• 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.
When Servicing
• Turn the power OFF at the main power box
(mains) before opening the unit to check or
repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the site after you finish, remembering to
check that no metal scraps or bits of wiring have been
left inside the unit being serviced.

Others
CAUTION
• Ventilate any enclosed areas when installing or
testing the refrigeration system. Escaped refriger-
ant gas, on contact with fire or heat, can produce
dangerously toxic gas.
• Confirm upon completing installation that no refrigerant
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.
• Do not install only a single indoor unit.
• Do not touch the air inlet or the sharp aluminum
fins of the outdoor unit. You may get injured.
• Do not sit or step on the unit, you may fall down
accidentally.
• Do not stick any object into the FAN CASE.
You may be injured and the unit may be damaged.
