Modus Programming Instructions1.) Programming the Alarm Set pointsAfter the first press of MODE, the HI LED flashes, indicating the HI set point is being entered. Theleast significant digit (right hand) should be flashing. Press the ARROW key to scroll to thedesired digit (0 through 9). Press the MODE to move towards the most significant digit and press theARROW key set each remaining digit’s value. The sign of the set point (+ or -) is selected last.After the HI set point has been programmed, press the MODE to enter the LO set point. The LOalarm LED flashes, and you can repeat the above process to program the LO set point.2.) Programming the Relay Dead bandThe dead band selection is provided to keep the relays from chattering when the pressure varies nearthe set point. To display the dead band, press MODE once after setting the LO set point polarity inthe previous step. Both alarm LEDs flash. The three digits displayed are the dead band width, in thesame units used for data display. Press the MODE and ARROW keys as described earlier to set thedead band to a value of .002.3.) Returning to Normal OperationPress MODE once after the setting the dead band parameters. The digit “1” on the left indicates theunit is in analog setting mode. Since there are no analog outputs, the MODE key can be pressed afinal time to end programming and return to the normal pressure display.Page 21 of 54
Maintenance NotesWARNING!Before any panels are removed, the cabinet must be decontaminated.Also see section 2 “Decontamination”The filters are sure to have collected microorganisms and other potentially harmful particles generated from thework area during their lifespan. Maintenance personnel should not allow themselves to be exposed.It should also be remembered that a specific gaseous decontaminant may work against microorganisms, butnot against chemical agents. Where chemical agents are present, consult an industrial hygienist or other qualifiedperson(s).Replacing the HEPA FilterIf the differential pressure monitor presents an alarm, or if your periodic checks of total airflow show adrop of more than 5% of the nominal set point, the filters may be loading with particulates. As explainedearlier in this section, the blower speed can be manually increased to compensate for filter loading.However, when the airflow can no longer be maintained or when the filters are damaged, they need to bereplaced.A contaminated filter must be handled with caution. Personnel should be protected by clothing orbreathing apparatus as necessary to the nature of the hazard. It is advisable to seal the contaminated side ofthe filter by taping a plastic sheet or cardboard over the face before removal. This should minimize thenumber of particles shaken loose from the filter. Once removed, the filter should immediately be sealed in abiological hazard bag and then disposed of safely in accordance with environmental regulations.After filter replacement has been completed, the cabinet and the room should be cleaned anddecontaminated in a manner consistent with the nature of the hazardous material. The cleaning materials,along with the protective gear and clothing, should be properly disposed of.HEPA filters are very easily damaged, and you will want to use great care during handling so as to avoidinjury to the filter media and gasket surface. When installing the new filters, it is a good idea to tape a pieceof cardboard over the filter media to give protection against dropped wrenches or misdirected fingers. Ofcourse, you will need to make sure that the cardboard is removed before the access panels are re-installed.Inspect the filters carefully before and after installation. A broken or damaged filter is worthless.Changing the Exhaust FilterThe BIOPROtect II requires two exhaust filters measuring 19” x 38” x 12” deep (consult test reportfor part numbers and specifications).These filters are arranged to face the front of the unit so as toeliminate the nuisance of ceiling restrictions on the exhaust air.To service the exhaust filter remove the panels from the front of the unit using a 3/8” nut driver orsocket to remove the ¼-20 hardware. Using the same 3/8” driver, remove the hardware from the filtersecuring frame. Pull the frame and filter away from the unit.Prepare the new filters by putting a light coat of silicone grease on the face of the gasket. Clean thesealing flange thoroughly. Then carefully slide the new filter into place and make sure that it is properlyseated on the flange. Replace the filter clamp assembly and perform the leak test described earlier in thischapter.Page 22 of 54
