• If the length of suspension bolt is more than 1.5m, it is required to prevent vibration.
• If this is not possible, create an opening on the false ceiling in order to be able to use it to perform the required operations on the indoor unit.

Step 4 Purging inert gas from the indoor unit

The indoor unit comes with nitrogen gas (inert gas) charged at the factory. Therefore, all inert gas must be purged before connecting the assembly piping.

Unscrew the pinch pipe at the end of each refrigerant pipe.

Diagram description: Shows the indoor unit with refrigerant pipes and pinch pipes to be unscrewed.

Diagram description: Shows the indoor unit with refrigerant pipes, side cover, and pinch pipes.

? NOTE: To prevent dirt or foreign objects from getting into the pipes during installation, do not remove the pinch pipe completely until you are ready to connect the piping. The designs and shape are subject to change according to the model.

Step 5 Cutting and flaring the pipes

1 Make sure that you have the required tools available: pipe cutter, reamer, flaring tool, and pipe holder.

2 If you wish to shorten the pipes, cut them with a pipe cutter, ensuring that the cut edge remains at a 90° angle to the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.

Diagram description: Shows correct and incorrect pipe cuts: Correct (90° angle), Inclined, Damaged Surface, Cracked, Uneven Thickness.

Diagram description: Shows pipe cutting with a pipe cutter, and examples of pipe edges: Oblique, Rough, Burr.

3 To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer.

4 Slide a flare nut on to the pipe and modify the flare.

Diagram description: Shows a pipe with a flare nut, and a detailed view of the flare with dimensions: 90° ±2°, 45° ±2°, R 0.4 to 0.8 mm.

5 Check that the flaring is correct, referring to the illustrations below for examples of incorrect flaring.

Step 6 Connecting the assembly pipes to the refrigerant pipes

There are two refrigerant pipes of different diameters:

• A smaller one for the liquid refrigerant.
• A larger one for the gas refrigerant. The inside of copper pipe must be clean and has no dust.

1 Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque.

(1 N•m=10 kgf.cm)

Diagram description: Shows a spanner and torque wrench tightening a union with a flare nut. Illustrates the connection of pipes.

? NOTE: If the pipes must be shortened, see Step 5 Cutting and flaring the pipes on page 11.

• Tighten the nuts to the specified torques. If overtightened, the nuts could be broken so refrigerant may leak.
• Be sure to use an insulator thick enough to cover the refrigerant tube to protect the condensate water on the outside of the pipe falling onto the floor and to improve the efficiency of the unit.
• Cut off any excess foam insulation.
• Make sure that there are no cracks or waves on the bent area.
• It would be necessary to double the insulation thickness (10 mm or more) to prevent condensation even on the insulator when if the installed area is warm and humid.

❗ 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 4.2 MPa and for a burst pressure of at least 20.7 MPa. Copper pipe for hydro-sanitary applications is completely unsuitable.

• For sizing and limits (height difference, line length, max. bends, refrigerant charge, etc.) see the outdoor unit installation manual.
• All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it completely.
• If the pipes require brazing, make sure that oxygen free nitrogen (OFN) is flowing through the system. Nitrogen blowing pressure range is 0.02 to 0.05 MPa.

Step 7 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-32, it's responsible of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar (gauge).

LEAK TEST WITH R-32 (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-32.

Diagram description: Shows the AC052/071RNCDKG unit with a leak check point indicated on the refrigerant pipe.

Diagram description: Shows the AC100/120/140RNCDKG unit with a leak check point indicated on the refrigerant pipe.

? NOTE: The designs and shape are subject to change according to the model.

Step 8 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 Acrylonitrile Butadien Rubber separately around each refrigerant pipe.

Diagram description: Shows cross-sections of pipes with 'No gap' and 'NBR' labels, indicating proper insulation.

• Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight.
• Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe.
• Add the additional insulation if the insulation plate gets thinner.

Diagram description: Shows a hanger with refrigerant pipe insulation and additional insulation, with dimensions 'a' and 'a x 3'.

? NOTE: Always make the seam of pipes face upwards.

2 Wind insulating tape around the pipes and drain hose avoiding compressing the insulation too much.

Diagram description: Shows indoor unit with insulation cover pipe and insulation pipe, with a note to "Be sure to overlap the insulation".

❗ CAUTION: Be sure to wrap insulation tightly without any gaps.

3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit.

4 The pipes and electrical cables connecting the indoor unit with the outdoor unit must be fixed to the wall with suitable ducts.

❗ CAUTION: Make sure that all refrigerant connection must be accessible for easy maintenance and detachment.

• Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering.

5 Select the insulation of the refrigerant pipe.

• Insulate the gas side and liquid side pipe, noting the insulation thickness that must differ according to the pipe size.
• Standard: Less than an indoor temperature of 30°C, with humidity at 85%. If installing in a high humidity environment, use one grade thicker insulator by referring to the table below. If installing in an unfavourable environment, use thicker one.
• The heat-resistance temperature of the insulator must be more than 120°C.

Step 9 Installing the drain hose and drain pipe

Care must be taken when installing the drain hose for the indoor unit to ensure that any condensation water is correctly drained outside.

? NOTE:

• Installing the drain hose should be the shorter, the better.
• In order to discharge condensate water, a downward gradient should be maintained.
• Fix the drain hose with Cable-Tie, so that it will not separate from the machine.

Diagram description: Shows the indoor unit with a flexible hose clamp of the drain hose, joint of drain hose, drain hose, and wrap thermal sleeve hose. A-A' cross-section is shown.

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

<Geological condition>

High humidity locations such as shorelines, hot springs, lake or riversides, and ridges (when part of the building is covered by earth and sand)

<Operation purpose condition>

Restaurant ceiling, sauna, swimming pool etc.

<Building construction condition>

Ceilings frequently exposed to moisture and cooling are not covered. For example, pipes installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently.

Places (where the pipes are installed) that are highly humid due to a lack of ventilation.

1. Insert the drain hose to bottom of the outfall of water basin.
2. Lock flexible hose clamp of the drain hose according to the figure.
3. Wind and wrap flexible hose clamp and drain hose fully with thermal insulation sponge; fix both ends of external layer with ribbon for thermal insulation.
4. After being installed, drain hose must be insulated fully by heat insulating material. (To be provided at site.)

Emergency Temperature Output (ETO) function

❗ CAUTION: In order to deploy the ETO function, the MIM-B14, an external contact interface module, must be installed in each indoor unit.

• The ETO is a concept of emergency operation of indoor units. If the indoor unit 1 (main indoor unit) stops because of an error, the indoor unit 2 (sub indoor unit) starts to operate.
• Basically, the indoor unit 2 operates in the previous mode. [For the first time operation, it starts in 24 °C (75 °F) Auto mode.]
• To set more detailed operation conditions for the indoor unit 2, use the S-net Pro.

Setting up the ETO

Diagram description: Shows the connection between Main indoor unit, Sub indoor unit, and External contact interface module (MIM-B14), with communication lines (F1 and F2) and error output ports.

ETO operation specifications

1 Main indoor unit

• Based on the external contact control settings, the main indoor unit decides whether to generate output when an error (indoor unit stop) occurs.
• Based on the ETO settings, the main indoor unit decides whether to generate output according to the temperature and time conditions.

2 Sub indoor unit

• Based on the entrance control settings, the sub indoor unit decides the mode, set temperature, and fan speed when contact inputs are given.

Setting the indoor unit addresses

Option No. for an indoor unit address: 0AXXXX-1XXXXX-2XXXXX-3XXXXX

Before installing an indoor unit, be sure to set an address for the indoor unit by taking the following steps:

1. Make sure that the power is supplied to the indoor unit. If the indoor unit is not plugged in, it must include a power supply.

Diagram description: Shows an Indoor Unit with connection points.

2 Set an address for each indoor unit using the remote control, according to your air conditioning system plan, by referring to the following table and by following the steps in Common steps for setting the addresses and options on page 17.

• The indoor unit addresses (main and RMC addresses) are set to 0A0000-100000-200000-300000 by default.
• If indoor units and outdoor units match 1:1, you don't need to set the main address because it is automatically set by the outdoor unit.
• If you are using on or off controller, set RMC address.

❗ CAUTION: The main address must be set to a value in the range 0 to 15. If you set other values, communication error will occur.

• If any of SEG5 and SEG6 is set to a value in the range A to F, the main address of the indoor unit does not change.
• If SEG3 is set to 0, the indoor unit maintains the existing main address even if SEG6 is set to a new value.
• If SEG9 is set 0, the indoor unit maintains the existing RMC address even if SEG11 and SET12 are set to new values.

Setting an indoor unit installation option (suitable for the condition of each installation location)

Option No.: 02XXXX-1XXXXX-2XXXXX-3XXXXX

1 Make sure that the power is supplied to the indoor unit. If the indoor unit is not plugged in, it must include a power supply.

2 The panel(display) should be connected to an indoor unit to receive option.

3 Set the installation option according to the installation condition of an air conditioner.

• The default setting of an indoor unit installation option is "02000-100000-200000-300000".
• Individual control of a remote controller (SEG20) is the function that controls an indoor unit individually when there is more than one indoor unit.
• No need to assign SEG3, 6, 8, 9, 10, 11, 14, 22, 23, 24 which are non applicable. Even though those segments are set, they will be ignored.
• If you set the applicable segments with numbers other than the indiciated, the initial setting will be maintained.

4 Set the indoor unit option by wireless remote controller.

❗ CAUTION: SEG18 is applied in case of strong wind.

If you input a number other than 0~4 on the individual control of the indoor unit(SEG 20), the indoor is set as "Indoor 1".

Example) If you want to set as "Exterior temperature sensor: USE, External control: USE, Number of hours using filer: 2000hr",

assign option codes except SEG 1, 7,13,19 which are page options.

* Level control: The centralized controller can limit the functions and inputs of connected products with this function enabled. Example: Operation mode limit (Cooling only/Heating only/No limitation), Heating temperature upper limit, Cooling temperature lower limit) To enable 'Level control' when applying the DPM with the centralized controller, appoint the Main (Set 'Use of external control [SEG14] option to 4 or higher).

Example: When installing DPM (1 Outdoor unit with 4 indoor units)

Changing a particular option

You can change each digit of set option.

? NOTE: When changing a digit of an indoor unit address setting option, set the SEG3 as 'A'.

When changing a digit of indoor unit installation option, set the SEG3 as '2'.

Ex) When setting the 'buzzer control' into disuse status.
