Accessory Parts - Toshiba MMD-AP0074SPH-E Installation Manual

SMMS Slim Duct Type
Test run
• Before operating the air conditioner after having completed the work, check that the electrical parts 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.
• If there is any kind of trouble (such as an error display has appeared, smell of burning, abnormal sounds, 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 or other trouble.
• After the work has finished, use an insulation tester set (500 V Megger) to check the resistance is 1 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 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.
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 or
other gas 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.
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, do not let water, dust, former refrigerant, or refrigerating oil enter the refrigerating cycle
during installation work.
• 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 (all types can be used) must be used for the power supply line of this conditioner.
