• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces
of the flare and union tubes before connecting
them, then tighten the nut with a torque wrench for
a leak-free connection.
• Check carefully for leaks before starting the test run.
• Do not leak refrigerant while piping work for an installa-
tion or re-installation, and while repairing refrigeration
parts. Handle liquid refrigerant carefully as it may
cause frostbite.

CAUTION
• Ventilate any enclosed areas when installing or
testing the refrigeration system. Escaped refriger-

gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.

fins of the outdoor unit. You may get injured.
• Do not sit or step on the unit, you may fall down
accidentally.
