Not left in water
• Coil thermal insulation around a drain hose
extension, if running in the room.
• It is recommended to add an "intermediate
air vent" when the drain hose is extended
horizontally, or an "anti-back-flow air vent"
when the hose is exposed to high winds
on a high-rise building, for example. For
this purpose, employ a "T tube joint" (PVC-
made, commercially available) halfway in
the hose.

Connecting the refrigerant pipes
• Use pipes with thickness 0.8mm.
• Connect the pipes for the indoor unit first
and then for the outdoor unit.
• Bend the pipes carefully as not to damage
them.
• Do not over tighten the tubes; it may be
deformed or damaged.
Use a torque wrench, when possible. See
the table below for the flare nut tightening
torque.

Flaring the pipe end
1. Cutting with a pipe cutter
Cut at a right angle.
2. Deburring
Allow no cuttings in the pipe.
3. Putting in the flare nut
