• Label the indoor units A, B, C, D, etc. as appropriate
• Daikin does not have preference regarding install order
• Important for wiring and piping
• Piping and wiring must match
• If the system is piped A, B, & C then it MUST be wired A to A, B to B, and C to C, etc.

Install Guidelines
• When connecting a pipe to the unit body or
removing it, be sure to use a back up wrench
and torque wrench.
• For the work dimension and the tightening
torque of the flare section, see this table.
• When connecting a flare nut, apply oil to the
flare section (only the OUTER surface), and
screw the nut three or four times initially by
hand.
• Be sure to use the flare nuts included with
the condenser or fan coil.
