Resumen del manual
Position the metal screen mesh so it is facing upward when the lid is closed. Lid Assembly The F111 lid is held in place by two separable hinges and two spring loaded plungers. To install the spring loaded plungers on the lid follow these steps: 1. Pull the plunger back and twist a quarter turn to reveal the wrench flat on the body of the spring loaded plunger (see Fig 6.) 2. Turn the threaded barrel out of the spring plunger. 3. Insert the threaded barrel through the hole in the lid and turn the spring loaded plunger onto it. 4. Tighten the assembly with wrenches. 5. Repeat steps 1 through 4 for the second plunger. THREADED BARREL SPRING LOADED PLUNGER WRENCH FLAT WRENCH FLAT M11994 Fig. 6. Lid assembly. Opening/Closing the Lid To open the lid, pull the spring loaded plungers back to disengage the plunger. Carefully swing the lid open on the hinges while supporting the filter and/or adsorbent modules as required. To close, swing the lid into the closed position and engage the plungers. Removing /Replacing the Lid IMPORTANT The lid is heavy. Make sure that it is supported before removing. 5 68-0198EF-4 Rev. 11-07 F111 (SERIES 1,2) IN CEILING MEDIA AIR CLEANER To remove the lid, swing it into the open position. Move the lid to the side to disengage the hinge pins. Reverse the procedure to replace the lid. OPERATION The F111 (series 1,2) in Ceiling Media Air Cleaner has been engineered to improve indoor air quality for commercial and industrial applications. The filters are the most practical and effective filtering system for removing atmospheric dust, pollens, bacteria, viruses, mold spores, smoke, fumes, mists and aerosols. Refer to Fig. 7.

F111 (series 1,2) air cleaner operation. The air cleaner is either operating (power on) or off (power off). There are no other operational options available. Even when the area is unoccupied, the air cleaner can be operated continuously to prevent buildup of airborne contaminants. Operate the air cleaner only when the area is occupied when specific activities produce contaminants. The CPZ™ sorbent module has the ability to collect and hold gas-phase compounds and vapors typically found in commercial and light industrial facilities. These gases and vapors frequently appear as odors that, at times, can be annoying and irritating. The modules become saturated after collecting 25% to 50% of their weight in gaseous odors. The quantity of CPZ™ material provides adequate dwell time to ensure up to 95% collection efficiency in the first pass. This also provides a long maintenance-free service life. The minimum recommended air exchange rate is 2.5 times per hour. In a heavily contaminated area, up to 15 air exchanges per hour can be necessary. The factors that determine what the rate of air exchange should be are: • generation rates of the various pollutants; • concentration level of the pollutants; • desired contamination reduction level. Airborne contaminants will always be present in the air where contaminant generations take place. Air cleaning systems and ventilators do not eliminate airborne contaminants, they reduce the excessive accumulation of the contaminants. To eliminate the contamination, the source of contamination must be removed. Local, Federal and professional ventilation engineering standards and codes prescribe minimum ventilation rates to dilute air contamination in specific applications. The ventilation rates usually assume the injection of outdoor air measured as air exchange rate. The use of the F111 (series 1,2) air cleaner to comply with ventilation requirements is an acceptable alternative to ventilation with outdoor air. However, at least 20% of a specified ventilation rate or code must be derived from outdoor air. The F111 (series 1,2) air cleaner filtered and recirculated air can be the remaining 80%. SERVICE CAUTION Electrical Hazard. Can cause personal injury or equipment damage. Turn off power before installing or servicing the air cleaner. IMPORTANT Be sure to change filters as recommended to prevent reduced airflow in the air cleaner.Stand on a stable platform when working with the air cleaner. The useful life of the CPZ™ sorbent modules may vary from 4 to 24 months, depending on the application. In most applications, the sorbent media life ranges from 12 to 18 months. The particle filter life ranges from 6 to 24 months with 12 to 24 months as an average. The modules and filters need to be changed more frequently in facilities that operate 24 hours a day. Prefilter The disposable prefilter collects large dust particulates and lint- type airborne fibers. Check the filter every two weeks to determine the replacement frequency: 1. Slowly open the lid, supporting the lid so the filters do not fall out. 2. Remove the dirty prefilter. 3. Install the n...
