(2) Slope of twinning pipes
Make sure the slope of the twinning pipes are at an angle
within ±15˚ to the horizontal plane.
If the slope exceeds the specified angle, the unit may be
damaged.
(3) The length of the straight pipe between indoor units and the twinning pipe
Use the pipes supplied in the twinning kit, and make sure the section of the field-supplied pipe that connects to the twinning pipe has
at least 500 mm [19-11/16 in] of straight section. (The section of the field-supplied pipe that connects to the twinning pipe must have
at least 500 mm [19-11/16 in] of straight section.) If the straight section is less than 500 mm [19-11/16 in], it may result in equipment
damage.
(4) Pipe connection
• Make sure the pipes from the twinning pipe to the outdoor unit are sloped downwards.

• If twinning pipe is installed above the base of the outdoor unit,
it should be no more than 200 mm [7-7/8 in].
• If the length of the pipe between the branching point and the outdoor unit exceeds 2 m (6 ft), provide a trap within 2 m (6 ft) from the
branching point.
The trap must be at least 200 mm (7-7/8 in) in height. (low-pressure pipe only) If there is no trap, oil can accumulate inside the pipe,
causing a shortage of oil and may damage the compressor.
* Small dots in the figures indicate branching points.
