4.3 Drainage Pipe Installation and Drainage System Testing
4.3.1 Notice for Installation of Drain Pipe
(1) It is not allowed to connect the condensate drain pipe into waste pipe or other pipelines which
are likely to produce corrosive or peculiar smell to prevent the smell from entering indoors or
corrupt the unit.
(2) It is not allowed to connect the condensate drain pipe into rain pipe to prevent rain water from
pouring in and cause property loss or personal injury.
(3) Condensate drain pipe should be connected into special drain system for air conditioner.
(4) The drainage pipe should be short and the gradient downwards should be at least 1%~2% in
order to drain condensation water smoothly.
(5) The diameter of drainage hose should be bigger or equal to the diameter of drainage pipe joint.
(6) Install drainage pipe according to the following Fig.4.3.1 and arrange insulation to the drainage
pipe. Improper installation may lead to water leakage and damp the furniture and other things in
the room.
(7) You can buy normal hard PVC pipe used as the drainage pipe. During connection, insert the
end of PVC pipe into the drainage hole and then tighten it with drainage hole and wire binder.
Can’t connect the drainage hole and drainage hole with glue.
(8) When the drainage pipelines are used for several units, the position of pipeline should be about
100mm lower than the drainage port of each unit. In this case, thicker pipes should be applied.
