• If the pipes require brazing ensure that OFN(Oxygen Free Nitrogen) is flowing through the system.
• Nitrogen blowing pressure range is 0.02 to 0.05 MPa.

Step 8 Connecting up and removing air in the circuit

CAUTION

- When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.

The air in the indoor unit and in the pipe must be evacuated. If air remains in the refrigerant pipes, it will affect the compressor either reduce cooling capacity or lead to a malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the right figure.

1 Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut. 2 Referring to the illustration below, tighten the flare nut on section D first manually and then with a torque wrench, applying the following torque.

Outer Diameter (mm) Torque (N·m)
ø 6.35 14 to 18
ø 9.52 34 to 42
ø 12.70 49 to 61
ø 15.88 68 to 82
ø 19.05 100 to 120

3 Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port as shown at the figure.

CAUTION

• The designs and shape are subject to change according to the model. 4 Open the valve of the low pressure side(A) of manifold gauge anticlockwise.

5 Purge the air from the system using vacuum pump for about 10 minutes.

• Close the valve on the low-pressure side of the manifold gauge by turning it clockwise.
• Ensure that the pressure gauge reads -0.1 MPa (-76 cmHg) after about 10 minutes. This step is crucial to prevent gas leaks.
• Turn off the vacuum pump.
• Disconnect the hose from the low-pressure side of the manifold gauge.

6 Open the stop valves on both the liquid and gas sides.

7 Install the valve stem nuts and the service port cap onto the valve, and tighten them to a torque of 183 kgf·cm using a torque wrench.

8 Check for gas leaks.

- At this point, especially check for gas leaks from the 3-way valve's stem nuts (A port) and the service port cap.

CAUTION

• Connect the indoor and outdoor units using pipes with flared connections (not supplied). For the lines, use insulated, unwelded, degreased, and deoxidized copper pipe (Cu DHP type to ISO 1337 or UNI EN 12735-1), suitable for operating pressures of at least 4200 kPa and a burst pressure of at least 20700 kPa. Copper pipe intended for hydro-sanitary applications is completely unsuitable.
• For sizing and limits (height difference, line length, max. bends, refrigerant charge, etc.), refer to the "Connecting refrigerant pipe section".

Step 9 Adding refrigerant (R-410A)

- The outdoor unit is pre-charged with enough refrigerant for standard piping. Therefore, additional refrigerant must be added if the piping is extended. This operation should only be performed by a qualified refrigeration specialist. To determine the amount of refrigerant to add, see "Calculating the quantity of refrigerant to add" on page 20.

1 Check that the stop valve is fully closed. 2 AC024TXADKC: Charge the refrigerant through the service port of the gas stop valve. AC036/048TXADKC: Charge the refrigerant through the service port of the liquid stop valve.

NOTE

- AC036/048TXADKC: Do not charge the refrigerant through the service port of the gas stop valve.

3 AC024TXADKC: Charge the refrigerant by taking the following steps:

AC036/048TXADKC: If you have any difficulty charging the refrigerant as described in the steps above, take the following steps:

a. Open the liquid stop valve and gas stop valve. b. Operate the air conditioner by pressing the K2 button on the outdoor unit PCB. c. After about 30 minutes, charge the refrigerant through the service port of the gas stop valve.

Calculating the quantity of refrigerant to add

The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit situation before adding refrigerant. This operation can only be performed by a qualified refrigeration specialist.

Single installation outdoor unit

Interconnection pipe length (m)	AC024TX ADKC	AC036TX ADKC	AC048TX ADKC
0~30	+10g/m over 5m	+50g/m over 30m	+50g/m over 30m
30~40
40~50
50~60
60~70
70~75

Step 10: Performing the gas leak test

LEAK TEST WITH NITROGEN (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it is the responsibility of the installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 0.2MPa, less than 4MPa (gauge).

LEAK TEST WITH R-410A (after opening valves)

Before opening valves, discharge all the nitrogen into the system and create vacuum. After opening valves check leaks using a leak detector for refrigerant R-410A. Once you have completed all the connections, check for possible leaks using leak detector specifically designed for HFC refrigerants.

- AC024TXADKC

- AC036/048TXADKC

- The designs and shape are subject to change according to the model.

Step 11 Connecting the drain hose to the outdoor unit

1. Make space more than 80 mm between the bottom of the outdoor unit and the ground for installation of the drain hose, as shown in the figure. 2. Insert the drain plug into the hole on the underside of the outdoor unit. 3. Connect the drain hose to the drain plug. 4. Ensure that the drained water runs off correctly and safely.

5. Be sure to plug the rest of the drain holes not connected with drain plugs using drain caps.

• When installing the product, make sure that the rack is not placed under the drain hole.
• If the product is installed in a region of heavy snow, allow enough separation distance between the product and the ground.

Step 12 Insulating the refrigerant pipes

Once you have checked that there are no leaks in the system, you can insulate the piping and hose.

1. To avoid condensation problems, place an insulator around each refrigerant pipe.

NOTE

- When insulating the pipe, be sure to overlap the insulation.

- The insulation has to be produced in full compliance with European regulation reg. EEC/EU 2037/2000, which requires the use of sheath insulation forms without using CFC and HCFC gases for health and the environment.

CAUTION

- When insulating the pipe, use a non-slit insulator.

2. Select the insulation of the refrigerant pipe.

• Insulate the gas side and liquid side pipe, referring to the thickness according to the pipe size. - Less than indoor temperature of 30°C and humidity of 85% is the standard condition. If installing in a high humidity condition, use one grade thicker insulator by referring to the table below. If installing in unfavorable conditions, use a thicker one. - Insulator's heat-resistance temperature should be more than 120°C.

Pipe	Pipe size (mm)	Insulation Type (Heating/Cooling)		Remarks
		Standard [Less than 30°C, 85%]	High humidity [over 30°C, 85%]
		EPDM, NBR (mm)
Liquid pipe	∅6.35 ~ ∅9.52	9 t 9 t		Internal temperature is higher than 120°C
	∅12.7 ~ ∅19.05	13 t 13 t
Gas pipe	∅6.35 13 t	19 t
	∅9.52 ~ ∅19.05	19 t 25 t

- When installing insulation in places and conditions below, use the same insulation that is used for high humidity conditions.

– High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is covered by earth and sand.)

– Restaurant ceiling, sauna, swimming pool etc. - - The ceiling frequently exposed to moisture and cooling is not covered. – e.g. The pipe installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently. - The place where the pipe is installed is highly humid due to the lack of ventilation system.

Step 13 Checking the earthing

If the power distribution circuit does not have a earthing or the earthing does not comply with specifications, an earthing electrode must be installed. The corresponding accessories are not supplied with the air conditioner.

1 Select an earthing electrode that complies with the specifications given in the illustration. 2 Connect the flexible hose to the flexible hose port.

• In damp hard soil rather than loose sandy or gravel soil that has a higher earthing resistance.
• Away from underground structures or facilities, such as gas pipes, water pipes, telephone lines and underground cables.
• At least two metres away from a lightening conductor earthing electrode and its cable.

NOTE

- The earthing wire for the telephone line cannot be used to ground the air conditioner.

3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit. 4 Install a green/yellow coloured earthing wire:

• If the earthing wire is too short, connect an extension lead in a mechanical way and wrap it with insulating tape (do not bury the connection).
• Secure the earthing wire in position with staples.

NOTE

• If the earthing electrode is installed in an area with heavy traffic, its wire must be connected securely. 5 Carefully check the installation by measuring the earthing resistance with an earth resistance tester. If the resistance is above the required level, drive the electrode deeper into the ground or increase the number of earthing electrodes. 6 Connect the earthing wire to the electrical component box inside the outdoor unit.

Step 14 Performing final check and trial operation

1 Check the power supply between the outdoor unit and the auxiliary circuit breaker.

• 1 phase power supply : L, N • 3 phase power supply : R, S, T, N

2 Check the indoor unit.

a Check that you have connected the power and communication cables correctly. (If the power cable and communication cables are mixed up or connected incorrectly, the PCB will be damaged.) b Check that the thermistor sensor, drain pump/hose, and display are connected correctly.

3 Press K2 on the outdoor unit PCB to run the test mode and stop.

Pumping down refrigerant

WARNING

- After installing the product, be sure to perform leak tests on the piping connections. After pumping down refrigerant to inspect or relocate the outdoor unit, be sure to stop the compressor and then remove the connected pipes.

- Do not operate the compressor while a valve is open due to refrigerant leakage from a pipe or an unconnected or incorrectly connected pipe. Failure to do so may cause air to flow into the compressor and too high a pressure to develop inside the refrigerant circuit, leading to an explosion or product malfunction.

Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit. This operation must be carried out before disconnecting the refrigerant pipe in order to avoid refrigerant loss to the atmosphere.

1 Turn the system on in cooling with fan operating at high velocity and then let the compressor run for more than 5 minutes. (Compressor will immediately start, provided 3 minutes have elapsed since the last stop.) 2 Release the valve caps on High and Low pressure side. 3 Use L-wrench to close the valve on the high pressure side. 4 After approximately 2 minutes, close the valve on the low pressure side. 5 Stop operation of the air conditioner by pressing the (Power) button on the indoor unit or remote control. 6 Disconnect the pipes. - AC024TXADKC

- AC036/048TXADKC

Relocating the indoor and outdoor units

1 Pump down refrigerant. See Pumping down refrigerant on page 25. 2 Remove the power cord. 3 Disconnect the assembly cable from the indoor and outdoor units. 4 Remove the flare nuts connecting the indoor units and the pipes. At this time, cover the pipes of the indoor unit and the other pipes using a cap or vinyl plug to avoid foreign material entering. 5 Disconnect the pipes connected to the outdoor units. At this time, cover the valve of the outdoor units and the other pipes using a cap or vinyl plug to avoid foreign material entering.

Note: Make sure you do not bend the connection pipes in the middle and store together with the cables.

6 Move the indoor and outdoor units to a new location. 7 Remove the mounting plate for the indoor unit and move it to a new location.

Using the stop valve

Opening the stop valve

1 Open the cap and turn the stop valve anticlockwise by using a hexagonal wrench. 2 Turn it until the axis is stopped.

3 Tighten the cap securely.

Outer Diameter (mm)	Tightening torque
	Body cap (N·m)	Charging port cap (N·m)
∅6.35	20 to 25	10 to 12
∅9.52	20 to 25
∅12.70	25 to 30
∅15.88	30 to 35
Over ∅19.05	35 to 40

(1 N·m = 10 kgf·cm)

NOTE

• Do not apply excessive force to the stop valve and always use special tools. Otherwise, the valve box can be damaged and the back sheet can leak.
• If the watertight sheet leaks, turn the axis back by half, tighten the valve box, then check the leakage again. If there is no leakage any more, tighten the axis entirely.

Closing the stop valve

1. Remove the cap. 2. Turn the stop valve clockwise using a hexagonal wrench. 3. Tighten the axis until the valve reaches the sealing point. 4. Tighten the cap securely.

CAUTION

• When using the service port, always use a charging hose as well.
• Check for refrigerant gas leakage after tightening the cap.
• Always use a spanner and wrench when opening or tightening the stop valve.
