(4) Pressure build-up/filling the interstitial space:
Press and hold the "Filling" button for about 5 seconds until the
yellow signal lamp is blinking. The solenoid valve will open to
quickly fill the interstitial space. When the operating pressure has
been reached, the filling process is turned off and the yellow sig-
nal lamp will go out.
With very large interstitial spaces it may be necessary to switch
bottles (see section 5.3 in conjunction with sections 5.4 and 6.1)
Note: If no pressure build-up is achieved with the pressure gas
bottle connected, the leak must be located and corrected (check
the settings for the pressure reducer as well, if necessary). CAU-
TION: Display on the leak detector (display) begins with a pres-
sure from 150 mbar.
(5) It may be necessary to press the "Filling" button repeatedly to
achieve complete filling of the interstitial space.
(6) Check all connections for leaks with a foaming agent.
(7) Perform a functional check according to section 7.3.
6.3
Changing the Operating Mode
(1) Switch positions 1-9 are designed to select the pressure level,
switch position 10 is designed to select the operating mode.
(2) The operating mode "I" or "C" can be set or changed at the con-
struction site by changing the position of switch number 10 on the
switchboard.
(3) Switch positions for the pressure levels (switches 1 to 9) are
shown for each pressure level in section 3.3.
(4) If the switch positions 1-9 are changed at the construction site, it
must be assured that the set pressure level does not exceed the
set pressure for the overpressure valve.
