INSTALLATION INSTRUCTIONSCONDENSATE DRAINSUnits are provided with primary and secondary ¾” NPTdrain connections. Refer to Figure 2 though Figure 7 toidentify the primary and secondary locations. To preventproperty damage and achieve optimum drainageperformance, BOTH primary and secondary drain linesshould be installed and include properly sizedcondensate traps (refer to Figure 14). Factory approvedcondensate traps are available (accessory part numberEBAC01CTK).To connect drain lines, the drain connection knock--outsmust be removed. Use a knife to start the opening nearthe tab and using pliers, pull the tab to remove theknock--out. Clean the edge of the opening if necessary.After drain fittings are installed, caulk the seam betweenthe fitting and the cover to retain the low leak rating of theunit.It is recommended the PVC fittings be used on the plasticcondensate pan. Do not over--tighten. Finger--tightenplus 1½ turns. Use pipe dope, to ensure proper seal.Install traps in the condensate lines as close to the coil aspossible (refer to Figure 16), but avoid blocking filteraccess panel.Install drain lines below the bottom of the drain pan andpitch the drain lines down from the coil at least ¼ inch perfoot of run. Horizontal runs over 15 feet long must alsohave an anti--siphon air vents (stand pipes), installedahead of the horizontal runs. Extremely long horizontalruns may require oversized drain lines to eliminate airtrapping.Route primary drain line to the outside or to a floor drain.Check local codes before connecting to a waste (sewer)line.Route the secondary drain line to a place in compliancewith local installation codes where it will be noticed whenunit is operational. Condensate flowing from secondary(overflow) drain indicates a plugged primary drain -- unitrequires service or water damage will occur.Prime all traps, test for leaks, and insulate drain lineswhere sweating could cause water damage. Consult localcodes for additional requirements or precautions.If a gravity drain cannot be used, install a condensatepump. Install the pump as close to the indoor section aspossible.! CAUTIONPRODUCT or PROPERTY DAMAGE HAZARDFailure to follow this caution may result in productor property damage.Use only full size P -traps in the condensate line(refer to Figure 14). Shallow, running traps are inadequateand DO NOT allow proper condensatedrainage (refer to Figure 15).Figure 14UNITFigure 15Figure 16Fan Coils: FVM2X, FVM4XRecommended Condensate Trap2” MIN2” MINInsufficient Condensate TrapDO NOT USE SHALLOW RUNNING TRAPS!Condensate DrainFILTERACCESSPANELSECONDARY DRAIN WITHAPPROPRIATE TRAP REQUIRED(USE FACTORY KIT ORFIELD -SUPPLIED TRAP)PRIMARY TRAP REQUIRED (USE FACTORY KIT ORFIELD -SUPPLIED TRAP OF PROPER DEPTH.STANDARD P -TRAPS ARE NOT SUFFICIENT.
