1. Precautions
1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact
replacement parts. (Also, we recommend
replacing parts rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
equipment may cause problems laterintermittent contact, for example.
Fig. 1-1 Avoid Dangerous Contact
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance, Procedure:
Prior to applying power, measure the
resistance between the power cord and the
ground terminal. The resistance must be
greater than 30 megohms.
Fig. 1-2 No Tapping and No Extension Cords
7. Make sure that the grounds are adequate.
8. Make sure that the installation conditions
are satisfactory. Relocate the unit if
necessary.
9. Keep children away from the unit while it is
being repaired.
10. Be sure to clean the unit and its surrounding
area.

3. Installation and Operating Instructions
3-1 Installation
* When selecting the area for installing the unit, be sure to obtain approval of the customer.
1.
Make sure that you install the unit in an area that
provides good ventilation.
The air conditioner must not be blocked by any
obstacle affecting the air flow near the air inlet and
air outlet.
2.
Make sure that you install the unit in an area which
can endure the weight and vibration of the unit.
3.
Make sure that you install the unit away from heat
or vapor.
4.
Make sure that you install the unit in an area where
the cooled(heated) air can be evenly spread in a
room.
5.
Make sure that you install the unit in an area away
from TVs, audio units, cordless phones, fluorescent
lighting fixtures and other electrical appliances.
(obtain a clearance of at least one meter)
6.
Make sure that you install the unit in an area which
provides easy drainage for condensed water.
7. Make sure that you install the unit in an area not
exposed to rain or direct sunlight.
(Install a separate sunblind if exposed to direct sunlight.)
8.
Do not install the unit in an area subjected to noise
or vibration amplification which may affect your
neighbor.
(Fix the unit firmly if mounted in a high place.)
Caution:
Do not use the air conditioner in such areas as a greasy area(including machine oil),
saline area(sea side), or sulphuric area(hot spring). When using the air conditioner in these areas,
special maintenance is required. Contact your local dealer or our service center for advice.
