Automation With Special Accessories; Maintenance And Troubleshooting - T.I.P. AJ 4 Plus 55/50 Gebrauchsanweisung

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 4 Plus 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.

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.
We decline any liability for damage caused by inappropriate repair attempts. Any damage
caused by inappropriate repair attempts will avoid all warranty claims.
Observing the conditions of use and the ranges of application of the present device will reduce the risk of possible
operational malfunction and contribute to extend the lifetime of your unit. Sand and other abrasive matters
contained in the liquid discharged will speed up the process of wearing and tearing and accelerate the drop in
performance.
If the unit is operated properly, it will not require any maintenance.
If the water pumped is not sufficiently clean, it may be necessary to clean the intake filter (4) with a steel brush in
order to remove the dirt that has accumulated on the outer surface. To do this the pump must be disconnected
from the electrical power supply and taken out of the water. If this external cleaning is not sufficient then the
stainless steel filter panel (4) can be removed from the pump by loosening the two Philips-head screws (fig. 3).
Then the internal side of the intake filter (4) can also be cleaned with a steel brush. The filter panel should then be
rinsed with clean water and re-fitted to the pump (fig 4). Any further disassembly and the replacement of parts
must only be carried out by the manufacturer or authorized customer support personnel, in order to avoid
hazards.
