Thank you very much for purchasing TOSHIBA Air conditioner.
Please read this manual carefully before using your PMV Kit.
• When installing an indoor or outdoor unit, follow the installation manual supplied with the unit.
• To connect the PMV Kit to an outdoor unit with pipes, a branching joint or header is required.
Choose one according to the capacity of the units.
ADOPTION OF NEW REFRIGERANT
This air conditioner system is a new type which adopts a new refrigerant HFC (R410A) instead of
the conventional refrigerant R22 in order to prevent destruction of the ozone layer.
Be sure to use an indoor or outdoor unit in combination with the new refrigerant.

1 PRECAUTIONS FOR SAFETY
• Ensure that installation work satisfy all Local, National International regulations.
• Read this “PRECAUTIONS FOR SAFETY” carefully before installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a test operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS PMV KIT 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. Moreover, do not use the existing piping because there are problems with pressure-
resistance force and impurity in it.
