1 General
1.1 Guarantee notice
If the instructions contained in this operator’s manual are not observed then any claims un-
der guarantee shall be void.
1.2 General
All parts coming into contact with media are designed for water quality to DIN 19643.
This counter-current swimming system is of state-of-the-art technology.
This manual does not take into account local regulations, the observance of which is the
responsibility of the operator – also on behalf of installation personnel that may be invol-
ved.
The performance label specifies the machine series, the frame size, the most important
operating data and the serial number. Please be sure to quote it in case you require more
information and also when placing subsequent orders or ordering spare parts.
1.3 Usage Instructions
The counter-current system was designed for use in private swimming pools. Consequent-
ly it must not be installed in public swimming pools. Neither the entire unit nor parts thereof
must be used in other systems. You are expressly directed to use it only in accordance with
these instructions.
The counter-current system must not be operated beyond the parameters stated in the
technical data (3.1) . In case of doubt, please contact your customer service or the manu-
facturer.
2 Safety Instructions
2.1 General
• Prior to starting up, make sure that the operators have read and understood the
operator’s manual. Not the operator but the owner is responsible for safety!
• Make sure that the relevant safety regulations and laws are observed in the operating
company and / or country where the counter-current systems are to be used.
• All parts that come into contact with the medium are resistant to an absolute salt con-
tent of up to 0.75% (4,500 mg/l Cl-). If the salt concentrations are greater than this, the
manufacturer must be consulted.
• Use the counter-current system only if it is in perfect technical condition, in accordance
with the regulations, observing safety requirements and danger conditions and strictly
adhering to all the instructions in the operator’s manual!
• Promptly remedy any faults that could influence safety.
For more details of safety instructions please see the operator´s manual
WK (27220).

2.2 Symbols
In these operating instructions the following symbols are used to draw your special atten-
tion to dangers:
Notices attached directly to the counter-current system , e.g. the arrow indicating the di-
rection of rotation, must always be observed and maintained in a clearly legible condition.
2.3 Safety Instructions for the Operator
1. Electrical equipment must be installed and maintained by qualified electricians. The ap-
propriate local safety requirements and installation regulations must be observed. The
expression “qualified person” is defined in VDE 0105 and IEC 364 There is no informa-
tion contained in this operator’s manual for unqualified persons. It must be pointed out
that EU regulations prohibit the use of unqualified persons on electrical systems.
2. The details on the type plate must correspond to the electrical supply being connected
to.
3. The counter-current system may only be operated using an earth leakage circuit brea-
ker.
4. Under no circumstances must there be any conducting connection between the metal
parts of the motor and the water.
5. If the counter-current system is built into a pump pit then it must be ensured that there
is enough ventilation (for cooling the motor) and enough drainage facility for leaked wa-
ter (at least DN 40).
6. Prior to carrying out repairs to the counter-current system it must be isolated from the
electrical supply and protected from unintentional switching on.
7. Regardless of what nature they may be, repairs must only be carried out by qualified
persons and the counter-current system must be emptied first.
8. The operator must ensure that
- the operator’s manual is always available for users to read,
- instructions in the operator’s manual are being observed,
- the counter-current system is immediately stopped if abnormal electrical voltages,
temperatures, noises, vibrations, leakages or other faults should arise.
Warning! Danger of injury! / Warning! Risk of damage!
This symbol warns you of dangers through mechanical effects and also warns
of handling that could damage the product.
Warning! Mortal danger!
This sign warns you of the danger from electric shocks.
9. Persons who are likely to be endangered by radio waves (e.g. wearers of
heart pace makers) should not linger close to this counter-current swim-
ming system with radio control. In such cases it is recommended to employ
some other form of control (external or pneumatic).

4.2 Planning the pump pit
When planning a pump duct take into account:
1. Clear dimensions min. 600 x 600 x 600
2. Return connection min. 300 mm under the pool water level
3. Leakage water discharge pipe-end min. DN 40
4. Opening for cooling air min. 2x DN 125
5. Be sure to cover the pump pit if it is installed in the open air.
6. The position of the non-return air valve (L) must always be over the pool water level.
7. In case of leakage from the pump, a suitable water drainage must be provided!
8. The direct distance between the transmitter (S) and the aerial (33) must not exceed 1m!
4.3 Installation Preparations / Concrete pool
Tailor the installation kit:
Place the installation kit on the formwork board and transfer the bore holes. Bore the holes
into the pool-side formwork board (Pb). Mark out and cut holes into the outer formwork
board (P) for the suction and pressure supplies and the two hoses.
Screw the installation kit complete with the mounting protection film (C) tightly to the pool-
side formwork board (Pb).

5 Electrical Connections
5.1 Electrical Connections - general
The electrical connections to the counter-current swimming system must be carried out by
a specialised company in the electrical engineering branch approved by the local energy
provider, taking into account the technical connection requirements.
Please observe:
• The mains power connection must be a fixed connection.
• Under no circumstances must there be any conducting connection between the metal
parts of the motor and the water.
• An earth leakage circuit breaker (nominal fault current £30 mA) must be fitted to the
mains power connection.
• The mains power supply cable must be equipped with an all-pole separator with a con-
tact opening of 3 mm.
• At the marked connection terminal (at the foot of the motor or next to the terminal box)
an equalising potential with a cross-section of 10 mm² must be fitted.
• The counter-current swimming system must only be operated provided that the termi-
nal box lid is closed!
5.1.1 Direction of rotation check
In the case of 3~ motors the direction of rotation must be the same as the direction of ro-
tation arrow on the blower cover of the counter-current swimming system .
Warning! Mortal danger!
The connections must be carried out by a qualified electrician.
For this refer to the TAB of the EVS, the VBG 4(§3) and DIN VDE 1000-10/
1995-5, for example.
The relevant DIN VDE (Association of German Engineers) regulations
0100 and in the case of explosion protection 0165 must be observed.
If the installation is not carried out properly, there is a risk of getting electric
shocks!
Warning!
Compare the available power supply voltage with the details on the motor’s
factory plate and select the appropriate switching.
We recommend the use of a motor protection facility. Explosion protected mo-
tors, increased safety (Ex)–e and temperature class T3, must always be con-
nected in accordance with DIN VDE 0170/0171 via a motor protection switch.
Connect the motor in accordance with the circuit diagrams in sections5.2and
5.3.
Warning!
Check by rapidly switching on and off.
If the direction of rotation is wrong for 3~ motors, change any two phases L1,
L2 or L3 of the power supply in the motor terminal box over.
