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.
Page 9
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!

Figure 3: Sensor technology Now the sensor measurement pick-up [28] (cover removed) should be installed on the tank wall (preferably in the man hole shaft of the Graf synthetic tank). The location of the mounted sensor pick-up should be between 10 and 15 cm above the overflow [25]. The enclosed screws should be used to secure the device.

Page 22
3. Optional refill If the fill level in the main tank sinks below a specified level, then a second tank is employed to back up and re fill the main tank. The pump used in this process must also be equipped with a mechanism to prevent it from running dry.
