Introduction
Thank you for purchasing this quality product. To minimize the risk of injury by means of fire or electric
shock we urge that our clients take some basic safety precautions when using this device. Please read
the operation instructions carefully and make sure you have understood its content.
Always use a grounded power connection with the appropriate mains voltage. You can find the corre-
sponding mains voltage on the type plate. If you have any doubts about the connection being grounded,
have it checked by a qualified professional. Never use a faulty electric cable.
Do not inspect the electrical part of the pressure pond filter in a wet or damp environment or when you
are wet yourself and protect it from direct sunlight. Install this device in a safe location so that nobody
can step on the cable, fall over or damage it. Make sure additionally you provide sufficient cooling
through the ambient air and avoid heat accumulation. Disconnect the power plug before cleaning it and
use only a damp cloth for cleaning.
The electric part of the device contains no parts that can be inspected or serviced by the user. Leave
the maintenance, adjustment and repair to qualified technical personnel. In case of unauthorised inter-
vention the 2-year warranty is no longer valid! Keep these operation instructions safe.

Safety guideline
BEWARE:
The use of this device is allowed on standing bodies of water, garden ponds’ water or swimming ponds
and their surrounding areas only with fault current protection-switch with a triggering nominal current up
to 30mA (according to VDE 0100 Article 702 and 738).
The device is not intended for use by persons (including children) with impaired or limited physical,
sensory and mental abilities or lack of experience and/or real knowledge, unless they are supervised by
a person responsible for their safety or you follow the instructions made by this person how to use the
device correctly.
Children should be supervised to make sure that they do not play with the device.
ATTENTION:
•Run a visual inspection of the device before every use. Do not use the device if the safety
appliances are damaged or worn out. Never override safety regulations.
•Use the device exclusively according to the intended purpose stated in the instructions for use.
•You are responsible for the safety of the working environment.
•If the cable or the plug is damaged due to external influences the cable must not be repaired! It
has to be replaced with a new one. This work can be carried out only by an electrician.
•The voltage indicated on the type plate of the device of 230 Volt alternating voltage has to
correspond to the existent mains voltage.
•Never lift, carry or fixate the device by using the power cable.
•Make sure that the electrical plug connection is placed in a flood-proof area and is protected
from moisture.
•The user is responsible for the compliance with location specific safety and installing regula-
tions. (Ask an electrician).
•Consequential damage arising from flooded rooms caused by dysfunctions of the appliance
must be avoided by means of the appropriate measures. (installing an alarm system, reserve
pump).
•In case of malfunction the repair work can be carried out only by a qualified electricial or the
WilTec-service.

Functional description for the general operation of the pump control:
The pump control consists of a pressure switch and a water flow switch. The switching cycles are then
determined from the two switching states of the pressure switch and the water flow switch.
1. Water pressure switch actuated + Water flow switch unactuated = Normal shutdown (delay of ap-
prox. 3-8 sec. To shutdown).
2. Water pressure switch unactuated + Water flow switch actuated = Pump on
3. Water pressure switch unactuated + Water flow switch not actuated = Switch-off due to drying and
indication for fault. (Delay 8-15 seconds)
Common causes of malfunctions:
1 Problem:
The pump control switches off and displays failure / failure even though water has previously been
pumped successfully. After a reset, this error reappears immediately or after a short time.
Possible causes:
A: The water pressure of the pump used is not sufficient to actuate the water pressure switch. (Causes
may be a clogging, a worn pump body, or a too weak pump)
B: The water pressure switch in the pump control is blocked / blocked. (Cleaning with clean water can
solve the problem or the housing of the pressure switch in the pump control must be cleaned, and
sand and other sediments may have deposited here.)
2. Problem:
The pump control permanently activates the pump regardless of whether the tap is open or closed.
Possible causes:
A: The installation of the pump control has not been considered. This does not reset the water flow
switch and is permanently actuated. (Check the installation and correct if necessary.
B: Water flow switch in the pump control input is permanently actuated. This can be caused by con-
tamination, calcification or a foreign body. (An optical test confirms this problem and can be cleansed
by cleaning.)

If the water head between
the pump and the highest
point of the water pipe ex-
ceeds 15 meter, the device
cannot be installed directly
to the pump. The unit must
be brought (mounted) at
such a height, so that the
protruding water pipe is
shorter than 15m. For ex-
ample: if the water pipe is
20m long, the device must
be mounted at least 5 m
higher above the pump.
The pump control is
equipped with a test valve,
to protect the pipe system
against pressure loss
Between the pump and the
pump control no taps are al-
lowed.
Pump pressure
The device is set at a pre-
pressure of 1,5 bar. The
pump pre-pressure must be
normally 0,5 bar higher than
the cut-in pressure, so it
must reach at least
2 bar.
Before starting the device
check the suction hose and
the pump filling!
Pumpenfüllung
prüfen!
We recommend
the user to connect the
pump control with the
water pipe supply,
through a flexible
hose.
The safety valve to
prevent water leaking
in case the membrane
breaks or bursts (do
not change or modify)
The pump control has
to be oriented upwards
according to the arrow.
The device can be in-
stalled directly to the
pump or between the
pump and the first tap.
