• 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 pro-
fessionally installed.
• The suction pipe should have an internal diame-
ter 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 ten-
sion 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
suction.
• Teflon tape should be used for metal pipe
threads; plastic threads must be sealed using
thread tape.
• All components of the presure 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 toilets,
washing machine, etc.
It may not be used for drinking water supply.
Electrical connection
DANGER! Mortal danger due to electric
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
provided 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 (unsupervised dry run)
will destroy the pump!
1. Unscrew water filler plug together with seal.
2. Fill completely with water.
3. Screw water filler plug and seal back in.
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 suc-
tion line.
We recommend using a suction filter for bet-
ter suction performance.

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. 23).
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.

Maintenance

DANGER! Mortal danger due to electric
shock! Disconnect the mains plug before
carrying out any work on the device.
