Calibrating the flow rate meter
Calibrate the flow rate meter annually by gauging. To do so, proceed as
follows:
1.
On the filter regulator, set the rinsing pressure to 2 bar.
2.
Have a measuring beaker that can hold a volume of 5 liters or more
ready.
3.
Start a contamination test in the CTU software with a flushing
volume of 5 liters.
4.
Fill the measuring beaker using the spray gun (nozzle) of the CTU
by operating the foot switch until the set volume has been
completely discharged.
5.
Read the volume on the measuring beaker. A deviation of +/- 5%
(4.75 - 5.25 liters) is within the tolerance.
The flow rate meter will need to be recalibrated if the deviation is
greater. Contact the HYDAC Service Department.
6.
The calibration by gauging is completed.
Cleaning the analysis chamber
Clean the analysis chamber every week. For cleaning, we recommend a
clean microfiber cloth.
Clean the diffuser on the filter membrane holder
Clean the filter membrane holder at weekly intervals. If necessary, clean
sooner.
1. Open the coupling (1) and remove the
diffuser (3).
2. Clean the diffuser (3) by blowing it out
with compressed air.
3. Put the diffuser into the filter membrane
holder and screw the coupling (1) finger
tight.
