When Connecting Refrigerant Tubing
WARNING
•  When performing piping work do not 
mix air except for specified refrigerant
(R410A) in refrigeration cycle. It 
causes capacity down, and risk of 
explosion and injury due to high 
tension inside the refrigerant cycle.
• Refrigerant gas leakage may cause 
fire.
Do not add or replace refrigerant other 
than specified type. It may cause 
product damage, burst and injury, etc.
•
• Ventilate the room well, in the event that is 
refrigerant gas leaks during the installation. 
Be careful not to allow contact of the 
refrigerant gas with a flame as this will 
cause the generation of poisonous gas.
• Keep all tubing runs as short as possible.
• 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 installation 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.

Do not touch the air inlet or 
the sharp aluminum fins of the 
outdoor unit. You may get injured.
Ventilate any enclosed areas when 
installing or testing the refrigeration 
system. Escaped refrigerant gas, 
on contact with fire or heat, can 
produce dangerously toxic gas.
• 
Confirm after installation that no 
refrigerant gas is leaking. If the gas 
comes in contact with a burning 
stove, gas water heater, electric 
room heater or other heat source,
it can cause the generation of 
poisonous gas.
