Electrical Connection; Putting Into Operation - T.I.P. AJ 3 Plus 50/55 Mode D'emploi

Carefully lower the pump with the lowering rope down into liquid to be discharged. Make sure that the unit will not
bump or rub against the circumference of the cavity. The unit must be fully immersed in the liquid.
The minimum distance from the ground should be 0.5 m to prevent sludge, sand, stones etc from being sucked in.
In order to be sure of this positioning it is advisable to set the pump down on the bottom of the well shaft and to
mark this submersion depth on the tensioned cord. Make a second marking 0.5 m below this (i.e. towards the
pump). Now draw the pump upwards 50 cm and fasten the device in place at this position whilst observing the
second marking. Please note that the maximum submersion depth of the pump in liquid is 20 m.

6. Electrical connection

The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch): ∆ = 30 mA (DIN VDE 0100-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H07RN-F (3 x 1.0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splash-water-proof design.

7. Putting into operation

Nobody must be in the water while the pump is running.
The pump must only be operated in the performance range indicated on the type plate.
Dry-running - i.e. operating the pump without discharging water - is to be avoided since the
absence of water may cause the pump to run hot. This may cause considerable damage on
the device.
Please make sure that the electrical plug connections are in the flood-proof area.
As long as the device is connected to the electrical mains, one must never reach with one's
hands into the opening of the pump.
The pump must not run while the pressure port or the pressure line are closed.
Please inspect the pump visually prior to each use. This applies in particular to the mains connection line and the
mains plug. Make sure that all screws are firmly tightened, and verify the perfect condition of all connections. A
damaged pump must not be used. In any case of damage, the pump has to be inspected by qualified service
staff.
If present, open a shut-off device within the pressure line, for instance a water tap. Insert the mains plug into a
230V AC socket. The pump will start to run immediately. Shortly, the pump will start to discharge water.
To stop the operation of the pump, please pull the mains plug off the socket.
Dry-running - i.e. the operation of the pump without discharging water - has to be avoided in any case since the
absence of water will make the pump run hot. This will cause considerable damage to the unit. The main reason
of dry running can usually be found in clogged or leaking intake lines or a lack of liquid to be discharged. In this
context, please note that the water level may vary as a result of the withdrawal of water, weathering influences,
seasonal changes or other reasons. For this reason it is recommended to install an automatic water level
indicator.
The electrical pumps of the T.I.P. AJ series are equipped with an integrated thermal motor protection feature. In
the case of overload, the motor will switch off independently and on again after cooling down. For possible causes
and their elimination, please refer to the "Maintenance and troubleshooting" section.
