intentionally or unintentionally.

1.6 Safety Operations

The operation and use of the device is to be done by instructed and
authorized personnel only.

Page 5

1.7 Power Supply

The equipment exclusively operates with the operating voltage indicated in the
manual.

1.8 Cable Connection

When installing the cable connections, the user needs to pay attention to
the safety regulations. Always pay attention to the connection to the
protective earth ground! Pay attention when connecting with other
devices, that those have to be of the same earth potential (same heavy
current/voltage side).

1.9 Ventilation

The equipment must be installed in so that good ventilation to the device is
ensured. Do not put any covering objects on the device, such as newspapers, books
or towels.

1.10 Water and Moisture

The device is not allowed to operate in close vicinity of electrical
conductive liquids or moist areas. It is not allowed to place any liquid
things on the device or in the nearby area of the device.

Attention: Danger of Electric Shocks!

1.11 Temperature and Heat

The operating temperature of the device is defined in the specifications. The device
must not be placed near things which produce heat such as to blowers, heaters,
furnaces or other devices.

1.12 Opening the Device

Disconnect the mains plug before opening the device!

There is a risk of electrical shock when touching the parts inside the
device. It is not permitted to make any changes in the device.

Page 6

1.13 Cleaning

Do not use any volatile solvents such as alcohol, diluents, gasoline etc.
to clean the device. Only use a dry, clean cloth.

1.14 Unusual Smell

If any unusual smoke or smell occurs, immediately switch off of the
device and remove it from the main power supply! Contact your dealer
or the manufacturer.

1.15 Fuses

The replacement of the fuses in the device is only permitted by
trained and authorized technical staff.

The change of the fuses is only allowed when the device is switched off
and is removed from the main power supply. Otherwise there is a risk of
electric shocks. The security functions and safety values are mentioned
in the manual. The guarantee for this equipment will expire in case of
using other fuses than those specified in the manual.

1.16 Repairing

The user is not allowed to perform the maintenance work by himself, except for
those specified in the manual. All maintenance and repair work must be done by
trained and authorized technical personnel.

1.17 Important notes on safety

Special Safety Instruction

Please, read and follow safety instructions carefully before assembly or using
the device!

During installation and when working with 230 V ~ mains supply the VDE
regulations must be followed. Equipment using a 230 V ~ supply may only be
installed and commissioned by a qualified tradesman. The assembly place must
allow all possible safety precautions when laying the attached cables.

Page 7

Power supply cables and data cables may not be damaged or squeezed for any
reasons. Plan the assembly place so that you can reach the mains plug easily and
unplug it from the electrical outlet in dangerous situations.
Choose the assembly place so that children cannot play or be near to the device and
at its connections without supervision.
Before opening the device disconnect it from the mains supply (unplug) otherwise
there is a serious danger of an electrical shock.
Fuses may only be replaced with standard-compliant parts with the same nominal
value.
All liability is excluded for damages which result from non-compliance of these
instructions or from an improper handling of the device. At chosen intervals in this
hand book we will give directions for safety precautions. These safety precautions
have been specially marked.

2. Description and intended use

The “SILENTIO” is an electronic water management control system. It has been
developed especially for rain water usage systems. It can be used with a wide
variety of tank systems. Tanks made from metal or steel reinforced cement may
only be used when the following conditions have been correctly followed.
Metal tanks lead to faulty readings. Helpful is to assemble the device so that the
sensor is as far as possible from the metal sides so for example, in the centre of a
cylindrical tank. The system controls offer an easy to use guide for the switch
programming.
Using an LCD display the fill measurement is shown in 1 % stages (in relation to
the height of the tank).The sensor operates with a 12 volt supply. All programmed
values such as the tank height are retained after disconnection of the power supply
or after a power-cut.

3. Description

Performance features:

– Fill level measurement readout in 1% steps and with
an additional bar type indicator
– In 1% steps freely variable choice of the switching
points for the drinking water refill

– Automatic flushing of the system (choice of intervals

in day and time are possible)
– Dialogue oriented user guidance (choice of language)
– Equipment indication using 3 additional LED
– Supervision of the measurement pick-up and the
sensor
– Error indications in plain text

Notes:

Only the control electronics in the device are protected by the fuse. Valves
and pump connections are not protected. These are protected only by the
mains supply via the mains fuse.

The yellow LED indicating “Drinking water operation” is lit as soon as the
valve switches over to the mains supply. The user is made aware that the

system now uses water from the mains supply. The red LED for “Faults
and malfunctions” is lit as soon as the system identifies a fault. The display will
then show a warning that describes the cause of the fault in plain text.

4 . Assembly:

4.1 Control system

The electric mains supply plug acts also as the ON/OFF switch.

Before opening the equipment pull the plug out from the mains
socket!

The system control is integrated as standard in the basic „SILENTIO“ device from
the company Graf. Caution: Always remove the plug from the mains socket before
opening the lower cover [7] of the system control housing!
