Installation
1. Cable inlet for control of water reuse valve or pump
2. Water reuse inlet
2. Connect the control of your reuse valve or pump onto the con-
ductor of inlet valve I5 or I7 provided by the manufacturer,
which will disconnect the valve in question from standard
function.
IMPORTANT: The manufacturer waives all responsi-
bility for malfunction of the washing machine if a
different valve than the specified I5 or I7 is used as
the water recycle valve.
3. Fit a cable bushing into the opening, and pull the cable
through the bushing. Refer to Figure 18 .
4. Connect the coil for control of the recuperated water inlet (the
coil is not supplied with the machine), operating voltage
208-240V 50/60 Hz.
5. Secure the cable so that it cannot be pulled out of the machine
or inlet valve.
Water Reuse Specifications
Temperature range, °F [°C] 41 to 194 [5 to 90]
Maximum pressure, PSI
[bar]
Connection - outside diam-
eter, in. [mm]
The hose and the connector must be resistant to chemical sub-
stances which are used for the washing process. It is also possible
to use a hose with enhanced performance such as the rubber
EPDM hose.
The water reuse system must be fitted with a filter which must be
regularly and thoroughly cleaned (based on water quality). This
cleaning prevents prolongation of filling up times and malfunc-
tion of water valves.

Reused Water Treatment
The reused water must be filtered before entering the water reuse
tank. A mechanical filter must be installed which filters off small
particles (fluff, buttons, paper, etc.) of sizes 0.0079 in. [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 Reuse Tank Properties
It is prohibited to heat the water in the reuse tank.
This would disturb the temperature balance of the
washer and make the remaining chemicals in the re-
cuperated water more active, which would lead to
corrosion of the entire installation.
The reuse tank must meet the following minimum requirements:
•
The tank must be made according to national standards.
•
Tank capacity varies depending on multiple factors, so it must
be calculated by an authorized engineer. The factors are:
•
The number of washing steps per washer, in which the wa-
ter will be re-used.
•
The programmable amount of water that will be re-used in
a washing step (to find this amount, please refer to the
Programming Manual).
•
The number of washers that will deliver water to the re-
use tank.
•
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 reuse tank.
The network of pipes and hoses, the water pump and the reuse
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 wa-
ter 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 water re-use sys-
tem. The maximum pump pressure is 116 psi [8 bar].
It is advisable to install a level switch. This level switch must be
connected to the microprocessor by means of a potential-free
contact. Refer to Figure 19 .
