How to Replace the Filter Disk

The water filter disk coming off 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 (package of 10
filters— hD419).
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 opposite 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. Engage PURGE mode to allow water to flow out the end of
the handpiece into a sink.
Note: If the filter becomes clogged and you do not have a
replacement disk, the hose connectors may be locked together
TEMPORARILY without the filter disk to allow emergency operation
only. Water Filter is a single use part. Once replaced, the old water
filter should be properly disposed in trash and must not be reused.

Troubleshooting

Unit does not operate
("power on" indicator does not light)
• Main ON/OFF switch is not set to on; Check that switch on
rear panel is in up position.
• Power Adapter cable is disconnected from wall outlet or
scaler. Reconnect properly.
• Wall outlet is not powered. Use different wall outlet.
• Unit fuse has failed. Contact Parkell.
Insert does not vibrate properly
• Faulty, damaged, or worn insert. Replace.
• Insert not correctly seated in handpiece. Reinsert properly.
• Use a new Parkell® brand insert.
• Power control not correctly adjusted. Readjust.
Excess heat at handle or tip of insert
• Faulty, damaged, or worn insert. Replace.
• Too little water flow. Insert may be blocked. Inspect & clear
blockage or replace insert.
• Power too high for water. Increase water flow.
• Excessive hand pressure applied. Correct technique.

No water spray when foot pedal is depressed
• Water line blocked or kinked. Correct.
• Water passage in the scaling insert clogged. Inspect and
clear blockage or replace insert.
• Water filter clogged. Replace.
• No water supply connected. Correct.
Insert does not go into handpiece
• Insert stack is bent. Straighten plates carefully by hand and
reinsert.
• O-ring is too tight. Lubricate O-ring with water and use
twisting motion to seat insert.
• Detachable 30K Handpiece (hD722) can only accept 30K
insert. Make sure that it is not a 25KHz insert, as it will not
fit inside the handpiece.
Insert falls out of handpiece or water leaks from front
of handpiece
• O-ring damaged or worn. Replace O-ring on the insert.
Water leaks at base of handpiece
• Orange O-ring at end of handpiece missing or damaged.
Insert comes out of handpiece when pedal is depressed
• Water pressure is too high. Adjust water pressure to 15-35
psi at dental unit connection or in floor junction box or
replace insert O-ring.
Purge Mode does not activate
• Make sure to disconnect detachable handpiece from the cable.
• Activate the unit by pressing the foot pedal. Purge LED
should start blinking.
• Contact Parkell for support if problem is not resolved.
Scaling Power has reduced to minimum automatically
• Foot switch remained pressed continuously for more than 3
minutes. To avoid any accidental damage, scaling power was
reduced to minimum after 3 minutes of continuous foot switch
press. Scaling and water flow will be disabled completely after
10 minutes of continuous usage. This is normal.
• Release foot switch and press again. Contact Parkell for
additional assistance.
• Upon activation, TurboSensor+ detects if handpiece is
detached from the cable / if there is no insert connected into
the handpiece. TurboSensor+ then disables output oscillator
reducing power consumption and heat generation.
• To improve safety, Turbo+ disables water flow after 2 minutes
of pre-determined purge duration. In the event of accidental
– unattended continuous foot switch activation, this feature
prevents water damage in the dental office and prevents
handpiece overheating, if external valve is closed.
• TurboSensor+ detects insert stall and instantly recovers upon
release of the tip preventing damage to the teeth / gum line /
other anatomical structure during a clinical procedure by
momentarily shutting down the oscillator and reducing power
output significantly.
• Always Awake. Without a "Sleep" mode, TurboSensor+ always
remains ready for activation while powered on. Position the
foot pedal to avoid accidental activation.
