THERMAL EXPANSION VALVEINSTALLATION INSTRUCTIONSA. INTRODUCTIONThermal expansion valve (TXV) can be used on both heatpump and air conditioning applications. All TXVs have abuilt-in check valve making them heat pump capable. Allare externally equalized with non-adjustable superheatand are available with non-bleed construction. Hard startcapability for outdoor units is required when non-bleedvalve is used. The external equalizer line attached to theTXV has a female flare nut with built in Schrader valvedepressor that attaches to the Schrader valve portprovided on most coils.5.6.B. INSTALLATION NOTESWith reference to Figure 1, the TXV assembly is to beinstalled between the flowrator distributor and theexisting liquid line attached to the flowrator distributor.WARNING: COIL IS PRESSURIZED.RELIEVE PRESSURE BEFORE INSTALLING TXVBY DEPRESSING SCHRADER VALVE ON COILMANIFOLD IF NITROGEN, OR RECLAIMREFRIGERANT IF COIL HAS HOLDING CHARGE.Remove the cap on Schrader valve port on coilmanifold. Attach equalizer tubing with 1/4” femaleflare nut that includes depressor to this male Schraderport. Torque flare nut to 10-30 ft. lb. If using adifferent brand TXV, you must remove theschrader valve core prior to attaching theequalizer tube.Install the TXV bulb to the suction manifold of coil orthe suction line using the two bulb clamps, or singlelarge clamp, furnished with kit.a. Bulb should be installed on a horizontal run ofthe manifold if possible. On line 7/8” OD andsmaller the bulb should be installed at 2 or 10o’clock. With line larger than 7/8” OD, the bulbshould be installed in a position of about 4 or 8o’clock.10 O'CLOCK2 O'CLOCKSENSING BULBSTRAPSUCTION TUBEC. INSTALLATION STEPS ARE AS FOLLOWS:1. After coil pressure has been relieved, turn the femaleswivel nut counter-clockwise to remove.2. Remove the piston from the flowrator distributorfitting using a small diameter wire or paper clip(ALWAYS REMOVE THE PISTON FROMDISTRIBUTOR BODY WHEN TXV ISINSTALLED).3. Attach the TXV by connecting the female swivel nuton TXV outlet to the flowrator distributor (aligningTeflon seal first) and torque swivel nut to 10-30 ft. lb.4. Attach liquid line with female swivel nut to malerotalock fitting on TXV inlet (aligning Teflon sealfirst) and torque swivel nut to 10-30 ft. lb.8 O'CLOCK7/8 O.D. & SMALLER4 O'CLOCKLARGER THAN 7/8 O.D.Horizontal Bulb Locationsb.c.If bulb installation is made on a vertical run, thebulb should be located at least 6 inches from anybend, and on the tubing side opposite the planeof the bend. On vertical bulb installations, thebulb should be positioned with bulb capillarytube at the top.The bulb should be insulated using thermalinsulation to protect it from the effect of thesurrounding ambient temperature.LIQUID LINEzHEX NUTMust be at least6” between elbowand bulbCONECT TOSCHRADER PORTTEFLON SEALTail on bulbMust point upSENSOR BULBTUBEVertical Riser ApplicationEXPANSION VALVE KITFLOWRATOR DISTRIBUTORzLIQUI
