COMMISSIONING
• As for the fixed application, please apply four screws to tighten the equipment on the foundation support firmly.
• When the equipment is used for the pound and swimming pool in the garden, the equipment shall be subject to the special setup to avoid the overflow and
falling.
• The equipment shall be installed in the well-ventilated places to avoid the weather effect.
• In case of indoor operation, please ensure that the floor is equipped with drainage ditch or leakage-proof mechanism.
• Please check the suction hose and ensure its airtightness before start-up.
• When the air foam is absorbed in the hose, the equipment is likely to be out of order because of possible leakage.
• 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 suction pipeline shall be installed by professionals.
• The inner diameter of 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 bubble.
• Please ensure that the suction pipeline has enough water supply. The terminal of suction hose shall be submerged in water all the time.
• All components of pressure pipeline shall be compressive.
• All components of pressure pipeline shall be installed by professionals.
OPERATION
The equipment can be firmly connected to the pipeline system (such as, internal water supply in families). In such case, the equipment shall apply the highly
flexible hose to connect to the pipeline system to avoid the vibration.
The equipment shall be operated only if the following conditions are met:

• 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 if it is operated without supervision.
Filling and suction
• Please fill in the pressure again when the pump starts after draining the water as time goes on.
• Disconnect the power plug.
• Open the pressure pipe to drain water completely.
• Unscrew the plastic valve in the front of pump head. The air control valve is located in the rear of the plastic valve.
• Connect the compressor hose to the air control valve.
• The filling pressure will reach up to the parameters data.
• Connect to the device again, check its function and increase the precharge pressure.
MAINTENANCE
• Attention: Please disconnect the power supply before any maintenance procedures are carried out. Risk of electric shock.
• 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 only original components. Only these replaceable components are specifically designed and produced for the equipment. When non-original
