Note: Use a pre-filter to filter our any con-
tamination (e.g. sand, clay, etc.).
• All screw connections must be sealed with thread
tape (e.g. Teflon tape) since leaks will cause air to
be drawn in and will reduce or prevent water suc-
tion.
• Teflon tape should be used for metal pipe threads;
plastic threads must be sealed using thread tape.
• All components of the suction line must be profes-
sionally installed.
• The suction pipe should have an internal diameter
of at least 25 mm; it must be kink resistant and
suitable for vacuum use.
• The suction line should be as short as possible,
since the conveying capacity decreases as the
length of the line increases.
• The suction line should ascend steadily toward
the pump to prevent air pockets.
• Sufficient water supply must be assured; the end
of the suction line must always be in water.
Connect pressure line
NOTICE! Risk of damage to the
device! The suction line must be installed
so that it does not exert any mechanical
force or tension on the pump.
• All screw connections must be sealed with thread
tape (e.g. Teflon tape) since leaks will cause air to
be drawn in and will reduce or prevent water suc-
tion.
• Teflon tape should be used for metal pipe threads;
plastic threads must be sealed using thread tape.
• All components of the pressure line must be com-
pression-proof.
• All components of the pressure line must be pro-
fessionally installed.
DANGER! Risk of injury! If the compo-
nents are not compression-proof or if they
are improperly installed, the pressure line
could burst during operation. Risk of injury
from liquid spurting out!
Note: The device may only be used for
industrial water supply, e. g. from the toi-
lets, washing machine, etc.
It may not be used for drinking water sup-
ply.
Electrical connection
DANGER! Mortal danger due to elec-
tric shock! Do not operate the device in
wet surroundings!
The device may only be operated under the following
conditions:
• The device may only be connected to outlets with
protective contacts that have been professionally
installed, grounded and inspected.
• Mains voltage and fuse protection must comply
with the technical data.
• When operating in swimming pools, garden
ponds and similar places, the device must be pro-
vided with a residual current of not more than
30 mA by means of a residual-current-operated
protective device.
• When operating outdoors, the electrical connec-
tions must be splash-proof; they must not lie in
water.
• Extension cords must have sufficient wire cross
section; cable drums must be complete unwound.
Operation
Filling and intake [suction]
NOTICE! Risk of damage to the
device! The pump should be filled with
water after each new connection or in the
event of water loss or air intake. Extended
operation without a water refill (unsuper-
vised dry run) will destroy the pump!
► P. 4, fig. 1
1. Unscrew filter housing (7) and remove filter.
2. Pour clean water in slowly until the pump is filled.
3. Reinstall filter and screw filter housing and seal
back on.
4. If you wish to shorten the suction time, you should
also fill the suction hose (only possible with foot
valve).
5. Open pressure line (turn on water spigot or noz-
zle), so that air can escape during intake.
6. Switch the device on.
7. If water exits evenly, switch the device off and pull
the plug.
Note: We recommend installing a check
valve between the pump and suction line,
so that the water column remains in the
suction line.
We recommend using a suction filter for
better suction performance.
► Accessories – p. 27
Operation
The pump and suction line must be connected and
filled.
NOTICE! Danger of damage to the
device! The pump must not be allowed to
run dry. Sufficient conveying medium
(water) must be on hand at all times.
1. Plug in the mains plug.
2. Turn pump on at the On-Off switch.
3. Open pressure line (turn on water spigot or noz-
zle).
4. Check to be sure that water is coming out.
If the motor does not start up or the pump does not
build up any pressure or if similar faults occur, turn the
device off and try to remedy the error (► Faults and
remedial measures – p. 26).
NOTICE! Danger of damage to the
device! Do not allow the pump to run
longer than 3 min. when the pressure line
is closed. Allowing it to run longer can
result in overheating and damage.
