Today, we will be reviewing the installation of a LibertyBOSS using the Wet Upgrade Kit from M.A.R.S Bio-Med. The M.A.R.S Upgrade Kit supplies everything needed for a Dental Practice to upgrade their office to a LibertyBOSS.


The M.A.R.S Upgrade Kits were created to provide everyone access to the NO maintenance, NO Inspection, NO filter, M.A.R.S LibertyBOSS. Regardless if you are DIY Doctor, don’t have a Service Technician that is a M.A.R.S Certified Amalgam Separator Specialist, or a service company looking to help your client save on their amalgam separator costs. With the Upgrade Kits, anyone can install a LibertyBOSS with minimal tools, experience, or aptitude.

  • 1 ¼” inlet hose with quick connects and rubber coupler
  • 1” outlet hose with quick connects and ¾” threads
  • ¾” to 1” bushing
  • 1 ½” street elbow
  • LibertyBOSS
  • A case of PowerLINZ Evacuation Line Cleaner
  • Two 1 ½” close out plugs

The tools required;

  • Hacksaw
  • 5/16 nut driver
  • Duct tape
  • Respirator to protect yourself from mercury gases is suggested


Need for the Upgrade

We are recording this installation while upgrading an eight-chair practice to a LibertyBOSS. Their old SolmeteX Hg5 was neglected, only changed every 12 months. A practice this size would require a filter change, on average, every 3-4 months. In addition, the upper chamber and the lower chamber are separating, creating a toxic leak in the mechanical room.


Preparing for the Upgrade

The first step is to duct tape the filter to the upper chamber; this will secure the filter, so it doesn’t fall apart in transport. Once the filter is secured in place, use the hacksaw to cut the inlet pipe to access the old amalgam separator’s inlet. After the pipe is removed, turn on the suction to drain the water from the old amalgam separator. Use the provided close out plugs to cap the inlet of the old amalgam separator, tightening the hose clamps on the inlet rubber couple to secure the cap in place. Remove the outlet hose and once again use the provided close out the plug to seal the outlet of the old system. Now that the system is sealed, it is safe to remove your mask.


If your old amalgam separator is wall mounted, use the appropriate screwdriver to remove the mount from the wall. Do not remove the mount, the installation of the mechanical room requires the LibertyBOSS also to be mounted, then, in that case, keep the mount on the wall, and use the appropriate tools to take the old system off the mount.


Once the old amalgam separator has been sealed and removed from the mechanical room, unthread the old hose from the solids collector, located on the inlet of the wet vacuum pump.

Begin the Upgrade

The M.A.R.S Upgrade Kit provides everything that is needed for the installation of a LibertyBOSS amalgam separator. With the M.A.R.S Upgrade Kits, it is always recommended to start with the installation of the outlet, as the length of that hose cannot be changed.

Outlet First

In this installation, there is a dual-headed Air Techniques suction pump, which means the inlet on the solids collector is 1”, requiring the use of the provided bushing. The bushing is included to increase the thread size of the ¾” threaded fitting already attached to the outlet hose, provided in the Wet Upgrade Kit.

outlet hose

Thread the 1” outlet hose into the inlet of the suction pump. Doing a quarter turn counterclockwise will allow the threads to land in the grooves, and minimize the chance of cross threading.

Thread the pre-Teflon tapped nipple into the outlet of the LibertyBOSS, then place it in the location of the mechanical room, you feel is best. Choosing the correct location and the angle in which it will rest may take some trial and error. At this moment, nothing in this install is in their permanent locations.

The provided inlet hose of the Upgrade Kit is adjustable; it is designed this way to allow flexibility in the installation process. Since the inlet hose can be cut to the desired length, it is suggested to choose the LibertyBOSS’ location based on the ease in which you can attach the outlet hose. Once the final location and angle of approach have been decided, use the extra length of the inlet hose to determine how to connect the inlet pipe from the chairs to the inlet of the LibertyBOSS.

Inlet Second

If you are working in a tight space, the provided street elbow can make a cleaner install by providing a more direct route between the pipe and the LibertyBOSS. In the installation for this video, this is the course of action we have chosen.

elbow fitting

When threading any plastic fittings into the LibertyBOSS, it is recommended to first turn counterclockwise to ensure the threads fall into the stainless steel groves. Once you feel the threads have fallen into place, you can turn clockwise to tighten the fittings into the LibertyBOSS. Our next step is to thread the quick connect nipple into the elbow we just attached to the inlet of the LibertyBOSS. Once the nipple is in place, use the other end of the quick connect to connect the inlet hose to the LibertyBOSS. Determine the length of hose needed to connect the LibertyBOSS inlet to the inlet pipe from the chairs.

Occasionally, the quick connect on the hose needs to be adjusted to allow the use of the natural curves of the flexible hose. The advantage of an elbow on the inlet of the LibertyBOSS, you can angle it to allow a more gradual approach into the inlet of the system. If the approach of the LibertyBOSS is in the way of anything in the mechanical room; do not worry. The use of quick connects and a flexible hose allows the LibertyBOSS to be moved temporarily, with very little effort.


You can use the hacksaw to cut the excess hose from the inlet, in this video we used a hose cutter. Slide the rubber couple over the inlet pipe and flexible hose. Using your 5/16 nut driver, tighten both hose clamps on the rubber coupler, making the installation airtight.


At this moment, make any last minute adjustments to the system. Once you are happy with the location of the LibertyBOSS and the installation, check your work by turning on the suction and testing each joint for air loss. Ensure you have locked the arms of the quick connects in place by inserting the provided cotter pins into the locking channels.

Upgrade Completed

With the use of the M.A.R.S Wet Upgrade Kit, it took our M.A.R.S Certified Amalgam Separator Specialist only 15 minutes to complete this installation. It is suspected that any individual should be able to complete this installation in under an hour, less if there isn’t an old amalgam separator to be removed. Please keep in mind, if you hire a Service Technician or a Plumber to complete the installation, using the Upgrade Kit, they may still charge for a full hour installation, as the 15 minutes did not include pre-installation preparations or clean up.
