3. Individual design of drainage pipe system
•
The drainage pipe of air conditioner shall be in-
stalled 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 and 1.5m~2.0m.
•
Each vertical pipe shall be equipped with not less
than two hangers.
•
Overlarge hanger gap for horizontal pipe shall cre-
ate bending, thus leading to air block.
5. The horizontal pipe layout should avoid converse flow or
bad flow
•
The correct installation will not cause converse
water flow and the slope of the branch pipes can be
adjusted freely
•
The false installation will cause converse water flow
and the slope of the branch pipe can not be ad-
justed.
6. Water storage pipe setting
•
If the indoor unit has high extra static pressure and
without water pump to elevate the condensate wa-
ter, such as high extra static pressure duct unit , the
water storage pipe should be set to avoid converse
flow or blow water phenomena.
7. Lifting pipe setting of indoor unit with water pump
•
The length of lifting pipe should not exceed
750mm/29.5in.
•
The drainage pipe should be set down inclined after
the lifting pipe immediately to avoid wrong opera-
tion of water level switch.
•
Refer the following picture for installation reference.
8. Blowhole setting
•
For the concentrated drainage pipe system, there
should design a blowhole at the highest point of
main pipe to ensure the condensate water discharge
smoothly.
•
The air outlet shall face down to prevent dirt enter-
