10. FEATURES AND FUNCTIONS
1) There is an indicator light at the end of pressure switch. The meanings of the indicator
lights are as follows:
1 Light on Pump is working
2 In the status of dry-running protection
3 Light off Pump is off
2) Pressure adjustment
The pressure screw can be rotated in order to change the set value of the pressure switch.
5HPRYHWKHFDS
SUHVVXUHVFUHZ
• The pump cannot stop after closing the tap. The set pressure can be decreased by counter-
clockwise rotation of the pressure screw until the pump is able to stop.
• The pump cannot start after opening the tap. The pressure can be increased by clockwise
rotation of the pressure screw until the pump is able to start.
3) Function
1 Automatic start -
cally work.
2 Automatic stop 6 to 8 seconds after the tap has been closed, the pump will
stop.
3 Dry-running protection Close the water inlet when the pump is working. The pump
will have the following performance: the pump runs for 8
minutes and then stops for 30 minutes; it runs for 8 minutes
and then stops for 30 minutes; it runs for 8 minutes and then
stops for 30 minutes. After 8 minutes of running time, the
pump is permanently in the shutdown state, at that time, the
pump is in the dry-running protection status. By opening the
water inlet, there are two ways to terminate the dry-running
protection:
1. Switch the pump off and on again.
2.
dry-running protection.
- 12 -
4 Power off, automatic restart The pump could quickly restart and return to the working
condition when power is switched on (after it has been
switched off).
5 Anti-blocking function The pump runs automatically for 2-3 minutes if it has not
run in the last 24 hours to make sure that the pump does not
block.
11. PIPE ASSEMBLY AND CAUTION
1) The pump must be installed according to the installation drawing (Fig. 2).
2)
The pump must be installed as close as possible to the nearest water source so that the suction
line is as short as possible to reduce suction loss.
3) The electric pump is to be installed in a dry and well-ventilated place and must not be
exposed to the sun or rain.
4)
The inlet pipe of the pump must not be higher than the inlet (Fig. 3).
5)
The pump suction pipe must be immersed 30 cm below the water level to prevent air from enter-
ing the pipe due to the vortex formation. It must be 30 cm higher than the water bottom so that
no soil or other objects enter the pump.
6) If the pump does not have a self-priming function, a non-return valve must be installed.
To prevent water return, it is recommended to install a non-return valve.
7) The pipe connection must be well sealed and made with on-site raw materials and sealants.
If the inlet pipe is not well sealed, the suction will be directly affected, or the water cannot
rise; some problems may occur, for example, abnormal operation, and the water cannot rise.
8) Try to reduce the bend in the pipe circuit as much as possible. The gradient should be less
than 2%.
9) The pipes should be supported separately at all times. They must not be supported by
the pump.
10) It is recommended to install a suction strainer on the inlet to prevent sand and sundries
entering the pump which can damage the pump.
- 13 -
12. INSTALLATION AND NOTES
1) The pump must be installed by a professional institution and licensed electrician.
2) The voltage and frequency must be in accordance with
3) The pump should be reliably earthed, and a leakage
protection switch must be installed.
4)
The wire must meet the requirements of the current. Due
to wire line losses, the voltage is too low to perform normal
pump work.
A larger wire diameter must be used, or the
length of the wire reduced, which will result in reduction of
wire line loss.

15. MAINTENANCE
The pump does not require any special maintenance. However, after using the pump in
low-temperature areas, water in the pump body must be drained in order to prevent freez-
ing of the water, which may result in bursting of the pump body. If the pump is not used for
a long time, it should be cleaned and kept in a dry place.
