Foundation for Installation

•Fix the unit tightly with bolts as shown below so that unit will not fall down due to earthquake or gust.

•Use the H-beam support as a base support

•Noise and vibration may occur from the floor or wall since vibration is transferred through the installation part depending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad shall be more than 200mm).

A Ensure that the corner part can be securely mounted. Otherwise, the support for installation may be bent.

	B Obtain and use the M10 anchor bolt.
	C The corner was not properly mounted.

WARNING

•Be sure to install unit in a place strong enough to withstand its weight.

Any lack of strength may cause unit to fall down, resulting in a personal injury.

•Have installation work in order to protect against a strong wind and earthquake. Any installation deficiency may cause unit to fall down, resulting in a personal injury.

•Especially take care for support strength of the floor surface, water drain processing (processing of water flown out from the Outdoor Unit during operation) and paths of the pipe and wiring when making a base support.

•Don't use a tube or pipe for water drain in the base pan and perform water drain processing by using the drain path. Water drain may not be done due to freezing of a tube or pipe.

PreparationofPiping

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.

Piping Connection

1.Form the piping according to its routing. Avoid bending and bending back the same piping point more than three times. (This will result in hardening the pipe.)

2.After deforming the piping, align centers of the union fitting of the Indoor Unit and the piping, and tighten them firmly with wrenches.

3.Connect pipe to the service valve or ball valve which is located below the Outdoor Unit.

4.After completing the piping connection, be sure to check if there is gas leakage in indoor and outdoor connection.

CAUTION

Use two wrenches and tighten with regular torque.

Refrigerant piping installation

Refrigerant piping installation

The method of connection consists of flare connections at the Indoor Units, flange connections for the piping of the Outdoor Unit and flare connections for the liquid piping. Note that the branched sections are brazed.

WARNING

Always use extreme care to prevent the refrigerant gas (R22) from the leakage while using fire or flame. If the refrigerant gas comes in contact with the flame from any source, such as a gas stove, it breaks down and generates a poisonous gas which can cause gas poisoning. Never weld in an unventilated room. Always conduct an inspection for gas leakage after installation of the refrigerant piping has been completed.

Cautionsin pipeconnection/valveoperation

Cut both the pipe and the valve with a cutter to suit the length

(Don't cut the length of less than 70mm)

Open status when both the pipe and the valve are in a straight line.

WARNING

After completing work, securely tighten both service ports and caps so that gas does not leak.

Pipe joint (auxiliary parts): Securely perform welding by passing nitrogen through the service valve port.

Flare nut: Loose or tighten flare nut by using the wrench with both ends. Coat the flare connection part with oil for a refrigerator.

Cap: Remove caps and operate valve, etc. After operation, always reattach caps (tightening torque of valve cap: 25Nm (250kg-cm) or more).

Service port: Make the refrigerant pipe empty and use the service port for filling additional refrigerant. Always reattach caps after completing work (tightening torque of service cap: 14Nm (140kg-cm) or more).
