  • Page 3: Safety Precaution

    SAFETY PRECAUTION CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilising refrigerant R410A Use new refrigerant pipes. Do not use refrigerant other than R410A. In case of using the existing pipes for R22, be careful with If other refrigerant (R22 etc.) is used, chlorine in refrige- the followings.
  • Page 4 [2] Storage of Piping Material (1) Storage location Store the pipes to be used indoors. (Warehouse at site or owner’s warehouse) Storing them outdoors may cause dirt, waste, or water to infiltrate. (2) Pipe sealing before storage Both ends of the pipes should be sealed until immediately before brazing. Wrap elbows and T’s in plastic bags for storage.
  • Page 5 [3] Brazing No changes from the conventional method, but special care is required so that foreign matter (ie. oxide scale, water, dirt, etc.) does not enter the refrigerant circuit. Example: Inner state of brazed section When non-oxide brazing was not used When non-oxide brazing was used Items to be strictly observed: Do not conduct refrigerant piping work outdoors on a rainy day.
  • Page 6 [4] Airtightness Test No changes from the conventional method. Note that a refrigerant leakage detector for R22 cannot detect R407C leakage. Halide torch R22 leakage detector Items to be strictly observed: Pressurize the equipment with nitrogen up to the design pressure and then judge the equipmentÕs airtightness, taking temperature variations into account.
  • Page 7 [6] Additional refrigerant charge When charging directly from cylinder · Check that cylinder for R410A on the market is syphon type. · Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.) Unit Gravimeter [7] Service tools Use the below service tools as exclusive tools for R410A refrigerant.
