment. Keep the instructions for use in safe custody. Children and youths are not permitted to operate the equipment.
General Safety Rules
This tool is an electric pump. It is used for pumping water and other similar water applications. After opening the package, please ensure that the products are complete. If the products are damaged or there is something missing, please do not use it and bring it back to your dealer. If you give this tool to another person, please give him this instruction manual.
- In order to operate the equipment safely, the users shall carefully read and understand the instructions before the first application.
- The users shall obey all safety instructions. Otherwise, you and others may suffer from injury.
- You shall preserve all application and safety instructions for further reference. The equipment shall be used when it has normal functions.
- Please use the equipment according to the safety and technical requirements as specified in the instructions.
- The semi-stationary and static form of the equipment is designed to be transferred to the house and garden: Spray water and make watering.
- The equipment shall be used within its performance range. Please don’t use the equipment which has an abnormal switch.
- The equipment is prohibited to be used for providing water or conveying food.
- Please don’t use the equipment in the room which contains inflammable and combustible liquid or gas.
- When the components which fail to be tested and recognized by manufacturers are improperly used, the equipment is likely to suffer from unforeseen damage.
- Any application which deviates from the intended purpose as specified in the instructions will be considered an unauthorized application, as a result, the generated problems are independent of the manufacturers.
- Please ensure that the closed equipment will not be started again by mistake.
- The equipment shall be connected to the socket which has correct installation and grounding.
- The fuse wire shall serve as the current circuit breaker when the residual current exceeds 30mA.
- Please ensure that the power supply can satisfy the connection regulations before the equipment connection.
- Please don’t bend, extrude, pull or drive the power wire to avoid the related dangers caused by line breakage.
- Please check the plug and power cable before application. When the power cable has been damaged, please disconnect the plug immediately. Please don’t use the equipment which has damaged power line.
- When the equipment is idle, please ensure that the plug has been pulled out. Meanwhile, the equipment has been closed, then, unplug the power supply.
DANGER
In order to avoid any mechanical force or tension, the suction pipeline shall be installed. When the transmission pipeline is polluted, please apply filter to make cleaning and protection.
ATTENTION
We advise installing one check valve to avoid the equipment shut-down which is caused by water absence or loss during pumping.
- All interfaces which are connected to the suction pipeline shall be sealed by hemp and thick slurry or sealing tape. The leakage will reduce the air exhaust.
- The interface of metal pipe thread shall be sealed by sealing tape.
- All components of the suction pipeline shall be installed by professionals.
- The inner diameter of the suction pipe shall be 25mm at least; The suction pipe shall be kinking resistant and suitable for the vacuum environment.
- Considering that the increasing pipe length will reduce the transmission capacity, the suction pipeline shall be as short as possible.
- The suction pipeline shall uplift the pump steadily to avoid any bubbles.
- Please ensure that the suction pipeline has enough water supply; The terminal of the suction hose shall be submerged in water all the time.
- All components of the pressure pipeline shall be compressive.
- All components of the pressure pipeline shall be installed by professionals
Operation
The equipment can be firmly connected to the pipeline system (such as, the internal water supply in families). In such case, the equipment shall apply the highly flexible hose to connect to the pipeline system to avoid vibration.
Risk for injury
When the components are unable to withstand the compression or the installation is incorrect, the pressure pipeline is likely to burst during the operation. Risk for liquid ejection!
ATTENTION
- The equipment is only used for industrial water supply, such as, toilet and washing machines and shall not be used for the drinking water supply.
- Electric shock risk: Please don’t operate the equipment in humid environment.
The equipment shall be operated only in the following conditions:
- The equipment is only connected to the socket which has protective contacts, moreover, which shall be installed, grounded and checked by professional electricians.
- The power voltage and fuse protection shall satisfy the technical data.
- The equipment shall be equipped with a protective device for less than 30mA residual current when the equipment is operated in the swimming pool, garden and similar places.
- In case of outdoor operation, the electrical connection shall be splashproof; The equipment shall not be operated in water.
- The extension wire shall have enough conductor cross-section; The cable drum shall be unfolded completely.
Risk for equipment damage!
The pump shall be filled with water when the new equipment is connected. It is
unnecessary to make up additional water during the extension operation. The
dry running of equipment is likely to damage the equipment during unmanned
supervision.
Filling and suction:
- Unscrew the pump cover.
- The pump shall be filled with water completely.
- Install the filter again and screw the pump cover and sealing elements.
- When it is necessary to shorten the suction time, please fill in the suction hose.
- Open the pressure pipeline (faucet or nozzle) to make the air escape during the intake process.
- Switch on the equipment.
- Switch off the equipment when water is exhausted evenly.
Maintenance
- Please disconnect the power supply before any operation of maintenance.
- The equipment will only fulfill the maintenance and trouble removal tasks as specified in the instructions. Other faults shall be removed by experts.
- Please apply the original components. Only these replaceable components are specifically designed and produced for the equipment. When other components are replaced, the warranty will be invalid and you and your environment are likely to be endangered.
Risk for an electric shock!
Please disconnect the power supply before any operation of equipment.
Attention:
All gaskets shall be renewed when components are dismantled.
Fault and Remedial Measures
In most cases, you will be able to troubleshoot problems easily by yourself.
