00:06 WHY YOU NEED TO CLEAN YOUR PT-500
While the PT-500 is designed for reliability in wastewater and other dirty or turbulent liquids, extended exposure to these environments can lead to residue accumulation.

Residue accumulation on the diaphragm of your sensor can cause inaccurate readings or even damage to the diaphragm. Since the diaphragm can easily be damaged, even a well-intentioned attempt to clean the sensor could result in damage.

HOW TO CLEAN YOUR PT-500

0:41 WASH THE SENSOR BODY
Start by washing the main body of the sensor and cable. This can be done by spraying the sensor with pressurized water or washing it in a sink. Be sure that water is not sprayed directly at the diaphragm, as this can damage it.

00:55 CLEAN THE CABLE
Remove any debris and residue from the sensor and cable using a soft scrubbing device and mild soap if desired. Do not spray or scrub the diaphragm surface.

01:08 FOR WASTEWATER USE
If the sensor has been in use in an unsanitary environment, such as a sewer or wastewater tank, be sure to use a sterilizing cleaner.

01:17 PROTECT THE DIAPHRAGM
Remember to keep any pressurized water and scrubbing devices away from the diaphragm.

01:22 REMOVING RESIDUE FROM THE DIAPHRAGM
Once the body of the sensor has been cleaned, it is time to remove the residue accumulation from the diaphragm.

First, choose a cleaning agent suitable for removing the residue accumulated on the diaphragm. CLR is great for the removal of mineral residue such as hard water stains or sediment deposits, as well as most organic waste, such as wastewater residue or sewage.

The idea is to use the chemical properties of the cleaner to break down and remove residue to prevent the need for physical scrubbing or scraping.

Using a container sized to accommodate the sensor, place the diaphragm end in the container and fill to a depth that the entire fitting is submerged in the cleaner. Leave the sensor soaking in the cleaner for 15 minutes then agitate to remove loose residue and check the diaphragm surface.

Repeat, this process until all debris has been washed away from the diaphragm.

02:21 DO NOT TOUCH, SCRUB, SCRAPE, OR SPRAY DIAPHRAGM
Again, do not touch, scrub, scrape, or spray the diaphragm surface.

Once all residue accumulation has been removed from the diaphragm submerse the sensor in clean water and agitate to remove the cleaner.

02:37 YOUR PT-500 IS NOW CLEAN
Your PT-500 is now clean and ready to be returned to use.
