Electrical Conection; Putting Into Operation - T.I.P. HWW 900/25Plus Mode D'emploi

5.5. Using the pump for garden ponds and similar places
Operating the pump next to garden ponds and similar places is generally only admissible if no
persons are in contact with the water.
If the pump is used for garden ponds and similar places it has to be operated using a residual current circuit-
breaker (FI switch) with a nominal trigger current of ≤ 30mA (DIN VDE 0100-702 and 0100-738). Please ask your
electrical services provider whether your installation site complies with this condition.
The pump must not be used in such locations unless it is set up firmly and flood-proof, a minimum distance of two
metres away from the border of the water body and secured against falling into the water by a solid holding
device. For this purpose the device is to be bolted down firmly to the ground at the fastening points provided
(please refer to the chapter titled "Stationary installation").

Electrical conection

The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch): ∆ = 30 mA (DIN VDE 0100-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H05RN-F (3 x 1,0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splashwater-proof design.

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.
