Troubleshooting - parkell TurboSENSOR Gebrauchsanweisung

ilization, inspect the device in the autoclave bag
for integrity. If suspicion about the item exists,
discard it and order a replacement from Parkell
or your dealer.
• DO NOT USE DRY HEAT OR CHEMCLAVE on
the sheath or the insert.
• Detachable handpiece sheath and ultrasonic
inserts from Parkell are designed to withstand a
minimum of 250 autoclaving cycles when repro-
cessed as per the recommended autoclaving
instructions by the manufacturer.
How to Replace the Filter Disk
The water filter disk coming off of the rear hose of
the unit should be replaced when it becomes dark
or clogged with debris so that water flow is not
blocked (1-3 months). Replacement Filters are
available from Parkell (hD419 – 10 per package).
1. Close any water valves, and bleed all water lines
of residual water pressure.
2. Disconnect the scaler water supply hose from
the water supply at the quick- connect.
3. Remove the old filter disk by holding it in one
hand and loosening it by twisting it off the hose
connectors on either side. They rotate in oppo-
site directions.
4. Install the new filter disk in the same position
as the old one, and tighten the connectors in
reverse.
5. Reconnect the scaler water supply hose to the
water supply via the quick-connect and check
for leaks.
6. Note: If the filter becomes clogged and you do
not have a replacement disk, the hose connec-
tors may be locked together TEMPORARILY
without the filter disk to allow emergency opera-
tion only.
