NOTE: FOR DUCT LENGTH PLEASE SEE TABLE 2, 3, 4

A good flare should have the following characteristics:    

• Inside surface is glossy and smooth.    

• Edge is smooth.    

• Tapered sides are of uniform length.   

Cautions Before Connecting Tightly  

1. 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.  

2. 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 11).  

3. 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 12). 

4. Tighten the flare nuts, using the appropriate wrench. 

Connecting the Unit with Brazing Prodecure  

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. 

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 Fan Coil Unit and the copper tube used for installation (Figure 13).

- Expand the copper tube by using a swaging tool set as in Figure 14. 

4. 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 15.  

5. While welding copper tube. You should to Nitrogen flow in tube for protect soot occured.

Location and Preparation of Units 

Indoor Unit  

1. Select a convenient location that allows the air to reach every corner of the room and where it is easy to route the 

refrigerant tubing, wiring and drain to the outside.  

2. The ceiling construction should be strong enough to support the weight of the unit.  

3. The refrigerant tubing, drain piping and wiring conduit are connected through the wall.  

4. Refrigerant tubes between the indoor and the outdoor units and drain pipes should be as short as possible.  

5. If a refrigerant charge adjustment is necessary, follow the Installation Manual for the Outdoor Unit.  

Outdoor Unit  

See instructions for location and preparation of the unit in the Installation Manual for the Outdoor Unit.  

Installation Method: 

Indoor Unit  

After selecting the location to place the unit, follow these steps:  

1. Make a hole in the wall to route tubing and wiring through a locally 

purchased PVC pipe. 

  The hole should slope downwards slightly, towards the outside 

(Figure 1).   

2. 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. Hang the unit on a solid and level roof. Noise, vibration or leakage could 

occur on and unstable foundation (Figure 3, 4). For correct installation of 

duct work see (Figure 6).  

4. Support the unit solidly.  

5. To have access to electrical terminals, remove the right side junction box (Figure 2).  

6. Note that refrigerant tubing, interconnecting wiring and drain hose should go through the wall. 

Shape these items so that they will easily fit through the wall.    

Outdoor Unit  

See the proper installation method provided in the Installation Manual for the Outdoor Unit.

Connection of Refrigerant Tubing

Proper installation procedure is recommended in the Installation Manual Package, usually provided together with the 

outdoor unit. It is advisable to read before installing.  

The indoor unit refrigerant connections are located on the left hand side when facing the 

unit (Figure 7).   

Connecting the Units with Flaring Procedure  

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 tubing length.  

2. Remove burrs at the end of the copper tube with a tube reamer or file, as shown in 

Figure 8.    

When reaming, hold the tube end downward and be sure that no copper scraps fall into the 

tube (Figure 9).

3. Remove the flare nut from the unit and be sure to insert on the copper tube.  

4. Make a flare at the end of the copper tube with a flare tool (Figure 10).
