Safety Precautions
To ensure normal and safety operation of the electric pump, read the
manual carefully before use.
The electric pump should have reliable grounding to prevent short
circuit; for safety, leakage protection switch should be equipped and
be careful not to wet the power plug; socket should be connected in
damp - proof area.
Do not touch the electric pump while working; do not wash, swim
near working area or let livestock into the water to avoid accidents.
Avoid splashing pressured water to the electric pump as well as
prevent the pump immersed by water.
Acquaer Ltd. H-4900, Fehérgyarmat, Szatmári út 11.
Keep the pump in ventilation.
In case ambient temperature is lower than 4℃ or the pump is not
used for a long time, empty liquid the pipeline system to avoid ice
cracking of the pump chamber.
Do not operate the pump for a long time without water in it.
The pumped liquid maybe hot and under high pressure, before
moving and demounting the bump, valves in both sides of the
bump should be turned off first and then empty liquids in the
pump and pipelines so as not to be scalded.
Do not transfer any inflammable, explosive or gasified liquids that
beyond the stipulation.
Ensure the pump will not be accidently turned on while installing
and maintaining; if not used for a long time, cut off the power first
and then turn off valves in inlet and outlet of the pump.
Power supply should be in accordance with the voltage stated in
the nameplate. If not used for a long time, put the pump in dry,
ventilated and cool place under room temperature.

Pipeline Installation
This product should be installed and maintained by personnel who is
proficient in this manual and has special qualifications. Installation and
operation should be in accordance with local regulations and recognized
operation standards.
Install pipelines properly as stipulated in the manual and meanwhile conduct frost
protection measures for the pipeline.
For the installation, the inlet
pipe should be as short as
possible with the least turnings.
The pump should be installed in
ventilated and dry environment.
It could be installed outside,
provided having proper covering
to prevent rain and wind.
For pipeline use, valves should
be installed on inlet and outlet
pipelines and the inlet pipeline
should be installed with check
valve.

7. Valve
B: Installation precautions for inlet
pipelines
1. While installing the electric pump, do
not use too soft rubber tube for the
inlet pipeline, avoiding to be sucked
flat.
2.
The foot valve should be vertically
placed and installed 30cm from
water bottom to avoid sucking in
sands and stones (B2)
3.
Joints of the inlet pipelines should
be
sealed with the least elbows; no
water can be sucked.
4. Diameter of the inlet pipe should be
at least in accordance with that of
the water inlet, to avoid too much
water loss which will influence
outlet performance.
5.
Pay attention to drop of water level
while using, the foot valve should
not be above the water surface
(B1).
6.
In case the inlet pipe is longer than
10m or its lifting height exceeds 4m,
the pipe diameter should exceed
diameter of water inlet of the pump.
7.
Ensure the pumped will not be
affected by pipeline pressures
while installing the pipelines.
8.
Filter should be installed in inlet
pipelines so as to avoid solid
particles to pump.
C: Installation Precautions of the
outlet pipeline
Pipe diameter of the outlet pipeline
should be at least in accordance with that
of the water outlet, so as to reduce its
voltage drop, high flow rate and noise to
the minimum.

Electrical Connection
Unless the power is off, do not wiring the junction box.
The electric pump should have reliable grounding to prevent current
leakage with leakage protection switch being equipped.
Electrical connection and protection should be conducted according to stipulations.
Specification of working voltage is marked on the nameplate; please ensure the
motor is in accordance with power supply.
In case the working area of the electric pump is too far from the power supply, power
transmission lines should be of a heavier gauge, otherwise the electric pump cannot
work normally because the voltage drop is too dramatic.
A rubber extension cable shall be applied for the electric pump in case of outdoor
use.
Check rotation of the motor (three-phase motor).
Check whether operation of the electric pump is normal, rotation is correct, which
could be observed from the fan blade terminal, e.g. clockwise rotation means
correct direction. In case the rotation is incorrect, cut off power and exchange the
two power cables.
Acquaer Ltd. H-4900, Fehérgyarmat, Szatmári út 11.
Start-up and Maintenance
Do not start up the pump before the pump chamber is filled with
water.
Do not touch the electric pump unless its power has been cut off
for at least 5 minutes.
Do not dismount the pump body unless water in the pump chamber is emptied.
Rotate the fan blade before
start- up, check whether the
pump rotation is flexible and
then unscrew the water-filling
plug, fill the pump chamber
with clean water from the
water injection hole, then
tighten the plug screw after
the air has been completely
discharged. The valve should
be shut tightly while starting
up the pump. After the pump
discharges water and
operates normally, adjust the
valve to the required flow
(working range is displayed
on the nameplate).
Attention:
In case no water is discharged after being started for more than 5 minutes with
water filled, turn off the electric pump, re-fill water or check whether the inlet pipeline
has leakages
In case of any frost and ice damages, please open the drain plug to empty
water in the pump chamber. When start up the pump again, open the drain
plug, fill water and tighten it and then the pump is usable.
In case not use for a long time, water in the pump should be emptied. The
pump body, impeller and support should be cleaned and coated with
anticorrosive oil before they are put in a ventilated and dry place for use.
In case the pump is halted for a long time, start it up again according to
above diagram.
In summer or when the ambient temperature is high, pay attention to
ventilation, avoid dew on electrical parts which will result in electrical faults.
In case the motor is hot or abnormal, cut off the power immediately and
check faults according to the following table.
