Collection Container
Your collection container must be changed once every twelve (12)
months or when the sediment level reaches the full line, whichever
occurs first. Check the sediment level of the collection container
weekly.
Maintenance
Line rinsing & vacuum line cleaners - cleaners should be deodorizing,
sanitizing & have a pH greater than 6 and less than or equal to 8.
Using line cleaners outside of this pH range will void the warranty.
For recommended line cleaning solution, visit our website at
www.solmetex.com.
With Dental Vacuum Systems: Follow manufacturer’s instructions.
Plan to rinse no more than 5 chairs every 10 minutes. Limit the total maximum
flow to the NXT Hg5® mini during rinsing to 1 liter per minute. Rinsing too much or
too rapidly can overfill the NXT Hg5® mini and could aect the unit’s eciency.

Service & Troubleshooting
The NXT Hg5® mini is designed to provide years of trouble-free service, with
minimal attention. In the unlikely event of system related problems, please
review the following for product support.
Q: Solids reach full line of collection container:
A: Change the collection container.
Q: Solids are above full line of collection container:
A: Change the collection container. Inspect the top chamber for solids.
Q: Top chamber has some solids:
A: System is backed up.
• Turn on vacuum
• Remove pins
• Tilt container towards outlet pipe to allow air into top chamber
• Place container back on and insert pins
NOTICE
• Refer to NXT Hg5® Collection Container Replacement & Recycle Procedure manual
at www.solmetex.com for removal and replacement of container.

Q: Top chamber is full with solids:
A: System is in bypass.
• Reduction in suction
• Solids released into waste stream and environment
• Top chamber needs to be replaced
• Top chamber needs to be recycled
Q: Little or no vacuum at the hand piece.
A: Check sediment level of collection container, if full change the
collection container.
• If the vacuum gauge reads normal but there is little or no
vacuum to the hand piece, there is probably a clog or a leak
between the hand piece and the NXT Hg5®mini.
• If the vacuum gauge reads lower than normal these are the
possible causes:
Did you just replace the collection container?
Yes: Check installation of the new collection container. If the
vacuum is low there is a possibility that the O-rings on
the collection container did not seal into the receivers.
With the vacuum running, remove the collection container,
check the O-rings and re-install per the collection
container installation procedure.
No: If you have a solids collection cup (installed by others) -
check & clean or replace element/screen if necessary.
Check operation of the vacuum pump.
- Check all flexible hose for kinks, breaks, or loose clamps.
- Check all connections for breaks or cracks.
- Listen for vacuum leaks.
Q: Water in the upper chamber (Air Water Separator)
A: Check sediment level of collection container, if full change
collection container.
• Check the pH of vacuum line cleaner: if less than or equal to 6
or greater than 8 change collection container and line cleaner.
Visit www.solmetex.com for a recommended list of cleaners.
• Call or email your dental dealer for support if the problem
cannot be solved easily.
Q: The equipment/utility room has poor lighting:
A: Bring a flashlight to check the container. Using a flashlight
from the backside of the system and shining it forward will help
determine the level of sedimentation.
