Safety Precautions

Use power cables of sufficient current carrying capacity and rating.

• Cables that are too small may leak, generate heat, and cause a fire.

Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigeration system.

• There is risk of damage or loss of property.

Keep the unit away from children. The heat exchanger is very sharp.

• It can cause the injury, such as cutting the finger. Also the damaged fin may result in degradation of capacity.

When installting the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.

•

The inverter equipment, private power generator, high-frequency medical equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

Do not install the product where it is exposed to sea wind (salt spray) directly.

• It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

Service Manual 9

Safety Precautions

■ Operation

Do not use the air conditioner in special environments.

• Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the air conditioner or damage its parts.

Do not block the inlet or outlet.

• It may cause failure of appliance or accident.

Make the connections securely so that the outside force of the cablemay not be applied to the terminals.

• Inadequate connection and fastening may generate heat and cause a fire.

Be sure the installation area does not deteriorate with age.

• If the base collapses, the air conditioner could fall with it, causing property damage, product failure, or personal injury.

Install and insulate the drain hose to ensure that water is drained away properly based on the installation manual.

• A bad connection may cause water leakage.

Be very careful about product transportation.

• Only one person should not carry the product if it weighs more than 20 kg.

• Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.

• Do not touch the heat exchanger fins. Doing so may cut your fingers.

• When transporting the Outdoor Unit, suspending it at the specified positions on the unit base. Also support the Outdoor Unit at four points so that it cannot slip sideways.

Safety Precautions

Safely dispose of the packing materials.

•

Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

•

Tear apart and throw away plastic packaging bags so that children may not play with them. If children play with a plastic bag which was not torn apart, they face the risk of suffocation.

Turn on the power at least 12 hours before starting operation.(In case of outdoor temperature 5°C below)

• Starting operation immediately after turning on the main power switch can result in severe damage to internal parts. Keep the power switch turned on during the operational season.

Do not touch any of the refrigerant piping during and after operation.

• It can cause a burn or frostbite.

Do not operate the air conditioner with the panels or guards removed.

• Rotating, hot, or high-voltage parts can cause injuries.

Do not directly turn off the main power switch after stopping operation.

• Wait at least 5 minutes before turning off the main power switch. Otherwise it may result in water leakage or other problems.

Auto-addressing should be done in condition of connecting the power of all indoor and outdoour units. Auto-addressing should also be done in case of changing the Indoor Unit board(PCB).

Use a firm stool or ladder when cleaning or maintaining the air conditioner.

• Be careful and avoid personal injury.

Do not insert hands or other objects through the air inlet or outlet while the air conditioner is plugged in.

• There are sharp and moving parts that could cause personal injury.

1. Cut the pipes and the cable.

• Use the accessory piping kit or the pipes purchased locally.

• Measure the distance between the indoor and the outdoor unit.

• Cut the pipes a little longer than measured distance.

•

Cut the cable 1.5m longer than the pipe length.

2. Burrs removal

• Completely remove all burrs from the cut cross section of pipe/tube.

•

Put the end of the copper tube/pipe to downward direction as you remov e b urrs in order to a void to let burrs drop in the tubing.

3. Putting nut on

• Remove flare nuts attached to indoor and outdoor units, than put them on pipe/tube having completed burr removal. (Not possible to put them on after flaring work)

4. Flaring work

•

Carry out flaring work using dedicated flaring tool

for R-410A as shown below.

Firmly hold copper tube in a bar(or die) as indicated dimension in the table above.

5. Check

• Compare the flared work with figure below.

• If flare is noted to be defective, cut off the flared

section and do flaring work again.

2.1.1 Summary

Deluxe Central control is a product available for individual and integrated monitoring and control of maximum 256 of TPS Inverter 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.

Control Devices and Function

Major Characteristics

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.

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 oper-

ation 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 fail-

ure 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 installa-

tion 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 scala-

bility 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.
