When Connecting Refrigerant Tubing
Pay particular attention to refrigerant leakages.
WARNING
•
When performing piping work, do not mix air except for specified refrigerant in
refrigeration cycle. It causes capacity down, and risk of explosion and injury due to
high tension inside the refrigerant cycle.
•If the refrigerant comes in contact with a flame, it produces toxic gases.
•Do not add or replace refrigerant other than specified type. It may cause product
damage, burst and injury, etc.
•Ventilate the room immediately in the event of a refrigerant gas leakage during
installation. Be careful not to allow contact of the refrigerant gas with a flame as this will
cause the generation of toxic gases.
•Keep all tubing runs as short as possible.
•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
•Be sure to turn off the power before servicing.
•Turn the power OFF at the main power box (mains), wait at least 5 minutes until it
is discharged, then open 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.
WARNING
•This product must not be modified or disassembled under any circumstances.
Modified or disassembled unit may cause fire, electric shock or injury.
•Do not clean inside the indoor and outdoor units by users. Engage authorized
dealer or specialist for cleaning.
•In case of malfunction of this appliance, do not repair by yourself. Contact the
sales dealer or service dealer for a repair and disposal.
CAUTION
•Ventilate any enclosed areas when installing or testing the refrigeration system.
Leaked refrigerant gas, on contact with fire or heat, can produce dangerously toxic
gases.
•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 toxic gases.

●If it is necessary to increase the height of the drain pipe, the section directly after the
connection port can be raised a maximum of 500 mm. Do not raise it any higher than
500 mm, as this could result in water leaks.
300 mm or less
500 mm or less

●Do not install the pipe with an upward gradient from the connection port. This will cause the
drain water to flow backward and leak when the unit is not operating.
Upward gradient
Prohibited
●Do not apply force to the piping on the unit side when connecting the drain pipe. The pipe
should not be allowed to hang unsupported from its connection to the unit. Fasten the pipe to
a wall, frame, or other support as close to the unit as possible.
