2 Important! Please Read Before Starting 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. 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. ARNING CAUTION SPECIAL PRECAUTIONS ARNING hen iring This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death. 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. 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. ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO IRE 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. hen 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. hen Installing In a Ceiling or all 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 inds 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. hen 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. hen Servicing 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. 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.

34 7. FUNCTIONS 7-. Explanation of Functions NOTE The numerical values such as temperature, frequency, time and current in parentheses are an example of SAP-CMRVEH and the values are different from the other models. Control/conditions Unit operation Explanation INITIAL Breaker is ON. Power is supplied to the indoor and outdoor unit control circuits, however the unit remains stopped. Positioning of the outdoor unit electric expansion valve is performed. The ON/OFF operation button on the remote controller is pressed. If automatic operation mode has been selected with the remote controller, operation begins in HEAT, SENSOR DRY, or COOL mode depending on the room temperature and outdoor temperature at the time operation starts. This applies in the case of automatic HEAT/COOL operation. Depending on the operational mode, refer to the HEAT, SENSOR DRY, or COOL item. HEAT The ON/OFF operation button on the remote controller is pressed. Operation lamp illuminates. Indoor fan is stopped to prevent cold air from being emitted. Outdoor unit begins operating after forced-stop is canceled. The unit is forced to stop for minutes after the power is turned ON, or minutes after the compressor stops, in order to protect the compressor. The frequency is increased at the rate of Hz every 0. seconds. hen the indoor coil temperature rises, the compressor starts, the outdoor fan starts, and the indoor fan changes from "LL" to the set fan speed. Depending on the relationship between the remote controller temperature setting and the room temperature, the compressor may stop temporarily (in other words, the thermostat may turn OFF). hen the frequency reaches Hz,frequency increases are stopped for a period of seconds. (Refor to Table "Freguency control".) This is in order to stabilize the return of oil to the compressor. The frequency then increases. If the indoor and outdoor temperatures are high, the current peak cut-off activates, stopping any increases in frequency. The room temperature has reached the desired temperature. The indoor temperature and the remote controller temperature setting are approximately equal. Operating frequency is stabilized in order to maintain a comfortable environment. The thermostat turns OFF. The indoor fan is stopped. The outdoor unit stops. (It does not stop if the thermostat for another indoor unit is ON.) Approximately 0 seconds after the thermostat turns OFF, the indoor fan is stopped. The indoor and outdoor temperatures are high. In order to protect the compressor, the outdoor unit will not operate for minutes after the thermostat turns OFF, even if the room temperature drops below the desired temperature. The outdoor unit starts automatically after minutes. During these minutes, a low-pressure pressure balance is achieved, allowing the compressor to start more easily. The frequency is not increased, even if there is a difference between the room temperature and the desired temperature. In some cases, the frequency may be decreased. The amount of heat pump exceeds the amount of heat radiation from the room. Therefore, there is no need to further increase the compressor capacity, and the frequency is stabilized or lowered. The thermostat turns ON. The indoor unit is stopped. The unit operated before, and the temperature of the indoor heat exchanger is relatively warm. Therefore,the fan speed may start at the set fan speed at the same time that the thermostat turns ON.

35 Control/conditions Unit operation Explanation HEAT hen defrost operation begins, frost has formed on the outdoor unit (when the ambient air temperature is low). Non-stop defrost Indoor fan : Stopped Outdoor fan : Stopped Compressor : 80 Hz Solenoid valve (for hot gas bypass): ON -way valve : Remains ON Operation lamp : Red and orange ON alternately Defrost operation begins based on outdoor temperature conditions. Non-stop defrost (Refer to Fig. ). After HEAT operation begins, the temperature of the outdoor heat exchanger is at or below the L line for minutes. (If outdoor air temperature is less than C, the time is 8 minutes). After HEAT operation begins, the temperature of the outdoor heat exchanger is at or below the L line for 0 minutes. The -way valve remains ON during defrost. The outdoor fan stops and the solenoid valve turns ON, allowing the refrigerant to bypass the indoor unit. The operating frequency during defrost is 80 Hz. (Frequency is lowered if the current peak cut-off function is activated.) The maximum length of a single defrost operation is minutes. For the outdoor heat exchanger temperature conditions for ending defrost, refer to Table. Defrost release Indoor fan turns ON. After 0 seconds, the solenoid valve (for hot gas bypass) turns OFF. hen the cold air feel has disappeared, the indoor fan starts and gradually increases speed until it reaches the set speed. STOP [Clean defrost] Defrost is performed when the outdoor unit is stopped, and the temperature of the outdoor unit coil is at or below the L line. (Refer to Fig..) All indicator lamps turn OFF. The indoor and outdoor units stop. Operation is restarted within hours (only when AUTO mode is selected with the remote controller). Starts operating in the same operating mode (HEAT) and with the same temperature settings as before operation was stopped. ithin hours after operation was stopped, it is assumed that there has been no significant change in the indoor and outdoor temperatures, and the previous conditions (HEAT) are stored. Operation starts after hours or more have passed. New operation begins based on the temperature conditions at the time the ON/OFF button is pressed.

36 Control/conditions Unit operation Explanation COOL The ON/OFF operation button on the remote controller is pressed. The operation lamp illuminates. The indoor fan operates at the set fan speed. The outdoor unit stops. The outdoor unit does not operate for minutes even after the breaker is turned ON. The outdoor unit starts. The frequency is increased at the rate of 0. Hz every seconds. (Compressor and the outdoor fan start.) hen the frequency reaches Hz, frequency increases are stopped for a period of seconds. (Refer to Table.) This is in order to stabilize the return of oil to the compressor. The frequency then increases. If the indoor and outdoor temperatures are high, the current peak cut-off activates, stopping any increases in frequency. The room temperature has reached the desired temperature. The indoor temperature and the desired temperature are approximately equal. Operating frequency is stabilized in order to maintain a comfortable environment. The thermostat turns OFF. The outdoor unit stops. (It does not stop if the thermostart for another indoor unit is ON.) The thermostat turns ON again. After the thermostat turns ON again, the outdoor unit will not operate for minutes, even if the room temperature increases above the desired temperature. After minutes, the outdoor unit begins operating automatically. During these minutes, a pressure balance is achieved, allowing the compressor to start more easily. Freeze prevention hen the temperature of the indoor heat exchanger drops to approximately C or below, the compressor turns OFF, the outdoor fan turns OFF, and the indoor fan continues operating with no changes. In order to protect against freezing, the compressor stops temporarily, until the temperature of the indoor heat exchanger has risen. Approximately minutes later, if the temperature of the indoor heat exchanger is adove 8 C, the system returns to its original conditions. Stop All indicator lamps turn OFF. The indoor and outdoor units stop. Operation is restarted within hours (only when AUTO mode is selected with the remote controller). Starts operating in the same operating mode (COOL) and with the same temperature settings as before operation was stopped. ithin hours after operation was stopped, it is assumed that there has been no significant change in the indoor and outdoor temperatures, and the previous conditions (COOL) are stored. Operation starts after hours or more have passed. New operating mode is determined based on the temperature conditions at the time the ON/OFF operation button is pressed.

39 7--. Current Control The operating current may rise as a result of causes including increasing heating or cooling loads or decreases in power voltage. In these cases, the operating frequency is automatically reduced, or operation is stopped, in order to control the operating current so that it is (0 A) or less. As a result: Power breakers and fuses will not be tripped. Operation can continue during this period with somewhat reduced heating or cooling capacity. Operation at normal capacity is restored when the cause of the current rise is eliminated.

41 8. TROUBLESHOOTING 8-. Precautions before Performing Inspection or Repair Both the indoor unit and outdoor unit include electronic control circuits. Be sure to pay attention to the following before inspecting or repairing the outdoorside electronic circuits. High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC V) 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 control circuit board Power Lamp (red) turns OFF. If the outdoor control circuit board is normal, approximately 80 seconds will be required for the charge to dissipate. However, allow at least 0 minutes for the charge to dissipate if it is thought there might be trouble with the outdoor control circuit board. For example, if the outdoor control circuit board fuse has blown, approximately 0 minutes will be required to discharge the high-capacity electrolytic capacitors.

Check that the electric expansion valve is not blocked. Chesck as described on the preceding page. 6

47 8-. Trouble Diagnosis of Fan Motor This outdoor 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, follow the instructions in "8--. Checking the Outdoor Unit" and set the outdoor unit to Test Run mode (compressor ON, outdoor fan motor ON). Important: (A) Turn OFF the power before connecting or disconnecting the motor connectors. (B) hen performing voltage measurement at the outdoor controller connector for () in the table below, the DC motor will trip and voltage output will stop approximately 0 seconds after operation is started. For this reason, to measure the voltage again, first turn OFF the outdoor unit power, then follow the instructions in "Checking the Outdoor Unit" and again set the unit to Test Run mode. [Trouble symptom ] The fan does not stop when the outdoor unit stops. Outdoor unit controller trouble [Trouble symptom ] The fan motor does not rotate when the outdoor unit is operating. (Diagnostic procedure) * Disconnect the motor connectors and measure the voltage at the DC motor connectors on the outdoor unit controller ( locations). Measurement location () Vs-Gnd: Between pin and pin () Vcc-Gnd: Between pin and pin () Vsp-Gnd: Between pin 7 and pin Normal value DC 0V or more DC V or more After fluctuating times between DC.0 to.v ( sec. ON) and DC 0 V ( sec. OFF), the DC motor trips. (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. Outdoor unit controller trouble (Replace the controller.)

Fan motor rotation speed varies excessively during outdoor unit operation. (Remedy for symptom to ) It is not possible to identify whether the trouble is outdoor unit controller trouble or motor trouble. Therefore, first replace the outdoor unit controller, then (if necessary) replace the DC motor. 7

48 9. REFRIGERANT R0A: SPECIAL PRECAUTIONS HEN SERVICING UNIT 9-. Characteristics of New Refrigerant R0A 9--. hat is New Refrigerant R0A? R0A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R Components (mixing proportions) HFC (0%) / HFC (0%) 9--. Characteristics Less toxic, more chemically stable refrigerant The composition of refrigerant R0A changes whether it is in a gaseous phase or liquid phase. Thus, when there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant. Therefore, do not add new refrigerant. Instead, recover the remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase). hen refrigerant R0A is used, the composition will differ depending on whether it is in gaseous or liquid phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state. Thus, always charge the refrigerant while it is in liquid phase. CAUTION Ether-type oil is used for compressor oil for R0A-type units, which is different from the mineral oil used for R. Thus more attention to moisture prevention and faster replacement work compared with conventional models are required. 9-. Checklist before Servicing Use a clutch-type flare tool for R0A or the conventional flare tool. Note that sizes of the resultant flares differ between these two tools. here a conventional flare tool is used, make sure to observe A Specification (amount of extrusion) by using the flare spacer. Diameter of tube D Dia.6. mm (/") Dia.9. mm (/8") Dia..7 mm (/") Dia.. mm (/8") Specification A Flare tool for R0A Conventional flare tool (for R) 0 to 0. mm. mm Size of flare D D Spacer A A Flare tool for R0A Conventional flare tool (R) 8

49 Tubing precautions Refrigerant R0A is more easily affected by dust or moisture compared with R, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation. Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners with R0A are subject to higher pressure than those using R and R07C. No addition of compressor oil for R0A No additional charge of compressor oil is permitted. No use of refrigerant other than R0A Never use a refrigerant other than R0A. If refrigerant R0A is exposed to fire Through welding, etc., toxic gas may be released when R0A refrigerant is exposed to fire. Therefore, be sure to provide ample ventilation during installation work. Caution in case of R0A leak Check for possible leak points with the special leak detector for R0A. If a leak occurs inside the room, immediately provide thorough ventilation. 9

50 9-. Tools Specifically for R0A For servicing, use the following tools for R0A Tool Distinction Tools specifically for R0A Tools which can be commonly used for R, R07C, and R0A Tool Name Gauge manifold Charging hose Gas leak detector Refrigerant cylinder Charging cylinder Refrigerant recovery unit Vacuum pump with anti-reverse flow (*) (Solenoid valve-installed type, which prevents oil from flowing back into the unit when the power is off, is recommended.) Vacuum pump (*)...can be used if the following adapter is attached. Vacuum pump adapter (reverse-flow prevention adapter) (*). (Solenoid valve-installed adapter attached to a conventional vacuum pump.)

However, all four indoor units must not be operated concurrently. Otherwise, the air conditioner may not run properly. Up to three indoor units may be operated concurrently. The table lists the wall-mounted type of indoor units as representative models. For details on the connection of indoor units other than the wall-mounted type, refer to the catalog.

112 Save this Combination Table! Please be sure to hand over this sheet to the user. -Room Outdoor Unit Combination Table SAP-CMRVEH <Combinations of Connectable Indoor Units> The combinations of the indoor units listed in Table on the next page are combinations solely of those units which can be operated concurrently. In addition to the combinations listed in the table, other combinations of indoor units are possible provided that the following conditions are satisfied. Conditions:. At least two or more indoor units must be connected to the multi outdoor unit. It is not acceptable for only one indoor unit to be connected.. The total rated cooling capacity of the indoor units to be connected must be no more than 00% of the rated cooling capacity of the outdoor unit. CAUTION In this case, all the indoor units installed must not be operated concurrently under any circumstances. Otherwise, the air conditioner may not run properly and trouble may occur. Example: hen four indoor units are connected If the following holds true Rated cooling capacity of SAP-CMRVEH outdoor unit: C=8 (k) Rated cooling capacity of indoor units: K, K,... (k) Then: C x (00%) K + K x It is therefore possible to connect four units with respective capacities of However, since this combination is not found in the -room operation column of Table, operating all these units concurrently may result in trouble. At a time like this, shut down at least one of the four indoor units to match one of the combinations found in the -room operation column of Table. NOTE Be sure to operate the air conditioning system only when or more indoor units have been installed. If operated with only a single unit installed, the returning fluid to the compressor may cause a malfunction. Pub. OI SANYO 006
