GE 255 Valve / 400 Series Benutzerhandbuch

26

The technology upon which the Series 255 control is based is well established 
and proven in service over many years. However, should a problem or question 
arise regarding the operation of the system, the control can be very easily 
serviced. The control module can be quickly replaced or adjustments can be 
made at the installation. We recommend that you contact your local professional 
water treatment dealer for most concerns. For parts mentioned, refer to exploded 
views in the Replacement Parts section of this manual.
