NOTE:
• Throughly study the following installation locations: 1. 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.

Piping and Drainage of Indoor Unit
1. Preparation of pipings
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 the measured distance. • Cut the cable 1.5m longer than the length of the pipe.

2) Remove burrs. • Remove burrs from cut edges of pipes. • Turn the pipe end toward down to avoid the metal powder entering the pipe.

Reamer

CAUTION: If burrs are not removed, they may cause a gas leakage.

Point down

3) Flaring the pipes. • Insert the flare nuts, mounted on the connection ports of both indoor and outdoor unit, onto the copper pipes. Some refrgerant gas may leak, when the flare nuts are removed from the indoor unit, as some gas is charged to prevent the inside of the pipe from rusting. • Fit the copper pipe end into the Bar of flare tool about 0~0.5mm higher. (See illustration) • Flare the pipe ends. 4) Tape the flaring portion to protect it from the dust or damages.

Deluxe Central Control
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.

Major Characteristics

Figure 2) Deluxe Central control

1. Individual/Integrated Operation/Monitoring
s 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
s 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
s 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
s 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
s 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.

114 Multi type Air Conditioner

Control Devices and Function 6. Convenient GUI / Touch Screen
s 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
s 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
s 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
s 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

Troubleshooting Guide

Cycle Troubleshooting Guide
Trouble analysis
1. Check temperature difference between intake and discharge air, and operating current. Temp. difference Current : approx. 0°C : less than 80% of rated current All amount of refrigerant leaked out. Check refrigeration cycle.

Temp. Difference Temp. difference Current Operating Current Temp. difference Current : less than 8°C : near the rated current Excessive amount of refrigerant : approx. 8°C : less than 80% of rated current Refrigerant leakage Clog of refrigeration cycle Defective compressor

Temp. difference

: over 8°C

Normal

Notice: Temperature difference between intake and discharge air depends on room air humidity. When the room air humidity is relatively higher, temperature difference is smaller. When the room air humidity is relatively lower temperature difference is larger. 2. Check temperature and pressure of refrigeration cycle. Suction pressure (Compared with the normal value) Temperature (Compared with the normal value) High Higher Normal Excessive amount of refrigerant Insufficient amount of refrigerant(Leakage) Clogging High pressure does not quickly rise at the beginning of operation. Current is low.

Cause of Trouble Defective compressor

Description Current is low.

Lower

Higher

Notice: 1. The suction pressure is usually 4.5~6.0 kg/cm G at normal condition. 2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with putty.

❇ Refer to electronic contorol device drawing & schematic diagram.

Trouble 1

The Product doesn’t operate at all.

Turn off the main power and wait until LED on outdoor PCB is off.

Turn on the main power again.

Does "Beeping" sound is made from the indoor unit? NO Check the voltage of power(AC220V/AC240V, 50Hz). • The voltage of main power. • The voltage applied to the unit. • The connecting method of Indoor/Outdoor connecting cable (each color) • The P.W.B. Ass'y (Fuse, Noise Filter, Power Transformer, IC01D, IC02D, etc.) YES • Primarily, the operating condition of Micom is O.K.

• Check CN-DISP1

The operation check of the P.C.B. Ass'y Procedure 1) The input voltage of power transformer. 2) The output voltage of power transformer. 3) IC01D(7812) 4) IC02D(7805) 5) IC01A(KIA7036) Specification 1) AC230V ± 30V : Check the rated voltage 2) 14V ± 3V 3) DC12V 4) DC5V 5) The voltage of micom pin 29 : DC4.5V↑ Remedy 1) Replace power transfomer. 2) Replace power transfomer. 3) Replace IC01D. 4) Replace IC02D. 5) Replace IC01A.

Troubleshooting Guide

Trouble 2

Product doesn't operate with the remote controller.
Turn on main power.

While the compressor has been stopped, the compressor does not operate owing to the delaying function for 3 minutes after stopped.

When the compressor stopped Indoor Fan is driven by a low speed. At this point the wind speed is not controlled by the remote controller. (When operated in the Sleeping Mode, the wind speed is set to the low speed as force.)

Caused by the remote controller.

Caused by other parts except the remote controller

When the mark ( ) is displayed in LCD screen, replace battery.

Check the contact of CN-DISP 1 connector

When the detect switch (double key) inside the remote controller door is fault, it is impossible to operate temperature regulating(v / w) and wind speed selecting.

Check DISP PWB Ass'y -Voltage between CN1 ➀ - ➆ : DC +5V

Check the Display PWB Ass'y

• Check receiver ass'y

Service Manual 169

Troubleshooting Guide

Trouble 3

The Compressor/Outdoor Fan don't operate

Turn on the main power.

Operate Cooling Mode by setting the disired temperature of the remote controller is less than one of the Indoor temperature by 1°C at least.

When in air circulation mode, compressor/outdoor fan is stopped.

Check the sensor for Indoor temperature is attatched as close as to be effected by the themperature of Heat Exchange (EVA.)

Stop operation and wait for 3 minutes, then connect the manifold gauge to the service port of the gas side valve. - Connect the hose of the gauge with the push pin to the service port. 4. Air purging of the charge hose. - Open the Low-handle valve on the gauge slightly to air purge from the hose. 5. Set the liquid side valve to the closed position. • Be sure to short pressure S/W. otherwise Low pressure S/W detect low pressure skete and stops the compressor. 6. Operate the air conditioner at the cooling cycle and stop it when the gauge indicates 1kg/cm g.

• Procedure
1. Connect the gauge to the charging cylinder. - Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder. - If you are using a gas cylinder, also use a scale and reverse the cylinder so that the system can be charged with liquid. 2. Purge the air from the charge hose. - Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air. (Be careful of the liquid refrigerant). The procedure is the same if using a gas cylinder. 3. Open the low handle on the gauge and charge the system with liquid refrigerant. - If the system can not be charged with the specified amount of refrigerant, it can be charged with a little at a time (approximately 150g each time) while operating the air conditioner in the cooling cycle; however, one time is not sufficient, wait approximately 1 minute and then repeat the procedure(pumping down-pin). 4. Immediately disconnect the charge hose from the gas side valve's service port. This is different from previous procedures. Because you are charging with liquid refrigerant from the gas side, absolutely do not attempt to charge with larger amounts of liquid refrigerant while operating the air conditioner. - Stopping partway will allow the gas to be discharged. - If the system has been charged with liquid refrigerant while operating the air conditioner turn off the air conditioner before disconnecting the hose. 5. Mount the valve stem nuts and the service port nut. - Use torque wrench to tighten the service port nut to a torque of 1.8 kg.m.(4.2kg.m/5.5kg.m.) - Be sure to check for gas leakage.
