Toshiba RAV-SM566BT-E, RAV-SM406BT-TR service manual though the refrigerant gas itself is innocuous

	When the refrigerant gas leaks, find up the leaked position and repair it surely.
	If the leaked position cannot be found up and the repair work is interrupted, pump-down and
	tighten the service valve, otherwise the refrigerant gas may leak into the room.
	The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove
	though the refrigerant gas itself is innocuous.
	When installing equipment which includes a large amount of charged refrigerant such as a multi
	air conditioner in a sub-room, it is necessary that the density does not the limit even if the
	refrigerant leaks.
	If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.
	Tighten the flare nut with a torque wrench in the specified manner.
Compulsion	Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may
	result in refrigerant leakage.
	Nitrogen gas must be used for the airtight test.
	The charge hose must be connected in such a way that it is not slack.
	For the installation/moving/reinstallation work, follow to the Installation Manual.
	If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or
	fire is caused.
	Once the repair work has been completed, check for refrigerant leaks, and check the insulation
	resistance and water drainage.
	Then perform a trial run to check that the air conditioner is running properly.
	After repair work has finished, check there is no trouble. If check is not executed, a fire, electric
	shock or injury may be caused. For a check, turn off the power breaker.
Check after
	After repair work (installation of front panel and cabinet) has finished, execute a test run to check
repair
	there is no generation of smoke or abnormal sound.
	If check is not executed, a fire or an electric shock is caused. Before test run, install the front
	panel and cabinet.
	Check the following matters before a test run after repairing piping.
	Connect the pipes surely and there is no leak of refrigerant.
	The valve is opened.
Do not	Running the compressor under condition that the valve closes causes an abnormal high
operate the	pressure resulted in damage of the parts of the compressor and etc. and moreover if there is
unit with the	leak of refrigerant at connecting section of pipes, the air is suctioned and causes further
valve closed.	abnormal high pressure resulted in burst or injury.
	Only a qualified installer (∗1) or qualified service person (∗1) is allowed to relocate the air
	conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual
	since a fire, electric shocks, injury, water leakage, noise and/or vibration may result.

Check the following items after reinstallation.

1)The earth wire is correctly connected.

2)The power cord is not caught in the product.

3)There is no inclination or unsteadiness and the installation is stable. Check after If check is not executed, a fire, an electric shock or an injury is caused.

reinstallation
	When carrying out the pump-down work shut down the compressor before disconnecting the
	refrigerant pipe.
	Disconnecting the refrigerant pipe with the service valve left open and the compressor still
	operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to
	an abnormally high level, and possibly resulting in reputing, injury, etc.
	When the service panel of the outdoor unit is to be opened in order for the compressor or the
	area around this part to be repaired immediately after the air conditioner has been shut down, set
	the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the
	service panel.
	If you fail to heed this warning, you will run the risk of burning yourself because the compressor
	pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair
	work, wear the kind of insulated heat-resistant gloves designed to protect electricians.
Cooling check	When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor,
	inverter or the areas around these parts to be repaired immediately after the air conditioner has
	been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes
	before opening the service panel.
	If you fail to heed this warning, you will run the risk of burning yourself because the fan motor,
	reactor, inverter heat sink and other parts will be very hot to the touch.
	In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant
	gloves designed to protect electricians.
