PREPARATION FOR OPERATION

PUMP ASSEMBLY
There is outlet hole in the submersible pump base, that is used to
attach connection and connector pipe, and then appropriate water
hose.
• Attach connection (4) by screwing it into hole in the pump base.
• Screw connector pipe (5) onto attached connection (4).
• Join water hose and connector pipe (5).
PUMP INSTALLATION
Do not use the pump in a position, when it is not supported, but
hung on water hose or power supply cable.
Submersible pump should be hung on properly constructed
support, hung on a cord or placed at the bottom of a well. Keep
bottom of the well clean and free from sludge to ensure proper
operation of the pump.
Float switch is adjusted so the pump can be switched on
immediately, when the water level exceeds 50 cm.
You can install the pump:
– to stiff pipes of a system for stationary use,
– to flexible hoses of a system.
STATIONARY PUMP INSTALLATION
• The pump must be placed on an even surface in the bottom of a
well or a tank.
• To enable appropriate operation and maintenance of the pump
in safe conditions, observe minimum required spacing between
walls and other elements when placing the pump.
• It is recommended to use pipes and connectors of the same size in
the whole water system.
• It is recommended to use non-return valve behind connector pipe
of the pump.
Dimensions of well for the pump should be minimum
65 x 65 x 50 cm so the float switch can move there freely.
CONNECTING TO ELECTRICAL POWER SUPPLY
Submersible pump is equipped with breakdown resistant
plug. In accordance with valid regulations, the pump allows
connecting to safe socket of power network with parameters:
230 V AC, 50 Hz. Connect the plug of the power cable only
to mains socket with protective prong that is connected to
electrical circuit with residual current protection IΔn < 30mA or
IΔn = 30mA.
In case the power cable or its plug are damaged, it is forbidden
to repair those parts by one's own means. Entrust repair of
power cord and the plug only to a qualified person. Only original
parts should be used.

OPERATION / SETTINGS

SWITCHING ON / SWITCHING OFF
Before connecting the pump to a power supply network, always
check that mains voltage matches the voltage shown on the
rating plate that is fixed to the pump, and that switch is in the
off position.
CHECKING SETTINGS OF THE PUMP SWITCHING ON/OFF
Float switch controls switching the pump on and off. Before starting
the pump, check the following:
Float switch should be installed so it can easily access triggering
levels (on and off ) with little force. To check, place the pump in a
vessel filled with water. Lift the float switch (2) manually, next lower
it. Doing so, note positions when the pump switches on and off (fig.
A and B).
• Ensure the connection between the float switch and the pump is
free to move and distance between the float switch and the pump
is not too small. When the distance is too small the switch, and the
pump as well, may operate improperly.
• The last thing to check is that the float switch does not reach the
bottom before the pump switches off. Such setting may cause the
pump to work dry.
When the water surface drops below defined level the pump will
switch off automatically, and when the water surface goes up and
exceeds approximately 50 cm, the pump will start operation. Thanks
to the sensor, which detects drop of water level, the pump stops as
soon as the tank is emptied.
PRIOR TO OPERATION
You can start using the pump after reading this manual carefully and
following below recommendations:
• Ensure the pump is suspended appropriately or is in stable
position on the bottom of a well.
• Ensure the pressure conduit (at the pump outlet) is connected
properly.
• Ensure the power supply parameters are 230 V AC, 50 Hz.
• Ensure the mains socket is in good technical condition.
• Ensure there is no possibility the pump operates dry.

OPERATION AND MAINTENANCE

Remove the power cord plug from mains socket before
commencing any activities related to installation, adjustment,
maintenance or repair of the pump.
Described submersible pump is a high quality and tested product,
which does not require any maintenance. The pump has been
subject to thorough and final quality check at the manufacturer's
facility. The manufacturer recommends to check the condition of the
pump regularly and carry out necessary operation activities during
the pump operation. Doing so will guarantee long and fault-free
operation of the pump.
If water level drops and sludge or other impurities get into the pump
inlet and dry up, it may cause that the pump will not start. That is
why it is recommended to often check motor of the submersible
pump (by starting up the pump to test it).
In case the pump is often transported during its life time, wash it
with clean water before each restart.
• For stationary installation, check operation of the float switch (2)
from time to time.
• Remove all fibrous impurities that may deposit in the pump casing
with strong stream of clean water.
• Remove sludge from bottom of the well, where the pump is
installed, on a regular basis (preferably every 3 months).
• Use clean water to remove deposition from outer surface of the
pump float switch.
IMPELLER CLEANING
If excessive deposition appears in the pump casing, do the following
to clean:
