NOTICE
Make sure to open the stop valves after installing therefrigerant piping and performing vacuum drying. Runningthe system with the stop valves closed may break thecompressor.
5.4 Checking the refrigerant piping
5.4.1 About checking the refrigerant pipingRefrigerant piping works are finished?
The indoor units and/or outdoor unit were already powered ON?
Use procedure:"Method 2: After power ON".
Finish piping work.
Use procedure:"Method 1: Before power ON (regular method)".
Yes
No
No
Yes
It is very important that all refrigerant piping work is done before theunits (outdoor or indoor) are powered on.
When the units are powered on, the expansion valves will initialise.This means that they will close. Leak test and vacuum drying of fieldpiping and indoor units is impossible when this happens.
Therefore, there will be explained 2 methods for initial installation,leak test and vacuum drying.
Method 1: Before power ONIf the system has not yet been powered on, no special action isrequired to perform the leak test and the vacuum drying.
Method 2: After power ONIf the system has already been powered on, activate setting [2‑21](refer to "6.1.4 To access mode 1 or 2" on page 16). This settingwill open field expansion valves to guarantee a R410A pipingpathway and make it possible to perform the leak test and thevacuum drying.
NOTICE
Make sure that all indoor units connected to the outdoorunit are powered on.
NOTICE
Wait until the outdoor unit has finished the initialisation toapply setting [2‑21].
Leak test and vacuum dryingChecking the refrigerant piping involves:
▪ Checking for any leakages in the refrigerant piping.
▪ Performing vacuum drying to remove all moisture, air or nitrogenin the refrigerant piping.
If there is a possibility of moisture being present in the refrigerantpiping (for example, water may have entered the piping), first carryout the vacuum drying procedure below until all moisture has beenremoved.
All piping inside the unit has been factory tested for leaks.
Only field installed refrigerant piping needs to be checked.Therefore, make sure that all the outdoor unit stop valves are firmlyclosed before performing leak test or vacuum drying.
NOTICE
Make sure that all (field supplied) field piping valves areOPEN (not outdoor unit stop valves!) before you start leaktest and vacuuming.

For more information on the state of the valves, refer to"5.4.3 Checking refrigerant piping: Setup" on page 11.
5.4.2 Checking refrigerant piping: Generalguidelines
Connect the vacuum pump through a manifold to the service port ofall stop valves to increase efficiency (refer to "5.4.3 Checkingrefrigerant piping: Setup" on page 11).
NOTICE
Use a 2-stage vacuum pump with a non-return valve or asolenoid valve that can evacuate to a gauge pressure of–100.7 kPa (5 Torr absolute).
NOTICE
Make sure the pump oil does not flow oppositely into thesystem while the pump is not working.
NOTICE
Do not purge the air with refrigerants. Use a vacuum pumpto evacuate the installation.

NOTICE
The connections to the indoor units and all indoor unitsshould also be leak and vacuum tested. Keep any possible(field supplied) field piping valves open as well.
Refer to the indoor unit installation manual for more details.Leak test and vacuum drying should be done before thepower supply is set to the unit. If not, see also the flowchart earlier described in this chapter (see "5.4.1 Aboutchecking the refrigerant piping" on page 10).
5.4.4 To perform a leak testThe leak test must satisfy the specifications of EN378‑2.
To check for leaks: Vacuum leak test1 Evacuate the system from the liquid and gas piping to
–100.7 kPa (–1.007 bar/5 Torr) for more than 2 hours.
2 Once reached, turn off the vacuum pump and check that thepressure does not rise for at least 1 minute.
3 Should the pressure rise, the system may either containmoisture (see vacuum drying below) or have leaks.
To check for leaks: Pressure leak test1 Break the vacuum by pressurising with nitrogen gas to a
minimum gauge pressure of 0.2 MPa (2 bar). Never set thegauge pressure higher than the maximum operation pressure ofthe unit, i.e. 4.0 MPa (40 bar).
2 Test for leaks by applying a bubble test solution to all pipingconnections.
3 Discharge all nitrogen gas.
NOTICE
Make sure to use a recommended bubble test solutionfrom your wholesaler. Do not use soap water, which maycause cracking of flare nuts (soap water may contain salt,which absorbs moisture that will freeze when the pipinggets cold), and/or lead to corrosion of flared joints (soapwater may contain ammonia which causes a corrosiveeffect between the brass flare nut and the copper flare).
5.4.5 To perform vacuum dryingTo remove all moisture from the system, proceed as follows:
1 Evacuate the system for at least 2 hours to a target vacuum of–100.7 kPa (–1.007 bar/5 Torr).
2 Check that, with the vacuum pump turned off, the targetvacuum is maintained for at least 1 hour.
3 Should you fail to reach the target vacuum within 2 hours ormaintain the vacuum for 1 hour, the system may contain toomuch moisture. In that case, break the vacuum by pressurisingwith nitrogen gas to a gauge pressure of 0.05 MPa (0.5 bar)and repeat steps 1 to 3 until all moisture has been removed.
4 Depending on whether you want to immediately chargerefrigerant through the refrigerant charge port or first pre-chargea portion of refrigerant through the liquid line, either open theoutdoor unit stop valves, or keep them closed. See "5.6.3 Tocharge refrigerant" on page 12 for more information.
5.5 To insulate the refrigerant pipingAfter finishing the leak test and vacuum drying, the piping must beinsulated. Take into account the following points:
▪ Make sure to insulate the connection piping and refrigerant branchkits entirely.
▪ Be sure to insulate the liquid and gas piping (for all units).
▪ Use heat resistant polyethylene foam which can withstand atemperature of 70°C for liquid piping and polyethylene foam whichcan withstand a temperature of 120°C for gas piping.
▪ Reinforce the insulation on the refrigerant piping according to theinstallation environment.
Ambienttemperature
Humidity Minimum thickness
≤30°C 75% to 80% RH 15 mm>30°C ≥80% RH 20 mm
Condensation might form on the surface of the insulation.
▪ If there is a possibility that condensation on the stop valve mightdrip down into the indoor unit through gaps in the insulation andpiping because the outdoor unit is located higher than the indoorunit, this must be prevented by sealing up the connections. Seebelow figure.

5.6 Charging refrigerant
5.6.1 Precautions when charging refrigerant
WARNING
▪ Only use R410A as refrigerant. Other substances maycause explosions and accidents.
▪ R410A contains fluorinated greenhouse gases. Itsglobal warming potential (GWP) value is 2087.5. DoNOT vent these gases into the atmosphere.
▪ When charging refrigerant, always use protectivegloves and safety glasses.
NOTICE
If the power of some units is turned off, the chargingprocedure cannot be finished properly.
NOTICE
Be sure to turn on the power 6 hours before operation inorder to have power running to the crankcase heater andto protect the compressor.
NOTICE
If operation is performed within 12 minutes after the indoorand outdoor units are turned on, the compressor will notoperate before the communication is established in acorrect way between outdoor unit(s) and indoor units.
NOTICE
Before starting charging procedures, check if the 7‑LEDsdisplay is as normal (see "6.1.4 To access mode 1 or 2" onpage 16), and there is no malfunction code on the userinterface of the indoor unit. If a malfunction code ispresent, see "8.1 Solving problems based on errorcodes" on page 21.
NOTICE
Make sure all connected indoor units are recognised(setting [1‑5]).
NOTICE
Close the front panel before any refrigerant chargeoperation is executed. Without the front panel attached theunit cannot judge correctly whether it is operating properlyor not.
NOTICE
In case of maintenance and the system (outdoor unit+fieldpiping+indoor units) does not contain any refrigerant anymore (e.g., after refrigerant reclaim operation), the unit hasto be charged with its original amount of refrigerant (referto the nameplate on the unit) and the determined additionalrefrigerant amount.
5.6.2 To determine the additional refrigerantamount
INFORMATION
For final charge adjustment in a test laboratory, contactyour dealer.
Additional refrigerant to be charged=R (kg). R should be rounded offin units of 0.1 kg.
R=[(X1×Ø9.5)×0.059+(X2×Ø6.4)×0.022]
X1...2=Total length (m) of liquid piping size at Øa
INFORMATION
Piping length is considered the distance from the outdoorunit to the farthest indoor unit.
When using metric piping, please take into account following tableconcerning the weight factor to be allocated. It should be substitutedin the formula for R.
Inch piping Metric pipingSize (Ø) (mm) Weight factor Size (Ø) (mm) Weight factor
6.4 0.022 6 0.0189.5 0.059 10 0.065
5.6.3 To charge refrigerantTo speed up the refrigerant charging process, it is in case of largersystems recommended to first pre-charge a portion of refrigerantthrough the liquid line before proceeding with the manual charging. Itcan be skipped, but charging will take longer then.
Pre-charging refrigerantPre-charging can be done without compressor operation, byconnecting the refrigerant bottle to the service port of the liquid stopvalve.

14.2 Symptoms that are not airconditioner troubles
Following symptoms are not air conditioner troubles:
14.2.1 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 lamplights, the system is in normal condition. To prevent overloading of
the compressor motor, the air conditioner starts 5 minutes after itis turned ON again in case it was turned OFF just before. Thesame starting delay occurs after the operation mode selectorbutton was used.
▪ If "Under Centralized Control" is displayed on the user interface,pressing the operation button causes the display to blink for a fewseconds. The blinking display indicates that the user interfacecannot be used.
▪ The system does not start immediately after the power supply isturned on. Wait one minute until the micro computer is preparedfor operation.
14.2.2 Symptom: Fan operation is possible, butcooling and heating do not work
Immediately after the power is turned on. The micro computer isgetting ready to operate and is performing a communication checkwith all indoor units. Please wait 12 minutes (max.) till this process isfinished.
14.2.3 Symptom: The fan strength does notcorrespond to the setting
The fan speed does not change even if the fan speed adjustmentbutton in pressed. During heating operation, when the roomtemperature reaches the set temperature, the outdoor unit goes offand the indoor unit changes to whisper fan speed. This is to preventcold air blowing directly on occupants of the room. The fan speedwill not change even when another indoor unit is in heatingoperation, if the button is pressed.
14.2.4 Symptom: The fan direction does notcorrespond to the setting
The fan direction does not correspond with the user interfacedisplay. The fan direction does not swing. This is because the unit isbeing controlled by the micro computer.
14.2.5 Symptom: White mist comes out of a unit(Indoor unit)
▪ When humidity is high during cooling operation. If the interior of anindoor unit is extremely contaminated, the temperature distributioninside a room becomes uneven. It is necessary to clean theinterior of the indoor unit. Ask your dealer for details on cleaningthe unit. This operation requires a qualified service person.
▪ Immediately after the cooling operation stops and if the roomtemperature and humidity are low. This is because warmrefrigerant gas flows back into the indoor unit and generatessteam.
14.2.6 Symptom: White mist comes out of a unit(Indoor unit, outdoor unit)
When the system is changed over to heating operation after defrostoperation. Moisture generated by defrost becomes steam and isexhausted.
14.2.7 Symptom: The user interface displayreads "U4" or "U5" and stops, but thenrestarts after a few minutes
This is because the user interface is intercepting noise from electricappliances other than the air conditioner. The noise preventscommunication between the units, causing them to stop. Operationautomatically restarts when the noise ceases.

VRV IV-S system air conditioner4P399985-1D – 2016.03
14.2.8 Symptom: Noise of air conditioners(Indoor unit)
▪ A "zeen" sound is heard immediately after the power supply isturned on. The electronic expansion valve inside an indoor unitstarts working and makes the noise. Its volume will reduce inabout one minute.
▪ A continuous low "shah" sound is heard when the system is incooling operation or at a stop. When the drain pump (optionalaccessories) is in operation, this noise is heard.
▪ A "pishi-pishi" squeaking sound is heard when the system stopsafter heating operation. Expansion and contraction of plastic partscaused by temperature change make this noise.
▪ A low "sah", "choro-choro" sound is heard while the indoor unit isstopped. When another indoor unit is in operation, this noise isheard. In order to prevent oil and refrigerant from remaining in thesystem, a small amount of refrigerant is kept flowing.
14.2.9 Symptom: Noise of air conditioners(Indoor unit, outdoor unit)
▪ A continuous low hissing sound is heard when the system is incooling or defrost operation. This is the sound of refrigerant gasflowing through both indoor and outdoor units.
▪ A hissing sound which is heard at the start or immediately afterstopping operation or defrost operation. This is the noise ofrefrigerant caused by flow stop or flow change.
14.2.10 Symptom: Noise of air conditioners(Outdoor unit)
When the tone of operating noise changes. This noise is caused bythe change of frequency.
14.2.11 Symptom: Dust comes out of the unitWhen the unit is used for the first time in a long time. This isbecause dust has gotten into the unit.
14.2.12 Symptom: The units can give off odoursThe unit can absorb the smell of rooms, furniture, cigarettes, etc.,and then emit it again.
