Operating and Filter Care Instructions
1. Tank assembly is equipped with low intake on outside and 2" tube inside.
2. Carefully open the folds of the disposable collector bag No. 3 and insert into tank.
3. Place the cardboard collar onto the intake tube and carefully pull the collar over the tube until the rubber gasket
is past the ring on the end of the tube.
4. Place the charcoal filter holder assembly No. 2 onto the rim of the tank making sure that the gasket seats fully
around the tank.
5. Place the motor lid assembly No. 1 onto tank, making sure it is seated.
6. Snap on lid latches from tank to vacuum lid.
7. Install hose assembly onto tank intake.
8. Attach vacuum tools to be used.
9. Plug electric cord into wall receptacle and turn on vacuum.
10. With vacuum on, spray anti-static spray (PN 920372) into end of pickup tool. This will coat the tool and hose to
reduce static electricity.
11. Your MRS-6 is now ready for use.
Procedure for Cleaning MRS-6 After Use
1. Remove hose and insert plugs provided at each end.
2. Place hose and tools used into plastic bag and seal with ties.
3. Unplug electric cord and remove vacuum lid from tank assembly.
4. Remove charcoal filter assembly from tank and store in an air tight bag to maximize filter life.
5. Reach into tank and gently push the collar of the filter bag off the tube, seal bag opening with adhesive backed
“Mercury Caution Decal” provided, and carefully remove collector bag from tank.
6. Place collector bag into plastic bags provided.
7. Use dampened disposable wiper towels or cloth to wipe down inside of tank assembly. Place wipers in plastic
bag for disposal.
8. Inside of tank should be checked with “snifter” or comparable air measuring device to determine if all traces of
mercury have been removed. Any mercury residue left in the tank assembly may result in rapid deterioration of
the charcoal filter.
9. Reassemble vacuum according to the Main Assembly. With vacuum assembled and all filters in place, plug in
electric cord and turn vacuum on. Take a snifter reading of the air exhausted around the motor lid assembly to
determine if charcoal filter requires replacing. The highest safe exposure concentration level is 0.05 mg/M3.
Any reading above this level would require a charcoal filter change.
10. Contaminated charcoal filters must be disposed of in the same manner as the collector bag you removed from
the vacuum. Check with your Health/Safety Department for proper disposal procedures. (DO NOT HEAT OR
BURN ANY MERCURY CONTAMINATED ITEMS.)
Options
1. Mercury separator No. 5 with jar No. 6 can be used with MRS-6 for purpose of collecting and separating
mercury from debris.
2. Tank stand No. 7 is required to elevate vacuum when mercury separator is used.
3. Wheel bracket assembly No. 750003 for mounting MRS-6 vacuum is available for increased portability. Wheel
bracket cannot be used with mercury separator and tank stand.
