All pumps are self-priming, no overpressure is necessary at the tanks.
5 .3 .1 Cooling water connection
The water pressure should be at a maximum of 4 bar. The built in valve reduces the water flow to 1.2
liters per minute.
The flanged screw coupling for the water connection has a standard screw thread of G ¾”.
5 .3 .2 Drainage of cooling water
Place the drain hose for the cooling water directly into the drain. For this purpose, shorten the silicone
hose to the optimal length. The drain hose should not show any kinks, sharp bends and/or siphoning
effect. Prevent flooding inside and outside the instrument by securing the drain hose.
