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. Please fill the
pump housing (8) through the filling 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. HWW 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.
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. HWW 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. Anti dry-running feature
8.1.
General information
Some of the T.I.P. booster sets - more specifically, the T.I.P. HWW TLS product series - are equipped with an anti
dry-running feature. This protection system prevents the pump from damage which may be caused by its
operation with an insufficient water level or by an overheating of the hydraulic system.
8.2.
Functioning
If the temperature inside the pump reaches 60-70 °C, the anti dry-running feature will cut off the power supply of
the motor. In this way the pump will cut out, and a warning indicator lamp will light up on the terminal box.
8.3.
Resumption of operation
Once the protection system having become activated, the resumption of operation requires the switch at the
terminal box to be set to "0". Please pull off the pump's mains plug from the mains socket and allow the entire
hydraulic section to cool down. Subsequently, you should eliminate the cause of the malfunction. Then set the
switch at the terminal box to "1". Afterwards, plug the pump's mains plug into the mains socket again. If the
warning indicator lamp does not light up again, the pump will cut in. However, if the warning indicator actually
goes on again, please repeat the above steps to resume operation.
8.4.
Retrofitting with an anti dry-running feature
If required, booster sets from T.I.P. without an anti dry-running protection can be retrofitted with that feature. As
accessory the high-quality and extremely reliable optional TLS 100 E anti dry-running protection (item no. 30915)
is available, this can be connected in a matter of seconds.
9. Setting the pressure switch
Changing the preset cut-in and cut-out pressure must only be done by qualified staff.
The electrical pumps of the T.I.P. HWW series will cut in as soon as the cut-in pressure is reached as a result of a
pressure drop occurring within the system - as a rule, by opening of a faucet or any other consumer element.
Cutting-out occurs after the consumer element concerned has been shut off and the pressure in the system has
increased again to reach the cut-out pressure. The pressure switch is ex-factory set to 1.6 bar for the cut-in
pressure and to 3 bar for the cut-out pressure. Experience has shown that these values are ideally suited for most
installations. Should any modification of these settings be required, please contact your installation or electrical
specialist.
10. Operating the pump with a T.I.P. prefilter
Abrasive matters contained in the liquid being discharged - such as sand - accelerate wear and tear and reduce
the performance of the pump. When discharging liquids containing such matters, the installation of a pre-filter is
recommended. This useful accessory it will efficiently filter sand and similar particles out of the liquids, thus
minimise wear and tear and extend the lifetime of the pump.
