Information on
leaks The following information on leaks does not apply to the FK 4000 Rob.
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. The leakage flow will normally sink back down to a low level
after the warm-up phase. If this is not the case then contact After-Sales Service.
Warning notices
on the device The cooling unit is fitted with safety symbols and a rating plate. The rating plate and
safety symbols must not be removed or painted over. The symbols warn against operat-
ing the equipment incorrectly, as this may result in serious injury and damage.
