2. Cleaning and Flushing
If there is a buildup of deposits or residues from the measured chemicals it
may be necessary to clean
or flush the unit. This should be done by flowing
clean, particle free water through the unit at a flow rate, pressure and
temperature within the specifications of the unit. If necessary, flow may be
reversed to assist flushing.
Under no circumstances should gas or air be flowed through the unit. This
will cause severe damage.
3. Returning Units for Repair or Recalibration
To return units for repair or recalibration please contact Dwyer Customer
Service. A Return Material Authorization (RMA) Number will then be issued
to enable the unit to be returned. Please note that no returns will be
accepted unless the RMA number is clearly indicated on the outside of all
packages.
Once the unit has been received it will be evaluated and the cost of any
repairs / recalibration determined. Once agreement has been received to
pay for all the necessary work the unit will be processed and returned. No
charges will be made for Warranty Repairs.
