Operation And Maintenance; Operation / Settings; Technical Parameters - VERTO 52G449 Manual De Uso

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:
• Unscrew connector pipe (5) and connection (4).
• Use stream of clean water to clean impeller, casing interior and inlet
holes (3).
• Follow specified actions in reverse order to assemble all parts.
All faults should be repaired by service workshop authorized by the
manufacturer.
