  • Page 238 5.3.3 Expanding copper piping ends  Notes for installers  Ends of copper piping can be expanded so that another length of piping can be inserted and the joint brazed.  Insert the expanding head of the pipe expander into the pipe. After completing pipe expansion, rotate the copper pipe a few degrees to rectify the straight line mark left by the expanding head.

  • Page 243 5.7 Piping Connections between Outdoor Units The piping connecting the outdoor units should be horizontal and must not be higher than the refrigerant outlets. If necessary, to avoid obstacles the piping may be vertically offset below the outlets. When inserting a vertical offset to avoid an obstacle, the whole outdoor piping should be offset, rather than just the section adjacent to the obstacle.
  • Page 244 5.8.2 Procedure  Notes for installers Warning Only use nitrogen for flushing. Using carbon dioxide risks leaving condensation in the piping. Oxygen, air, refrigerant, flammable gases and toxic gases must not be used for flushing. Use of such gases may result in fire or explosion. Procedure The liquid and gas sides can be flushed simultaneously;...

  • Page 247 5.10.2 Procedure  Notes for installers During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C. Therefore a vacuum pump capable of maintaining a pressure of -756mmHg or lower should be used.
