11.3 Changing the LCS Water Filter
The water filter (Part No. 01-110731S) should be changed every 90 days, or as
required. The frequency of filter change will depend on the number of cycles run
with handpieces and the amount of debris in the wash chamber water.
CAUTION: The water filter housing may be hot if a cycle has recently been run.
When the water filter
has to be replaced the
unit will display the
following screen after
selecting the cycle:
By pressing OK the unit
moves to the “Start” screen.
Using a Phillips screwdriver, open the
panel on the right hand side of the
machine. Remove the air filter.
Pull the water filter housing out of the
unit, taking care not to detach or
damage the two water tubes.
Disconnect the quick connect.
Unscrew the cap from
the base and rinse with
water to remove an
debris. Unscrew the old
filter from the base and
discard. Remove any
visible debris.
Insert a new filter and
hand tighten. Replace the
cap and re-insert the filter
housing, taking care not to
pinch the water tubing.
Replace the air filter.
Replace the panel and
screws.
