• Blow out the liquid and vapor lines with dry nitrogen before connecting to the
outdoor unit and indoor coil. Any debris in the line set will end up plugging the
expansion device.
• As an added precaution, a high quality filter drier is standard on R-410A units.
• Do not allow the vapor line and liquid line to be in contact with each other. This
causes an undesirable heat transfer resulting in capacity loss and increased
power consumption. The vapor line must be insulated.
• If tubing has been cut, make sure ends are deburred while holding in a position
to prevent chips from falling into tubing. Burrs such as those caused by tubing
cutters can affect performance dramatically, particularly on small liquid line
sizes.
