To remove the HVE or saliva ejector body, separate the body from

2the tubing by pulling it apart at the tailpiece, and removing the control valve.

Clean and rinse the valve body and control valve using a mild

4detergent, water, and the brushes that have been provide. Allow the instruments to dry completely.

Heat sterilize the valve body and control valve for six minutes using

5either of these methods: steam autoclave, or chemical vapor (275ºF [135ºC] maximum temperature).

Apply a light coat of A-dec silicone lubricant on the O-ring seals of the control valve.

6CAUTION: Use only silicone lubricant when lubricating

instrumentation O-rings. Petroleum products will cause permanent damage to the O-rings.

	Solids Collector
			The solids collector aids in preventing solids from entering the central
			vacuum system. At least twice a week, discard and replace the solids
			collector screen. This is necessary to ensure proper suction from the central
			vacuum, and to maintain proper treatment room asepsis.
			The table shows the steps for sterilizing the HVE tip.
			Step			Action
			1			Turn off vacuum, if vacuum is on, open the HVE control valve to
						facilitate removal of the solids collector cap.
						Remove the screen from the collector. The solids collector screen is
			2			disposable. Discard following your local regulations.
						CAUTION: Do not empty the screen into your cuspidor. Doing so
							could plug the drain.
			3			Insert a new screen in the solids collector and install the cap.
	Limit Switch		If activated, the support link limit switch will interrupt the base down
			motion and reverse the chair to prevent damage.
