Toshiba RAV-SM1403AT-E1 service manual Refrigerant used by this air conditioner is the R410A

Page 8

 

The refrigerant used by this air conditioner is the R410A.

 

 

 

Check the used refrigerant name and use tools and materials of the parts which match with it.

 

For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the

 

outdoor unit where is easy to see. To prevent miss-charging, the route of the service port is changed

 

from one of the former R22.

 

 

 

Do not use any refrigerant different from the one specified for complement or replacement.

 

Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in a

 

failure or explosion of the product or an injury to your body.

 

 

 

For an air conditioner which uses R410A, never use other refrigerant than R410A.

 

For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.

 

If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle

 

and an injury due to breakage may be caused.

 

 

 

Do not charge refrigerant additionally. If charging refrigerant additionally when refrigerant gas leaks,

Refrigerant

the refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner

characteristics or refrigerant over the specified standard amount is charged and an abnormal high

 

pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury.

 

Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming,

 

and then newly recharge the specified amount of liquid refrigerant. In this time, never charge the

 

refrigerant over the specified amount.

 

 

 

When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than

 

R410A into the specified refrigerant. If air or others is mixed with the refrigerant, abnormal high

 

pressure generates in the refrigerating cycle resulted in cause of injury due to breakage.

 

 

 

After installation work, check the refrigerant gas does not leak. If the refrigerant gas leaks in the room,

 

poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though

 

the refrigerant gas itself is innocuous.

 

 

 

Never recover the refrigerant into the outdoor unit. When the equipment is moved or repaired, be sure

 

to recover the refrigerant with recovering device. The refrigerant cannot be recovered in the outdoor

 

unit; otherwise a serious accident such as breakage or injury is caused.

 

After repair work, surely assemble the disassembled parts, and connect and lead the removed wires

 

as before. Perform the work so that the cabinet or panel does not catch the inner wires. If incorrect

Assembly/

assembly or incorrect wire connection was done, a disaster such as a leak or fire is caused at user’s

side.

Cabling

 

 

After the work has finished, be sure to use an insulation tester set (500V Megger) to check the

 

resistance is 1MΩ or more between the charge section and the non-charge metal section

 

(Earth position). If the resistance value is low, a disaster such as a leak or electric shock is caused at

Insulator check

user’s side.

 

 

 

When the refrigerant gas leaks during work, execute ventilation. If the refrigerant gas touches to a fire,

 

poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is

 

dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.

 

 

 

If refrigerant gas has leaked during the installation work, ventilate the room immediately.

Ventilation

If the leaked refrigerant gas comes in contact with fire, noxious gas may be generated.

 

After the installation or servicing work, confirm that refrigerant gas does not leak. If refrigerant gas

 

 

leaks into the room and flows near a fire source, such as a cooking range, noxious gas may be

 

generated.

 

 

 

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. Excessive tighten of the flare nut

Compulsion

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.
