Electical connections
The installer is responsible for making the electrical connections to the main power supply in compliance with the relevant regulations in force.
Note that international regulations demand that fixed installations incorporate a device ensuring Omni polar disconnection from the main power supply.
Make sure that the specifications on the pump rating plate and the rated line values are the same (Fig.D).
Connect the pump to an effective earth circuit and then connect up the phases following the diagram on the terminal block cover rating plate.
Check that three phase pumps stage clockwise when looking at the pump from the motor fan side, swapping over two of the phase connections if they do not.

CONDITIONS OF PROPER USE

The pump may maintain normal and continuous operation in following conditions:

1. Maximum Ambient Temperature : + 40 oC
2. Maximum Water Temperature: + 60 oC
3. Maximum Operating Pressure: 8 bar
4. Maximum Altitude + 1000m

• The pump must be earthed safely.
• The pump must be set on a dry base.
• Do not operate the pump without water.
• The pump only use for pumping clean water or liquids similar to water without sands.

OVERVIEW OF PUMPS

A. AUTOMATIC SELF-PRIMING WATER PUMP:
These pumps are equipped with automatic functions. It means that when output valve opens, the pump operates and vice versa.
B. SELF-PRIMING WATER PUMP:
These pumps have monolithic structure and self-priming function with high hydraulic performance and a considerable pressure capacity.
C. CENTRIFUGAL WATER PUMP:
These pumps with large output flow, can provide table operation and low noise; Most of pumps use for irrigation purpose.
D. PERIPHERAL WATER PUMP:
These pumps with feature of simple structure but with high head its efficiency is low.
E. MULTILEVEL WATER PUMP:
These pumps with several impellers which to be able to develop high pressure and highwater lift but with low power consumption.

• 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.
• 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.
• Always use the product with the supplied equipment. Operation of the product with non-provided equipment may cause malfunctions or even serious injury or death. The manufacturer and the importer shall not be liable for injuries and damages resulting from the use of non-conforming equipment.

INSTALLATION

The pumps must be installed in a dry well-ventilated place with an ambient temperature of not more than 40oC (Fig.A). Fix the pump in place on a solid flat surface using suitable bolts to avoid vibration. The pump must be installed in a horizontal position to ensure that the bearings operate correctly. The diameter of the intake pipe must not be smaller than that of the intake month. If the intake height exceeds 4 meters, use a pipe with larger diameter. The diameter of the delivery pipe must be chosen to suit the flow rate and pressure required at the take off points. The intake pipe must be slight angled up towards the intake mouth to avoid the formation of air locks (Fig.B). Make sure that the intake pipe is completely airtight and immersed in the water by at least half a meter to avoid the formation of vortexes. Always fit a foot valve at the end of the intake pipe. It is advisable to fit a non-return valve between the delivery mouth and flow rate adjustment gate valve to avoid dangerous water hammering in the event of the pump suddenly stopping. This measure is compulsory if the delivery water column is over 20 meters.
The pipe muse always be fitted using the related brackets (Fig.C) to avoid transmitting stress to the pump body. Take care not to damage any part by over tightening the pipes when fitting them.
Fill the pump completely with clean water before switching it on. The water should be poured in through the priming plug (Fig.F). When you have completed the operation screw the plug back in again and start the pump. The pump should be primed again whenever it has not been used for a long period of time or when air has made its way into the system.

MAINTENANCE

**** NEVER CARRY OUT ANY WORK ON THE PUMP WITHOUT HAVING FIRST DISCONNECTED IT FROM THE MAIN POWER SUPPLY. FAILURE TO TAKE THE FOLLOWING PRECAUTIONS COULD DAMAGE YOUR PUMP AND INVALIDATE THE GUARANTEE.
Our pumps do not require any maintenance provide one takes the following precautions:
When there is a risk of freezing empty the pump through the drain plug on the bottom of the pump body. Make sure your prime it when subsequently starting it again.
Check that the foot valve is clean at regular intervals.
If the pump is to remain unused a long period of time (e.g. in the water ) (Fig.G), it is advisable to empty it completely rinse it with clean water and store it in a dry place.
If the shaft does not turn freely, release it using a screw driver inserting it in the special slot (Fig.H). If this is nor sufficient to solve the problem ,remove the pump body, undoing the relevant mounting bolts, and clean it thoroughly to remove any encrustation .

ΤROUBLESHOOTING

cord connection.
Cord disconnected.
Defective motor.
Impeller stuck.
Too low voltage.| if the motor is overheated, it does not operate.
Then, wait till getting cold (20-30minutes).
Replace with a new one. insert the plug securely. Connect the cord again. Replace the new cord. Repair or replace the motor. Clean the impeller.
Consult with the power supply company.
Motor runs without pumping water.| Water level of well is lower than standard level or suction lift too high.
Trouble in non-return valve.
Filter apparatus or foot valve blocked.
Air drawn into suction pipe.
Air drawn into pump from mechanical seal.| Check the water level of well.
Move the pump closer to water intake level.
Take off the non-return valve cover, then clean the valve, the valve seat and the valve hole. Clean both of them. After checking the joints of piping, tighten them perfectly. Make sure the foot valve is immersed by at least 50cm. Replace the new mechanical seal.
Thermal protector for motor works too. often.| Too low or high power supply voltage.
Impeller is in contact with another part.
Impeller blocked.
Short or open circuit of the capacitor.| Consult with the power supply company. Check and repair the defects.
Clean the impeller.
Repair the capacitor.
Water does not come out from pump at the first few minutes after switch on.| Air drawn into suction pipe.| Repair the defects of piping. (To prevent air leaking)
