26 7. INST ALLA TION INSTRUCTIONS 7-1. Installation Site Selection 7-1-1. Indoor Unit AVOID: ● direct sunlight. ● nearby heat sources that may affect performance of the unit. ● areas where leakage of flammable gas may be expected. ● places where large amounts of oil mist exist.
27 7-1-2. Outdoor Unit AVOID: ● heat sources, exhaust fans, etc. (Fig. 4) ● damp, humid or uneven locations. DO: ● choose a place as cool as possible. ● choose a place that is well ventilated. ● allow enough room around the unit for air intake/ exhaust and possible maintenance.
28 7-2. Recommended Wire Length and Diameter Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these regulations when carrying out the installation.
29 7-3-1. Mounting on a W all Before mounting the remote control unit, press the ON/OFF operation button at the mounting location to make sure that the air conditioner oper- ates from that location. The indoor unit should make a beeping sound to indicate that it has received the signal.
30 7-4. How to T est Run the Air Conditioner After turning on power to the air conditioner, use the remote controller and follow the steps below to conduct the test run. (1) Set the remote controller in Test Run mode. (Fig. 8a) a) Press and hold the QUIET button.
31 7-5. Remove the Grille to Install the Indoor Unit Basically, these models can be installed and wired without removing the grille. If access to any internal part is needed, follow the steps as given below. How to remove the grille (1) Grasp both ends of the air intake grille, and remove it by opening towards the front and pulling towards you.
32 8. MAINTENANCE 8-1. Address Setting of the Remote Control Unit The address can be set in order to prevent interfer- ence between remote controllers when two Sanyo indoor units are installed near each other. The address is normally set to “A.” To set a different address, it is necessary to change the address on the second remote controller.
33 8-2. Disconnecting and Connecting Positive Connector for Outdoor Unit One of the two types of connectors illustrated at left is used. Their basic structure is the same for each. How to Disconnect Hold the resin connector cover, and pull the connector off.
34 9. FUNCTIONS 9-1. Operation Functions ■ Emergency operation ■ SENSOR DR Y ■ AUT O cooling/heating operation ● Selecting the operation mode 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.
35 ■ HIGH POWER This function acts to raise the power but keeps the AC system in the same operating mode. This function is set with the HIGH POWER button on the remote controller . (It can be set regardless of the temperature and fan speed settings.
36 ■ Overload prevention during heating 9-2. Protective Functions During HEA T operation, the temperature of the indoor heat exchanger is used to control the frequency and lessen the load on the compressor before the protective device is activated.
37 Heating operation Frost sensing Reverse-cycle defrosting operation Defrosting Sequence Releasing of defrosting ● ● • • Outdoor fan ON 4-way valve ON ● ● Outdoor heating exchanger temp. is over 14 ° C. Defrosting operation lasts 12 minutes (maximum).
38 10. TROUBLESHOOTING ■ Precautions before performing inspection or repair NOTE Executing self-diagnostics ● 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).
39 Self-diagnostics Lamps Indication on indoor unit .... OFF Timer Operation Code Diagnostics item Diagnostics contents S01 Room temperature sensor failure 1 Sensor open circuit or short circuit 2 Con.
40 ■ If self-diagnostics function fails to operate <Checking the indoor and outdoor units> ■ Checking the indoor unit ■ Checking the outdoor unit ■ Checking serial communications Check the indoor unit. Is the fuse blown? Control No. Check items (unit operation) Replace the controller .
41 <T rouble Diagnosis of Outdoor Fan Motor> .....Applied for only SAP-CRV123 outdoor unit ● 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.
42 <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.
43 1 1-1. Measurement of Insulation Resistance ● The insulation is in good condition if the resistance exceeds 1M Ω . 1 1-1-1. Power supply cord Clamp the grounding wire of power cord with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the two power wires.
44 1 1-2. Checking Continuity of Fuse on PCB Ass’y ● Remove the PCB Ass’y from the electrical compo- nent box. Then pull out the fuse from the PCB Ass’y. (Fig. 5) ● Check for continuity using a multimeter as shown in Fig. 6. Fuse PCB Ass’y Fig.
45 12. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SER VICING UNIT 12-1. Characteristics of New Refrigerant R410A 12-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture.
46 ● Tubing precautions Refrigerant R410A is more easily affected by dust or moisture compared with R22, 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.
47 12-3. T ools Specifically for R410A ● For servicing, use the following tools for R410A ● To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, sizes of the service ports and flare nuts of the narrow tube service valve and wide tube service valve have been altered.
48 12-5. In Case of Compressor Malfunction 12-5-1. Procedure for replacing compressor (1) Recovering refrigerant ● Any remaining refrigerant inside the unit should not be released to the atmosphere, but recovered using the refrigerant recovery unit for R410A.
49 (5) Recharging ● Be sure to charge the specified amount of refrigerant in liquid state using the service port of the wide tube service valve. The proper amount is listed on the unit's nameplate. When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.
50 12-6. In Case Refrigerant is Leaking (1) Detecting Leaks ● Use the detector for R410A to locate refrigerant leak points. (2) Recovering refrigerant ● Never release the gas to the atmosphere; recover residual refrigerant using the refrigerant recovery unit for R410A, instead.
51 12-7. Charging Additional Refrigerant 12-7-1. When T ubes are Extended ● Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came with the indoor unit. Charge additional refrigerant in liquid state only.
