Deburring
The indoor unit refrigerant piping
connections are located on the right
hand side when facing the unit
(Figure 11).
Bending
5. When bending the tube, be
careful not to crush it. To prevent
crushing of the tube, bend it
gently and do not bend the tube
at a radius curvature of less than
100 mm.
Before
After
Figure 13
4. Make a flare at the end of copper
tube with a flare tool (Figure
14, 15).
6. If the copper tube is bent or
pulled too often, it will become
stiff. Do not bend the pipe more
than three times at one place.

7. Be sure to apply a sealing cap or
water-proof tape to prevent dust
or water from getting into the
tubes before they are used.
Flare tool
1. Flaring (If piping is procured or
cut at the site). Cut the copper
tube to the required length with
a tube cutter. It is recommended
to cut approx. 30-50 cm. longer
than the tubing length you
estimate.
Figure 14
8. Be sure to apply refrigerant
lubricant to the matching
surfaces of the flare and union
before connecting them
together. This is effective for
reducing gas leaks (Figure 16).
L
2. Hold each pipe downward when
cutting and remove burrs at the
end of the copper tube with a
tube reamer or file. This process
is important and should be done
carefully to make a good flare
(Figure 12 and Figure 13).

with bare gas line.
9. For proper connection, align the
union tube and flare tube straight
with each other, then screw in the
flare nut lightly at first to obtain a
smooth match (Figure 17).
7. Precautions should be taken to
avoid heat damage to the
pressure tap valve core during
brazing. It is recommended that
a wet rag be wrapped around the
valve body.
1. Cut the copper tube to the
required length with a tube cutter.
It is recommended to cut approx.
20-30 cm. longer than the tube
length you estimate.
8. It is recommended to use braze
shield, soak pad in water and
place over suction and liquid
lines to protect unit finish.
9. To braze the copper tube, before
brazing a copper tube to a solder
coupling or a copper tube to an
expanded tube, do not forget to
keep them tight as shown in
Figure 21, 22.
2. Remove burrs at the end of the
copper tube with a tube reamer
(Figure 12).
3. There are 2 ways to connect the
copper tube
Union Flare nut
- Use a coupling between the
copper tube of indoor unit and
the copper tube used for
installation (Figure 19).

10. Tighten the flare nut to the
specified tightening torque with
torque wrench and adjustable
wrench (Figure 18).

Condensate Drain Piping
-
The drain hose should run
straight down the wall to a
level where the runoff will not
stain the wall.
-
When the drain hose is placed
in the room, insulate the hose
with foam polyethylene to
avoid damage to the ceiling or
furniture.
-
-
There should be no traps.
Avoid putting the end of the
hose in water.
-
After completing installation of
refrigerant lines, wiring and
drain connections, bind the
tubing, wiring and drain hose
(check if local codes permit
binding) into a bundle by using
tape at 100 or 200 mm (4" to
8") intervals. Make sure the
drain hose is at the bottom of
the bundle (Figure 24).
To conveniently drain the
system, the drain hose must
slant downward, with a slope
of at least 1 : 50 to prevent
leakage. Figure 23 shows the
unit in the floor mounted
position.

Electrical Installation
All wiring and grounding must
comply with local electrical codes.
Indoor Unit
Remove the right side panel and
return grille (see previous
instructions), to access the terminal
base.
1. Wiring
Important Safeguards:
-
Check the unit nameplate
for electrical rating.
Be sure wiring is done
according to local codes
and wiring diagram.
-
Pass the system wiring
through the PVC pipe (both
power and control lines) to
interconnect indoor and
outdoor units.
-
Use a separate power line
with circuit breaker for each
air conditioning unit.
Connect electrical ground
to all units.
-
-
Connect the wire terminals to
the terminal base (see
connection indication on
system wiring diagram).
Make sure all connections are
tight.
-
-
Wiring should not touch
refrigerant
tubing,
compressor, motors or
moving parts.
The manufacturer will
accept no responsibility for
problems caused by
unauthorized changes in
the internal wiring.
Outdoor unit
Outdoor Unit - Indoor Unit Electrical
Interconnection should be in
accordance with the applicable
system wiring diagram and indoor
unit diagrams.
-
-
Connect the wiring firmly.
Outdoor unit diagram are contained
in the outdoor unit Installer Manual.
2. Electrical Connections
See Section: Wiring System
Diagram
Note:
-
All wiring must comply with
national state and local codes.
-
