Replacing the braided hose for outlet
1.
Switch off the master switch of the NTI 1000.
Risk of injury due to pressure in the hoses
High pressure in the hoses might cause the
hoses to fly apart and cause injury.
¶
Ensure that the pressure of the nitrogen
tank is less than 2 bar before replace-
ment.
i
To reduce the pressure, open the safety valve of the
nitrogen tank till the pressure drops to atmospheric
pressure.
!
Ensure that you tighten the safety valve of the tank
after releasing the pressure. If the safety valve is
not tightened, the nitrogen filled into the tank will
escape and the operating pressure of 10 bar will not
be achieved.
2.
Disconnect the braided hose from the quick
coupler at the digital port for inflation/deflation
(Fig. 2, Pos. 8, 10).
