.
MAINTENANCE
The DW-D is essentially maintenance-free. However, depending on the degree of pollution in
the medium, it is recommended that the sensor system be inspected and cleaned as
necessary from time to time.
Under no circumstances attempt to remove the pendulum from the unit as this will destroy the
calibration. Clean the pendulum system before re-installing into the pipe.
IMPORTANT! If the DW-D must be separated from the tee loosen nut (A) and cant the
unit a little opposed to direction of flow. Then lift the DW-D with pendulum rectangular
out of the tee. Please perform all disassembly/reassembly operations with great care.
Avoid damage! Especially to the pendulum system.
