1. GENERAL WARNINGS
- Read this manual carefully before
installing this pump. It contains every
necessary information for installation, correct
use and maintenance of AQUALIJU pumps.
- It's very important that the user reads this
manual before using the pump. Any damage
caused by failure to observe the directions
contained in this manual will not be covered
by warranty.
- By the time you receive this
pump check if it wasn´t damaged
during transpor-tation.
- In this case, please contact our agent
as soon as possible.
2. DANGER - ELECTRIC SHOCK RISK
- Do not use in ponds, tanks or swimming
pools when people may enter or come into
contact with the water.
- Make sure that the pump is
switched off before installation or
maintenance operations.
- The unit must always be earthed in
accordance with local legislation.
- Never use the electric power cable to suspend
or transport the pump.
CAUTION !
- If the electric cable or has become damaged
please contact our agent before any
intervention with the pump.
3. OPERATING CONDITIONS
- Pumps from AQUALIJU series are
suitable for:
- Clean water with a maximum temperarure
of 35º C and a maximum sand content of 60
3
g/m ;
- Minimum internal diameter of well: 115
mm AJ.
- Minimum immersion depth: 200 mm;
- Maximum submersion depth: 20 m (with
suitable cable length);
- Maximum starts/hour:
30 at regular intervals.
- The electropump cannot be used
to move dangerous or inflammable
liquids.
5.1. EARTH CONNECTION
fig. 1
- The pump must be earthed before
any other operation, even if the
delivery pipe is a non metallic one.
- This pump is not for portable use.
- Switch off this pump every time you transport it.
- The earth connection is also useful to reduce the
risk of galvanic corrosion due to electrolytic action
especially with non-metallic delivery pipe and safety
rope.
4. INSTALLATION:
- Never use the electric power
cable to suspend the pump;
- Avoid dry running.
4.1. PUMP INSTALLATION IN THE
R E S T I N G P O S I T I O N
(TANKS):
- The pump can be rested on the flat botton
surface of a tank, but when sand or particles of
sediment are present it's advisable to mount
the pump on a surface raised from the bottom
level so that abrasive matter is not lifted.
4.2. PUMP INSTALLATION IN THE
SUSPENDED POSITION (WELL):
- The pump can be held in a suspended
position by the metal delivery pipe.
- Tighten the threaded pipe joints firmly to
avoid loosening during operation.
- Position the pump at a distance of at
least 0.5m from the bottom of a well so that
sand is not lifted (fig. 1).
- When a plastic or flexible delivery pipe
is used, a nylon safety rope or chain should
be utilized for lowering, securing and
raising the pump.
- Attach the power supply cable to the
delivery pipe and to the safety rope with
cable clamps at intervals of about 3 m.
- The power cable should not be taut. It
must allow a certain degree of slackness
between the clamps to avoid the risk of
strain caused by expansion of the pipe
during operation.
- Protect the electric power cable from
contact with the well wall to prevent
damage.
5.2. RESIDUAL CURRENT
PROTECTION DEVICE:
0,5m
WARNING: It is advisable to install a
gate valve at the pump output to avoid
deposition and a check valve easily
reachable to allow easy pump removal in
cleaning and maintenance operations.
- Single phase pumps are supplied with
a float switch that watches the water level
avoiding drops below the suction strainer.
- For three-phase pumps we recommend
the installation of a control box with a
water level protector and its electrodes.
5. ELECTRIC CONNECTION:
- The electric connection must be
carried out by a qualified electrician.
- Single phase pumps equipped with
capacitor must be connected as shown in
fig. 2.

EARTH
- It's advisable to install a
height capacity switch (0,03 A)
with complemental protection
against electric discharges in
case of ineffective earthing.
- Make sure the frequency and mains voltage
correspond with the pump data;
- The electric connection must include a
multipolar switch or other disconnection
device from the mains with a minimum contact
separation of at least 3mm on every polles.
5.3. AQUALIJU 230V:
- Single-phase pumps are suplied with an
incorporated capacitator and a thermal
protector so that the motor will stop if
overheating is detected and with automatic
start up (after cool down 2 to 4 minutes).
5.4. AQUALIJU 400V:
- Three-phase pumps must be connected to
the power supply line through a control box
equipped with:
- water level protector with its respective
electrodes to prevent the pump against dry
runnig;
- frequency protetor against phase lack;
- thermal protector gauged for the motor mains
voltage.
6. STARTING:
- Never run the pump dry, not even
for a short trial run.
- The minimum immersion depth at
first start-up must be at least 200mm.
ENGLISH
- Do not start up the pump with a
completely closed shut-off gate valve.
- Never take the pump out of the
water while it is still operating.
- With a three-phase power supply make
sure the direction of rotation is correct.
- The correct direction of rotation will
provide a considerably greater pressure and
delivery capacity.
- If it's not correct switch off the power, invert
the connections of two phases on the control
panel, restart and check the pressure or flow
rate capacity again.
- The pump shall operate within
its range of rated performance and
the absorbed current indicated
must not be exceeded.
7. MAINTENANCE:
- Under normal operating condictions
the pump will not require maintenance.
- If the pump is temporarily used with
dirty liquids or water containing
chloride, flush the pump briefly with
clean water immediatly after use to
remove any deposite.
- If the pump has not been used for a long
time and does not start or gives no water
(but electrical connections are in order),
the pump must be removed from the
water and checked to see if it is choked
by any foreign matter or blocked by
sediments, deposits or any other cause.
The products , referred to in this statement are in
accordance with Directive 73/23/EEC (the Low
Voltage Directive). Full compliance with
essential requirements of the Directive is
verified for compliance with standard EN
60335-2-41.
8. PROBLEMS, POSSIBLE CAUSES AND SOLUTIONS
Caution! These operations must be carried out by specialized personnel.
Before performing any service operation, be sure that the unit is disconnected from the elctric power supply.
PROBLEM
The electropump does not
pump water. The motor
does not run.
The motor runs but the
electropump does not pump
water.
The electropump stops after
running for a short period of
time because one of the
termal motor circuit breaker
trips.
POSSIBLE CAUSE
-
No power.
Motor protection tripped.
-
Demaged capacitator.
Shaft blocked
-
A solid object is blocking the impeller.
-
The pump is sucking air.
- The pump rotates in the wrong direction
(Three-phase pumps).
- Suction grid blocked.
- Check valve blocked.
- Low voltage.
- The power supply does not
correspond with the data on the
nameplate.
- The pump has run without liquid.
SOLUTION
- Check the voltage.
- Verify the cause and reset the switch. If the
thermal circuit breaker has tripped wait for the
system to cool down.
- Replace the capacitator.
- Verify the cause and unblock the
electropump.
- Disassemble the hydraulic part and verify if
the impellers rotate freely.
As electrobombas Aqualiju,
referidas nesta
declaração, estão em conformidade com a Directiva
73/23/CEE (Directiva de Baixa Tensão). A plena
concordância com os requesitos essenciais da
Directiva é comprovada pela conformidade com a
norma
EN 60335-2-41.
- Make sure that the joints are air-tight.
Check that the liquid has not dropped below
the minimum level.
- Invert the electric phase connection of
rotation.
-
Clean the suction grid.
Clean or replace valve.
Use electric cables of larger diameter.
- Check the voltage on the power supply
cables leads.
- If the pump is equipped with a float switch,
verify if this is functioning working it manualy.
Reestablish the water level before restart the
pump.
If in spite of carring out the above operations the problem still persists contact the nearest service centre.
