E-9
Connecting the Refrigerant Pipe
There are two refrigerant pipes of differing diameters:
 A smaller one for the liquid refrigerant
 A larger one for the gas refrigerant
 The inside of copper pipe must be clean & has no dust.
Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque
wrench, a spanner applying the following torque.
1
Must use insulator which is thick enough to cover the refrigerant pipe to
protect the condensate water on the outside of pipe falling onto the floor
and the efficiency of the unit will be better.
2
Cut off any excess foam insulation.
3
Be sure that there must be no crack or wave on the bended area.
4
It would be necessary to double the insulation thickness (10mm or more)
to prevent condensation even on the insulator when if the installed area is
warm and humid.
5
 If the pipes must be shortened refer to page10.

that the cut edge remains at a 90° angle with the side of the pipe. Refer to the
illustrations below for examples of edges cut correctly and incorrectly.
2
To prevent any gas from leaking out, remove all burrs at the cut edge of the
pipe, using a reamer.
3
Slide a flare nut on to the pipe and modify the flare.
4
Check that the flaring is correct, referring to the illustrations below for
examples of incorrect flaring.

Connect the flexible hose to the flexible hose port.
 Make sure that a rubber ring is installed on the drain hose port.
2
Install the drainpipe as shortly as possible.
 Give a slightly slant to the drainpipe for proper drainage of condensate
water.
 There must be no gap on the connected part so that the drainpipe is
not separated from the flexible hose .
3
Insulate the drainpipe, and then fix it as indicated.
4
CAUTION
Install air ventilation to drain condensate water
smoothly.
Check that the indoor unit is level with the ceiling by using the leveler.
Air ventilation
