Commissioning
When using a peristaltic pump
a)
Venting of the peristaltic pump is not necessary. The type of pump to be used must already be taken
into account when ordering.
a)
Place the containers under the switch-over automatic in suitable collecting tubs and open them.
Ensure
that the correct chemical is used!
b)
Place the suction sets in the containers and lightly screw on the lids
c)
Plug in the switch-over automatic;
caution, the dosing pump may start!
After a power failure, suction continues at the most recently activated container.
When using a solenoid diaphragm pump
a)
Solenoid diaphragm pumps
must always be vented on the suction side
. The type of pump to be used
must already be taken into account when ordering.
b)
Place the containers under the switch-over automatic in suitable collecting tubs and open them.
Ensure
that the correct chemical is used!
c)
Place the suction sets in the containers and lightly screw on the lids
d)
Connect the suction line of the dosing pump to the outflow of the switchover valve and the return line
to the pump’s ventilator.
e)
Install the on-site suction ventilator and ventilate with a manual vacuum pump until the
suction ventilator is ¾ full.
f)
Keep the dosing pump running
g)
Check if the suction hose from the suction ventilator to the pump and the pump head are
completely vented (pump head must fill with liquid). The pump is now vented. The dosing
hose from the pump to the injection point does not need to be vented.
h)
Plug in the switch-over automatic;
caution, the dosing pump may start!
After a power failure, suction continues at the most recently activated container.
