  • Page 4: Safety Cautions

    Safety Cautions Carefully read the following information in order to operate the air conditioner correctly. Below are listed three kinds of Safety Cautions and Suggestions. Incorrect operations may result in severe consequences of death or serious injuries. WARNING! CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may cause serious consequences.
  • Page 5 Safety Cautions Installed electrical-leaking circuit breaker. It easily cause electrical shock without circuit breaker. Air-conditioner can't be installed in the environment with inflammable gases because the inflammable gases near to air-conditioner may cause fire hazard. Please let the dealer be responsible for installing the conditioner.
  • Page 6 Safety Cautions Have the unit professionally installed. Improper installation by an unqualified person may result in water leak, electric shock, or fire. Place the unit on a stable, level surface that withstands the weight of the unit to prevent the unit from tipping over or falling causing injury as a result.
  • Page 7 Consult the dealer for necessary measures to take. When relocating the air conditioner, consult the dealer or a specialist. Improper installation may result in water leak, electric shock, or fire.
  • Page 8 Safety Cautions Store the piping to be used during installation indoors, and keep both ends of the piping sealed until immediately before brazing.(keep elbows and other joints wrapped in plastic.) If dust, dirt, or water enters the refrigerant cycle, it may cause the oil in the unit to deteriorate or may cause the compressor to malfunction.
  • Page 9 Safety Cautions Before installing(Relocating) the Unit or Performing Electric Work Ground the unit. Do not connect the grounding on the unit to gas pipes,water pipes, lightning rods,or the grounding terminals of telephones. Improper grounding presents a risk of electric shock, smoke, fire, or the noise caused by improper grounding may cause the unit to malfunction.
  • Page 10: Read Before Installation

    Read Before Installation Items to Be Checked <1>. Verify the type of refrigerant used by the unit to be serviced. Refrigerant Type: R410A <2>. Check the symptom exhibited by the unit to be serviced. Look in this sercice handbook for sympeoms relating to the refrigerant cycle. <3>.
  • Page 11 Read Before Installation 2. Tools and materials that may be used with R410 with some restrictions Tools/Materials Gas leak detector Detection of gas leaks Vacuum Pump Vacuum drying Flare Tool Flare machining of piping Refrigerant Recovery Recovery of refrigerant Equipment 3.
  • Page 12 Read Before Installation <Piping Materials/Radial Thickness> Use pipes made of phosphorus deoxidized copper. Since the operation pressure of the units that use R410A is higher than that of the units for use with R22, use pipes with at least the radial thickness specified in the chart below. (Pipes with a radial thickness of 0.7mm or less may not be used.) Size(mm) Size(inch)
  • Page 13 Read Before Installation *The table shows the standards in Japan. Using this table as a reference, choose pipes that meet the local standards. Airtightness Test No changes from the conventional method .Note that a refrigerant leakage detector for R22 or R407C cannot detect R410A leakage.
  • Page 14 Read Before Installation Charging Refrigerant R410A must be in a liquid state when charging. Reasons : 1. R410A is a pseudo-azeotropic refrigerant (boiling point R32= -52*, R125= -49*) and can roughly be handled in the same way as R22; however, be sure to fill the refrigerant from the liquid side, for doing so from the gas side will somewhat change the composition of the refrigerant in the cylinder.

  • Page 20 Installation Procedure 5. Air discharging method After finishing connection of refrigerant pipe, it shall perform air tightness test. The air tightness test adopts nitrogen tank to give pressure according to the pipe connection mode as the following figure shown. The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas and liquid valve rods).
  • Page 21 CAUTION:If the refrigerant of the air conditioner leaks, it is necessary to make all the refrigerant out. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.
