Design & installation Guide For McQuay MDS Multi System
4.4.8 Installation of the Drainage Lift Pipe
If the water collecting header is installed, please refer to the following:
After connecting, the hose should not be
higher than the connecting port. This can
prevent the water from flowing backwards.
Do not give external force to one side of the unit,
and the drainage pipe should not be loose and it
should be fixed.
If the drainage pipe needs to be lifted up, it
should be less than 300mm. If it is more than
500mm, maybe it will result in the refrigerant
leakage.
Use the gradienter to check if the indoor unit
is parallel to the ceiling,
