Bleeding the indicator lines

During maintenance, note the following:
Water leaks from seals can result in damage to instrument compo-
nents!
Please check the instrument for leaks before carrying out the first
analysis:

To this effect switch the instrument to standby mode.

Flush the pipeline system by a short activation of key 2 (Flush).

Check all connections and seals for leaks.
To ensure that indicator is available for the initial analyses, the intake
hose and the transport hose must be filled with indicator from the
pump up to the measuring chamber.

Switch on the instrument and press key 3 (standby). The standby
function is switched on or off via a short key press. The LED above
the key flashes if the function is active.

Press key 1 (manual) for longer (approx. 2 seconds) to bleed the
lines. The dosing pump starts to run.

Let the pump run until no more bubbles escape from the dosing
needle. Then press key 1 (manual) again for approx. 2 seconds to
switch off the pump.
During operation, the pump automatically extracts the indicator.
