*The required superheat chart is an example of a generic superheat chart of a typical fixed
orifice, split residential system. The required subcooling chart is an example of a typical
chart for a TXV, split 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.
CLEANING THE SENSOR
(SEE FIG. D)
Observe the gasket after each vacuum. If oil is present, it is possible that there is a
presence of oil in the sensor chamber.
Follow these instructions:
1. Disconnect the sensor chamber from the socket.
2. Remove the gasket & depressor from the assembly to clean.
3. Clean the gasket. Rinse the sensor chamber with acetone. Repeat until the oil is
completely removed. Allow 2 – 4 hours for all of the parts to dry.
4. Reassemble all of the parts and check the unit.
