(3) When it is checked that no air is leaked out, please
refer to Fig. 8 to properly insulate the pipe
connections with heat insulation material.
·
When carrying out heat insulation work, please use
the supplied heat insulation piece (3) (4) for the pipe
of the liquid side and the air supply side. In addition,
the connecting seams of the heat insulation piece (3)
and (4) for the connector shall face upward. (Please
use banding tie (9) to clamp both ends.)
·
Please use the middle seal (6) to wrap the surface of
the heat insulation piece (4) for the connector on the
pipe of the air supply side. (The flare nut section)
The pipe supplied on site must be heat insulated to the
connecting section of the pipe. In case that the pipe is
exposed, condensate can occur, and injury from burning
can also happen if touched.
CAUTION
·
Before welding the refrigerant pipe, please firstly carry
out nitrogen exchange, or when welding (Caution 2),
fill in nitrogen (Caution 1) in the refrigerant pipe, and
finally use the flare to connect to the indoor unit.
(Refer to Fig. 9)
CAUTION
1. In case that nitrogen is filled into the pipe when welding,
a relief valve shall be used to control the pressure to
0.02 MPa (0.2 kgf/cm
2
) (as if breeze flows along your
cheek).
2. When welding the connection section of the refrigerant
pipe, never use any welding flux. Please use phosphorus
and bronze brazing material (BCuP-2: JIS Z 3264/
BCu93P-710/795: ISO 3677) which does not need
welding flux. (In case that any welding flux containing
chlorine is used, the pipe can be corroded; and in case
that any welding flux containing fluorin is used, the ester
oil or ether oil can be deteriorated, and the refrigerant pipe
system can be further influenced.)

CAUTION
·
The connecting interface of the water drainage pipe
varies depending on different types, so please confirm
the name of the type, and use the installation method
suitable for the type.
(1) Install the water drainage pipe.

the water drainage pipe
Refrigerant pipe
Water drainage port for maintenance
(With a rubber plug)
·
When installing the water drainage pipe, ensure that
the water drainage is smooth.
·
The diameter of the water drainage pipe shall be larger
than or equal to that of the connection pipe (polyethylene
pipe; pipe dimensions: 20 mm; outer diameter: 26 mm).
(Not including the riser pipe)
