Troubleshooting
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.
IMPORTANT: Service procedures that require the water pressure to be
removed from the system are marked with a ! after the possible cause. Refer to
Preventative Maintenance section for instructions.
