EFRIGERANT PIPING WORK

For refrigerant piping of outdoor unit, refer to the installation manual supplied with the outdoor unit.

Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, this can sometimes result in water leakage.

Before rigging tubes, check which type of refrigerant is used.

All field piping must be provided by a licensed refrigeration technician and must comply with the relevant local and national codes.

■

Use a pipe cutter and flare suitable for the used refrigerant.

■

To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end, or cover it with tape.

■

Use copper alloy seamless pipes (ISO 1337).

■

The outdoor unit is charged with refrigerant.

■

For local insulation, be sure to insulate local piping all the way into the pipe connections inside the unit.

Exposed piping may cause condensation or may cause burns when touched.

■

Make sure that no oil remains on plastic parts of the decoration panel (optional equipment).

Oil may cause degradation and damage to the plastic parts.

Cautions for brazing

■

Be sure to carry out a nitrogen blow when brazing.

Brazing without carrying out nitrogen replacement or releasing nitrogen into the piping will create large quantities of oxidized film on the inside of the pipes, adversely affecting valves and compressors in the refrigerating system and preventing normal operation.

■

When brazing while inserting nitrogen into the piping, nitrogen must be set to 0.02 MPa with a pressure-reducing valve (=just enough so that it can be felt on the skin).

■

Install the drain pipes.

Keep piping as short as possible and slope it downwards at a gradient of at least 1/100 so that air may not remain trapped inside the pipe.

Keep pipe size equal to or greater than that of the connecting pipe (vinyl pipe of 25 mm nominal diameter and 32 mm outer diameter).

Push the supplied drain hose as far as possible over the drain socket.

IRING EXAMPLE AND HOW TO SET THE

REMOTE CONTROLLER

How to connect wiring

(See figure 10)

■

Power supply wiring

Remove the control box lid (1) and connect the wires to the power supply terminal block inside (L, N) and connect the ground wire to the grounding terminal. While doing this, pull the wires inside through the hole in the casing and clamp the wires along with other wires using a clamp as indicated in the figure.

■

Unit transmission wiring and remote controller wiring

Remove the control box lid (1) and pull the wires inside through the hole in the casing and connect to the terminal block for unit

(P1, P2). Securely fix the wiring using a clamp as indicated in the figure.

■

After connection

Attach the small sealing (supplied with the unit) around the cables to prevent infiltrating of water from the outside into the unit. If two or more cables are used, divide the small sealing into the required number of pieces and wrap them around all the cables.

■

Attach the control box lid.

Use the specified electric wire. Connect the wire securely to the terminal. Lock the wire down without applying excessive force to the terminal. Use torques according to the table below.

Tightening torque (N•m)

Terminal block for unit transmission and remote controller

Terminal block for power supply

0.79~0.97

1.18~1.44

When attaching the control box lid, make sure not to pinch any wires.

After all wiring connections are done, fill in any gaps in the casing wiring holes with putty or insulation material (field supply) thus to prevent small animals or dirt from entering the unit from outside and causing short circuits in the control box.

2

Keep total current of crossover wiring between indoor units less than 12 A. Branch the line outside the terminal block of the unit in accordance with electrical equipment standards, when using two power wiring of a gauge greater than 2 mm

2

(Ø1.6).

The branch must be sheathed in order to provide an equal or greater degree of insulation as power supply wiring itself.

3

Do not connect wires of different gauge to the same grounding terminal. Looseness in the connection may deteriorate the protection.

4

Remote controller wiring and unit transmission wiring should be located at least 50 mm away from power supply wiring. Not following this guideline may result in malfunction due to electrical noise.

5

For the remote controller wiring, refer to the "Installation manual of the remote controller" supplied with the remote controller.

NOTE

The customer has the ability to select the remote controller thermistor.

6

Never connect the power supply wiring to the terminal block for transmission wiring. This mistake could damage the entire system.

7

Use only specified wires and tightly connect wires to the terminals. Be careful that wires do not place external stress on the terminals. Keep wiring in neat order so that they do not obstruct other equipment such as popping open the service cover. Make sure the cover closes tight. Incomplete connections could result in overheating, and in the worse case, electric shock or fire.

Precautions

1.

A single switch can be used to supply power to units on the same system. However, branch switches and branch circuit breakers must be selected carefully.

2.

For a group control remote controller, choose the remote controller that suits the indoor unit which has the most functions.

3.

Do not ground the equipment on gas pipes, water pipes, lightning rods or crossground with telephones. Improper grounding could result in electric shock.
