Installation precautions of outlet water pipes (Fig. 3)
Diameter of outlet water pipes should be at least the
same as that of water outlet to minimize pressure,
Choice of installation location (Fig. 4)
When installing pumps, inlet pipelines should be
as short as possible and elbows should be as few
as possible. Pumps should be placed in the well-
ventilated environment. Pumps may be installed
outdoor, but they must be covered to prevent rain
damage and frost.
MAINTENANCE MANUAL
When there is no water detected by the pump it will
enter dry run protection. This consists of 3 cycles of
100 sec "ON" and 5 sec "OFF". If no water is
detected after 20 seconds on the final cycle the LCD
screen will display a flashing "ERR" and " "
symbol. To reset pump, disconnect from main power
supply and reconnect.
The pump will stop when the water flow stops. When
there is water flow the pump will start automatically,
this is determined by a drop in pressure in the pump
head.
When there is low water pressure for a long period
of time the pump will enter into a pressure check
mode. The pump will start and stop up to 6 times
within a 2 minute period. The pump will stop after 1
hour in this mode and will display a flashing "ERR"
on the LCD screen.
To enter clock settings press and hold "Menu"
button for 5 seconds.
CLOCK SETTINGS
Display screen will flash hour first.
Press "D" button to change the hour, then
press "Menu" to change to minutes use "D"
to set minutes.
After setting minutes press "Menu" again to set
AUTO ON TIME
and
AUTO OFF TIME
repeat the
same methods as
setting clock
.
Do not use a soft rubber hose as it may collapse
during the operation of the electric pump.
Bottom valve must be vertical and 30cm above
bottom to avoid debris being picked up.
All water pipe joints must be sealed with minimal
elbow connections for best performance.
Monitor water level decline when using, and bottom
valve should remain submerged.
Ensure that the water inlet pipe matches the electric
pump inlet pipe diameter.
For additional protection it is recommended to install
in line filters.
Before use ensure that the screw plug for water
drainage has been installed correctly.
Set inlet water pipes (Fig. 6)
Water pumps are connected with circuits:
Steel wire hose or corrugated pipe (2);
Removable connection nut (3);
Water inlet (4);
Correct operations are as follows: Connect (3) to (2)
(Fig. 6) prior to connecting (3) to (4) (Fig. 6). Ensure
that all connections are sealed correctly.
Set outlet water pipes (Fig. 7)
Installation of outlet water pipes is shown as Fig.7,
the same as installation of water inlet pipes; pay
attention to sealing of pipelines.
Pump operation
1. Fill the suction hose with water. Unscrew the filter
cap (2), then fill the body of the water pump
slowly (2-3 liters) until the water comes out through
the water inlet (1). (Fig. 8)
2. Connect the suction hose to the water inlet (1).
(Fig. 9)
3. Connect the discharge pipe with the water outlet
(3)
The pump will start when the switch is turned on.
Clean strainer mesh (Fig. 9)
Clean strainer mesh (Fig. 9)
To maintain optimum water flow performance, users
should clean strainer mesh components regularly
according to water quality. The method to clean is
as follows:
Strainer mesh is rotated as the direction of arrow in
Fig.10 to separate strainer mesh; clean strainer
mesh respectively with clean water; assemble
strainer mesh and install them properly for use.
If there is any risks of damage due to frost or
freezing, or electric pumps may not be used for
a long time, please open screw plug for water
drainage to discharge water. When pumps are
needed to restart, open pump cover, filled with
water and tighten cover before restart.
Tips:
adjust head height. Once the parameter is set press
and hold "Menu" to return back to normal operation.
