14.4.4 To charge refrigerant: Flow chart

For more information, see "To charge refrigerant"[424].

Pre-charging refrigerant

Step 1

Calculate additional refrigerant charge amount: R (kg)

Refrigerant overcharge happened, recover

refrigerant to reach R=Q

Step 2

• Open valves C and B to the liquid line

• Execute pre-charging amount: Q (kg)

Step 3a

• Close valves C and B

• Charging is finished

• Fill in the amount on the additional

refrigerant charge label

• Go to test run

Step 3b

Close valves C and B

R=Q R>QR<Q

Troubleshooting 10
Symptom cool heat cannot be changed over 11
Symptom fan operation is possible but cooling and heating do not work 11
Symptom the fan direction does not correspond to the setting 11
Symptom the fan speed does not correspond to the setting 11
Symptom the system does not operate 11
Symptom the user interface reads u4 or u5 and stops but then restarts after a few minutes 11
Symptom white mist comes out of a unit indoor unit 11
Symptom white mist comes out of a unit indoor unit outdoor unit 11
Symptoms that are not system malfunctions 11
Troubleshooting 11
A continuous low hissing sound is heard when the system is in 12
A continuous low shah sound is heard when the system is in 12
A hissing sound which is heard at the start or immediately after 12
A low sah choro choro sound is heard while the indoor unit is 12
A pishi pishi squeaking sound is heard when the system stops 12
A zeen sound is heard immediately after the power supply is 12
About the box 12
After filling in this table please put it on the switch box cover 12
After heating operation expansion and contraction of plastic parts caused by temperature change make this noise 12
Be sure to fill out the blanks which are needed for after sale services 12
Calculation of additional refrigerant charging amount 12
Contact your dealer for removing and reinstalling the total unit moving units requires technical expertise 12
Cooling operation or at a stop when the drain pump optional accessories is in operation this noise is heard 12
Cooling or defrost operation this is the sound of refrigerant gas flowing through both indoor and outdoor units 12
Disposal 12
Do not try to dismantle the system yourself dismantling of the system treatment of the refrigerant oil and other parts must comply with applicable legislation units must be treated at a specialised treatment facility for reuse recycling and recovery 12
During operation the speed of the fan is controlled in order to optimise product operation 12
Economy for refrigerants one of the actions to achieve this is the reuse of reclaimed refrigerant in vrv units produced and sold in europe for more information about the countries that are in scope visit http www daikin eu loop by daikin 12
Environmental footprint with we want to create a circular 12
For details concerning piping selection and calculation or how to operate the leak detection function please refer to the installation manual 12
For the installer 12
Is part of daikin s wider commitment to reduce our 12
Make sure that all accessories are available in the unit 12
Notice 12
Record for settings contents see installation manual 12
Record of additional refrigerant charge amount and result of leak check operation 12
Record of indoor unit model and installation site 12
Relocation 12
Several different indoor units are being run on the same system when another unit is running some refrigerant will still flow through the unit 12
Stopped when another indoor unit is in operation this noise is heard in order to prevent oil and refrigerant from remaining in the system a small amount of refrigerant is kept flowing 12
Stopping operation or defrost operation this is the noise of refrigerant caused by flow stop or flow change 12
Symptom dust comes out of the unit 12
Symptom hot air can be felt when the indoor unit is stopped 12
Symptom noise of air conditioners indoor unit 12
Symptom noise of air conditioners indoor unit outdoor unit 12
Symptom noise of air conditioners outdoor unit 12
Symptom the compressor in the outdoor unit does not stop after a short heating operation 12
Symptom the display shows 88 12
Symptom the inside of an outdoor unit is warm even when the unit has stopped 12
Symptom the outdoor unit fan does not spin 12
Symptom the units can give off odours 12
The unit can absorb the smell of rooms furniture cigarettes etc and then emit it again 12
This is because the crankcase heater is warming the compressor so that the compressor can start smoothly 12
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 12
This is to prevent refrigerant from remaining in the compressor the unit will stop after 5 to 10 minutes 12
This unit uses hydrofluorocarbon contact your dealer when discarding this unit 12
To remove the accessories from the outdoor unit 12
Turned on the electronic expansion valve inside an indoor unit starts working and makes the noise its volume will reduce in about one minute 12
When the tone of operating noise changes this noise is caused by the change of frequency 12
When the unit is used for the first time in a long time this is because dust has gotten into the unit 12
