This vacuum cleaner is certified for Gas Group II B which representative gas is Ethylene and its maximum surface temperature is T4 – 135oC. WARNING: The maximum surface temperature of the vacuum cleaner (135oC) must always be lower than the ignition temperature of the gas present in the hazardous area. WARNING: It is the user’s responsibility to conduct a risk assessment in regard to the compatibility of the dusts recovered and the flammable gases, vapors or liquids and other combustible dusts present in the hazardous location.  2.2. APPLICATIONS IN POTENTIALLY EXPLOSIVE ATMOSPHERES IN PRESENCE OF COMBUSTIBLE DUST Tiger-Vac CD 55L EX DT MFS vacuum cleaner: Can be used in ATEX Zone 21 classified areas in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. Can be used in ATEX Zone 22 classified areas in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but – if it does occur – will persist for a short period only. CD 55L EX DT MFS vacuum cleaner can be used to recover combustible dusts such as: Combustible flyings Combustible carbonaceous dusts (Carbon black, charcoal, coal or coke dusts) Flour, grain, wood, plastic and chemicals WARNING: DO NOT RECOVER ANY HOT EMBERS OR IGNITED DUSTS And, based on the application, (See note below): Explosive dusts (ex.: gun powder), combustible metal dusts, including aluminum, magnesium and their commercial alloys, or other combustible dusts whose particle size, abrasiveness, and conductivity present an equivalent hazard WARNING: Empty the recovery tank when necessary but also after every use (8 hours shift). Do not allow recovered materials to sit for extended periods of time. An excessive accumulation of recovered materials can create a dust ignition hazard. NOTE CONCERNING THE RECOVERY OF EXPLOSIVE DUSTS AND OF METAL DUSTS: The applicable standards do not specifically regulate the recovery of combustible dusts and flammable liquids in hazardous areas. For the recovery of explosive dusts and of metal dusts a risk assessment shall be conducted by the user. The following recommendations cannot, in any case, supplant the conclusions of a risk assessment. For the recovery of explosive dusts and of metal dusts: In the case explosive dusts or metal dusts are mixed with other kind of dusts and the quantity of explosive dusts or metal dusts to recover is not significant (ex.: sanding of painted surfaces), or for a maximum of 2 kilos (5 pounds) of conductive dusts or metal dusts the recovered dusts do not need to be rendered inert in a liquid bath. For the specific recovery of a significant quantity of explosive dusts or metal dusts, or for the recovery of more than 2 kilos (5 pounds) of conductive dusts or metal dusts or when these dusts are not mixed with other kind of dusts we recommend the use of an optional “wet mix” immersion separator to precipitate the dusts into a liquid bath. 3.0 VERIFING CORRECT MOTOR ROTATION WARNING: BEFORE OPERATING THE VACUUM SYSTEM VERIFY CORRECT MOTOR ROTATION 1.

A dirty cloth filter will reduce the airflow through and reduce the performance of the vacuum cleaner. Use the manual filter shaker regularly. The cloth filter can also be washed with warm water. A mild detergent can also be used. IMPORTANT: After washing the cloth filter, make sure that it is completely dry before reinstalling it in the filter chamber. Do not reinstall the cloth filter if it is still wet. d. Empty the detachable recovery tank regularly. Do not allow recovered materials to sit for extended periods of time. An excessive accumulation of recovered materials can create a dust ignition hazard. 10.0 CLEANING AND MAINTENANCE WARNING: To reduce the risk of electric shock, disconnect the power supply before performing any servicing or maintenance of the vacuum cleaner a. Empty and clean the detachable recovery tank when necessary, but also after every use (8 hours shift). b. The HEPA filter should be replaced yearly, or every two years, depending on the use. c. Shake the cloth filter regularly to dislodge caked-on dust. d. Wash the cloth filter regularly with warm water. A mild detergent can also be used. IMPORTANT: Make sure that the cloth filter is completely dry before reinstalling it in the filter chamber. a. The cloth filter should be replaced every two or three years depending on use. b. Inspect the cloth filters regularly. If the cloth filters are torn, replace immediately. A torn filter will allow dust and other materials to enter the motor and may cause pre- mature wear of the motor. c. Keep the power supply cable clean and inspect it regularly for cuts or cracks. d. Clean regularly the perforated openings of the motor cabinet and vacuum cleaner surfaces with a water damped cloth to avoid dust accumulation which could create a potential source of ignition. WARNING: Clean the suction hose to remove any accumulated dust, debris or material recovered. Due to the reaction that the remaining recovered material may have with the liquid used, it is the user responsibility to use the proper liquid / procedure to clean the suction hose 11.0 HEPA FILTER REPLACEMENT A HEPA filter is designed for filtration of ultra fine particles. A clogged HEPA filter will reduce the air flow thereby reducing the vacuum’s performance thus requiring replacement. The best indication of a saturated HEPA filter is a noticeable drop in the performance of the vacuum cleaner. For users who wish to implement a conservative protocol for replacing the HEPA filter, it is recommended that the HEPA filter be replaced once a year. NOTE: A second vacuum cleaner, sprays or other power sources are not required for this type of operation in our industry. Proper clothing is, however, required by OSHA for the health and safety of the operator. IMPORTANT: Use only original Tiger-Vac brand replacement HEPA filters. Disconnect the power cable from the outlet. In the Controlled Environment Industry for the recovery of designated substances, changing a filter is considered a low to moderate risk. However, a protective mask and gloves should be worn. The following procedure is valid for both electrically and pneumatically (air) operated vacuum cleaners.  Remove the 3 screws on the HEPA housing using a Philips Screw Driver. Gently remove the housing and place it on the floor. Place a poly liner around the now exposed HEPA filter. Carefully remove the HEPA filter from the back plate. Gently place the HEPA filter into the poly liner. Gently twist the poly liner and then seal it with a tie wrap.  The HEPA filter is now sealed inside of the poly liner and can be disposed of according to local governmental laws. (Conductive poly liners are available.) Substitute the used filter with a new one of the same configuration. WARNING: Do not use the HEPA filter after removal out of the appliance. Apply compound sealant to the inside lip on the rubber side of the filter. Place back the filter housing around the filter and fix it with the 3 screws on the HEPA housing using a Philips Screw Driver. 12.0 MOTOR MAINTENANCE The motor used in this vacuum cleaner is designed for maintenance free operation and it does not need to be serviced.
