Adoption of New Refrigerant This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional refrigerant R22 in order to prevent destruction of the ozone layer. WARNING Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. Do not attempt it yourself. The cleaning diagram for the air filter is there for the service person, and not for the customer. CONTENTS SAFETY CAUTION .....

SAFETY CAUTION The important contents concerned to the safety are described on the product itself and on this Service Manual. Please read this Service Manual after understanding the described items thoroughly in the following contents (Indications/Illustrated marks), and keep them.
WARNING Check earth wires. Before troubleshooting or repair work, check the earth wire is connected to the earth terminals of the main unit, otherwise an electric shock is caused when a leak occurs. If the earth wire is not correctly connected, contact an electric engineer for rework. Do not modify the products. Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury. Prohibition of modification. Use specified parts. Do not bring a child close to the equipment.
WARNING Insulator check Ventilation After the work has finished, be sure to use an insulation tester set (500V Megger) to Ω or more between the charge section and the non-charge check the resistance is 2MΩ metal section (Earth position). If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side. When the refrigerant gas leaks during work, execute ventilation. If the refrigerant gas touches to a fire, poisonous gas generates.
• New Refrigerant (R410A) This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer. 1. Safety Caution Concerned to New Refrigerant The pressure of R410A is high 1.6 times of that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed.
4. Tools 1. Required Tools for R410A Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary, etc. Accordingly, the tools to be used are classified into the following three types.

Joints For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants. a) Flare Joints Flare joints used to connect the copper pipes cannot be used for pipings whose outer diameter exceeds 20 mm. In such a case, socket joints can be used.
c) Insertion of Flare Nut d) Flare Processing Make certain that a clamp bar and copper pipe have been cleaned. By means of the clamp bar, perform the flare processing correctly. Use either a flare tool for R410A or conventional flare tool. Flare processing dimensions differ according to the type of flare tool. When using a conventional flare tool, be sure to secure “dimension A” by using a gauge for size adjustment. ØD A Fig.
6˚ to 4 45˚ B A C 43˚ D to 4 5˚ Fig. 6-2-2 Relations between flare nut and flare seal surface 2. Flare Connecting Procedures and Precautions a) Make sure that the flare and union portions do not have any scar or dust, etc. b) Correctly align the processed flare surface with the union axis. c) Tighten the flare with designated torque by means of a torque wrench. The tightening torque for R410A is the same as that for conventional R22.
6-3. Tools 6-3-1. Required Tools Refer to the “4. Tools” (Page 8) 6-4. Recharging of Refrigerant When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the following steps. Recover the refrigerant, and check no refrigerant remains in the equipment. When the compound gauge’s pointer has indicated –0.1 Mpa (–76 cmHg), place the handle Low in the fully closed position, and turn off the vacuum pump’s power switch.
1) Be sure to make setting so that liquid can be charged. 2) When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down. It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant. Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the cylinder upside down if cylinder is not equipped with siphon.
2. Characteristics required for flux 6-5-3. Brazing • Activated temperature of flux coincides with the brazing temperature. • Due to a wide effective temperature range, flux is hard to carbonize. • It is easy to remove slag after brazing. • The corrosive action to the treated metal and brazing filler is minimum. • It excels in coating performance and is harmless to the human body.
6-6. Instructions for Re-use Piping of R22 or R407C Instruction of Works: The existing R22 and R407C piping can be reused for our digital inverter R410A products installations. NOTE) Confirmation of existence of scratch or dent of the former pipes to be applied and also confirmation of reliability of the pipe strength are conventionally referred to the local site. If the definite conditions can be cleared, it is possible to update the existing R22 and R407C pipes to those for R410A models. 6-6-1.
6-6-5. Final Installation Checks Is there no scratch or dent on the existing pipes? Existing pipe: NO * Use a new pipes. NO Is it possible to operate the existing air conditioner? YES * After the existing air conditioner operated in cooling mode for approx. 30 minutes or longer*, recover the refrigerant. * For cooling the pipes and recovering of oil • Refrigerant recovery: Pump down method Nitrogen gas pressure 0.
6-6-6. Handling of Existing Pipe 6-6-7. Recovery Method of Refrigerant for RAV-SP1104AT-E, RAV-SP1404AT-E When using the existing pipe, carefully check it for the following: • Wall thickness (within the specified range) • Scratches and dents • Water, oil, dirt, or dust in the pipe • Flare looseness and leakage from welds • Deterioration of copper pipe and heat insulator • Use the refrigerant recovery switch SW801 on the P.C.

The outdoor fan is controlled by every 1 tap of DC fan control (14 taps).
4. Coil heating control 1) This control function heats the compressor by turning on the stopped compressor instead of a case heater. It purposes to prevent stagnation of the refrigerant inside of the compressor. 2) As usual, turn on power of the compressor for the specified time before a test run after installation; otherwise a trouble of the compressor may be caused.
7. Current release value shift control Current release control value (11) [A] 1) This control purposes to prevent troubles of the electronic parts such as the compressor driving elements and the compressor during cooling operation. 2) The current release control value (I1) is selected from the following table according to TO sensor value. Temperature range SP110, SP140 44°C ≤ To 15.0 39°C ≤ To < 44°C 17.7 To < 39°C 20.0 TO error 15.0 8.
10. Defrost control 1) In heating operation, defrost operation is performed when TE sensor satisfies any condition in A zone to D zone. 2) During defrosting operation, it finishes if TE sensor continued 12°C or higher for 3 seconds or continued 7°C ≤ TE < 12°C for 1 minute. The defrost operation also finishes when it continued for 10 minutes even if TE sensor temperature was 7°C or lower. 3) After defrost operation was reset, the compressor stopped for approx.
