Inserting the indicator bottle
Open the housing cover to access the housing.
Remove the cap from the indicator bottle.
The supplied plastic bag contains the blue screw cap with a hole
and the respective insert for the indicator bottle.
Caution!
There are two inserts. One is for the 100 ml indicator bot-
tle and the other one is for the 500 ml indicator bottle. The length
of the suction tube indicates which insert is for which bottle. Select
the insert that matches your indicator bottle. When inserted, the
suction tube should almost reach the bottom of the indicator bottle.
Place the insert
into the indicator bottle.
Screw the blue screw cap with hole
hand-tight onto the indica-
tor bottle.
Place the indicator bottle
next to the water inlet in the housing.
Push the intake hose
hand-tight onto the hose connector of the
insert.
Bleeding the indicator lines
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.
Opening the water inlet
Slowly open the manual stop valve in the water line to open the
water inlet.
