OPERATING AND FILTER CARE INSTRUCTIONS
The Minuteman Mercury Recovery Vacuums, MRS-1, 2, 3 and 4, have been designed to clean up liquid mercury and mercury
oxide spills. An activated charcoal canister filter is provided to absorb and contain the gas vapor given off by the liquid mercury.
In some applications where the liquid mercury is in the presence of another dry toxic dust material, a U.L.P.A. (Ultra Low
Penetration Air) filter is also used.
Do not at any time attempt to bypass, remove, substitute, or by any other means change the filters recommended for use with
this vacuum. Use only approved Minuteman filters and filter bags.
Do not at any time, or in any way, attempt to clean or remove dust particles that may collect or accumulate on the surface of the
U.L..P.A. filter media.
Do not reverse or attempt to clean “prefilters” which have accumulated dust for the purpose of reusing them.
Since liquid mercury gives off a gas vapor, you are required to remove all traces of it within the vacuum tank assembly and the
mercury separator after each use and prior to storing the vacuum. Any mercury residue left in the vacuum will continue to give
off vapor which will be absorbed by the charcoal filter, thereby reducing the life of the charcoal filter.
Remove disposable collector bag and prefilters at the end of each cleanup period.
The efficiency of your vacuum will be determined by the amount and the density of the material you are vacuuming. All vacuums
will lose efficiency as they become filled. The operator must, therefore, be the one to determine the frequency for emptying and
changing filters based on the efficiency and performance of the vacuum during the cleaning process.
GENERAL INFORMATION
The charcoal filter supplied with your Mercury Recovery Vacuum is a specially activated, impregnated carbon design to increase
the absorbent capacity for mercury vapor gases. The life of the charcoal canister is determined by the volume of mercury vapor
it is exposed to. To maximize the life of the charcoal filter, always store them in an air tight bag when not in use.
The vacuum lid assembly is equipped with a timer which will record actual running time of the unit. The timer is not resetable,
therefore, you are required to keep a permanent log book to indicate each replacement of the charcoal filter.
The log will give the vacuum operator a record of the life span of each filter and approximate time for changes.
Monitoring the exhaust air with vacuum running is the only accurate way to determine the continued efficiency of the
charcoal filter.
When not in use, your Mercury Recovery Vacuum and all its components should be stored in a cool, dry and well ventilated
room. If possible, the room should be vented to outside air. Storing area should not have air return vent leading to air circulating
central system.
