Install liquid flare-to-sweat adapter. 3. Install TXV on liquid flare-to-sweat adapter. 4. Connect external equalizer tube to fitting on suction tube adapter. 5. Position sensing bulb on horizontal portion of suction tube adapter. Secure using supplied hardware. Insulate bulb after installation. (See Fig. 6.) 6. Leak check all connections. DO NOT BURY MORE THAN 36 IN. OF REFRIGERANT TUBING IN GROUND. If any section of tubing is buried, there must be a 6-in. vertical rise to the valve connections on the outdoor unit. If more than the recommended length is buried, refrigerant may migrate to cooler buried section during extended periods of unit shutdown, causing refrigerant slugging and possible compressor damage at start-up. Step 5—Install Liquid Solenoid Valve (LSV)— Optional Heating efficiency (HSPF) can be improved with the addition of a LSV. Refer to presale literature for rating with this enhancement. Install per Installation Instructions included in accessory kit part number KHALS0101LLS. NOTE: To enhance heating HSPF, flow arrow must point toward outdoor coil. Step 6—Make Piping Connections Outdoor units may be connected to indoor sections using accessory tubing package or field-supplied refrigerant grade tubing of correct size and condition. For tubing requirements beyond 50 ft, consult Long-Line Application Guideline which is available at your local distributor. In some cases noise in the living area has been traced to gas pulsations from improper installation of equipment. INSTALLATION RECOMMENDATIONS 1. Locate the unit away from windows. 2. Ensure that vapor and liquid tube diameters are appropriate to the capacity of the unit. (See Table 1.) 3. Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends. 4. Leave some slack between the structure and the unit to absorb vibration. 5. When passing refrigerant tubes through the wall, seal the opening with RTV or other pliable silicon-based caulk. (See Fig. 3.) 6. Avoid direct lineset contact with water pipes, ductwork, floor joists, wall studs, floors, and walls. 2 7. Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with the tubing. (See Fig. 3.) 8. Ensure that tubing insulation is pliable and completely surrounds the vapor tube. 9. When necessary, use hanger straps which are 1 in. wide and conform to the shape of the tubing insulation. (See Fig. 3.) 10. Isolate the hanger straps from the insulation by using metal sleeves bent to conform to the shape of the insulation. If refrigerant tubes or indoor coil is exposed to atmospheric conditions for longer than 5 minutes, it must be evacuated to 500 microns to eliminate contamination and moisture in the system. OUTDOOR UNITS CONNECTED TO FACTORY-APPROVED INDOOR UNITS — Outdoor unit contains correct system refrigerant charge for operation with indoor unit of the same size when connected by 15 ft of field-supplied or factory accessory tubing. Check refrigerant charge for maximum efficiency. (See Step 10—Checking Charge.) REFRIGERANT TUBING — Connect refrigerant tubing to fittings on outdoor unit vapor and liquid service valves.

For tubing lengths greater than 50 ft, consult Long-Line Application Guideline. To avoid valve damage while brazing, service valves must be wrapped with a heat sinking material such as a wet cloth. SWEAT CONNECTION — Use refrigerant grade tubing. Service valves are closed from factory and ready for brazing. After wrapping the service valve with a wet cloth, the tubing set can be brazed to the service valve using either silver bearing or non-silver bearing brazing material. Remove plastic retainer holding outdoor piston in the liquid service valve and connect sweat adapter provided to valve. (See Fig. 7.) Consult local code requirements. Refrigerant tubing and indoor coil are now ready for leak testing. This check should include all ...
