The green lighted rocker switch should always remain in the ON position and the variable speed
knob adjusted to the highest position for maximum suction. The variable speed knob can be
adjusted to lower suction as per user preference.

Recommended Cleaning Instructions
(Does not supersede ADA, CDC or OSAP disinfection
guidelines):
After each use
, the hood opening, and rigid flexible hose should be cleaned.
1.
Make sure the unit is turned off and the hose is fully compressed and in a standing upright
position.
2.
Using approved disinfection wipes, wipe down the inside and outside of the hood opening
thoroughly. Using a second wipe, wipe down the outside of the hose thoroughly.
3.
Turn the unit on with variable speed knob turned to the lowest setting to reduce CFM. Spray
the inside of the hood opening for 5 seconds with an aerosol disinfection agent that is greater
than 70% alcohol. The suction will draw down the disinfecting spray into the hood opening to
cover the inside of the hood opening and rigid flexible hose from top to bottom. Shut the unit
off and reset the variable speed knob to its appropriate setting.
4.
Any additional required cleaning in accordance with CDC, ADA or OSAP guidelines.
