*The estimated percentage of cooling capacity that must be subtracted from the Detailed Cooling Capacities data specified in outdoor unit-presale literature for any given indoor/outdoor combination.

†Vapor-line diameter that may be selected for a long-line application. If smaller vapor lines are selected but not specified within the table, large capacity losses will occur and defrost capabilities will be reduced. If larger vapor lines are selected but not specified within the table, refrigerant oil return will be impaired due to velocity losses. N/R— Not recommended due to excessive loss of capacity.

For reference only, the close cell insulation material specified for accessory tubing kits is a compound of vinyl, neoprene, or nitrile blends of these polymers. Performance requirements include thermal range of 0° F to 200°F (-17.8° C to 93° C) and a maximum thermal conductivity of 0.28.

NOTE: Special consideration must be given to isolating intercon- necting tubing from building structure. Isolate tubing so that vibration or noise is not transmitted into structure.

III. METERING DEVICE SIZING

The metering device for a long-line application must be flexible enough to compensate for frictional losses due to long refrigerant

—6—

lines and installed system design (indoor coil above or below outdoor unit.) The piston or TXV provides such flexibility.

The piston should be changed for both indoor coil and outdoor heat pump unit, depending on system configuration and line length. Tables 6 and 7 provide necessary changes for a given application.

Use Tables 6 and 7 when selecting correct piston size. Outdoor- unit presale literature must be consulted to determine metering devices specified for standard applications. After determining standard application piston size(s), refer to Tables 6 and 7 as they relate to system design (outdoor unit above or below indoor unit) per equivalent length of tubing.
