Electrical Conection; Putting Into Operation - T.I.P. AJ 4 Plus 55/50 Mode D'emploi

5.2. Installation of the pressure line
The pressure line conveys the liquids to be discharged from the pump to the point of withdrawal. To avoid
dynamic flow losses, one should use a pressure line having at least the same diameter as the pressure port (5) of
the pump.
The pressure line to be used for this application should be a suitable flexible hose - for instance, a specifically
designed drainage hose.
Rigid pipes have proven to be the ideal pressure line for use in a permanent installation.
The pump is equipped with an integrated check valve (non-return valve). It will prevent liquid from flowing back
from the pressure line into the pump after the pump is shut down and protect the unit from being damaged by
pressure peaks.
The pressure line is to be installed to the pressure port (5) of the pump.
5.3. How to position the pump
To lower or raise the pump, please use a suitable lowering rope, but never the pressure hose
or the connection cable.
To lower the pump down into or lift it out of the liquid, one has to use a lowering rope suitable for this purpose.
Please use a rope made of stainless steel or synthetic materials such as nylon. Considering the risk of breaking
involved, ropes which tend to the formation of rust, weathering, mouldering etc must not be used. The rope does
not only have to bear the weight of the pump plus that of the water-filled pressure line and the connection cable, it
also has to resist to the strain occurring in operation.
The standard equipment of this model includes a high-grade lowering rope (1).
To fasten the rope to the pump, please use the two eyelets (2) located at the upper part of the unit. Make sure
that the pump will move into a vertical position when lifted up with the rope.
The lowering rope, the connection cable (3) and the pressure line have to be tied together at distance intervals of
about 2 m using a suitable adhesive tape or cable ties to keep them from getting entangled while the pump is
raised or lowered.
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.

Electrical conection

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 splashwater-proof design.
