4.4.7 Key Points
The diameter of the condensate pipe should be more than or equal to that of the drainage pipe.
The condensate pipe should be insulated.
The lift pipe of the condensate pipe should be installed before the indoor unit. When the unit
is running, if there is water in the condenser collector, please check whether the condensate
pump is working properly.
All the connecting wiring should be solid (especially the PVC pipe).
4.4.6 Accessory Condensate Pipe (Hose)
If the condensate collector is made of polystyrene, it should use the hose. The condensate pipe
box can easily connect with the condensate pipe to prevent the condensate coil distorted
