It would be the best choice to use the standard tube length to keep the basic quality of Room Air conditioner, for example cooling
and heating capacity, sound level, vibration level, and reliability.
But, according to a certain different installation condition, the connection tube length could be changed in the recommendation
length that is shown above.
In this case, installer should keep the installation condition to keep the quality of Room Air conditioner.
● Refrigerant should be charged additionally as written above according to the change of the length of the connection tube.
It needs to affect the decrease in cooling and heating capacity or of the reliability of compressor that may be caused by a lack of refriger-
ant.
● Installation position difference between the indoor unit and the outdoor unit should not exceed over than 15 meters.
● When the connection pipe is been extended longer than 5 meters, it might need to change the diameter of the electrical wire to a larger
● When the connection pipe is been extended longer than 5 meters, it might need to change the diameter of the electrical wire to a larger
size in order to keep a voltage drop for starting room air conditioner is not less than 85% of the rated voltage. And then, a voltage meter
will be useful to check the rate of the voltage drop.
