Cleaning / Maintenance - Renfert SILENT TC Kurzanleitung

For devices with standby mode, these should be switched on approx. 5 minutes before setting to
avoid incorrect measurements.
If there is an error with the switch-on function, the display "C" will blink and an acoustic signal is
emitted twice. Set the changes again. If necessary, select a higher speed for handpieces.
For detailed information on "Troubleshooting", see the instructions for use which you can down-
load from our website at www.renfert.com/p915.

In order to prevent the suction from being switched on / off too often in the case of short interrup-
tions (for example when working with the handpiece), a higher time value can be selected.

Empty Dust Drawer
After reaching a set time interval, a request appears to empty the dust drawer:
♦ An acoustic signal sounds 3 x.
♦ Display dust drawer (26) lights up.
♦ The display (24) shows a container filling up.
Before removing the dust drawer, a filter cleaning function should be performed:
⇒ Press Enter key (27) for 2 seconds.
♦ The filter is cleaned (duration approx. 8 sec).
♦ The counter for recording the time interval is reset.
After the filter cleaning has finished:
⇒ Unlock the dust drawer with the clamp fastener (4a).
⇒ Pull the dust drawer (4) forward and empty.
⇒ Replace the dust drawer again until it locks into place.
⇒ Close the clamp fastener (4a).
If the dust drawer has been emptied without prior filter cleaning, the counter must be reset separately to
record the time interval.
⇒ Press the Enter key (27) (counter for recording the time interval is reset).
♦ Acoustic signal acknowledges the information.
♦ Dust drawer display (26) is deleted.
If the dust drawer is not emptied, the dust drawer (26) display will still light up. After switching the
device off and on again, a 3 x acoustic signal is used to indicate the emptying of the dust drawer.
To set the time interval, see Fig. D at the beginning of this document, or refer to the Instructions for Use
on the Internet.
