Treatment of the recuperated water
The recuperated water must be filtered before entering the recycling tank. A mechanical filter must be installed
which filters off small particles (fluff, buttons, paper, etc.) of sizes 0.2 mm or smaller. The denser the mesh,
the better. There must also be a filter installed on the pressure side of the pump. It is also possible to install
an additional, chemical filter. The manufacturer advises to consult a specialist in filter systems.
Water recycling tank properties
WARNING!
IT IS PROHIBITED TO HEAT THE WATER IN THE RECYCLING TANK. THIS WOULD DISTURB THE
TEMPERATURE BALANCE OF THE WASHER AND MAKE THE REMAINING CHEMICALS IN THE
RECUPERATED WATER MORE ACTIVE, WHICH WOULD LEAD TO CORROSION OF THE ENTIRE
INSTALLATION.
The recycling tank must meet the following minimum requirements:
o
The tank must be made according to national standards.
o
Tank capacity: the capacity varies depending on multiple factors, so it must be calculated by an authorized
engineer. The factors are:
1. The number of washing steps per washer, in which the water will be recuperated.
2. The programmable amount of water that will be recuperated in a washing step (to find this amount,
please refer to the Programming manual.
3. The number of washers that will deliver water to the recycling tank.
4. The use of recuperated water per washer.
The tank must have an overflow to the sewer. Water from the sewer must not be able to flow back into
the recycling tank.
The network of pipes and hoses, the water pump and the recycling tank must be of a non-corroding
material. It must be resistant to water and chemicals used for washing.
The tank must be equipped with a system that fills the tank with clean water to a minimum required
working level, in case the water level drops below this minimum. If this requirement is not met and an
insufficient or no amount of recuperated water is fed into the washer, it will not function properly.
A pump must transport the recuperated water from the tank to the washer. The requirements for the pump
depend on the number and type of washers that are connected to the recycling system. The maximum
pump pressure is 8 bar / 116 PSI.
Water recycling tank properties
This option is not obligatory. However, it is advisable to install
a level switch. This level switch must be connected to the
microprocessor by means of a potential-free contact,
see Figure 20.
The relay contact K1 has to close when the water level
is too low. Terminal B is positioned on the left side, in the
lower part of the microprocessor. Terminal A is positioned
directly above terminal B. The microprocessor is positioned
inside the washer. If the “Check signal recycle” parameter
is set to “yes” in the configuration menu, the timer will send
a signal in case that the water level of the recycling tank is too low.
