2. Open the cap of the irrigation bottle, remove any remaining solution and ll the bottle with distilled water.
3. Close the cap rmly and replace the bottle on the control unit. (Make sure the air hole is clean and free
from debris). Insert the bottle into the irrigation connector opening; push down until it clicks.
4. Operate the unit for approximately 30 seconds with irrigation bottle water ow at maximum setting.
WATER LINE MAINTENANCE
Local, regional and federal authorities establish safe potable water quality level guidelines for human use. In
Europe the maximum accepted level of colony forming units of bacteria (cfu’s) for potable water used in
DUWLs is no more than 100 cfu/ml at a temperature of 22°C (20 cfu/ml at a temperature of 36°C). In the
U.S., the Centers for Disease Control established a 500 cfu/ml level, while the American Dental Association
sets a maximum level of 200 cfu/ml. Follow regulatory recommendations in your region regarding ushing
dental unit water lines.

shaft. Do not twist.
• Run the replaced irrigation pump about 10 seconds on highest
water volume setting before operation to adopt irrigation tube
to new pump.
CHANGING WATER FILTER
Close the water valve of the dental unit to which the Symmetry IQ
4000 control unit is connected. Mount two (5X8) spanner wrenches
as shown in Fig. 25 and turn in the directions shown.This motion may
cause the water tube to become twisted. If this occurs, relieve the
twist by turning the tube at the end on the control unit so the side is
free to turn.
When the water lter case is separated, the water lter can be
removed as shown in Fig. 17. Replace lter and reassemble the lter
in the reverse order. Optional Water Filter: Order No. UPWF.

EU REGULATORY INFORMATION
When drawing water directly from a dental chair or other water supply system within a dental practice for
the Symmetry IQ 4000, a system or device must be installed to ensure that no contaminated water can
ow or be sucked back into the drinking water supply. When installing such a system please observe that the
requirements of the EN1717 Regulations are adhered to.
HELPFUL INFORMATION
The use of higher than recommended power setting may cause excessive wear or tip breakage.
Always remember to properly tighten the tip to handpiece using the Guardian wrench.
Scaling efciency can diminish signicantly with worn tips. Inferior performance and poor water delivery can
result from worn, damaged, bent or altered tips. For optimal scaling efciency, we recommend checking tips
regularly for signs of wear.
CHECKING SYMMETRY TIPS FOR WEAR:
1. Locate the diagram of the tip to be measured on the
Symmetry Wear Guide (HF-469).
2. Rotate the tip until it is at against the card.
3. Evaluate tip condition, comparing length to red/blue lines.
1mm loss can result in
25% efficiency loss
2mm loss can result in
50% efficiency loss
