Location and Preparation of Unit

Figure 1

Figure 2

1. Select an appropriate position that
allows every corner of the room to
be uniformly air conditioned and
where it is easy to route the
refrigerant tubing (Figure 1).

2. Ensure that the floor construction
is sufficient to fully support the
weight of the indoor unit.

3. Consideration must be given to
ensure an unobstructed flow of
supply and return air.

4. Refrigerant tubes between indoor
and outdoor units should be kept
as short as possible.

5. Length of the condensate drain
hose should be kept as short as
possible.

6. Do not install unit in direct sunlight
or near other heat sources as this
may affect performance. Do not
allow outside air to directly enter
unit or condensate may form at the
unit s discharge.

7. Recommended service clearance
as shown in (Figure 2).

Figure 4

Indoor Unit

1. Select a location to route tubing,
wiring and drain pipe between the
indoor and outdoor units.

2. Make a hole in the wall using a key
hole saw or hole-cutting drill
attachment.

The hole should be made at a slight
downward slant to the outdoor side
(Figure 3).

Before cutting, check that no pipes or
studs are directly behind the place to
be cut. Avoid areas where electrical
wiring or conduits are located.

3. Place the unit on a solid and level
foundation.

4. Tubing, wiring and the drain pipe
can be routed to rear or left and
right side of the unit.

5. To gain access to the electrical
terminals, the drain and the
refrigerant lines, remove the return
air grille and bottom panel.

5.1 Remove a screw at return air grille

(Figure 4).

5.2 Pull the return air grille forward

and lift up to remove it (Figure 5).

5.3 Unscrew at the bottom panel, pull

forward and lift up to remove the
panel. The electrical box will be
on the left hand side, the drain
and refrigerant lines will be on the
right hand side when facing front
(Figure 6).

5.4 Unscrew at the electrical box to

remove the cover, the electrical
terminal will be placed inside the
box (Figure 7).

6. Replace the cover of electrical box,
bottom panel and the return air
grille after the installation of wiring,
tubing and piping is completed.

Connecting the Unit with
Brazing Procedure

1. Cut the copper tube to the
required length with a tube cutter.
It is recommened to cut approx.
20-30 cm. longer than the tube
length you estimate.

2. Remove burrs at the end of the
copper tube with a tube reamer
(Figure 8).

3. There are 2 ways to connect the
copper tube.

- Use a coupling between the
copper tube of indoor unit and
the copper tube used for
installation (Figure 9).

- Expand the copper tube by using
a swaging tool set (Figure 10).

4. Clean internal and extenal surfaces
of coupling or expanded tube prior
to brazing.

5. Insulate the entire suction line.

6. Do not allow uninsulated liquid line
to come in direct contact with bare
suction line.

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.

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 11, 12).

10. Use a dry nitrogen purge and
brazing alloy without flux when
brazing the field line to the copper
factory connection. Flow dry
nitrogen into either valve pressure
tap port, through the tubing and
out the other port while brazing.

11. Braze using accepted good
brazing techniques.

- The drain hose should run straight
down the wall to a level where the
run off will not stain the wall.

- There should be no traps. Avoid
putting the end of the hose in
water.

- To conveniently drain the system,
the drain hose must slant
downward, with a slope of at least
1 : 50 to prevent leakage.

- When the drain hose is placed in
the room, insulate the hose with
foam polyethylene to avoid
damage to the ceiling or furniture.

- 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 12).

Electrical Installation

All wiring and grounding must comply
with local electrical codes.

1. Wiring

Important Safeguards:

- Check the unit nameplate for
electrical rating. Be sure wiring
is done according to local
codes and wiring diagram.

- Use a separate power line with
circuit breaker for each air
conditioning unit.

- Connect electrical ground to all
units.

- 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.

- Connect the wiring firmly.

2. Electrical Connections

See Section: Typical Wiring
Diagram

Indoor Unit

Remove the return air grille and cover
of electrical box (see previous
instructions) to access the terminal base.

- Connect the wire terminals
to the terminal base.
(See connection indication on
system wiring diagram).

- Make sure all connections are
tight.

Outdoor Unit

Outdoor unit - indoor unit electrical
interconnection should be in
accordance with the applicable
system wiring diagram and indoor
unit diagrams.

Outdoor unit diagram is contained in
the outdoor unit Installation Manual

Note:

- All wiring must comply with
national state and local codes.

- After completing the connections,
re-confirm them to be in
accordance with the unit and
system wiring diagrams.
