especially in the noise-sensitive spaces such as meeting rooms.
For connection of the flange plane, use non-flammable canvas adapter to prevent transmission of
vibration. For its size, see the indoor unit outline diagram. Use M6X20 screws (configured on site) for
connection.
All pipelines must be connected closely and soundly without leak of air. The pipelines must be
adiabatic and free from condensation.

2.5 Install the drainpipe
1. Install the indoor unit drainpipe
Install a drain stream trap in the drainpipe to prevent water from overflowing. (The drainpipeabsorbs
the odor. When the outside static pressure is high (especially the air inlet),it is difficult todrain the
water.)
Drainage should be natural. When constructing, the outside pipe of outdoor unit should be inclined
(1/50~1/100).
The bending part of drainpipe should be fewer than 2. Furthermore, to reduce the depositing dust,
avoid bending the pipe as possible as you can.
Make sure there is no dust or rubbish falling into indoor unit drain elbow and drainpipe.
After installation, remove the checking panel, pour some water in the drain elbow to see whether it
drains smoothly.
