Detailed Breakdown on the Proper Installation of an Amalgam Separator on a Dry-Vacuum Pump Step 1- Location Part 1

As M.A.R.S’ reach across the North American Dental Industry grows, more Service Technicians and DIY Doctors will need instructions on the proper installation of a LibertyBOSS. M.A.R.S has recently released an installation video on how to install a LibertyBOSS on a dry-vacuum pump. This Blog Series will be breaking down each step of the installation in more detail to offer an in-depth look at the proper installation of a M.A.R.S LibertyBOSS on any dry-vacuum system. These Blogs hope to provide Dental Professionals a better understanding of the process of installing a LibertyBOSS like one of our Certified Amalgam Separator Specialist.

How to Install a LibertyBOSS on a Dry-Vacuum Pump Video

The installation video will be featuring a Midmark PowerVac® G, an excellent dry-vacuum system. The PowerVac® G boasts reducing energy consumption by up to 83%, runs cooler than most dental pumps and sports a fantastic 5-year full product warranty and a 10-year warranty on the pump system. Many LibertyBOSS has been installed on Midmark vacuums and based on M.A.R.S’ experience; they are well-built systems with excellent technical support staff.

This video and some of the instructions will be noting the Midmark PowerVac® G and other dry-vacuum systems; please observe these guidelines will be universal for any dry-vacuum pump. Part 1 of this Blog Series will be focusing on where in the mechanical room you will locate the inlet pipe from chairs.

Step 1: Location, Location, Location

As it is for the installation any amalgam separator, you need to be sure to install your system in the right location of your mechanical room. The wrong placement could result in a suction loss, warranties voided or non-compliance.

Inlet from Chairs

When you are installing an amalgam separator on a dry-vacuum system, it is essential to consider the location of the inlet pipe from chairs. Typically you will find the inlet from your chairs will enter the mechanical room from the floor, as suction lines are usually run through the ground and not the ceiling. If your mechanical room is in a basement or on a lower level than your practice, you may find your inlet from chairs will enter your mechanical room from the ceiling.

Basement/Lower Level Mechanical Room

When you have a mechanical room lower than your office, and you have a dry vacuum system, you will want to consider installing your LibertyBOSS higher than the air/water separator of your pump.

First Install Before and AFter

As you see in the above photo, the LibertyBOSS is installed in between the inlet from chairs and the air/water separator of the dry vacuum systems. The LibertyBOSS is the only amalgam separators sold in North America that can run purely on gravity; it does not require suction to function. By having the LibertyBOSS installed in this manner, it allows remaining water in the evacuation lines to flow naturally through the LibertyBOSS to the air/water separator of your suction pump. By adequately vacating your lines, you can reduce bio-film build up, prevent head weight pushing against the pump, and slowly allow the water to flow through the LibertyBOSS’ internal scrubber that will remove all traces of solid and dissolved mercury.

Main Level Mechanical Room

Typically, a mechanical room on the same floor of the practice will have the inlet from chairs enter from the floor, as you can see in the Proper Installation of a M.A.R.S LibertyBOSS video. When the inlet pipe from the chairs come into the mechanical room from the floor, it is not necessary to wall mount the LibertyBOSS. Since the inlet from the chairs is coming from below, it will not add any strain on the pump to pull the air and water the 19” to enter into the inlet of the LibertyBOSS.


During an application such as this, it is ideal to have a flexible hose installation, as it allows for gradual bends and requires less 90-degree elbows, which will prevent restrictions on the air and water flow. The image below is an example of an amalgam separator installed using a hard pipe, with six 90 degree elbows. This installation was replaced with a LibertyBOSS using a flexible hose, reducing the angles down to one.

Step 1 – Location Part 2

Follow us next week as we continue the proper installation of a M.A.R.S LibertyBOSS on a dry-vacuum pump. In Location Part 2 we will be discussing where amalgam separators belong in the evacuation line system, common mistakes made by Non-C.A.S.S. Service Technicians and space-saving installation tips.
