PlasmaQuant MS product family Maintenance and care
115
Cooling water additive (10 g biocide + 10 g corrosion inhibitor)
Distilled / demineralized water (σ < 10 µS/cm)
Beaker (V = 1 L) for mixing the cooling water additive
Short tubing, olive, bucket to catch the drained coolant
The water cooler is drained as far as the marking MIN.
The water cooler is connected to the PlasmaQuant MS.
Optimum conductivity range 100-120 µS/cm
Target conductivity range 75-150 µS/cm
1. Dissolve both bottles of the biocide and corrosion inhibitor in 1 L of distilled /
demineralized water.
2. Pour about 300 mL of the prepared solution into the water tank:
Open the door at the top of the water cooler.
Unscrew the sealing cap from the filling opening of the tank and insert a
funnel.
Pour the solution into the tank.
3. Fill the tank with distilled / demineralized water until the MAX level mark is
reached.
4. Switch on the water cooler. Switch on the PlasmaQuant MS: Start the vacuum
system and ignite the plasma.
5. Allow the system to run for 10 minutes to rinse the cooling water lines.
6. Shut down the PlasmaQuant MS and switch off the water cooler.
7. Drain the coolant:
Attach the short tubing to the drain tap (marked with "Drain"). Hold the tubing
in the bucket.
Open the tap and drain the tank as far as the marking MIN.
For models without drain tap:
At the water cooler remove the inlet connection with the marking "Return". With
the tubing olive connect the short tubing to the connection.
The valve at the inlet connection closes automatically if no olive is connected.
Hold the tubing in the bucket to catch the drained coolant.
Drain the tank as far as the marking MIN.
Reconnect the tubing to the inlet connection of the water cooler.
8. Rinse the system once more. Therefore, repeat steps 2-7.
9. Fill the rinsed water tank with cooling water:
Pour about 300 mL of the prepared solution into the tank.
Fill the tank with distilled / demineralized water until the MAX level mark is
reached.
Remove the funnel. Seal the filling opening with the screw cap. Close the door at
the top of the water cooler.
