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 item can be connected within a few minutes.
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. pre-filter
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.
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 pre-filter may be retrofitted, if necessary.
A variety of high-quality pre-filters from T.I.P. is available as accessories. The range offered includes, for instance:
G5 pre-filter (item no. 31052), G7 pre-filter (item no. 31058).
The proper functioning of the filter should be checked on a regular basis. If necessary, please clean replace the
filter mesh.
11. 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.
Regular maintenance and thorough care will reduce the danger of possible malfunction and contribute to an
extension of the lifetime of your unit.
To prevent possible malfunction, it is recommended to check the occurring pressure and the energy consumption
at regular intervals. Also, the pre-pressure (atmospheric pressure) in the pressure tank should be checked
regularly. To do so, please separate the pump from mains, then open any consumer component in the pressure
line - for instance, a water tap - to release the pressure from the hydraulic system. Subsequently, unscrew the
protection cap of the tank valve (12). On the tank valve, please use a pressure gauge to check the pre-pressure.
It should read 1.5 bar, otherwise it has to be corrected.
If any water is leaking out of the tank valve, the membrane is defective and should be replaced. A high-quality,
food-proof membrane (item no. 30905) is available as a spare part.
If the device is not in use over some extended period of time, both the pump and the pressure tank should be
emptied using the devices provided for this purpose.
Water left in the pump may freeze in case of frost and thus cause considerable damage. Please store the pump in
a dry, frost- protected place.
In the case of malfunction, you should first of all check whether it was caused by an operating error or some other
reason which cannot be attributed to a defect of the device - for instance a power failure.
The list below shows some possible malfunctions of the device, possible causes and tips on their elimination. All
the measures referred to may only be carried out with the pump being separated from the electrical mains. If you
yourself feel unable to eliminate any of these malfunctions, please contact the customer service department or
your point of sales. Any repair beyond the scope specified below must only be performed by qualified staff.
Please bear in mind that all warranty claims will become void in the case of damage caused by inappropriate
repair attempts, and that we decline any liability for any ensuing damage.
