• Leak detection fluids are suitable for use with most refrigerants but the use of
detergents containing chlorine shall be avoided as the chlorine may react with the
refrigerant and corrode the copper pipe-work.
• If a leak is suspected, all naked flames shall be removed/extinguished.
• If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be
recovered from the system, or isolated (by means of shut off valves) in a part of the
system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through
the system both before and during the brazing process.
When Servicing
• Contact the sales dealer or service dealer for a repair.
• 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

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
gas.

contact with a burning stove, gas water heater, electric room heater or other heat
source, it can cause the generation of toxic gas.
