(24.38 and 60.96 m) horizontal or 35 ft. (10.7 m) vertical differential (total equivalent length), refer to theResidential Piping and Long Line Guideline.Make Piping Connections! WARNINGPERSONAL INJURY AND ENVIRONMENTALHAZARDFailure to follow this warning could result in personal injuryor death.Relieve pressure and recover all refrigerant before systemrepair or final unit disposal. Use all service ports and openall flow--control devices, including solenoid valves.Federal regulations require that you do not vent refrigerantto the atmosphere. Recover during system repair or finalunit disposal.CAUTION!UNIT DAMAGE HAZARDFailure to follow this caution may result in equipmentdamage or improper operation.If ANY refrigerant tubing is buried, provide a 6--in (152.4mm) vertical rise at service valve. Refrigerant tubing lengthsup to 36--in (914.4 mm) may be buried without furtherspecial consideration. Do not bury lines more than 36--in.(914.4 mm).Outdoor units may be connected to indoor section using accessorytubing package or field--supplied refrigerant grade tubing of correctsize and condition. Rated tubing diameters shown in Table 2 arerecommended up to 80 ft. (24.38 m). See Product Data foracceptable alternate vapor diameters and associated capacity losses.For tubing requirements beyond 80 ft. (24.38 m), substantialcapacity and performance losses can occur. Following therecommendations in the Residential Piping and LonglineGuideline will reduce these losses. Refer to Table 2 for field tubingdiameters. Refer to Table 1 for accessory requirements.There are no buried--line applications greater than 36--in. (914.4mm) allowed.If refrigerant tubes or indoor coil are exposed to atmosphere, theymust be evacuated to 500 microns to eliminate contamination andmoisture in the system.Outdoor Unit Connected to Factory Approved IndoorUnitOutdoor unit contains correct system refrigerant charge foroperation with factory approved AHRI rated indoor unit whenconnected by 15 ft. (4.57 m) of field--supplied or factory--accessorytubing, and factory supplied filter drier. Check refrigerant chargefor maximum efficiency.NOTE: If the indoor furnace coil width is more than the furnacecasing width, refer to the indoor coil Installation Instructions fortransition requirements.! WARNINGUNIT OPERATION AND SAFETY HAZARDFailure to follow this warning could result in personal injuryor equipment damage.PuronR refrigerant systems operate at higher pressures thanstandard R--22 systems. Do not use R--22 service equipmentor components on PuronR refrigerant equipment.Refrigerant Tubing Connection OutdoorConnect vapor and liquid tubes to fittings on vapor and liquidservice valves (see Table 2.) Use refrigerant grade tubing.Table 2 – Refrigerant Connections and Recommended Liquidand Vapor Tube Diameters (In.)UNIT SIZELIQUID RATED VAPOR*Connection& Max.
