Setting the pressure switch (41)
The installed pressure switch (41) records the booster pump's (39) effective pressure. In the
event of air Inlet or a pressure drop in the water supply, the GRANUDOS dosing device
switches off when the value falls below the switching pressure. In addition to the electric
locking, this ensures that:
The dosing is turned off if the booster pump does not convey enough water.
The booster pump is not exposed to the risk of cavitation.
To set the switching point, the dosing device must operate in automatic mode. Remove the
lid from the pressure switch, turn the adjustment knob 0.25bar to the right and wait for 6
seconds. If the dosing device continues to run, repeat the process until the dosing device
stops and the fault indication
“Pressure too low” appears. The GRANUDOS dosing
device stops. Now turn the adjustment know 0.25bar to the left and acknowledge the alarm
message. The dosing device will start up again. Now, the dosing device will throw a fault at a
pressure drop of 0.25bar.
A switching point of 1.5barg is factory-set.

Setting the water level in the flushing tank
The water lever in the flushing tank can be changed by screwing the float at the float control
valve (45) in or out. A higher level is achieved by unscrewing the float, a lower level by
screwing the float in. One revolution corresponds to approx. 1cm. Adjust the float in the
flushing tank so that the water level corresponds approximately with the centre of the
flushing tank.
