REFRIGERANT PIPING CONNECTIONS
Headers
• The largest-capacity indoor unit must be installed closest to the Space II unit
• Install the Header in a horizontal plane.
• If the diameter of the refrigerant piping is different from the Header port size, trim to the desired section
using a pipe cutter.
• When the number of pipes to be connected is less than the number of available header branches,
install a cap to the unused ports.
• Headers should be insulated with the clam-shell jacket included in each kit.
