Carefully read this chapter to learn the requirements for your installation site: The support requirements. The location and air current requirements. The electrical power requirements.
Chapter 2: Prerequisites Location and Air Current Requirements The Fume Adsorbers have been designed to contain hazardous fumes by negating typical cross drafts and turbulence within the opening. As precautionary safety measure and a higher level of quality management, it is recommended that the Fume Adsorber be placed in an area to avoid: High traffic areas where walking might cause an air disturbance or be a nuisance.
CHAPTER 3 GETTING STARTED Now that the site for your Fume Adsorber is properly prepared, you are ready to unpack, inspect and install the enclosure. Read this chapter to learn how to: Unpack and move the enclosure. Set up the enclosure with the proper supporting structure. Installation of carbon filter(s). (Fume Adsorbers ship with organic vapor filter(s). Connect the electrical supply. Validate the enclosure face velocity.
Chapter 3: Getting Started Installing the Enclosure on a Supporting Structure Use caution when lifting or moving the enclosure. When installing the enclosure onto a chemical-resistant work surface or benchtop, ensure that the structure can safely support the weight of the enclosure. The 30" wide Fume Adsorber weighs 62 lbs, and the 60" wide Fume Adsorber-2 weighs 125 lbs. The work surface should be at least as wide as the enclosure to properly support it.
Chapter 3: Getting Started Connecting the Electrical Supply Source to the Enclosure 115V Maximum circuit load is 2 amps. 230V Maximum circuit load is 1 amp. 115V Models Simply connect the 115V power cord supplied to the IEC electrical supply plug on the back of the enclosure. 230V Models The same procedure applies for the 230V except it is shipped without a plug. Install the appropriate plug for your electrical specifications per local codes.
CHAPTER 4 PERFORMANCE FEATURES AND SAFETY PRECAUTIONS Performance Features The Fume Adsorbers are designed to meet the needs of the laboratory scientist and provide containment of light emissions of solvents, formaldehyde and ammonia vapors. Annoying vapors, such as xylene and toluene fumes used in cover slipping operations are efficiently adsorbed by the Fume Adsorber carbon filter(s). The Fume Adsorber uses a carbon filter to collect low concentrations and exhaust filtered air back into the room.
Chapter 4: Performance Features & Safety Precautions 1 3 2 5 Figure 4-2 Performance Features, Exploded View 1. Built-In Motorized Impeller Provides up to 35 fpm average face velocity. Airflow capacity is 100 CFM on the 30" wide unit and 200 CFM on the 60" wide unit. 2. Perforated Baffle provides uniform removal of noxious fumes. Remove this baffle to access the carbon filter. 3.

CHAPTER 5 APPROPRIATE APPLICATIONS FOR YOUR ENCLOSURE Now that the installation of your enclosure is completed, you are ready to use your Fume Adsorber. Read this chapter to learn about: 1. 2. 3. 4. 5. 6. 7. Routine Daily Work Procedures. Suitable Applications. Appropriate Chemicals for Carbon Filters. Definition of Terms. Hazardous Misapplications for Carbon Filters. Chemical Carcinogen use with Carbon Filters. Prohibited Acid Use. Start-up Turn on exhaust system blower with the ON/OFF switch.
Chapter 5: Appropriate Applications for Your Enclosure Shutdown Turn off the exhaust system blower with the ON/OFF switch. Suitable Applications NIOSH (National Institute for Occupational Safety and Health, USA) has established guidelines for chemical cartridge and HEPA filtered respirators. Suitable applications for the carbon filtered enclosures are based on guidelines below. As with respirators, chemical contaminants are adsorbed or treated by carbon.
Chapter 5: Appropriate Applications for Your Enclosure Organics must have time weighted exposure limits (TWA) of 100 PPM or greater. Chemicals must have a detectable odor at concentrations below the TWA for the chemical. Chemicals must be designated by NIOSH guidelines as acceptable for use with chemical cartridge-type respirators (the exception is formaldehyde and ammonia/amines, which used impregnated carbon).
Chapter 5: Appropriate Applications for Your Enclosure IDLH (Immediately Dangerous to Life and Health). An atmosphere that poses an immediate hazard to life or produces immediate irreversible health effects. IDLH concentrations should not be approached in the enclosure. Carbon Hazardous Misapplications for Carbon Filters with Volatile Chemicals There is one scenario where the accessory carbon filter misapplication would be a part of a hazardous condition.
CHAPTER 6 MAINTAINING YOUR ENCLOSURE Monitoring airflow and changing the carbon filters (if equipped) is the primary maintenance required. Review this chapter on maintenance for the following: 1. Routine Maintenance. 2. Determination of when to replace carbon filters and how to replace. 3. Calculating carbon filter life.
