Installing an oil trap
Check the following list and install an oil trap.
Install an oil trap only when the outdoor unit is at a higher level than the indoor unit.
Based on cooling operation, install it on the gas side pipe only.
Install the oil trap only in between the outdoor unit and the rst branch joint and it should be installed at every 10 m.
Radius of curvature (R) on the oil trap are as follows;
Pipe diameter (D) 12.70 15.88 19.05 22.23 25.40 28.60 31.75
Radius of curvature (R) 25 and over 32 and over 38 and over 41 and over 51 and over 57 and over 60 and over
Height of the oil trap (H): 4R ≤ H ≤ 6R

• If the compressor operates in the condition that the refrigerant pipe is not installed correctly and the service
valve is opened, the refrigerant pipe may intake air and the pressure inside the refrigerant cycle will increase,
which may result in explosion and injury.
• Make a hole (10 mm in diameter) on the insulation so that rain water can be drained in case it gets inside of the
insulation. However, be careful not to damage the pipe.
