It would be the best choice to use the standard tube length to keep the basic quality of Room Air conditioner, for ex -
ample 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 recom -
mendation 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 refrigerant.
▪
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 elec -
trical 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.
