Pump Maintenance
In normal use, the pump should be taken apart, cleaned and re-lubricated after 100 to 200 samples have been drawn.
To disassemble:
Unscrew the cylinder and cover
Slowly pull the pump and pressure-relief valve from the front and of the pump
Clean all the bearing surfaces carefully using non-abrasive wipers and a good degreasing solvent such as
trichloroethylene or perchloroethylene.
Lubricate all surfaces that make metal-to-metal contact with the special silicone grease supplied with the pump kit.
Reassemble the pump carefully, making sure that abrasive particles that could score the walls do not get inside the pump.
Verification of Ozone Output
Verify, and if necessary, adjust flow rate to 0.5 lpm. After the generator has been on for 60 minutes or longer, open
the valves on the gas bag. Next flatten and roll it up to empty as much of the air from the bag as possible.
Close one valve and attach the bag to the output port on the generator.
Allow the bag to fill partially with ozone, remove it from the generator and empty the bag again, as described above.
Reattach the bag to the generator and partially fill. Open the second valve on the bag, insert the end of the detector
tube into the valve on the bag and draw a sample.

When sampling cycle is complete, check tube for Ozone concentration.
If within 10% of desired output, generator is working properly.
If not within 10% of desired output, see Ozone Output Adjustment section for Ozone Generator.
