 Adopt suitable pipe diameter
 Adopt nearby condensate water discharge
12.5.2 Key points of drainage water pipe
installation
1. Considering the pipeline route and
elevation
 Before installing condensate water pipeline,
determine its route and elevation to avoid
intersection with other pipelines and ensure
slope is straight.
2. Drainage pipe selection
 The drainage pipe diameter shall not small
than the drain hose of indoor unit
 According to the water flowrate and
drainage pipe slope to choose the suitable
pipe, the water flowrate is decided by the
capacity of indoor unit.

capacity of indoor unit

3. Individual design of drainage pipe
system
 The drainage pipe of air conditioner shall
be installed separately with other sewage
pipe, rainwater pipe and drainage pipe in
building.
 The drainage pipe of the indoor unit with
water pump should be apart from the one
without water pump.
4. Supporter gap of drainage pipe
 In general, the supporter gap of the
drainage pipe horizontal pipe and vertical
pipe is respectively 1m~1.5m (3.28~4.92ft)
and 1.5m~2.0m(4.95~6.56ft).
 Each vertical pipe shall be equipped with
not less than two hangers.
 Overlarge hanger gap for horizontal pipe
shall create bending, thus leading to air
block.
Too long distance
Gas bag
5. The horizontal pipe layout should avoid
converse flow or bad flow
