CW 3000 Coolant

Carbide 3D - Just wondering why your webpage states one will need 20 L of coolant for the CW 3000 chiller, when the tank capacity is only 9 L?

Thanks

20L is what you should have on hand when filling the system.
The final amount of coolant needed depends on the length of coolant hoses used.

11 L extra is a bit of overkill for an approximately 6 foot run of tubing. Interested to see what Carbide 3D has to say.

Webpage says 20L, Setup manual says 9L, and the tag on the chiller says 6L (Tank).
I dumped in 2 gallons (7.8L), and it’s working fine. Coolant circulates, temp stays cool.
Spindle is cool to the touch.

Yep, what Tod says. You’ll get error messages if you fill to max cap. At least, I did.
