2 AIRTEX LINEAR HEF-2 RADIANT SYSTEMA irtex Linear panels form a continuous architectural perimeter band constructedto virtually any width from interlocking aluminum extrusions. The thermallyoptimized mechanical bonding technique maximizes heat transfer betweencopper circulating coils and aluminum MODULAR HPH PANELSThe Modular HPH panels are sized to fit ceiling grid openings and incorporatean efficient metallurgical bonding technique between the copper coil andaluminum sheet. The panel face can be custom coloured or silk-screened tomatch adjacent acoustic ceiling tiles. Modular panels may also be providedwith aluminum mounting frames for recessing or surface mounting to gypsumwallboard SYSTEMSAJAIRTEX RADIANT CEILING PANELSCONTENTSPERIMETER HEATING PERFORMANCE (Imperial)PERIMETER HEATING PERFORMANCE (Metric)PRESSURE DROP TABLESGENERAL NOTESAIRTEX HEF-2 LINEAR CEILING OPENING SCHEDULESTANDARD HEF-2 LINEAR EXTRUDED SECTIONSOPTIONAL HEF-2 LINEAR EXTRUDED SECTIONSSINGLE LINEAR PANEL INSTALLATIONMULTIPLE LINEAR PANEL HOOK-UP DETAILSLINEAR RADIANT PANEL CONNECTION DETAILSLINEAR PANEL INSTALLATION AND EXPANSION DETAILSLINEAR PANEL INTERCONNECTION AT CORNERSLINEAR HEF-2 RADIANT PANELS - SCHEMATIC LAYOUTINACCESSIBLE CEILING INSTALLATIONSLINEAR PANELS AT PERIMETER OBSTRUCTIONSSECURITY INSTALLATIONTYPICAL REFLECTED CEILING PANEL ARRANGEMENTSREFLECTED CEILING PANEL ARRANGEMENTS AT COLUMNSTYPICAL PANEL CORNER ARRANGEMENTSPERIMETER INSTALLATION IN A SUSPENDED T-BAR CEILINGINTERIOR INSTALLATION I A SUSPENDED T-BAR CEILINGLINEAR AT PERIMETER OF CEILINGLINEAR PANEL RECESSED FLUSH WITH CEILINGLINEAR PANEL RECESSED UP INTO CEILINGLINEAR PANELS BEHIND DROP BULKHEADINDIVIDUAL SURFACE MOUNTED LINEAR RADIANT PANELSLINEAR PANELS IN SUSPENDED FRAMESSUSPENDED PANEL UNDER EXPOSED

Run-off location may varyfrom mechanical Read radiant panel drawings in conjunction with architectural and mechanical and return piping may have been offset for clarity. Refer to mechanical drawings for pipe sizes andproper locations of main distribution piping, valves and thermostats. For panels installed against an exteriorwall, the first tube supplied should be nearest the Airtex panel lengths have been determined from architectural reflected ceiling plans whenavailable.

Extrusions are suppliedwith copper tubing positioned 7 in. (178mm) from each end unless otherwise noted. Assemble panels fromradiant extrusions as per Assembly and Installation Instructions. All cutting of panels can be done using acircular saw with carbide tip blade for non-ferrous the copper tubing requires cutting:a) Carefully lift copper from saddle and cut back as ) End of tubing can be raised with tube bender (available from supplier).c) Clean heat transfer paste from copper using a solvent before ) Press tubing back into saddle as Care must be taken at all times not to mar or soil panel face.
