1.1 Description of the function

Apart from the mechanical water treatment

(filter / pool hydraulics), it is vital to control hy-

giene parameters such as pH value and disin-

fectant levels. The classical method of manual

measurement and correction is time-consuming

and awkward. For the dosing unit to perform its

task, there are some basic conditions which have

to be met. They are described in these instruc-

tions. You can use the control unit only for pri-

vate swimming pools with a maximum water

volume of 65 m

1.2 pH-value and active oxygen

The pH value is a key indicator of whether the

water is acid, neutral or basic. A value of 7.2 has

been found to be optimal for people and for the

technology. Moreover, the disinfectants have

their maximum effect at 7.2.

Disinfection with active oxygen is especially ef-

fective in pools not very polluted (dirt, frequen-

cy of bathers, etc). Your pool professional must

install a bigger-sized filtration equipment, as this

alternative product has a poorer effect in com-

parison with chlorine. Water temperature should

not exceed of 28° Centigrade. With a higher

temperature, algae, viruses and bacteria can eas-

ily proliferate. Shall your hygiene parameters in

the pool not meet your demands (despite of a

regular dosing of active oxygen), we recommend

a hyperchlorination to disinfect the pool again.

Optimal pool hydraulics are just as important.

This is because no disinfectants can enter areas

where the water cannot be circulated. Algae

growth mainly starts in the corners and on the

bottom of the pool. Hence depending on the

amount of growth, walls and bottom have to be

cleaned mechanically occasionally. Dirt is col-

lected inside the pre-filters (skimmer / filter

pump) too, and must be removed regularly.

For the dosing unit to work optimally, the filter

unit must be switched on at least 10 hours per

day and backwash must be done at regular inter-

vals (1x per week). Fresh water input (automatic

or manual) occurs only outside the running

times of the filter, so that the untreated water

cannot influence the measurements taken by the

dosing technology.

1.3 Installation

The dosing unit must be installed in a dry room

with good ventilation. To avoid damage if the

system breaks down, there must be a drain of

sufficient size. The control unit is fixed to the

wall with the fixing screws included in the scope

of delivery.

Please ensure that the suction pipe of the dosing
pump is as short as possible. Hence the safety
cans are placed directly under the device. The
suction lances must be screwed in the chemical

tanks and connected to the control unit using
the plug. The injection valves for pH and disin-
fection are installed as shown on the installation
diagram. The test water pipe is to be connected
to the flow cell as shown in the installation dia-
gram.

The mains cable and the temperature sensor

have already been connected inside the con-

trol unit. The maximum permissible voltage

is 230 V. The mains socket must be sited as

close as possible to the device and inter-

locked with the filter pump, that is, the elec-

tric mains socket is allowed to be live only

when the filter pump is running. The swim-

ming pool installation is to be equipped

with a separate FI switch. Please observe

the official standards for wiring regulations

(i.e. German DIN VDE 0100) as well as lo-
