6

Load pressure accumulator chamber to the prescribed pressure by using the pressure pump (4)

 If pressure is too high, it can be corrected by pressing the depressurizing button (3) on the pump  (4).

 For technical reasons that can not be avoided, adjust the pressure approx. 0.2 bar higher than prescribed, because pressure drops in this order when the pump supply hose  (4) is detached at the supply connection (2).
