Installation
Page 101
• 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.
• 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-
ing pipe.
• Each indoor unit of the system should be installed it.
• The installation should be considering the conve-
nience for future cleaning.
9. The end of drainage pipe shall not contact with ground
directly.
