1. POSITION
It is recommended to place the pump of the counter-current in a way that the connection between the pump and the fitting parts
is as short as possible. In any case you have to ensure that the pump is installed in a manner that the axle is in a horizontal posi-
tion. Changing the place of the pump is possible due to construction reasons. We recommend not to go beyond 5 m maximum
distance for avoiding any higher flow reduction on the suction side. While placing the installation please ensure that the pipes
in that maximum area are passed without breakes and in a horizontal way. If there are larger distances, you have to increase the
diametre of the pipes. The place of the pump has to be an area, where the ambient temperature does not exceed 40°C. Place the
pump below the water level because the pump is not self-priming. The pump and the locking parts have to be accessible any
time. Ventilation and drainage as well as floor drain have to be provided in the pump shaft.
2. INSTALLATION
The equipments is supplied as standard with all nessary fittings. The wall pack is suitable for 240 / 250 mm, alternatively
150 mm thick concrete wall and should be mounted so that the centre of the nozzle is between 200 and 250 mm below water
level and is not less than 1.5 m from the nearest side wall. After finishing of the construction and cleaning the fitting parts, you
may assemble the unit. If using a handle, it has to be mounted before. The air and pneumatic or sensor connection of the fitting
must be connected with the transitions in the wall pack. When pushing the fitting in, the hoses must not be broken. Fix the fit-
ting by using the delivered screws on the wall pack. Now, the non-return-valve in the pump shaft has to be connected to the air
hose. The non-return-valve and the pneumatic hose have to be installed above water level. PN hose / cable have to be lead above
water-level and have to be connected to the control box. Complete the piping between the pump and the wall pack in accordance
with the installation diagram and part list.
3. STARTING UP
Ensure that the pool is full of water before starting up the pump. Avoid any dry run of the pump.
1. Open both valves and turn on the installation by using the sensor / pneumatic switch.
2. Check the air injection.
3. Check the regulation of the quantity.
4. Hose and tube connections have to be checked on leakage during the working process. Due to temperature differences tighting
of the connections can get neccessary. (Check the system for leakage by throttling down as much as possible).
4. OPERATING
It is switched on and off by pressing the pneumatic or sensor switch button. The air regulator enables to mix the air into the
water jet (not valid for Tornado). The intensity of the water jet is adjusted by the quantity regulation (not valid for Tornado). The
nozzle can be adjusted in various directions.
Adjust the current speed in a way that the swimmer can swim against the full jet.
5. HIBERNATION
The pump has to be empty. Close both valves and open the screw on the housing of the pump for emptying. During down times
the circuit should never be operated without voltage (except for maintenance work) due to danger of condensation forming. Sen-
sor button during winter: For safety reasons the sensor button is to be deactivated using the switch on the control box/cabinet,
i.e. set to winter operation.
6. POSSIBLE PROBLEMS AND SOLUTIONS
6-1. Installation does not produce sufficient power:
Pump is turning in the wrong direction. Water level is too low.
Pump sucks in air. Valve is not completly open. Suction pipe leaks. Pump is clogged (with leaves for instance). If the causes can
not be identified, inform the servicing.
6-2. Pump can not be switched on:
Check cable between sensor switch and circuit as well as pin configuration of circuit and
switch summer/winter operation. Possibly reset the motor protection relay.
6-3. Relay for motor protection switches off:
Relay for motor protection is not adjusted correctly. Rated current and local
situations have to be consistent with the adjustment of the relay for motor protection.
Pump is overheated. Cool down the motor, reset motor protection relay and start it again. Phase failed - check the fuses.
6-4. Residual Current Device (RCD) switches off:
The equipment has to be checked by an electrician.
