2. Install the drain nipple
g
and a commercially available drain hose (with 16 mm
inside diameter), and drain off the water.
(For the position where the drain nipple
g
is installed, refer to the installation
diagram of the indoor and outdoor units.)
• Check that the outdoor unit is horizontal, and route the drain hose at a
downward sloped angle with very little slack to the hose.
Flaring
1. Cut the pipe with a pipe cutter.
2. Insert a flare nut into the pipe, and flare the pipe.
• Projection margin in flaring: A (Unit: mm)
Rigid (Clutch type)
Imperial (Wing nut type)
3. Flaring size : B (Unit : mm)
• In case of flaring for R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that of R22 to adjust the
specified flare size. The copper pipe gauge is useful for adjusting projection margin size.
Tighten the connection
Align the centers of the connecting pipes and tighten the flare nut as much as possible with your fingers. Then tighten the nut with a
wrench and torque wrench as shown in the figure.
