COVID 19 | Restarting Your Equipment After An Extended Shutdown 

As you ready your office following COVID-19 restrictions, here is a checklist to prepare your equipment for patient care. We encourage you to do start-up procedures a few days before seeing patients so any issues that pop up can be resolved. If at any time you need assistance, email us at

Turn on vacuum pump and compressor.  Check operation.

  • Ensure compressor builds up to pressure (120 – 125 psi).

  • Before turning on wet ring vacuum pump:

    • Ensure water source is ON.

    • Check gauge for proper operation.

    • Check for any water leaks.



  • Turn on unit or system.

  • Inspect for any degraded apparatus or leaks.




  • Fill autoclave reservoir with distilled water.

  • Run unwrapped test cycle.


  • Fill and test.


  • Confirm main water supply ON.

  • Reinstall soap dispenser.

  • Run cycle to test.


Operatories – Two Steps

1. Shock Waterlines Upon Return – per manufacturer’s guidelines

Before resuming care using your dental unit, thoroughly shock the DUWL regardless of the maintenance product utilized.


If using straws: never shock through a straw unless using Sterisil Straw with Citrisil™ Shock. Otherwise, remove the straw and utilize a "dummy straw" or uptake tube to shock.


If you need a free dummy straw, order one from or send email to


2. Test Your Dental Unit Waterlines After Shocking

Once DUWL shocked, test dental unit water quality to ensure CDC guidelines are met.  Reach recommends the ProEdge™ QuickPass™ test for a simple in-office test.


Computer Systems

  • Verify backups have been occurring.

  • Power on each machine to ensure everything is booting up properly and communicating.

  • Verify antivirus/security software is up-to-date.

  • Allow any updates to occur (may require extra time and multiple restarts).


Milling machines

  • Fill water tanks to proper level with distilled water and lubricant.

  • Run mill in pump mode to allow the water system to prime and cycle.

  • Ensure proper communication to the acquisition units.  Perform calibration if necessary, or if the annual maintenance period has expired.  Verify condition of burs.

  • Perform a test mill if applicable.
