Page 17: 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: R32 (2) Check the symptom exhibited by the unit to be serviced. Look in this service handbook for symptoms relating to the refrigerant cycle. - Page 18 R32 leakage Test No changes from the conventional method. Note that a refrigerant leakage detector for R22 or R410A cannot detect R32 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.
