The suction pipe must be tight on its entire length. Any potential leakage, e.g. on the
connections, result in air suction by the pump. In the best scenario, the pump will not
reach the declared parameters. Finally, the pump will operate without water flow,
causing its failure. Results of such a failure are not subject to warranty repair.
The direction of the suction pipe gradient must be towards the intake, so that no
syphon is present at any point that would preclude full and exact filling of the system
with water.
Prior to start of the pump or booster set, fill the suction pipe and pump with water. The
prerequisite for problem-free start is full flooding of the suction pipe and hydraulic part
of the pump. The system can be flooded through the flood plug on the suction body of
the pump or through the discharge port.
CAUTION!! Starting the pump or booster set without previous flooding results in
seizure and damage to the plastic parts of the pumping parts. This can also cause
irreparable motor damage. In such a case, only paid repair is available and no
warranty repair is provided.
After flooding, the discharge port must be connected with the pumping installation. It is
recommended to use an anti-vibration hose in a metal plain (available for purchase
from the guarantor) for the purpose of connection.
ELECTRIC INSTALLATION:
The electric network used to power the device must be compliant with data provided
on the rating plate.
The device plug must be connected to a socket with earthing. The manufacturer and
guarantor are not liable for any damage to people or property resulting from lack of
proper earthing.
The yellow-green core of the connection cable is earthing.
The powering network must be equipped with an installation, overcurrent motor switch,
e.g. M611, securing the motor against overload. In order to provide maximum overload
protection for the motor, the switch must be set to maximum coil current provided on
the rating plate. The device can operate without this protection, but in case of a failure
caused by overload, the repair costs are incurred by the user.
The powering installation must be equipped with a residual current device, with rated
making current In not exceeding 30 mA. The manufacturer and guarantor are not
liable for any damage to people or property resulting from use of power supply without
a proper switch.
STARTUP AND OPERATION:
The first start must be conducted with open taps and valves in order to pump out air
particles that could be present in the installation. The start occurs after the plug is
connected to the electric network. The taps and valves can be closed after the air
particles are pumped out. If the suction installation is tight, when the tank is filled the
booster set should reach the pressure causing the pressure switch to stop the motor.
