Checking the Concentration Setting

Required auxiliaries:
In the following example which shows how to determine the nominal concentration, the
quantity settings given in millimeters refer to a tapped water quantity of exactly 8 liters.
Formulas for setting the concentration:
Explanantion:
K = Concentration (%)
VD = Volume of disinfectant (ml)
VW = Volume of water (ml)
Example:
Disinfectant quantity to be set according to the above formula:
To check the concentration setting, proceed as follows:
 Unscrew the flow control unit from the mixing chamber and seal the mixing chamber
opening with the supplied sealing plug.
 Insert the flow control unit into the provided measuring jar and place a bucket below the
swivel drain outlet.
 Press the ON/OFF (I/0) switch and tap approx. 2-3 liters of water.
 Empty the bucket and the measuring jar.
 Insert the flow control unit back into the measuring jar and place the bucket below the
swivel drain outlet again.
 Start the unit by pressing the ON/OFF (I/0) switch.
 Tap exactly 8 liters of water. Switch off the unit (press the ON/OFF (I/0) switch).
 Read the disinfectant quantity collected in the measuring jar.
 Calculate the concentration according to the above formula. If it deviates from the
desired concentration (plus buffer), adjust the setting as described
in chapter
 Remove sealing plug from mixing chamber opening and screw flow control device in
again.

Checking the Safety Equipment

A check of the safety equipment obligatory includes the following test procedures:
 functional test of the level suction pipe
 functional test of the flow control device
6.2.3

Functional Check of the Level Suction Pipe

For the functional test of the suction pipe "empty" signal device, proceed as follows:
 Pull suction pipe out of product supply container.
 After approx. 3 seconds, unit should change to fault mode (red fault indicator flashes).

Bucket with a minimum capacity of 10 l to collect the water
Measuring jars to collect the disinfectant:
up to 100 ml for concentrations of 1 % max.
up to 300 ml for concentrations of 1 % to 3 %
Desired concentration = 0.5 %, plus 10 % buffer
