Troubleshooting

If valve function is adversely affected by accumulations of biological matter,
it may be possible to dislodge the material and restore proper function
through one of the following methods:
• Flushing and/or pumping the valve (only for those valves
without SIPHONGUARD)
• Multiple programming attempts
Multiple programming attempts using a current CODMAN programmer
(catalog no. 82-3190, 82-3190R, 82-3192 or 82-3192R) should be
attempted if there is difficulty in programming or changing the setting of the
valve. For additional information related to programming the valve, please
refer to the manual packaged with your CODMAN Programmer.
If these remedial steps fail to rectify the problem, replace the valve.
