Suction Line Size
• 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.
• For best operation, keep tubing run as short as possible with a minimum num-
ber of elbows or bends.
• Locations where the tubing will be exposed to mechanical damage should be
avoided. If it is necessary to use such locations, the copper tubing should be
housed to prevent damage.
• If tubing is to be run underground, it must be run in a sealed watertight chase.
• Use care in routing tubing and do not kink or twist. Use a good tubing bender
on the vapor line to prevent kinking.
• Route the tubing using temporary hangers, then straighten the tubing and
install permanent hangers. Line must be adequately supported.
NOTES: Using suction line larger than shown in chart will result in poor oil return.
