6. Lock the connector in place with the pre-mounted screw.

Step 4. Flow regulator cap

The ring tube assembly is linked to the pump. There is a difference between the
amount of water the pump delivers at 50 Hz or 60 Hz.

Because of this it is necessary to mount the correct flow regulator cap. Standard
the 50 Hz version is mounted. The 60 Hz version is strapped near the mounting
position.

Exchange the regulator cap if necessary.

Caution
On the IntrCooll® Plus 60 Hz version, the flow regulator cap must be completely
removed / not mounted.
