Shall the pump continue to suck beyond the automatic cut-out level, the flow switch has to be operated manually,
e.g. by holding it in upright position. Only in this operation mode, the minimum suction height can be reached as
listed in the tec. data box. In this condition the pump has to be under constant supervision to avoid dry running.
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).
Only use an extension cable with a cable section (3 x 1.0 mm²) and rubber sheath which at
least corresponds to that of the unit's own connection cable (see "Technical data", cable type)
and which is labelled with the relevant abbreviation according to the VDE (German
Association for Electrical, Electronic & Information Technologies). The mains plug and other
connections must be splashproof.
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.
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.
To put the unit into operation, please plug the mains plugs into a 230V AC socket. If the water level has reached
or exceeded the cut-in level, the pump will start to run immediately.
To stop the operation of the pump, please pull the mains plug off the socket.
The discharge quantity can be continuously adjusted using the stopcock of the outlet element. However, please
do avoid the operation of the pump with the stopcock closed, since this can cause considerable damage.
Therefore, you should stop the pump’s operation by pulling out the mains plug from the socket immediately after
closing the stopcock.
The negligible water leakage at the lateral venting bore hole - about 10 cm below the pressure port - is inherent to
the design of the device and provides for both venting at the start-up of the pump and for temporary pressure
relief when the stopcock is closed, respectively.
The electrical pumps of the T.I.P. DIO 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.
