Setting the pressure switch
The installed pressure switch (31) records the booster pump’s (36) effective pressure. In the event of
air intake or a pressure drop in the water supply, the 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 transport enough water.
The booster pump does not run dry.
To set the switching point, set to automatic operation mode.
Remove the cover from the pressure switch, turn the adjustment knob clockwise by 0.25 bar and wait
for 6 seconds.
If the GRANUDOS continues to run, repeat the process until the GRANUDOS stops and the “Pressure
too low” fault indication is displayed. The GRANUDOS stops. Now turn the adjustment knob 0.25 bar
counter-clockwise and acknowledge the alarm message. The GRANUDOS starts up again. The GRANU-
DOS will now throw a fault at a pressure drop of 0.25 bar.
A switching point of 1.5 bar is preset ex works.

Setting the water level in the flushing tub
The water level in the flushing tub can be changed by screwing the float at the floating valve (47) 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 water height. Adjust the float in the flushing tub so that the
water level corresponds approximately with the centre of the flushing tub.
TIP!
This concludes the commissioning of the dosing unit.
