System Operation - Kärcher BPE 4000/45 Handbuch

! Do not use the power cord to carry/
transport the machine.
! To separate the machine from the
mains, pull the plug and not the power
cord.
! Do not scrape the power cord across
sharp edges and ensure that it does not
get pressed.
! Do not operate the appliance continu-
ously in rain or during humid weather.
! The voltage indicated on the type plate
must correspond to the voltage of the
electrical source.
! To avoid risks, all repairs and replace-
ment of spare parts may only be carried
out by the authorised customer service
personnel.
! Do not use this pump as an immersion
pump.
! When using the pump near to pools,
garden ponds or fountains, observe a
minimum distance of 2m and safeguard
the device against slipping into the wa-
ter.
! Follow the rules for electrical safety of
equipment:
Only operate pumps near to pools, gar-
den ponds or fountains, if they are
equipped with an earth leakage circuit
breaker with a nominal error current of
max. 30 mA. It is not permitted to acti-
vate the pump, if persons are in the pool
or garden pond.
For safety reasons, we recommend that
you operate the appliance only via a
earth-leakage circuit breaker (max. 30
mA).
The electrical connection of the system
may only be performed by a qualified
electrician. Please follow the respective
national regulations!
In Austria pumps to be used in swim-
ming pools and garden ponds should be
equipped with a fixed connection line
according to ÖVE B/EN 60555 Part 1 to
3; power supply should be via a ÖVE-
tested isolating transformer whereby
the secondary nominal voltage should
not exceed 230V.
Operations

System operation

The automatic house water system main-
tains the pressure in the mains automatical-
ly. The pump is turned on if the pressure
falls below 0.16MPa (1.6 bar). The pump
remains turned on while water extraction is
detected by the flow meter (flow greater
than 300 l/h). Shortly after water extraction
is finished, the pump is turned off. The sys-
tem is now under pressure. In the case of
renewed water extraction and the resulting
pressure drop, the pump starts again.
The pump remains turned on for a 10s pe-
riod ("overpump time") after the extraction
is finished to build up the required pressure
again. This period can be adjusted if need-
ed.
It should be increased if the pump is fre-
quently switched on and off (in the case of
reduced water extraction or system leak-
age).
Under ideal conditions, it can be reduced to
save energy.
Settings
Use the + / - buttons to adjust the overpump
time. The active light shows the current set-
ting (20s/10s/5s/3s).
In case of failure, the device is turned off
and the lights blink.
Restart the pump by simultaneously press-
ing the + / - buttons.
