Consult a qualified installer, service agency, or your distributor or branch for information or assistance. The qualified installer or agency must use factory--authorized kits or accessories when modifying this product. Refer to the individual instructions packaged with the kits or accessories when installing.  \nFollow all local safety codes. Wear safety glasses, protective clothing, and work gloves. Use quenching cloth for brazing operations. Have fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and current editions of the National Electrical Code ( NEC ) and NFPA 70 .  \nRecognize safety information. This is the safety--alert symbol  When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand these signal words; DANGER, WARNING, and CAUTION. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.  \n\n|  ! WARNING |\n| --- |\n| ELECTRICAL SHOCK HAZARD\u003Cbr>Failure to follow this warning could result in personal injury or death.\u003Cbr>Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label. |\n\n\n|  ! WARNING |\n| --- |\n| UNIT OPERATION AND SAFETY HAZARD\u003Cbr>Failure to follow this warning could result in personal injury or equipment damage.\u003Cbr>R--410A refrigerant systems operate at higher pressures than standard R--22 systems. Do not use R--22 service equipment or components on R--410A refrigerant equipment. |\n\nINSTALLATION RECOMMENDATIONS  \nNOTE: In some cases noise in the living area has been traced togas pulsations from improper installation of equipment.  \n1. Locate unit away from windows, patios, decks, and so forth, where unit operation sound may disturb customer.  \n2. Insure that vapor--and liquid--tube diameters are appropriate to capacity of unit.  \n3. Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends.  \n4. Leave some slack between structure and unit to absorb vibration.  \n5. When passing refrigerant tubes through the wall, seal opening with RTV or other pliable silicon--based caulk. (See Fig. 1.)  \n6. Avoid direct tubing contact with water pipes, duct work, floor joists, wall studs, floors, and walls.  \n7. Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap that comes in direct contact with tubing.(See Fig. 1.)  \n8. Ensure that tubing insulation is pliable and completely surrounds vapor tube.  \n9. When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing insulation. (See Fig. 1.)  \n10. Isolate hanger straps from insulation by using metal sleeves bent to conform to shape of insulation.  \nTHROUGH THE WALL  \n~~ ~~JOIST  \nINSULATION  \n~~ ~~ SUCTION TUBE  \n1” MIN  \n~~ ~~ LIQUID TUBE  \nSUSPENSION  \nA07588  \nFig. 1 --- Connecting Tubing Installation  \nGENERAL  \nINSPECT NEW UNIT  \nFile claim with shipping company prior to installation if shipment is damaged or incomplete.
