Setting the water flow in the dissolving unit
The further proceedings are only possible when the device is turned on.
Turn the device on, using the main switch on the left side of the control unit. The booster
pump starts up. When the device is turned on, the pump is in permanent operation, except
when the pressure switch (41) or the level switch min (38) respond.
The washer in the screw connection (36) behind the injector (42) adjusts the injector’s
suction performance to the pressure conditions. If the water level in the flushing tank (46)
drops during commissioning, an orifice with a smaller bore must be inserted in the screw
connection.
If the water level rises, or if the flow switch's (47) switching body is not clearly pushed
upward, an orifice with a larger bore is required, or the orifice must be removed entirely.
An orifice with 6mm is installed by the factory; orifices with 5.5mm and 7mm are available
in the enclosed spare parts bag.
