Accessory Parts - Toshiba RAV-SM2242DT-E Installation Manual

Test run
• Before operating the air conditioner after having completed the work, check that the electrical control box cover of the
indoor unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may
receive an electric shock if the power is turned on without first conducting these checks.
• When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of
burning, abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the
air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a
qualified service person. Take steps to ensure that the power will not be turned on (by marking "out of service" near
the circuit breaker, for instance) until qualified service person arrives. Continuing to use the air conditioner in the
trouble status may cause mechanical problems to escalate or result in electric shocks, etc.
• After the work has finished, be sure to use an insulation tester set (500V Megger) to check the resistance is 2 MΩ or
more between the charge section and the non-charge metal section (Earth section). If the resistance value is low, a
disaster such as a leak or electric shock is caused at user's side.
• Upon completion of the installation work, check for refrigerant leaks and check the insulation resistance and water
drainage. Then conduct a test run to check that the air conditioner is operating properly.
Explanations given to user
• Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does not know
where the circuit breaker is, he or she will not be able to turn it off in the event that trouble has occurred in the air
conditioner.
• If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to
the OFF position, and contact a qualified service person(*1) to have the repairs done. Do not set the circuit breaker
to the ON position until the repairs are completed.
• After the installation work, follow the Owner's Manual to explain to the customer how to use and maintain the unit.
Relocation
• 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.
• 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 rupture, injury or other trouble.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
CAUTION
New refrigerant air conditioner installation
• This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also
been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does
not enter the refrigerating cycle.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of
the main unit and installation tools are changed from those for the conventional refrigerant.
• Accordingly the exclusive tools are required for the new refrigerant (R410A).
• For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not
enter.
To disconnect the appliance from main power supply.
• This appliance must be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm.
The installation fuse must be used for the power supply line of this conditioner.
