6.3.1 About connecting the refrigerant piping

Before connecting the refrigerant piping

Make sure the outdoor and indoor unit are mounted.

Typical workflow

Connecting the refrigerant piping involves:

▪ Connecting the refrigerant piping to the outdoor unit

▪ Connecting the refrigerant piping to the indoor unit

▪ Insulating the refrigerant piping

▪ Keeping in mind the guidelines for:

▪ Pipe bending

▪ Flaring pipe ends

▪ Brazing

▪ Using the stop valves

6.3.2 Precautions when connecting the refrigerant piping

INFORMATION

Also read the precautions and requirements in the following chapters:

▪ General safety precautions

▪ Preparation

DANGER: RISK OF BURNING

Unit Installation period Protection method

Outdoor unit >1month Pinch the pipe

<1month Pinch or tape the pipe

Indoor unit Regardless of the

period

INFORMATION

Do NOT open the refrigerant stop valve before checking the refrigerant piping. When you need to charge additional refrigerant it is recommended to open the refrigerant stop valve after charging.

6.3.3 Guidelines when connecting the refrigerant piping

Take the following guidelines into account when connecting pipes:

▪ Coat the flare inner surface with ether oil or ester oil when

connecting a flare nut. Tighten 3 or 4 turns by hand, before tightening firmly.

▪ Always use 2 wrenches together when loosening a flare nut.

▪ Always use a spanner and torque wrench together to tighten the

flare nut when connecting the piping. This to prevent nut cracking and leaks.

CAUTION

▪ Do NOT use mineral oil on flared part.

▪ NEVER install a drier to this unit to guarantee its

lifetime. The drying material may dissolve and damage the system.

NOTICE

Take the following precautions on refrigerant piping into account:

▪ Avoid anything but the designated refrigerant to get

mixed into the refrigerant cycle (e.g. air).

▪ Only use R32 or R410A2 when adding refrigerant.

▪ Only use installation tools (e.g. manifold gauge set) that

are exclusively used for R32 or R410A2 installations to withstand the pressure and to prevent foreign materials (e.g. mineral oils and moisture) from mixing into the system.

▪ Install the piping so that the flare is NOT subjected to

mechanical stress.

▪ Protect the piping as described in the following table to

prevent dirt, liquid or dust from entering the piping.

▪ Use caution when passing copper tubes through walls

(see figure below).

6.3.5 To flare the pipe end

CAUTION

▪ Incomplete flaring may cause refrigerant gas leakage.

▪ Do NOT re-use flares. Use new flares to prevent

refrigerant gas leakage.

▪ Use flare nuts that are included with the unit. Using

different flare nuts may cause refrigerant gas leakage.

1 Cut the pipe end with a pipe cutter. 2 Remove burrs with the cut surface facing down so that the

chips do not enter the pipe.

a Cut exactly at right angles.

b Remove burrs.

3 Remove the flare nut from the stop valve and put the flare nut

on the pipe.

4 Flare the pipe. Set exactly at the position as shown in the

following illustration.

5 Check that the flaring is properly made.

a Flare’s inner surface must be flawless.

b The pipe end must be evenly flared in a perfect circle.

c Make sure the flare nut is fitted.

6.3.6 To braze the pipe end

The indoor unit and outdoor unit have flare connections. Connect both ends without brazing. If brazing should be needed, take the following into account:

▪ When brazing, blow through with nitrogen to prevent creation of

large quantities of oxidised film on the inside of the piping. This film adversely affects valves and compressors in the refrigerating system and prevents proper operation.

▪ Set the nitrogen pressure to 20kPa (0.2 bar) (just enough so it

can be felt on the skin) with a pressure-reducing valve.

▪ Do NOT use flux when brazing copper-to-copper refrigerant

piping. Use phosphor copper brazing filler alloy (BCuP), which does not require flux. Flux has an extremely harmful influence on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will deteriorate the refrigerant oil.

6.3.7 To connect the refrigerant piping to the indoor unit

WARNING: FLAMMABLE MATERIAL

The R32 refrigerant (if applicable) in this unit is mildly flammable.

▪ Pipe length. Keep refrigerant piping as short as possible. ▪ Flare connections. Connect refrigerant piping to the unit using

flare connections.

▪ Insulation. Insulate the refrigerant piping on the indoor unit as

follows:

A Gas piping B Liquid piping

a Insulation material (field supply) b Cable tie (accessory) c Insulation pieces: Large (gas pipe), small (liquid pipe)

(accessories)

d Flare nut (attached to the unit) e Refrigerant pipe connection (attached to the unit)

f Unit

g Sealing pads: Medium 1 (gas pipe), medium 2 (liquid pipe)

(accessories)

1 Turn up the seams of the insulation pieces. 2 Attach to the base of the unit. 3 Tighten the cable ties on the insulation pieces. 4 Wrap the sealing pad from the base of the unit to the top of

the flare nut.

NOTICE

Make sure to insulate all refrigerant piping. Any exposed piping might cause condensation.

interface to ensure the best possible performance.

CAUTION

WARNING

Do not place a flammable spray bottle near the air conditioner and do not use sprays. Doing so may result in a fire.

Observe the following precautions to ensure the system operates properly.

▪ Prevent direct sunlight from entering a room during cooling

operation by using curtains or blinds.

▪ Ventilate often. Extended use requires special attention to

ventilation.

▪ Keep doors and windows closed. If the doors and windows remain

open, air will flow out of your room causing a decrease in the cooling or heating effect.

▪ Be careful not to cool or heat too much. To save energy, keep the

temperature setting at a moderate level.

▪ Never place objects near the air inlet or the air outlet of the unit. It

may cause deterioration in the effect or stop the operation.

▪ Turn off the main power supply switch to the unit when the unit is

not used for longer periods of time. If the switch is on, it consumes electricity. Before restarting the unit, turn on the main power supply switch 6 hours before operation to ensure smooth running.

▪ When the display shows (time to clean the air filter), clean the

filters (see "17.2.2To clean the air filter"on page26).

▪ Condensation may form if the humidity is above 80% or if the

drain outlet gets blocked.

▪ Adjust the room temperature properly for a comfortable

environment. Avoid excessive heating or cooling. Notice that it may take some time for the room temperature to reach the set temperature. Consider using the timer setting options.

▪ Adjust the air flow direction to avoid cool air from gathering on the

floor or warm air against the ceiling. (Up during cooling or dry operation to the ceiling and down during heating operation.)

▪ Avoid direct air flow to room inhabitants.

16 Energy saving and optimum

operation

CAUTION

Never expose little children, plants or animals directly to the air flow.

17 Maintenance and service

17.1 Overview: Maintenance and service

The installer has to perform a yearly maintenance.

About the refrigerant

This product contains fluorinated greenhouse gases. Do NOT vent gases into the atmosphere.

Refrigerant type: R32

Global warming potential (GWP) value: 675

Refrigerant type: R410A

Global warming potential (GWP) value: 2087.5

Installer and user reference guide

17 Maintenance and service

NOTICE

In Europe, the greenhouse gas emissions of the total refrigerant charge in the system (expressed as tonnes CO2-equivalent) is used to determine the maintenance intervals. Follow the applicable legislation.

Formula to calculate the greenhouse gas emissions:

GWP value of the refrigerant × Total refrigerant charge [in kg] / 1000

Please contact your installer for more information.

WARNING

R410A is a non-combustible refrigerant, and R32 is a mildly flammable refrigerant; they normally don’t leak. If the refrigerant leaks in the room and comes in contact with fire from a burner, a heater, or a cooker, this may result in a fire (in case of R32), or the formation of a harmful gas.

Turn off any combustible heating devices, ventilate the room, and contact the dealer from where you purchased the unit.

Do not use the unit until a service person confirms that the part from which the refrigerant leaked has been repaired.

WARNING

▪ Do NOT pierce or burn refrigerant cycle parts.

▪ Do NOT use cleaning materials or means to accelerate

the defrosting process other than those recommended by the manufacturer.

▪ Be aware that the refrigerant inside the system is

odourless.

NOTICE

Maintenance must be done by an authorised installer or service agent.

We recommend to do maintenance at least once a year. However, applicable legislation might require shorter maintenance intervals.

CAUTION

Before accessing terminal devices, make sure to interrupt all power supply.

DANGER: RISK OF ELECTROCUTION

To clean the air conditioner or air filter, be sure to stop operation and turn all power supplies off. Otherwise, an electric shock and injury may result.

18.1 Symptoms that are NOT system malfunctions

The following symptoms are NOT system malfunctions:

18.1.1 Symptom: The system does not operate

▪ The air conditioner does not start immediately after the ON/OFF

button on the user interface is pressed. If the operation lamp lights, the air conditioner is in normal condition. It does not restart immediately because one of its safety devices actuates to prevent the air conditioner from being overloaded. The air conditioner will turn on again automatically after 3minutes.

▪ The air conditioner does not start immediately after the power

supply is turned on. Wait 1 minute until the microcomputer is prepared for operation.

▪ The air conditioner does not restart immediately when the

temperature setting button is returned to its former position after pushing. It does not restart immediately because one of its safety devices actuates to prevent the air conditioner from being overloaded. The air conditioner will turn on again automatically after 3minutes.

▪ The outdoor unit has stopped. This is because the room

temperature has reached the set temperature. The unit switches to fan operation. " " (external control icon) is displayed on

the user interface and the actual operation is different from the user interface setting. For multi-split models, the microcomputer executes the following control depending on the operation mode of other indoor units.

▪ The fan speed is different from the setting. Pressing the fan speed

control button does not change the fan speed. When the room temperature reaches the set temperature in heating mode or the unit’s maximum capacity is reached, the outdoor unit will stop operation and the indoor unit will operate in fan only mode (low fan speed). In case of multi-split, the indoor unit alternately operates in fan stop mode and fan only mode (LL= low fan speed). This is to prevent the cool air from being blown directly onto anyone present in the room.

18.1.2 Symptom: Air blow direction is not as specified

Actual air blow direction is not as shown on the user interface. Automatic swing setting does not work.

Refer to the manual of the user interface.

18.1.3 Symptom: White mist comes out of a unit (Indoor unit)

▪ When humidity is high during cooling operation (in oily and dusty

places). If the interior of an indoor unit is extremely contaminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the interior of the indoor unit. Ask your dealer for details on cleaning the unit. This operation requires a qualified service person.

▪ When the air conditioner is changed over to heating operation

after defrost operation. Moisture generated by defrost becomes steam and exits.

18.1.4 Symptom: Noise of air conditioners (indoor unit)

▪ A "ringing" sound is heard after the unit is started. This sound is

generated by the temperature regulator working. It will quiet down after about a minute.

▪ A continuous low "hissing" sound is heard when the system is in

cooling or defrost operation. This is the sound of refrigerant gas flowing through both indoor and outdoor units.

▪ A hissing sound which is heard at the start or immediately after

stopping operation or defrost operation. This is the noise of refrigerant caused by flow stop or flow change.

▪ A "squeaking" sound is heard when the system is in operation or

after the stop of operation. Expansion and contraction of plastic parts caused by temperature change makes this noise.

18.1.5 Symptom: Dust comes out of the unit

When the unit is used for the first time in a long time. This is because dust has gotten into the unit.

18.1.6 Symptom: The units can give off odours

The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it again.

18.1.7 Symptom: The display shows "88"

This is the case immediately after the main power supply switch is turned on and means that the user interface is in normal condition. This continues for 1minute.

18.1.8 Symptom: The operation stopped suddenly (Operation lamp is on)

The air conditioner may stop for system protection due to large voltage fluctuation. It automatically resumes operation after about 3 minutes.

18.1.9 Symptom: The outdoor fan rotates while the air conditioner is not in operation

▪ After operation has stopped. The outdoor fan continues to

rotate for another 30 seconds for system protection.

▪ While the air conditioner is not in operation. When the outdoor

temperature is very high, the outdoor fan starts to rotate for system protection.

18.1.10 Symptom: The heating operation stops suddenly and a flowing sound is heard

The system is removing frost on the outdoor unit. You should wait for about 3 to 8minutes.
