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-
bre
aker (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.
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.
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.
The pump is not designed for continuous operation. After a maximum of 120 minutes of running the pump must
be turned off for at least 20 minutes.
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.
8. Automation with special accessories
The present model is capable of rendering the pressure which may be required for automation, should need be. In
this context, the term of "automation" means that the liquid being discharged can be used just as if taken from the
water mains: Simply by opening or shutting water taps or consumer elements.
For automation, you will need an electronic or mechanic control system which can be installed very quickly and
conveniently. As an additional benefit, some of the control systems provide a very effective protection from
damage caused by dry-running since they will cut out the pump in the case of lack of water.
Our range of accessories contains some particularly reliable and proven control systems. For detailed information,
please refer to www.tip-pumpen.de or to your specialised dealer.
9. Maintenance and troubleshooting
Prior to carrying out any maintenance work, the pump must be separated from the electrical
mains. If you fail to separate the unit from mains, there is a risk of an inadvertent start of the
pump.
