Adjustment of suction capacity
The further procedure is only possible when the device is turned on.
a)
Switch on the device at the main switch.
The booster pump starts, unless the pressure switch (31) or the level switch min (48) respond.
b)
The hole washer in the pipe union (41) behind the injector (40) adjusts the injector’s suction
performance to the pressure conditions. If the water level in the flushing tub (39) drops during
commissioning, a hole washer with a smaller drill hole must be inserted in the pipe union.
c)
If the water level rises, or if the flow switch’s (42) switch body is not clearly pushed upwards,
a hole washer with a larger drill hole is required, or the hole washer must be removed entirely.
A hole washer with 6 mm is installed ex works; hole washers with 5.5 mm and 7 mm are available in
the enclosed spare parts bag.
