DO NOT start pump without respirator(s) and hose(s) connected to pump. DO NOT use Vortex type cooled respirators with Allegro pumps. DO check all airline hoses for weakness and wear before use. DO Ensure that all hose and plumbing connections are secure. DO Ensure that the power source conforms to the requirements of your equipment. DO remove aluminum canister on exhaust filter assembly and check that exhaust filter is firmly seated in place before startup. AIR DRIVEN PUMP: (P/N 9850) DO NOT attempt to service the air pump or air motor while it is in operation, and air source connected. DO NOT run air motor with less than 75 cfm at 80 psi. DO NOT run air motor with dirty particulate filter. DO run air motor with inline lubrication properly filled and adjusted. DO make sure that the air pressure and volume conforms to the requirements of your equipment. EXPLOSION PROOF PUMP: (P/N 9833) DO NOT remove plug or cord from motor. Hazardous location plug and receptacle must be used at all times. DO NOT place pump’s inlet filter (or extension) in a hazardous location. DO ensure proper electrical power to motor. DO ensure proper cooling for electrical motor, to avoid heat sources in a hazardous location. NOTE: For further information on how to operate Allegro AABA pumps with various NIOSH approved respirators, please contact our Technical Support Department. WARNING! DO NOT run pump without attaching the breathing hose and respirator. Failure to do so may result in a "back pressure" causing damage and/or stalling the pump. C.G.A. Grade-D Air Requirements Oxygen 19.5 - 23.0 % Hydrocarbons (condensed) in mg/m3 of gas 5 mg/m3 Max. Carbon Monoxide 10 ppm Max. Carbon Dioxide 1,000 ppm Max. No toxic contaminants at levels which would make the air unsafe to breathe. U S E R ’ S I N S T R U C T I O N S 1) Ensure that the pump (or inlet extension filter) is in a clean uncontaminated air environment. o If clean air CANNOT be guaranteed at the pump inlet at all times, use the Inlet extension hose kit (P/N: 9700-65). See instructions on the Inlet extension kit below. 2) Ensure canister on the discharge filter assembly is firmly seated and secure before startup. o Discharge air passes through the HEPA outlet filter located inside the discharged filter assembly. o HEPA filter is NOT for use as protection against vapors and gases. o D.O.P. efficiency: 99.97% (0.3-0.6 micron particles) 3) Attach respirator/hood and air breathing hose to pump. o Check respirator manufacturers’ recommendation for inspection/operation procedures. o Never start pump without hose and respirator attached. o This may result in excessive back pressure that will lead to pump damage. 4) Ensure that air hoses are not tightly coiled or kinked. o This may cause some restriction of the air flow causing the pump to run at a higher PSI and overheat. 5) Plug the pump into proper electrical outlet and turn on the power switch. 6) Properly adjust pressure relief valve. (see instructions for PRV below) o Pumps are designed for multiple users and may require an adjustment to the pressure relief valve to fit the number of workers using the system. 7) Don the respirator as instructed per manufacturer user’s instructions. 8) Ensure all users are receiving sufficient air to the respirator. o Use Allegro P/N 9900-40 “Flow test kit” to verify proper airflow (CFM) to the respirator. o Ambient air pump gauge indicates the dynamic air pressure (back pressure), NOT air volume. 9) Enter work/contaminated area. PRESSURE RELIEF VALVE (RPV): 1) Before making any adjustments check with the respirator manufacturer for the required CFM to that specific respirator. 2) To adjust the relief valve, loosen the lock nut. 3) Turn the adjustment knob counterclockwise to "bleed-off" air. o This will decrease pump output to the respirators. o It is important to set the proper air flow to the respirator, too much air will over work the pump motor, causing it to overheat. Too little air will not provide sufficient air to the user. 4) Turn the adjustment knob clockwise to decrease air being bled off. o This will increase the pressure and air flow to respirators. o Care must be taken to ensure that the respirator and air hose are not disconnected while pump is running, when the PRV is set to this setting. Pump damage will occur. 5) Tighten lock nut. o PRV must be readjusted each time the number of users, respirator type or length of air hose is changed. INLET EXTENSION KIT: (P/N 9700-65) 1) Locate the inlet filter where breathing air CANNOT be contaminated by harmful vap...
