Step 8 Installing The Water Pipes - Samsung AGTN1DKH Series Installation Manual

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.

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.

CAUTION
• Failure to connect the water pipes may cause
performance degradation.
• Be sure to insulate both the inlet and outlet pipings.
3 Before connecting the water pipes, be sure to install a
2-way electric valve.
• Be sure to install the 2-way electric valve on the
inlet side pipe.
• When circulating cold/hot water, open the air vent
valve and use a tube to receive water so that the
air inside the pipe and coil is sufficiently removed,
and then close the valve. Failure to do so may cause
performance degradation and noise.
• Before connecting the water pipes., check if
the water pipe Flexible tube (loose nut PF 3/4")
specification is correct. After connecting the water
pipes, remove foreign objects from them, and then
circulate water to check for water leakage.
