BACHARACHHGM-SZThe Measurable DifferenceSingle Zone Halogen MonitorInstruction:3015-5717Revision:0Instructions for Upgrading toDate:November 1,2012an External Charcoal FilterOverviewDuring normal operation,the Single Zone Halogen monitor performs a purge cycle during which fresh air is drawn in from the purgeline to flush internal components of any residual refrigerants.Purge lines should draw in fresh outside air to perform the purgefunction.When access to outdoor air is impractical,purge lines may begin indoors,however a charcoal filter must be used on thepurge line to ensure that no contaminated air is drawn into the system during purge cycles.The charcoal filter removes refrigerantgas contamination from the purge-air stream during the internal purging process.The extema/charcoal filter for the Single Zone monitor is superior to the internal filter used in previous generations of the SZ(whichincluded an intema/charcoal filter).The charcoal filter replacement includes additional components for externally mounting theimproved external charcoal filter.The steps required to perform this upgrade are listed below.Note that this upgrade ONLY appliesto halogen refrigerant monitors(HGM-SZ),and not AGM-SZ(ammonia)or SFM-SZ(SFs)monitors.RequirementsMedium sized Phillips'head screwdriver to open the enclosureWire cutters to remove cable ties holding the internal filterExternal Charcoal Filter upgrade kit P/N 3015-57160Upgrade instructions........(P/N 3015-5717)915-31250Bulkhead fitting ................(P/N 3015-3220)0Elbow fitting.(P/N 3015-3234)o Tubing.….(P/N3015-3164)o T-Bolt bracket..........(P/N 3015-2969)0Charcoal filter ...................(.P/N 3015-3125)Enough customer-supplied tubing to connect the new charcoal filter to the newly-installed bulkhead "Purge Air"connector(maximum length 100 feet;P/N 0304-2743)Appropriate approval for system maintenance of the gas leak monitoring equipmentProcedureStepDescription1.Get approval from the appropriatebuilding management personnel toshut off the gas leak detection andmonitoringequipment and anynetworked building managementcontrols,alarms,and/or gas leakAccess网mitigation equipment.Screws0001Remove power from the Single Zonemonitor.Verify that the unit is off.3.Open the Single Zone (SZ)cabinet byunscrewing the two captive screwslocated on the left side of theenclosure(see Figure 1).Figure 1:Side and Front Views of Single Zone(SZ)Monitor4.Swing open the door to provide access to the internal components of the SZ.
