Operation

Please follow the safety instructions before
start-up!

Description of the Appliance

1 Power cord with plug
2 Connection G1(33.3mm) Suction pipe
3 Connection G1(33.3mm) Pressure pipe
4 Filling nozzle with pre-filter
5 Pressure display
6 Drain opening
7 Backflow valve

Preparing the Appliance

Illustration
 Before start-up, check the pressure of
the air filling in the storage boiler. If nec-
essary, refill up to 2.0 bar in switched off
/ zero-pressure state.
Illustration
 Secure device against slipping off (fix it
with screws, if needed).
Illustration
 Install the non-return valve.
 Connect the vacuum-proof suction
hose with integrated backflow stop on
the suction side.
(available as optional accessory)
 Connect the pressure side for noise re-
duction to the pressure pipe via flexible
hose.
Illustration
 To simplify the subsequent discharge
and pressure release of the system, we
recommend that a release cock be in-
stalled between pump and suction hose
/ non-return valve.
(not included in delivery)
Illustration
 Unscrew the lid of the filling nozzle and
fill in water till it overflows.
 Screw on the lid on the filling nozzle.
 Open existing shutoff valves in the
pressure pipe.
Note: Even the smallest of leakages leads
to malfunctioning.
 Insert the mains plug into the socket.
Caution
Pump starts running immediately. Wait till
the pump sucks in and pumps uniformly,
then shut the gate valve in the pressure
pipe. The pressure switch deactivates the
motor when the shut-off pressure is
reached. The storage boiler is now full; the
domestic water supply system is ready for
operation.
If there is a lack of supplied water, the
switch-off pressure is not reached; the
pressure switch cannot shut off the appli-
ance, the water in the pump head will then
heat up enough to damage the appliance.
In models BPP 4000/48 and BPP 4500/50,
the supplied power is interrupted by a ther-
mal switch if there is an overheated condi-
tion. The supplied power is switched back
on after the appliance has cooled off.
We recommend installing a dry run protec-
tion unit to regulate the lack of water situa-
tion.
Caution
System is under pressure!
(For pressure details see chapter on tech-
nical specifications)

 Disconnect the main plug from the
socket.
