INSTALLATION AND USE INSTRUCTIONS UNDER WATER PUMP MANUFACTURERWater pumps have long become indispensable equipment in many families. But the installation and how to use the pump is not everyone know.
A new water pump factory always attach a copy of the document to guide the installation and use of water pumps, but it was little attention den.De use well water pumps, durable purposes sua may bom services offer material used to pump you know about the machine.
HOW TO USE.
I. Preparation before use.
1.Noi ground wire before use to prevent the risk of electrical shock in case of improper insulation. To avoid electric shock, be careful not to be waterproof power plugs.
NOTE;
- The ground connection after a power interruption.
- Absolutely not connected to the gas pipeline because of the risk of explosion.
2. Avoid operating the pump in dry conditions and no water for the machine so that takes strength and motor may malfunction.
3. Only use the pump to pump water to pump other liquids. If you use the machine for other solvents such as benzene, acids, flammable liquids such as gasoline and other types of high viscosity, the risk of fire can occur, causing faults and reduce the strength of the machine.
4. Do not use a blanket or cloth to wrap up of the pump to avoid the cold because the machine could ignite.
5. Avoid using the machine in the blanks may be in direct sunlight or rain is wet, as this will reduce the strength of the machine and also the risk of electric shock.
6. Avoid using the machine in places with hot or cold below -100C and 400C to 400C hot water. Strength of the pump can be reduced.
7. In case the machine placed in wells MACAT can be sucked into the water with sand filtration equipment required. This device prevents the propeller pumps are not rubbing sand scratches quickly, pressure pumping weakened and reduced water quality.
8. oscillator voltage to keep the level of 10% of the available voltage. Without the strength of the machine can be reduced.
II. What to check before giving up.
Place the pump as close as possible wellhead. Where to put away the well pump, the maximum distance of the nozzle from the well to the pump suction height is calculated. Decision height depending suck dry conditions.

III. Installation instructions pump.
Choose where to place the machine how to then be able to facilitate inspection or repair.
Where to place the pump in a narrow space, the minimum distance between the pump and the walls are 30cm.
Use very little elbow to prevent water leakage à to reduce water resistance.
Cement embankment to the machine from being skewed after several years of use.
Pumps are not classified as self-priming, one-way valve should be installed at the bottom of the nozzle.
Measure the depth from the surface to the bottom of the well. Suction standard length is 8m.
Only use pipes with a diameter of normal standards.
IV. Operate.
Absolutely not operate without priming. Felt and broken blades will make the strength of the decrease.
V. Using the machine again after a long time.
The engine can not run even after turning power. The cause may be dirt accumulation and freezing in the water is pumped.
In this case, turn off the power, use a screwdriver or similar tool screw holes in the back of the motor shaft several times. Then, the pump can operate as usual.
VI. Boot
Because these pumps are not subject to automatic pump priming, the boot should priming sequence each step:
- Open the lid and fill the hopper, hopper lid. The air in the syringe will be ejected.
- Before you power on the part of the country to open the exhaust valve.
- If priming but not yet, perhaps because even the air in the syringe. For air exit nozzle pouring in, switch on and off several times power.
- For pumps without separate switch, use the power plug on the wall or plug and unplug the power cord from the socket.
