Inspection
Carefully unpack and inspect your machine for shipping damage. Each unit is tested and thoroughly inspected before
shipment and any damage is the responsibility of the delivering carrier who should be notified immediately. Read all
instructions carefully before operating.
WARNING
Electrical shock could occur if used on wet surfaces. Do not expose to rain. Store indoors.
Electrical motors can cause explosions when operated near explosive materials or vapors. Do not operate this machine
near flammable materials such as solvents, thinners, fuels, grain dust, etc.
CAUTION
Hazardous materials must be disposed of properly. Never throw contaminated debris in your usual trash receptacle. Place
debris in a plastic bag or can marked “HAZARDOUS MATERIALS” and take to a hazardous waste handler.
Electrical - 115 Volt
This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. Voltages below 105 AC or above
125 volts AC could cause serious damage to the motor.
Electrical - 240 Volt
This machine is designed to operate on a standard 10 amp. 230 volt, 50 hz, AC circuit.
Grounding Instructions
To protect the operator from electrical shock, this machine must be grounded while in use. This machine is equipped with
an approved three-conductor cord and grounding type plug to fit the proper grounding type receptacle. This machine is for
use on a nominal 120 volt circuit and has a grounding plug that looks like the plug illustrated in sketch A. Make sure that the
machine is connected to an outlet having the same configuration as the plug. No adapter should be used with this machine.
For equipment rated 150-250 volts: If the machine is provided with an attachment plug as shown in sketch B, it is intended
for use on a 240 volt (nominal) circuit. No adapter is available for this plug.
Extension Cords
If an extension cord is used, the wire size must be at least one size larger than the power cord on the machine and must be
limited to 25 feet in length. Extension cord must be three-wire grounded.
Maintenance and Usage
Keep the motor intake cooling air screen clean. If this screen (on top of the motor) becomes clogged, it restricts the flow of
cooling air to the motor and will cause overheating. No lubrication of the motor is required. Machine is equipped with sealed
bearings. For optimum performance, empty and clean filter bag regularly. A clogged and dirty bag restricts the flow of air
and results in reduced vacuum. Check carbon brush periodically. Replace when worn down to approximately 1/2" in length.
Always unplug the machine when removing the motor head off the tank. This will prevent the accidental starting of the motor
and the possibility of fingers or objects getting into the unprotected impeller intake.
CAUTION
The MRS-6 Mercury Recovery Vacuum has been designed for the recovery of liquid mercury or mercury oxides as a result
of spills in small quantities. It should not be used as a conventional vacuum for every day cleaning unless it applies to the
recovery of mercury contaminated debris. When not in use, the machine and all of 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. Always wear the required and proper face mask, gloves and protective
clothing when cleaning up a mercury spill. Check with your Safety Department or your work supervisor if you are not
familiar with the use and procedure for operating a mercury recovery vacuum.
