How to Maintain the 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. For replacement
screens, contact your Authorized A-dec Dealer and
reference Pinnacle P/N 5512.
Follow these | To perform this
steps... function...
Turn off vacuum, or 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
disposable. Discard following
your local regulations.
CAUTION: Do not empty the
screen into your
cuspidor.
Doing so could
plug the drain.
Insert a new screen in the
3 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.
