9. INSTALLATION PROCEDURE

9-1. Safety Cautions
Power supply cord of parts of appliance for outdoor use
For general public use
shall be more than polychloroprene sheathed flexible cord
(design H05 RN-F), or cord designation 245 IEC 57.
UK PLUGS AND SOCKETS ETC (SAFETY) REGULATIONS 1994,
With regard to Schedule 3, item 7 of the above UK Regulations, this appliance must be permanently
connected to the fixed wiring of the main electrical supply by means other than the use of an
approved 13 Amp plug-top as outlined in the Regulations.
Electrical work must be carried by suitably qualified persons and in accordance with all relevant
safety standards and codes of practice.
We recommend that the power supply for this appliance is derived from a suitably protected
dedicated circuit.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES
NOT DESTROY OZONE LAYER.
R410A refrigerant is apt to be affected by impurity such as water, oxidizing membrane, and oils
because pressure of R410A refrigerant is approx. 1,6 times of refrigerant R22. Accompanied with
adoption of the new refrigerant, refrigerating machine oil has been also changed. Therefore, during
installation work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not
enter into the refrigerating cycle of new-refrigerant air conditioner.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging
port of the main unit or installation tools are different from those for the conventional refrigerant.
Accordingly, the exclusive tools are required for the new refrigerant (R410A) as shown below.
For connecting pipes, use new and clean piping materials with high pressure-tight force, which were
made for R410A only, so that water or dust does not enter. Moreover, do not use the existing piping
because there are problems about pressure-tight force and inner impurity in the existing piping.
CAUTION
To Disconnect the Appliance from the Mains Supply.
This appliance must be connected to the mains by means of a circuit breaker or a switch with a
contact separation of at least 3 mm.
DANGER
Engage Dealer or Specialist for Installation.
• FOR ELECTRICAL WORKS THE WIRING AND CABLES MUST BE PERFORMED IN
COMPLIANCE WITH NATIONAL WIRING STANDARD OR REGULATION.
IF INCORRECT AND INCOMPLETE WIRING IS CARRIED OUT, IT WILL CAUSE AN ELECTRI-
CAL FIRE OR ELECTRICAL SHOCK.
• USE THE SPECIFIED CABLE (1,0mm² or more) AND CONNECT TIGHTLY FOR INDOOR/
OUTDOOR CONNECTION. CONNECT TIGHTLY AND CLAMP THE CABLE SO THAT
EXTERNAL FORCE WILL BE ACTED ON THE TERMINAL.
• WIRE ROUTING MUST BE PROPERLY ARRANGED SO THAT CONTROL BOARD COVER IS
FIXED PROPERLY.
• DO NOT DAMAGE OR SCRATCH THE CONDUCTIVE CORE AND INNER INSULATOR OF THE
CABLES.
• DO NOT DEFORM OR SMASH ON THE SURFACE OF THE CABLES. DO NOT PRESS OR FIX
THE CORD AND CABLES FIRMLY WITH STAPLES, etc.
• DO NOT USE THE INTER-CONNECTING CABLE. NEVER EXECUTE THE CONNECTION OF
WIRING WITH OTHER METHOD THAN THE APPROVED ONE. OTHERWISE, OVERHEAT,
SMOKE OR FIRE MAY BE GENERATED BY CONTACT ERROR.
• TURN OFF MAIN POWER SUPPLY AND BREAKER BEFORE ATTEMPTING ANY ELECTRI-
CAL WORK. MAKE SURE ALL POWER SWITCHES AND BREAKER TURN OFF. FAILURE TO
DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS
CONNECTED BY WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.
SI NUMBER 1768
• GROUNDING WIRE WORKS MUST BE CONSTRUCTED IN COMPLIANCE WITH INSTALLA-
TION MANUAL.
• BE SURE TO USE THE CORD-CLAMPS AND THE UNIT COVER TO THE SPECIFIED
POSITIONS WITH ATTACHED TO THE PRODUCT. MOUNT THE UNIT COVER FOR CABLES
OF CONNECTING SECTION FIRMLY WITH THE SCREWS.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OF GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• IF A REFRIGERATION GAS LEAKS DURING INSTALLATION, BE SURE TO PERFORM
(for U.K. only)
VENTILATION.
IF THE REFRIGERANT GAS COMES INTO CONTACT WITH FIRE, A POISONOUS GAS MAY
OCCUR.
WHEN INSTALLING AN AIR CONDITIONER, DO NOT ALLOW AIR OR MOISTURE TO
REMAIN IN THE REFRIGERATION CYCLE. OTHERWISE, PRESSURE IN THE REFRIGERA-
TION CYCLE MAY BECOME ABNORMALLY HIGH SO THAT A RUPTURE OR PERSONAL
INJURY MAY BE CAUSED.
WARNING
• Never modify this unit by removing any of the safety guards of by-passing any of the safety
interlock switches.
• Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
• Before doing the electrical work, attach an approved cable to the power supply cord.
And make sure the equipment to be earthed.
• For installation, use the tools and piping materials exclusively manufactured for R410A, and
install securely in compliance with this Installation Manual.
Pressure of the used HFC R410A refrigerant becomes higher approx. 1,6 times of that of the
conventional refrigerant. Therefore, if the exclusive piping materials are not used or incomplete
installation is carried out, it may cause a rupture or personal injury, as well water leak, electrical
shock, and a fire may be caused.
• When installing or moving the air conditioner, do not mix air and so on than the specified refrigerant
(R410A) in the refrigeration cycle. If air and so on is mixed, the pressure in the refrigeration cycle may
become abnormally high so that personal injury may be caused by a rupture.
CAUTION
• Exposure of unit to water or other moisture before installation will result in an electrical short.
Do not store in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that
can amplify the noise level of the unit or where noise and discharged air might disturb user's
neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read the installation manual carefully before installing the unit. It contains further
important instructions for proper installation.
• Never install a power capacitor for power factor improvement.
