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 Notes Gas leak detector Detection of gas leaks The ones for HFC type refrigerant may be used. Vacuum Pump Vacuum drying May be used if a reverse flow check adaptor is attached.
- 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.
