T.I.P. HWW 900/25 Plus Instrucciones Para El Manejo página 16

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. 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. Retrofitting with an anti dry-running feature
Booster sets from T.I.P. which are not equipped with protection against dry running, can be retrofitted when
needed. As an accessory, the quality and highly reliable dry run protection TLS 100 E is available, which can be
installed in a few steps in the pressure line (comp. Chapter "ordering spare parts").
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 3,8 bar / 3,0 bar (HWW 1200/25 / HWW 900/25 Plus) 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 prefilter 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.
On some booster sets from T.I.P. a pre-filter is included in the standard scope of delivery. On models where this
feature is not included in the standard equipment, such a prefilter may be retrofitted, if necessary.
A variety of high-quality prefilters from T.I.P. is available as accessories. The range offered includes, for instance:
G5 prefilter (item no. 31052), G7 prefilter (item no. 31058).
