Refrigerant Planning Values
Planning for the refrigerant requirements of the completed system is the addition of the charges from
Indoor Unit, Condenser (including Lee-Temp receiver, if used) and the interconnecting piping.
Tables 3 and 4 provide the approximate charge required for the condensers and the interconnecting
piping. Consult indoor unit manuals for indoor unit charge requirements.
These values can be used for obtaining adequate refrigerant for the system, but should not be used for
These values can be used for obtaining adequate refrigerant for the system, but should not be used for
final charging. Consult indoor unit manual for charging procedures.
