8.5 Deaerating the pump manually
Conditions for deaerating:
• The internal batch tank must contain chlorine dioxide solution.
• The dosing pump must be operated in "manually dosing"
mode.
• The dosing pump is running:
1. To deaerate the pump, turn the green deaeration knob
clockwise as far as it will go. Observe the direction of the
arrow on the protective cap.
2. As long as the deaeration knob is turned, the dosing medium
can flow through the relief line to the tank.
3. When released, the deaeration knob returns to its original
position automatically.
