5.3 Bypass Setting<br />
Determining the bypass setting<br />
The bypass setting is identifi ed according to the application and the carbonate hardness identifi ed<br />
on the basis of the bypass and capacity table (Chapter 7). The bypass is then set on the bypass<br />
screw 19 as follows:<br />
Turn the bypass screw 19 until the desired bypass (0–3) agrees with the marking.<br />
! Caution: Use 6 mm or 7/32" Allen key.<br />
