Firmware up-

are not described in these operating instructions, or vice versa. Certain illustrations may
also differ slightly from the actual controls on your device, but these controls function in
exactly the same way.
Information on
leaks The following information on leaks does not apply to the CU 800i Pro, CU 1200i Pro/MC,
or CU 1400i Pro/MC.
The shaft sealing surfaces inside the coolant pump are lubricated by the coolant, mean-
ing that a certain leakage flow should always be expected. A low leakage flow is permit-
ted.
The coolant pump requires a certain warm-up time after being started for the first time or
upon restarting after a long period of downtime. An increased leakage flow can occur
during this warm-up phase. After the run-in period, the leakage flow normally drops again
to a low level. If this is not the case, contact the after-sales service.
