If your chiller contains a horizontal pump (standard for cBoxX 30 – cBoxX 100), the pump does
not have to be vented. If your chiller contains a vertical pump (standard for cBoxX 120 – cBoxX
200) the pump has to be vented. To do this, before switching on the pump the vent plug must be
opened and left open while the unit is running until all air has completely escaped from the pump
body (see

If your chiller is equipped with an internal tank, further water circulation ensures that the residual
air in the overall system can escape into the atmosphere via the open tank.
For machines without a tank we recommend installing an automatic venting valve at the highest
point in the cold water circuit.
