Section VI Care
Cleaning
The CORE delivery unit should be cleaned as
follows:
• Wipe frequently with a damp, lint-free cloth.
• Use a neutral detergent to clean stains.
• At the end of the day, turn the master
ON/OFF valve to the OFF position and clean
instrumentation.
• Each morning, turn the master valve ON and
check the air and water systems for proper
operation using the three-way syringe.
NOTE: It is recommended that puncture-resistant
nitrile gloves be worn for the following procedures.
High-Volume Evacuator (HVE)
With the high-volume evacuator vacuum valve
in the OFF position, disconnect the valve. Using
a brush, clean the interior of the valve under a
faucet, and rinse thoroughly.
Saliva Ejector (SE)
Disconnect the saliva ejector valve from the
tubing and repeat the procedure described for the
HVE.
NOTE: After cleaning the HVE, SE and solids
collector, evacuate two cups of SlugBuster
TM
vacuum line cleaning solution (one cup each)
through the HVE and SE to sanitize the system.
Do not use abrasive cleaning agents.
CAUTION
Cleaning brushes and SlugBuster
TM
can be
ordered through DentalEZ dealers.
NOTICE
Solids Collector
To clean the solids collector located at the
instrument end of the assistant’s arm, do the
following:
1. Push the lever on the saliva ejector upward to
equalize pressure.
2. Remove the lid by lifting it straight up.
3. Grasp the stem on the basket and lift the
basket straight up.
4. Throw away and replace with new basket.
Clean Water System
Empty the bottle at the end of each day, then
before the day’s fi rst procedure, fi ll it with fresh
water.
Water Lines
To prevent contamination, maintain clean water
lines and regenerate the BioFree
TM
tubing. (Refer
to the included packet.)
Air/Water Pressure Regulator Filter
The fi lter element in the air pressure regulator is
intended to keep moisture out of the unit and the
fi lter element in the water pressure regulator is
intended to keep contaminants out of the unit. It
is recommended to replace these fi lters at least
once a year. If the fi lter element is clogged, it will
visibly look dirty, causing a pressure and fl ow
drop. In this case, the element should be replaced.
