Maintenance
The Paddle Flow Switch / Flow Meter DW-U are virtually maintenance free. In case of mal-
function first of all check the pipe system for calcification or contaminations.
For cleaning do not use sharp-edged tools and proceed with extreme caution. Damaged
instruments should be sent in for repair, as they have to be re-calibrated by the manufacturer.
Adjustments of set screws or after for instance replacement of the tension spring or
of the bellows system by the customer cause a change of the calibration.
All guarantee and warranty claims are forfeited hereby.
