SAFETY INSTRUCTIONS

Attention: Please read this manual and all the instructions it contains before using the pump.
• Before submerging the 6HC series motor into a well, the motor should be filled with clear water.
• Before using the water pump, ensure that the working area is properly grounded. Earth leakage protective devices as well as overload or over-current
protective devices must be installed on the water pump.
• Ensure that the electric pump will not dry run.
• When the pump is in operation, persons and animals must be prevented from touching the water near the pump.
• In order to prevent electrical shock, the power source shall be shut off during maintenance and cleaning operations.
Conditions to be met for proper use
• The voltage fluctuating range shall be ±10% of rated values.
• The water temperature shall not exceed 35 ͦ C .
• The pH value of water must be between 6.5 and 8.5.
• The solid contents in the water shall not be larger than 0.25% with the maximum diameter not being over 2.3mm.

INTENDED USE

The deep-well pump is a water lifting tool that is designed to fetch underground water from deep wells or rivers, reservoirs and canals etc. Further, this product
is mainly used for farmland irrigation as well as for human and animal drinking water in mountainous areas. In addition, the deep-well pump can be used for
water supply and discharge in cities, factories, railways, mines and construction sites.

INSTALLATION AND USE INSTRUCTIONS

General notes
Please check whether the inner diameter conforms to the minimum diameter of water pumps before buying and installing. If it is a new well, an air compressor
or old water pump shall be used to clean sundries and soils. After that, please ensure that the water quality and temperature conform to the conditions listed
in the section "Conditions to be met for proper use". The water pump can only be installed with the water inside the well up to standard.
After unpacking the pump, please inspect it for damage that may have been caused during the transportation and storage process.
Ensure that the cable and plug are intact and that joints are not loose or leak.
If the pump is found to be damaged, please contact professional personnel to repair or replace it.
During the installation process, please fix the electric pump and then install an earth leakage protective device or over-current protective device correctly.
The electric pump must be connected to the ground reliably.
When the water pump reaches a certain length, the motor and pump body need to be packed separately.
Installation
In case of a separate packing,first remove the filter screen and cable protection plate from the pump body (Figure1 ), then place the pump body on the motor to
make the spindle head of the rotor smoothly slide into the coupling, manually rotate the coupling to check if it can run normally, then screw up the connecting
bolt (Figure2), and finally install the filter screen and cable protection plate (Figure3).
