3. Connecting Pipes to the Indoor Unit

3-1. Preparation of Piping

Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

1) Cut the pipes and the cable.

■ Use the accessory piping kit or the pipes purchased locally.
■ Measure the distance between the indoor and the outdoor unit.
■ Cut the pipes a little longer than measured distance.
■ Cut the cable 1.5m longer than the pipe length.

2) Burrs removal

■ Completely remove all burrs from the cut cross section of pipe/tube.
Put the end of the copper tube/pipe to downward direction as you remove burrs in order to avoid to let burrs drop in the tubing.

3) Putting nut on

■ Remove flare nuts attached to indoor and outdoor units, than put them on pipe/tube having completed burr removal.

(Not possible to put them on after flaring work)

4) Flaring work

- Carry out flaring work using flaring tool as shown below. Unit(mm)

Outside Diameter		"A"
1/4"	∅6.35	1.1~1.3
3/8"	∅9.52	1.5~1.7
1/2"	∅12.7	1.6~1.8
5/8"	∅15.88	1.6~1.8
3/4"	∅19.05	1.9~2.1

Firmly hold copper tube in a bar(or die) as indicated dimension in the table above.

5) Check

■ Compare the flared work with figure.
If flare is noted to be defective, cut off the flared section and do flaring work again.

6) Pipe bending

Annealed copper pipe with small diameter ( 6.35 or 9.52 ) can be easily bent manually. In this case, secure large R(radius) for the bend section and gradually bend pipe. If annealed copper pipe is large in diameter ( 15.88 or 19.05 ), bend pipe with bender. Use bender appropriate for the pipe diameter.

7) Brazing

In refrigerant piping, bending (in particular, acute bending) must be minimized to reduce piping resistance. Bending is, however, necessary in some places by virtue of the installation position of devices auxiliary to the packaged air conditioner, or of the building structure, piping distance or finishing appearance. If a more acute bend is required than that attainable by pipe bender, perform brazing using ready-made elbow. Aside from this function, brazing also serves to connect straight pipes, generally using ready-made sockets. While brazing, protect piping against heat with wet cloth to avoid damaging valve packing or burning thermal insulator with burner heat. While brazing, blow inert gas (nitrogen gas or carbonic gas) to prevent formation of oxidation film in copper piping; otherwise, the refrigerant circuit will clog. The blowing of nitrogen gas (or carbonic gas) through 3-way valves is described in the following:

8) Refrigerant piping(Flare piping)

When connecting piping, be sure to keep piping dry(keep piping away from water), clean (keep piping away from dust) and airtight (avoid refrigerant leakage).

When connecting piping on rainy days or making a through-hall in wall, take due care to prevent water or plaster from entering piping.

CAUTION

a. This procedure is designed to prevent formation of oxidation film by filling piping with inert gas. Note that excessive gas pressure will generate pinholes at brazed points.
(Nitrogen gas: Supply pressure 0.05\~0.1kg/cm²G)
b. When supplying inert gas, be sure to open one end of piping.

10. E.S.P.(External Static Pressure) Setting

(1) Open the rear cover of the wired remote-controller to set the mode.
(2) Select one of three selectable modes as follows.

■ Without Zone System

1. Position V-H, F-H:

• This position sets the maximum E.S.P as a default set.

1. Position V-L:

- This position sets the minimum E.S.P as a default set.

■ With Zone System

1. Position V-H:

• Maximum E.S.P setting & Fan speed is varied according to the state of dampers by micom.

1. Position F-H:

• Maximum E.S.P setting & Fan speed doesn't vary according to the opening & Closing of dampers.

1. Position V-L:

- Minimum E.S.P setting & Fan speed is varied according to the state of dampers by micom.

*Maximum : 3mmAq

Minimum : All-0mmAq

(3) Move the slide switch to set position.
