5400-TEOM-PCM-NH3-Dichot Pump Replacement

Purpose: This assures that the vacuum on each instrument is always good.

Required Equipment: Vacuum Pump

Reference: SOPMAN

1. When the Scheduled Maintenance ticket is initiated open a Supplies ticket for a replacement pump.
2. Once the pump has been received plug it in to make sure it wasn’t damaged in shipping.
3. On the PCM, NH3 and Dichot do not replace the pump on a run date. For any site that is running daily samples replace the pump as quickly as possible. The down time for the PCM, NH3 and Dichot has to be less that one hour or the sample isn’t valid.
4. On the TEOM and 5400 leave them running or replace the pump when regular maintenance occurs. DO NOT take them out of run mode unless other maintenance is occurring. Each of these instruments runs continuously and will take time to come back online if they are in the stop mode.
5. Remove the tubing and fittings on the old pump and install them on the new pump.
6. Plug the new pump in to the same location where the old pump was removed.
7. Turn the PCM, Dichot and NH3 on using Trigger Cals. The flows should be normal. If they are not normal for those instruments contact Plano.
8. Check the flows on the TEOM and 5400 display to make sure that they are normal.
9. If all of the flows are good then close the Scheduled Maintenance ticket with the time and date of the changeout. Include the flows on the instrument if available.
