Page 7: 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 service handbook for symptoms relating to the refrigerant cycle. - Page 8 Read Before Installation Piping Materials Types of Copper Pipes (Reference) Maximum Operation Pressure Applicable Refrigerants 3.4MPa R22, R407C 4.15MPa R410A Use pipes that meet the local standards. 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.
- Page 9 Read Before Installation Air Tightness Test No changes from the conventional method. Note that a refrigerant leakage detector for R22 or R407C cannot detect R410A leakage. Halide torch R22 or R407C leakage detector Items to be strictly observed : Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment's air tightness, taking temperature variations into account.
