Location and Preparation of Units
1. Select an appropriate position that allows every corners of the room to be uniformly air conditioned and where it is easy to route the refrigerant tubing.
2. Ensure that the floor or ceiling construction is sufficient to fully support the weight of the indoor unit.
3. Consideration must be given to assure an unobstructed flow of supply and return air.
4. Refrigerant tubes between indoor and outdoor units should be as short as possible.
5. Length of the condensate drain hose should be kept as short as possible (Figure 1).

Unit Installation
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 5).
Outdoor side
Indoor side
Figure 5
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 through and drain pipe of low wall and floor mounted units can be routed, rear or right side of unit when facing front. Ceiling mounted can be routed straight downward. Pull air filters upward (Figure 6).
5.
6. Unscrew at the return grille (Figure 7).
Figure 7
7. Unscrew at the grille bottom hinges, pull out the screw, and unscrew at the side panel front (Figure 8). Then, push down on
panel front and pull up
the side (Figure 9).

Connection of Refrigerant Tubing
The indoor unit refrigerant line connections are flared both 50 Hz and 60 Hz. Installation brazing, leak testing, and evacuation of refrigerant lines are covered in the Installer Manual, packaged with the outdoor unit. Read the instructions before installing the refrigerant lines.
The indoor unit refrigerant piping connections are located on the right hand side when facing the unit (Figure 11).
Figure 11
Connecting the unit with flaring procedure. (Only for MCX 512-536)
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.
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).

Reamer
Figure 12
When reaming, hold the tube end downward and be sure that no copper scraps fall into the tube.
3. Remove the flare nut from the unit and be sure to mount it on the copper tube.

4. Make a flare at the end of copper tube with a flare tool (Figure 14, 15).

1.9 to 2.2 mm (12.7 mm dia)
2.1 to 2.4 mm (15.88 mm dia)
Figure 15
A good flare should have the following characteristics:
- Inside surface is glossy and smooth.
- Edge is smooth.
- Tapered sides are of uniform length.
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.
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.
Cautions before connecting tubes tightly
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.
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).

Connecting the unit with brazing procedure (Only for MCX 042-060)
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.
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
- Use a coupling between the
copper tube of indoor unit and the copper tube used for installation (Figure 19).

- Expand the copper tube by
using a swaging tool set as in Figure 20.

5. Insulate the entire gas line.
6. Do not allow uninsulated liquid line to come in direct contact with bare gas 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 21, 22.

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.

Condensate Drain Piping
- The drain hose should run straight down the wall to a level where the runoff 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. Figure 23 shows the unit in the floor mounted position.
Indoor unit
Slant
Drain hose
Figure 23
- 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 24).

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: Wiring System Diagram
Indoor Unit
Remove the right side panel and return grille (see previous instructions), to access the terminal base.
- Pass the system wiring through the PVC pipe (both power and control lines) to interconnect indoor and outdoor units.
- 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 are contained in the outdoor unit Installer 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.
