1 PRECAUTIONS FOR SAFETY
Power supply cord of Outdoor unit shall be 2.5mm² (H07RN-F or 245 IEC66) polychloroprene sheathed flexible cord.
•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 trial operation to check for any problem. Follow the Owner’s Manual to explain to the customer how to use and maintain the unit.
•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 AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER.
The characteristics of R410A refrigerant is easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times of refrigerant R22. Accompanied with adoption of the new refrigerant, refrigerating oil has been also changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter into the refrigerating cycle of new refrigerant air conditioner.
To prevent from mixing of refrigerant and refrigerating 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).
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 impurity it.
ENGLISH
CAUTION To Disconnect the Appliance from the Main Power Supply.
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm.
If this is not possible, a power supply plug with grounding must be used. This plug must be easily accessible after installation. The plug must be disconnected from the power supply socket in order to disconnect the appliance completely from the mains.
The installation fuse (25A D type ) must be used for the power supply line of this conditioner.
WARNINGS
•Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
•Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are 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.
•When moving the air-conditioner for installing it in another place again, be very careful not to get the specified refrigerant with any other gaseous body into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high and it resultingly causes burst of the pipe and injuries on persons.

1 PRECAUTIONS FOR SAFETY
•Never modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.
•Exposure of unit to water or other moisture before installation may cause a short circuit.
Do not store it 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.
•To avoid personal injury, be careful when handling parts with sharp edges.
•Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•When installing the air conditioner in a small room, provide appropriate measures to ensure that the concentration of refrigerant in the room does not exceed the critical level should leakage occur.
It is not dangerous refrigerant; it has not toxicity or combustibility. However, a concentration above 0.3kg/m³ as criterion still causes suffocation. The volume of refrigerant charged to the Multi System air conditioner is more than the volume charged to a conventional individual system.
•Install the air conditioner securely in a location where the weight of the unit can be sustained adequately.
•Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
•If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
•After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas may generate.
•The electrical work must be performed by a qualified electrician in accordance with the Installation Manual. Make sure the air conditioner uses an exclusive circuit.
An insufficient circuit capacity or inappropriate installation may cause fire.
•When wiring, use the specified cables and connect the terminals securely to prevent external forces applied to the cable from affecting the terminals.
•Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
•Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
•Do not install the air conditioner in a location subject to a risk of exposure to combustible gas.
Otherwise, the combustible gas leaks, stays around the unit and a fire may occur.
3
2 SELECTION OF INSTALLATION PLACE
WARNING
•Install the air conditioner where there is sufficient strength to withstand the weight of the unit.
If the strength is not sufficient, the unit may fall down resulting in injury.
•Install the air conditioner at a position keeping the height by 2.5m or more from the floor.
If you insert your hands or others directly into the unit during running of the air conditioner, it is dangerous because you may contact with revolving fan or active electricity.
CAUTION
•Do not install the air conditioner in a location subject to a risk of exposure to combustible gas.
Otherwise, the combustible gas leaks, stays around the unit and a fire may occur.
Upon approval of the customer, install the air conditioner in a place that satisfies the following conditions.
•Place where the unit can be installed horizontally.
•Place where a sufficient servicing space can be ensured for safe maintenance and check.
•Place where drained water will not cause any problem.
•Make sure that the user cannot access the unit main body after the installation.
Avoid installing in the following places.
•Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas (hot spring). (Should the unit be used in these places, special protective measures are needed.)
•Place exposed to oil, vapor, oil smoke or corrosive gas.
•Place where organic solvent is used nearby.
•Place close to a machine generating high frequency.
•Place where the discharged air blows directly into the window of the neighboring house. (For outdoor unit)
•Place where noise of the outdoor unit is easy to transmit.
(When installing the air conditioner on the boundary with the neighbor, pay due attention to the level of noise.)
•Place with poor ventilation. (Before air ducting work, check whether value of air volume, static pressure and duct resistance are correct.)

4 AIR DUCTING WORK
Installation Reference
The air supply ducting work is classified into two ways, one is branched by the square ducts, and the other is branched by the round ducts. (Be sure to divide the air supply duct into three or more branches.)
<Square duct> |
<Round duct> |
In case of using the square duct, apply the thermal insulator of thickness by 25mm or more to the duct board. For the thermal insulator, use high-density glass wool of weight by 64kg/m3.
Duct board |
Weight of thermal |
|
insulator (glass wool) is |
|
64 kg/m³ or equivalent. |
|
25mm or more |
In case of using the round duct, use the thermal insulator of thickness by 25mm or more and inner diameter by 150mm or more to the duct board. (If the inner diameter is not enough, resistance generates, as the result, air does not flow smoothly and loss of the static pressure increases.) For the thermal insulator, use high-density glass wool of weight by 24kg/m3 or equivalent.
Weight of thermal insulator (glass wool) is
24 kg/m³ or equivalent.
25mm or more
Ø150mm or more
Connecting method of the duct
1. Supply air side
• Using 6 screws, mount the flange to the supply air port of the indoor unit. (Fig. 1)
‚ Make the square duct according to inner dimension of the flange. A x B .
Use a glass wool board with inside/outside finishing by 25mm-thickness and 64kg/m³-density.
ƒ Connect the flange and each type of duct. (Fig. 2)

2. Return air side
Caution for Safety
When you do not connect the duct to the return air side (using steel and others), apply a protective measures so that your hands or fingers do not directly touch with the motor or other electric parts.
2-1. Return air from rear side
•Follow the procedure same as that for the supply air side. Flange mounting → Square duct making → Connecting work
2-2. Return air from lower side
•Remove the cover for return air at the lower side of the indoor unit, and attach the cover to the opening port at the rear side of the indoor unit.
Cover for return air
‚ Mount the flange to the place from where the cover for return air was removed.
ƒ Mount the square duct.
„ Arrange the flange and the square duct.
