be slippery and cause improper operation.
• To prevent damage to the pump rollers, use a gentle pushing
motion to insert the replacement irrigation pump onto the drive
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 filter case is separated, the water filter can be
removed as shown in Fig. 17. Replace filter and reassemble the filter
in the reverse order. Optional Water Filter: Order No. UPWF.
CAUTION:
Be sure to replace the water filter in the proper
direction. The side of the filter with the o-ring should be pointed
towards the control unit side. If assembled in the wrong direction
the effect of the water filter will be lost.
