Installation

■
The power consumption of the
connected pump must not ex-
ceed 10 A, and its operating
pressure must not be less
than 1.8 bar or more than 8
bar.
■
Always switch off the pump
operated with the pressure
switch and pull the mains plug
of the connecting lead out of
the plug socket before starting
maintenance, service and re-
pair work or in the event of
faults. Protect the mains plug
from moisture.
4 INSTALLATION
IMPORTANT!
Danger of damage to the
pump!
If a pre-filter is not in-
stalled, solids can enter
the pump and cause dam-
age.
■
Install a pre-filter in the
suction line for safe op-
eration of the pressure
switch.
NOTE
The pressure switch can be installed at
any point in the pressure line.
The pressure switch must always be installed
vertically. If direct installation at the pump outlet
is not possible for space reasons, a suitable con-
nector must be used.
1. Install the pressure switch (1" male thread) to
the pressure line connection at the pump out-
let.

5 START-UP

NOTE
The pump cannot be filled via the pres-
sure switch, as a check valve is installed
in front of the pump.
NOTE
During commissioning, the pump
switches off automatically after approx.
10 s. The "RESET" (8) button must then
be pressed until the pump starts to de-
liver water. If the "RESET" button is re-
leased before the pump starts to deliver
water, the pump switches off again auto-
matically for safety reasons. Should the
priming process take longer than 2
minutes, fill the pump and suction hose
again, check the screw fittings for leaks
and repeat the process.
1. Fill pump and suction until they overflow.
2. Open a shut-off device (valve, spray nozzle,
water cock) in the pressure line.
3. Insert the plug of the mains cable into the
power socket. The pumps starts to operate.
4. Close the shut-off device in the pressure line
when water flows out of the line without
bubbles. The pressure switch switches off the
pump automatically after approx. 15 s. The
appliance is ready for operation.
