CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.) 3) Specification of power source. 4) Confirm that electrical capacity is sufficient. 5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 6) Confirm that the cable thickness is as specified in the power source specification. (Particularly note the relation between cable length and thickness.) 7) In a wet or moist area, always install an earth leakage circuit breaker. 8) The following would be caused by voltage drop. Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the normal function of the overload. 9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 3mm in each active(phase) conductors Product Data 43

61 8. Installation 8.5 Indoor Unit Drain Piping Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. The outside diameter of the drain connection on the indoor unit is 32mm. Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings Be sure to install heat insulation on the drain piping. Heat insulation material: Polyethylene foam with thickness more than 8 mm. Drain test Pipe clamp Indoor unit Maintenance drain port Upward routing not allowed 1/50~1/100 MAX 700mm The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation: Feed water Drain Pump Drain pan CAUTION Flexible drain hose (accessory) Main drain pipe Drain port Glue the joint Drain hose connection Use the clip (accessory) The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water. Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end. Feed water to the flexible drain hose and check the piping for leakage. Be sure to check the drain pump for normal operating and noise when electrical wiring is complete. When the test is complete, connect the flexible drain hose to the drain port on the indoor unit. Flexible drain hose 1/50~1/100 MAX 700mm CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Never fail to equip a leakage breaker where it is wet or moist. 9) The following troubles would be caused by voltage drop-down. Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. Proper starting power is not given to the compressor. 60 MPS(Multi Power System) Variable Multi

In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc. In these cases, take the following actions: Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner. Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam. 2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc. 3. Avoid places where inflammable gas is generated, flows in, is stored or vented. 4. Avoid places where sulfurous acid gas or corrosive gas is generated. 5. Avoid places near high frequency generators. 74 MPS(Multi Power System) Variable Multi

148 2. Central Control 2.2. Deluxe Central Control(PQCSW501A0, PQCSW502A0) Introduction SUMMARY Deluxe Central control is a product available for individual and integrated monitoring and control of maximum 256 of MPS Variable Multi air conditioner systems. Specially, operation status of the individual air conditioner can be particularly checked. Individual or simultaneous operation of the air conditioner, operation mode, wind quantity, user locking and temperature setup are also available. Specially for this system, installation is simple and user's environment is excellent. Central control is available by a simple manipulation. In addition, this system have the self-battery built-in and can stably operate in spite of outside disturbance such as temporary power failure. This system has no need of additional peripheral equipment like UPS (Undisturbed Power System) and AVR to be purchased for stability when composing the existing PC central control system, and has so attractive advantage in installation costs. Using the Deluxe Central control enables the management room to setup lock of each air conditioner and prevent indoor control of the individual air conditioner and restrain the necessary use. In case of releasing the lock, you may control the system by using the wire/wireless remote control at the place where the individual air conditioner is installed. Setup of a weekly schedule is available and detailed schedule of the individual air conditioner can be easily setup through the GUI. Details of schedule setup can be immediately checked with a graph. This system is a product to meet energy saving and convenience at the same time at a place like a school by using this schedule function. Depending on installation environment, location and conditions of use, you can setup groups. With this setup, more efficient operation at the center is available. Setup without requiring other equipment is available by using the GUI and change by the consumer is also available after installation. You can reduce development time to configure special system upon the request by the consumer and conveniently this system by using the touch panel. Where needs from a new customer occur or where purchase of additional air conditioner is done, the Deluxe Central control can be smoothly installed.

149 2. Central Control Major Characteristics Figure 2) Deluxe Central control 1. Individual/Integrated Operation/Monitoring You can identify operation status of the air conditioner, operation mode, wind quantity, wind direction, locking, temperature setting and error, etc by selecting the installed air conditioner through individual selection, group selection or all selection. Individual setup and operation of the detailed functions are available. Therefore, managing with Deluxe Central control installed at the control room at a building where a number of air conditioners are installed, is a convenient way. 2. Group Management Group management for the installed air conditioners is available. Group can be seperated by their nature, location and size of each air conditioner which enables convenient use. In addition, allotment of respective name to the setup group allows further intuitive management. 3. Self-diagnosis Function The air conditioner installed can self-diagnosed its error status and then transmits the result to the central control. Therefore, a rapid countermeasure against failure of the air conditioner allows easy management and increases the usage life of air conditioner. 4. Semi-permanent Life / Convenient Maintenance Since the Deluxe Central control is designed for the semi-permanent use, this system can be used semipermanently after installation, different from the existing PC or a large central control system requiring a continuous management due to the life of peripheral and other PC. 5. Management Costs Down In absence of the Central Control System, the manager controls a number of air conditioners. In addition, even if management was done at the center, there is only function of on/off management at best and thus 2 or 3 building managers were actually required. However, manipulation of all functions can be now done at a control room for the Deluxe Central control and so a manager can easily control all air conditioners. Automatic operation is also allowed without a manager, by using schedule function. 148 MPS(Multi Power System) Variable Multi

150 2. Central Control 6. Convenient GUI / Touch Screen Not requires special education for using the Deluxe Central control, conveniently used only by pressing the buttons on the screen, and its function can be understood with intuitive pictogram. Especially schedule setting is done by simply by dragging, different from the existing system requiring to press the button by more than average 30 times to enter a schedule. 7. Schedule Automatic Operation Management / Energy Saving For the Schedule Automatic Operation, weekly setting is available. Enlisting of the schedule exception processing schedule (national holiday) is done for a year prevents the air conditioner from an unnecessary operation of air conditioner, allowing the system to be controlled at the center so that it can be only used for a necessary case and enabling to obtain excellent energy saving effect. Fixed schedule places like elementary school, middle school, high school and college or university will get its excellent working effect. 8. Power Failure Backup Function / Powerful Stability For the existing Central Control System, additional purchase of expensive UPS equipment in provision for a temporary power failure must be done in the past but for the Deluxe Central control, since the self-power failure compensation battery is built-in, power is automatically converted by maximum 2 hours. Therefore, there is almost no malfunction due to a temporary power failure because stable operation is available. 9. Mobility A wireless radio system may be installed at the Deluxe Central control, it will control the Airconditioners directly while going around the building with the wireless radio system and its self-battery function (100 m where there is no obstacle). 10. Convenient Installation This system can be freely fixed to the wall surface because of its small size, light weight and thin thickness. It can also stood up on the desk by using, its dedicated cradle. It is not subjected to spatial restriction in installation space and location since this system communicates on the basis of the I-GW and the Ethernet. 11. Stable Date Storage/Backup Setup information is saved as it is, even if no power is supplied then also all data is saved in the built-in flash memory. 12. Scalability Scalability of the system is easy in case of additionally purchasing equipment since scalable slot such as USB, Serial (RS-232c), PCMCIA, CF Type is prepared. This system is designed considering sufficient scalability in provision for special request by the customer. 13. Upgrade Additional installation of a new program is available via the CF memory card and the existing program can be upgraded to a new program. Using such upgrade function always enables to construct a modern type of Central Control System Product Data 149
