residential system. These charts should not be used for charging. They are only examples to show what
the manufacturer's charts may look like. Follow all manufacturer's indications, instructions and warnings
above those in this manual.
The indoor wet bulb measurement should be taken as close to the evaporator coil inlet as
possible. The outdoor dry bulb reading should be taken as close to the condenser air inlet as
possible.
