5 .6 Connecting the cooling water control (ECO-versions only)
The ECO -versions of the Scrubber are equipped with a cooling water control ensuring the flow of the
cooling water is switched on every time the K-415 is switched on by the digestion instrument and is
turned off the same time, the digester is turned off. (Assumed the external cooling water source is
always turned on).
The cooling water control a can be found on the rear side of the instrument with cooling water inlet b
at the bottom and the cooling water outlet on top. The cooling water inlet can be horizontally swivelled
around in a range of 180 degrees. This makes it possible to orient the inlet towards the available
cooling water supply.
To swivel the cooling water inlet, proceed as follows:
• Loosen the nut on the bottom of the inlet c, using the matching end of the provided Multi-tool d.
• Swivel the inlet b to the appropriate position.
• Tighten the nut c with the Multi-tool d.
NOTE
After swiveling the cooling water inlet to the preferred position make sure the fixing nut c is tight and
check all connections and tubing of the cooling water control for tightness.
