SAFETY DURING REPAIR WORK
1. In order to disassemble and repair
the unit in question, be sure to
disconnect the power cord plug
from the power outlet before starting
the work.
2. If it is necessary to replace any parts, they should be replaced with respective genuine parts for the unit, and
the replacement must be effected in correct manner according to the instructions in the Service Manual of
the unit.
If the contacts of electrical parts
are defective, replace the
electrical parts without trying to
repair them.
3. After completion of repairs, the initial state
should be restored.
4. Lead wires should be connected and laid as
in the initial state.
5. Modification of the unit by user himself should
absolutely be prohibited.
6. Tools and measuring instruments for use in repairs or inspection should be accurately calibrated in advance.
7. In installing the unit having been repaired, be careful to prevent the occurence of any accident such as
electrical shock, leak of current, or bodily injury due to the drop of any part.
8. To check the insulation of the unit, measure the insulation resistance between the power cord plug and
grounding terminal of the unit. The insulation resistance should be 1M or more as measured by a 500V
DC megger.
9. The initial location of installation such as window, floor or the other should be checked for being and safe
enough to support the repaired unit again.
If it is found not so strong and safe, the unit should be installed at the initial location reinforced or at a new
location.
10. Any inflammable thing should never
be placed about the location of
installation.
11. Check the grounding to see whether
it is proper or not, and if it is found
improper, connect the grounding
terminal to the earth.
DANGER
First, I must disconnect
the power cord plug
from the power outlet.

WORKING STANDARDS FOR PREVENTING BREAKAGE OF SEMICONDUCTORS
1. Scope
The standards provide for items to be generally observed in carrying and handling semiconductors in relative
manufacturers during maintenance and handling thereof. (They apply the same to handling of abnormal goods
such as rejected goods being returned).
2. Object parts
(1) Micro computer
(2) Integrated circuits (IC)
(3) Field-effect transistors (FET)
(4) P.C. boards or the like on which the parts mentioned in (1) and (2) of this paragraph are equipped.
3. Items to be observed in handling
(1) Use a conductive container for carrying and storing of parts. (Even rejected goods should be handled in
the same way).
Fig. 1. Conductive Container
(2) When any part is handled uncovered (in counting, packing and the like), the handling person must always
use himself as a body earth. (Make yourself a body earth by passing one M ohm earth resistance through
a ring or bracelet).
(3) Be careful not to touch the parts with your clothing when you hold a part even if a body earth is being
taken.
(4) Be sure to place a part on a metal plate with grounding.
(5) Be careful not to fail to turn off power when you repair the printed circuit board. At the same time, try
to repair the printed circuit board on a grounded metal plate.

Use a high insulation mode (100V, 10M or higher) when ordinary iron is to be used.
(7) In checking circuits for maintenance, inspection or some others, be careful not to have the test probes of the
measuring instrument shortcircuit a load circuit or the like.

1. In quiet operation or stopping the running, slight flowing noise of refrigerant in the refrigerating cycle is
heard occasionally, but this noise is not abnormal for the operation.
2. When it thunders near by, it is recommend to stop the operation and to disconnect the power cord plug
from the power outlet for safety.
3. The room air conditioner does not start automatically after recovery of the electric power failure for
preventing fuse blowing. Re-press START/STOP button after 3 minutes from when unit stopped.
4. If the room air conditioner is stopped by adjusting thermostat, or missoperation, and re-start in a moment,
there is occasion that the cooling and heating operation does not start for 3 minutes, it is not abnormal
and this is the result of the operation of IC delay circuit. This IC delay circuit ensures that there is no
danger of blowing fuse or damaging parts even if operation is restarted accidentally.
5. This room air conditioner should not be used at the cooling operation when the outside temperature is
below –10°C (14°F).
6. This room air conditioner (the reverse cycle) should not be used when the outside temperature is below
–15°C (5°F). If the reverse cycle is used under this condition, the outside heat exchanger is frosted and
efficiency falls.
7. When the outside heat exchanger is frosted, the frost is melted by operating the hot gas system, it is not
trouble that at this time fan stops and the vapour may rise from the outside heat exchanger.
8. This outdoor room airconditioner contain two refregeremt cycle with two compessor separately. Unit 1, 2, 3
and unit 4, 5, 6 are with different cycle
9. Unit 3 and unit 6 has to be connected to ensure no frost or ice remain at bottom of condensor.
10. Unit 2, 3 and unit 5, 6 has to be connected at least to ensure the compessor liability last longer.

Condensed water disposal of outdoor unit
When Using and Installing in Cold Areas
There is holes on the base of outdoor unit for condensed water to exhaust.
To lead condensed water to the drain hole, place the outdoor unit on the mounting stand (optional) or on blocks to raise its
level more than 100mm from the ground surface. Connect the drain pipe as shown in the figure. Cover two other water
drain holes with the bushings included. (To insall a bushing, push in both ends of the bushing so that it aligns with the drain
hole.)
When connecting the drain pipe, make sure that the bushing does not lift off or deviate from the base.
1.Remove flare nut from service valve.
4.Perform air purge and gas leak inspection.
2.Apply refrigerant oil to flare nut sections of servicevalve and pipings.
5.Wrap the provided insulating material around sidepiping using vinyl tape.
3.Match center of piping to large diameter side service valve and tank assembly, and tighten flarenut first by hand,
then securely tighten using torque wrench.
Install the outdoor unit on a stable, flat surface and check to see that the condensed water drains.
For more details, refer to the Installation Manual for Cold Areas.
When the air conditioner is used in low temperature and in snowy conditions, water from the heat exchanger may freeze
on the base surface to cause poor drainage. When using the air conditioner in such areas, do not install the bushings. Keep a
minimum of 250mm between the drain hole and the ground. When using the drain pipe, consult your sales agent.

CAUTION
!
•
To prevent a connection error, connecting cords
should be bundled and taped to each respective
pipe. If connecting cords are mixed with other indoor
units, a refrigeration cycle abnormality may occur,
causing dripping.
When putting two connecting cords through the band.
•Hold the handle of the side cover, slide down and take off the corner hook, then pull. Reverse these steps when installing.
WARNING
!
•
•
Leave some space in the connecting cord for maintenance purpose
and be sure to secure it with the cord band.
Secure the connecting cord along the coated part
of the wire using the cord band. Do not exert
pressure on the wire as this may cause
overheating or fire.
