Insulate the piping.
• Incorrect piping insulation may cause
condensation on the piping surfaces or degrade
the product performance.
• Make sure that the bent parts of the piping are
correctly covered with insulation.
Fix firmly so that there is no gap.

• You can use joined insulation (joining the pipes
and insulating them together), but avoid excessive
pressing.
• When joined insulation is used, apply the insulation
thickness one step higher.

CAUTION
• Make sure that the pipe insulation is free of gaps and
cracks, and apply adhesives specific to the insulation
joints so that moisture cannot enter through them.
• If the pipe insulation is exposed to the sun's
ultraviolet rays, wind tape around the insulated pipe
as a finishing work.
(When winding tape, be careful not to reduce the
thickness of insulation.)
• Be careful not to reduce the thickness of the
insulation at the bent parts of the pipe, the pipe
hanger, etc.
• If the thickness of insulation is reduced, apply
additional insulation to compensate the thickness.

Step 8 Installing the water pipes
1
Remove the caps from the water pipe inlet and outlet.

(water pipe outlet)
Air vent valve
IN
(water pipe inlet)
2
Be sure to check the positions of the water pipe inlet
and outlet of the fan coil unit by finding their labels
(IN and OUT) attached.
• The water pipe inlet label is printed with IN and
the water pipe outlet label with OUT.
• Note that the air vent valve is attached to the side
where you can find the water pipe outlet.
