The max. system impedance of supply systems for connecting the
HWA 6000 EPF must not be higher than 0.387 ohms. If necessary,
check with your local utility provider for system impedance information.
7. 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.
The pump must only be operated in the performance range indicated
on the type plate.
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 recommenda-
ble, yet not mandatory, to vent the intake line
as well, i.e. to fill it with water.
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 firm-
ly 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 qual-
ified service staff.
