WARNING • You are requested to use RoHS compliant parts for maintenance or repair. • You are requested to use lead-free solder. F-GAS REGULATION (EC) No 842 / 2006 Do not vent R410A into atmosphere : R410A is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975. REFERENCE NO. SM700842 Important! Please Read Before Starting When Transporting Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers. This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. When Installing For safe installation and trouble-free operation, you must: Carefully read this instruction booklet before beginning. Follow each installation or repair step exactly as shown. Observe all local, state, and national electrical codes. Pay close attention to all warning and caution notices given in this manual. This symbol refers to a hazard or unsafe practice which can WARNING result in severe personal injury or death. CAUTION In a Ceiling or Wall Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support. In a Room Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to walls and floors. In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. In an Area with High Winds Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. In a Snowy Area (for Heat Pump-type Systems) Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents. This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage. If Necessary, Get Help These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions. When Connecting Refrigerant Tubing • Use the flare method for connecting tubing. • Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection. • Check carefully for leaks before starting the test run. In Case of Improper Installation The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document. SPECIAL PRECAUTIONS WARNING When Servicing When Wiring • Turn the power off at the main power box (mains) before opening the unit to check or repair electrical parts and wiring. • Keep your fingers and clothing away from any moving parts. • Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced. ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM. • Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. • Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. • Ground the unit following local electrical codes. • Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard. • Install a protective leakage breaker depending on the installation location (especially a damp or humid location). If a leakage breaker is not installed, electric shock can occur. Others CAUTION • Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. • Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas. 2 Table of Contents Page APPLICABLE MULTI-OUTDOOR UNITS ..................................................................................... 4 1.

FUNCTIONS 7-1. Operation Functions Emergency operation SENSOR DRY Emergency operation is available when the remote controller malfunctions, has been lost, or otherwise cannot be used. During DRY operation, the system adjusts the room temperature and fan speed according to the conditions in the room, in order to maintain a comfortable room environment. SENSOR DRY operation • DRY operation is as shown in the figure below. To operate the system, press the OPERATION button, which is also used as the receiver, below the unit display. Each time this button is pressed, the OPERATION lamp changes color to indicate the type of operation. Select the desired type of operation. COOL HEAT (GREEN) Load STOP (RED) COOL zone (Lamp Off) A zone B zone • The set temperature is 2 °C below the detected room temperature in the case of cooling operation, and 2 °C above the room temperature in the case of heating operation. The flap and fan speed settings are AUTO. Conditions are monitored at all times when the room temperature is below 15 °C. DRY A The compressor operation frequency varies. The indoor fan operates with 1/f fluctuation. AUTO cooling/heating operation Selecting the operation mode DRY B • When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and the room temperature, and automatically switches to Cooling or Heating mode. Room temp. Set temp. COOL Room temp. Set temp. HEAT The compressor operates at a low operating frequency. The indoor fan operates with 1/f fluctuation. Monitor • Monitoring operation takes place when the room temperature is below 15 °C, or more than 3 °C below the set temperature. • When the monitoring range is entered, the compressor stops, and the indoor fan operates with 1/f fluctuation. • As shown by the example in the figure below, with AUTO cooling/heating operation, the mode changes between Heating and Cooling mode according to changes in the relationship between the current room temperature and the set temperature. PAM- control Example Example of operation in AUTO mode with the set room temperature at 23 °C. Room temp. • In order to further improve inverter performance, control is switched between PWM control at low operation speeds, and PAM control at high operation speeds, making the most effective use of power.

Once the freeze condition is detected, the air conditioner will work less than the maximum frequency until it is turned off. 29 8. TROUBLESHOOTING 8-1. Precautions before Performing Inspection or Repair After checking the self-diagnostics monitor, turn the power OFF before starting inspection or repair. High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 310V) even after the power is turned OFF, and some time is required for the charge to dissipate. Be careful not to touch any electrified parts before the controller LED (red) turns OFF. If the outdoor controller is normal, approximately 30 seconds will be required for the charge to dissipate. However, allow at least 5 minutes for the charge to dissipate if there is thought to be any trouble with the outdoor controller. 8-2. Method of Self-Diagnostics < Clock display > Follow the procedure below to perform detailed trouble diagnostics. Test run mode Self-diagnostics mode NOTE 1: If the operation lamp blinks every 0.5 seconds immediately when the power is turned ON, there is an external ROM (OTP data) failure on the indoor circuit board, or a ROM socket insertion problem, or the ROM has not been installed. 2: The failure mode is stored in memory even when the power is not ON. Follow the procedure below to perform diagnostics. PROCEDURE ON/OFF operation button After turning on power to the air conditioner, use the remote controller and follow the steps below to execute self-diagnostics. Step 1: Press and hold the remote controller QUIET button and 1 HR TIMER button. Then, press and hold the ACL (reset) button with a pointed object such as the tip of a pen. After 5 seconds, release ACL button first, then release QUIET and 1 HR TIMER buttons, "oP-1" (test run) appears, blinking in the remote controller clock display area. Step 2: Next, press the 1 HR TIMER button once to change the display from "oP-1" to "oP-3" (self-diagnostics). (The display continues to blink.) Step 3: Finally press the ON/OFF button to engage self-diagnostics mode. • The self-diagnostics function utilizes the 3 indicator lamps on the main unit, in combinations of ON lamps, blinking lamps, and OFF lamps, to report the existence of sensor trouble or a protective operation. (The lamps blink or remain ON for 5 seconds, then turn OFF for 2 seconds.) Self-diagnostics is completed when the buzzer sounds 3 short beeps. • A maximum of 3 self-diagnostics reports are displayed, for 5 seconds each, beginning with the most recent report. Following this display the lamps turn OFF. In order to view the self-diagnostics results again, press the ON/OFF button again. • The 3 lamps remain OFF if no trouble has occurred.After self-diagnostics is completed, be sure to press the ACL (reset) button to return to normal mode. The air conditioner will not operate if this is not done. 30 1HR.

Check the indoor unit. Blown Is the fuse blown? Normal Replace the circuit board or the fuse. Replace the controller. 8-3. Checking the Indoor and Outdoor Units (1) Checking the indoor unit No. Control 1 Check items (unit operation) • The rated voltage must be present between inter-unit wirings 1 and 2. • Connect a 5 k ohm resistor between inter-unit wirings 2 and 3. When the voltage at both ends is measured, approximately 12 to 15V DC must be output and the multimeter pointer must bounce once every 8 seconds. Or instead of measuring the voltage, you can insert an LED jig and check that the LED flickers once every 8 seconds. Use the remote controller to operate the unit in "TEST run" mode. To determine whether the mode is currently in "TEST run" mode, check the 4 indicator lamps on the unit. If all 4 are blinking, the current mode is "TEST run." If there are no problems with the above, then check the outdoor unit. For the "Test run" procedure, refer to 5. "HOW TO TEST RUN THE AIR CONDITIONER" on Appendix C. (2) Checking the outdoor unit No. Control Check items (unit operation) 1 Apply the rated voltage between outdoor unit terminals L and N. • The control panel LED (red) must illuminate. 2 Short-circuit the outdoor unit COM terminal to the T-RUN terminal. • The compressor, fan motor, and 4-way valve must all turn on. If there are no problems with the above, then check the indoor unit. TEST/T-RUN terminals Using the TEST/T-RUN terminals T-RUN : Test run (compressor and fan motor turn ON).

Refer to the previous pages when performing system self-diagnostics. So that the check can be made quickly, indicators blink at first communication after power ON. Before performing the above checks, perform “TEST run” operation, and check that the rated voltage is output to terminals L and N on the outdoor unit. If it is not output, there is a failure related to the indoor unit power. 32 8-4. Trouble Diagnosis of Fan Motor 8-4-1. Indoor Fan Motor This indoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor. To perform diagnosis, operate the unit in cooling mode with indoor fan speed "High". Next, make sure that the indoor unit receive the signals from the remote controller when the ON/OFF operation button is pressed. Important: (A) Turn OFF the power before connecting or disconnecting the motor connectors. (B) When performing voltage measurement at the indoor controller connector for (3) in the table below, the DC motor will trip and voltage output will stop approximately 1 minute after operation is started. For this reason, to measure the voltage again, turn OFF the unit once using the remote controller, and then start the air conditioner again. [Trouble symptom 1] The fan does not stop when the unit stops. Indoor unit controller trouble. [Trouble symptom 2] The fan motor does not rotate when the unit is operating. (Diagnostic procedure) * Disconnect the motor connectors and measure the voltage at the DC motor connectors on the indoor unit controller (3 locations). Measurement location (1) Vm-Gnd: Between pin 1 and pin 3 (2) Vcc-Gnd: Between pin 4 and pin 3 (3) Vs-Gnd: Between pin 5 and pin 3 Normal value DC 230V or more DC 14V or more Fluctuation between DC 1.7 to 6.1V (Diagnostic results) All of the above measured values are normal. Fan motor trouble (Replace the motor.) Any one of the above measured values is not normal. Indoor unit controller trouble (Replace the controller .) (Reference) DC motor connector pin arrangement Pin 1: Vm (red) Pin 2: Not used Pin 3: Gnd (black) Pin 4: Vcc (white) Pin 5: Vs (yellow) Pin 6: PG (blue) [Trouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the indoor unit operates. (There is trouble in the system that provides feedback of motor rotation speed from the motor to the indoor unit controller.) [Trouble symptom 4] Fan motor rotation speed does not change during indoor unit operation. [Trouble symptom 5] Fan motor rotation speed varies excessively during indoor unit operation. (Remedy for symptom 3 to 5) It is not possible to identify whether the trouble is indoor unit controller trouble or motor trouble. Therefore, first replace the indoor unit controller, then (if necessary) replace the DC motor. 33 8-5. Noise Malfunction and Electromagnetic Interference An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices. A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur. Please pay attention to the points listed below. (1) Noise malfunction This refers to the application of high-frequency noise to the signal wires, resulting in abnormal signal pulses and malfunction. Locations most susceptible to noise 1. Locations near broadcast stations where there are strong electromagnetic waves 2. Locations near amateur radio (short wave) stations 3. Locations near electronic sewing machines and arc-welding machines Trouble Either of the following trouble may occur. 1. The unit may stop suddenly during operation. 2. Indicator lamps may flicker. Correction (The fundamental concept is to make the system less susceptible to noise.) - Insulate for noise or distance from the noise source. 1. Use shielded wires. 2. Move unit away from the noise source. (2) Electromagnetic interference This refers to noise generated by high-speed switching of the microcomputer and compressor. This noise radiates through space and returns to the electric wiring, affecting any wireless devices (televisions, radios, etc.) located nearby. Locations most susceptible to noise 1. A television or radio is located near the A/C and A/C wiring. 2. The antenna cable for a television or radio is located close to the A/C and A/C wiring. 3. Locations where television and radio signals are weak. Trouble Correction 1. Noise appears in the television picture, 1. Select a separate power source. or the picture is distorted. 2. Keep the A/C and A/C wiring at least 1 meter 2. Static occurs in the radio sound. away from wireless devices and antenna cables. 3. Change the wireless device’s antenna to a highsensitivity antenna. 4. Change the antenna cable to a BS coaxial cable. 5. Use a noise filter (for the wireless device). 6. Use a signal booster. 34 APPENDIX A INSTRUCTION MANUAL SAP-KMRV76EH SAP-KMRV96EH SAP-KMRV126EH (OI-852-6-4181-008-00-2) A-1 00_SAP-KMRV76EH_Cover.fm Page 2 Friday, August 21, 2009 1:29 PM SAP-KMRV76EH SAP-KMRV96EH SAP-KMRV126EH COOL/DRY/HEAT Model INSTRUCTION MANUAL Inverter-Controlled Split System Air Conditioner MANUAL DE INSTRUCCIONES This air conditioner uses the new refrigerant R410A.

Use sunshades, blinds or curtains. If the walls and ceiling of the room are warmed by the sun, it will take longer to cool the room. Do • Always try to keep the air filter clean. (Refer to “CARE AND CLEANING”.) A clogged filter will impair the performance of the unit. • To prevent conditioned air from escaping, keep windows, doors and any other openings closed. ADJUSTING THE AIRFLOW DIRECTION 1. Horizontal The horizontal airflow can be adjusted by moving the vertical vanes with your hands to the left or right. OI-003-13-EG 2. Vertical The vertical airflow can be adjusted by moving the flap with the remote control unit. Do not move the flap with your hands. Confirm that the remote control unit has been turned on. Use the FLAP button to set either the sweep function or one of the six airflow direction settings. A. Sweep function The flap starts moving up and down to deliver air over the sweep range. B. Setting the airflow manually SWEEP Referring to the above illustration, use the COOL FLAP button to set the DRY airflow direction within the range used during the heating, cooling, or dehumidifying operation. SWEEP HEAT FAN C. Auto flap function The flap is set to the recommended position. NOTE • The flap automatically closes when the unit is off. • During the heating operation, the fan speed will be very low and the flap will be in the horizontal position (position ) until the air being blown out of the unit begins to warm. Once the air warms up, the flap position and fan speed change to the settings specified with the remote control. CAUTION • Use the FLAP button on the remote control to adjust the position of the flap. If you move the flap by hand, the flap position according to the remote control and the actual flap position may no longer match. If this should happen, shut off the unit, wait for the flap to close, and then turn on the unit again; the flap position will now be normal again. • Do not have the flap pointed down during cooling operation. Condensation may begin to form around the air vent and drip down. 13 01_SAP-KRV186EH_EN.fm Page 14 Wednesday, February 13, 2008 1:12 PM OPERATION WITHOUT THE REMOTE CONTROL UNIT Anti-Mold Filter The anti-mold filter behind the front panel should be checked and cleaned at least once every two weeks.

As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. When Installing… …In a Ceiling or Wall Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support. …In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors. …In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. For safe installation and trouble-free operation, you must: G Carefully read this instruction booklet before beginning. G Follow each installation or repair step exactly as shown. G Observe all local, state, and national electrical codes. G Pay close attention to all warning and caution notices given in this manual. This symbol refers to a hazard or unsafe practice which can WARNING result in severe personal injury or death. This symbol refers to a hazard or unsafe practice which can CAUTION result in personal injury or product or property damage. When Connecting Refrigerant Tubing • Do not add any refrigerant, air, or substance into the refrigeration circuit other than the designated refrigerant (R410A). Adding anything other than the specified refrigerant may cause the pressure to rise excessively in the refrigeration circuit, rupturing the circuit and causing injury or damage. • Use all-new tubing and flare nuts to make the tubing connections. Using any previous parts (from R22based systems) may result in damage to the equipment, and may lead to the refrigeration circuit rupturing, causing a serious accident. • Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection. • Check carefully for leaks before starting the test run. If Necessary, Get Help These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions. In Case of Improper Installation The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document. SPECIAL PRECAUTIONS WARNING • • • • • When Servicing When Wiring • Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring. • Keep your fingers and clothing away from any moving parts. • Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced. ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM. Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. Ground the unit following local electrical codes. Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard. Install a protective leakage breaker/fuse link depending on the installation location (especially a damp or humid location). If a leakage breaker/fuse link is not installed, electric shock can occur. CAUTION Others • Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. • Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.
