Putting Into Operation - T.I.P. HWA 3000 INOX Gebrauchsanweisung

8. Putting into operation

Please observe the illustrations, too, which are contained as an attachment at the end of the present operating
instructions. The numeric and other details included in brackets below refer to these illustrations.
Prior to putting the pump into operation for the very first time, the pump housing
should be fully vented - i.e. filled with water - even in the case of self-priming
units. If this venting is omitted, the pump will not suck in the liquid to be
discharged. It is highly recommendable, yet not mandatory, to vent the intake line
as well, i.e. to fill it with water.
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. Moreover, this means that very hot water will be enclosed within the system so that
there is a hazard of scalding. If the pump has run hot, please pull off the mains plug and allow
the system to cool down.
Please do not expose the pump to moisture (e.g. when operating sprinklers). Do not expose
the unit to rain, either. Make sure that no dripping connections are located above the pump.
The pump should not be used in wet or moist environments. Make sure that the pump and the
electrical plug connections are arranged in a flood-proof place.
The pump must not be running with the feeder line closed.
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.
Each time the pump is put into operation, please make sure that the pump is set up securely and firmly standing.
The unit must always be positioned upright on an even surface.
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.
Prior to the first time the pump is put into operation, the pump housing (8) has to be fully vented. Therefore, fill the
pump housing (8) through the filler opening (9) completely with water. Please check to make sure that no leakage
occurs. Subsequently, close the filling opening airtight again. It is highly recommended to vent the suction line (2)
as well, i.e. to fill it with water. It is true that the electrical pumps of the T.I.P. HWA series are self-priming and can
be put into operation by filling only the pump housing with water. In this case, however, the pump will require
some time before it will have sucked in the liquid to be pumped and proceed to the actual discharging function. In
addition, this way of proceeding may require the pump to be filled several times. This depends on the length and
diameter of the suction line. After filling, please open any shutting device (7) in the pressure line, for instance a
water tap, to enable the air to escape during sucking in.
Plug the mains plug into a 230V AC socket. The pump will start running immediately. As soon as the liquid is
being discharged evenly and without air mixture, the system is ready for operation. You may then close the shut-
off valve in the pressure line again. The pump will cut out upon reaching the cut-out pressure.
In the course of the first put into operation it may be possible under certain circumstances that the electronic
pump control will switch the pump off and the red „Error" warning indicator will light up. As a rule, this is caused by
the fact that the amount of air within the system was too large at the first intake cycle, thereby causing the anti-
dry-running feature to trigger. In this case, please press the "Start pump" button on the electronic pump control to
put the unit to operation again (please cp. „Functioning of the electronic pump control" section). This step may
have to be repeated several times until the first intake cycle is completed and the system is vented. Prior to each
pressing of the start button, please make sure that switching off was not the result of some other cause which
must be eliminated prior to each new start.
If the pump was out of operation for some extended period of time, the steps described above have to be
repeated for a renewed putting into operation.
The electrical pumps of the T.I.P. HWA 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.
