4.4.2 Making and Mounting Condensate Pipes
Procedure:
Install the
indoor units
4.4.3 Slope and Supporter of Condensate Pipe
The slope condensate pipe should be more than 1/100
The length of condensate pipe should be as short as possible to discharge the conden-
sate water (no air pocket on the way).
For a long condensate pipe, you may use a suspension bolt, to ensure the slope is 1/100
(the PVC pipe cannot be bent)
The space of the horizontal pipe support is as follows:
Grade
Hard PVC pipe
The length of horizontal pipe should be as short as possible.
4.4.4 Condensate Pipe Trap
When the unit can generate mins pressure at the
condensate water outlet of the unit, the water
trap should be installed (to prevent the stench
coming into the indoor units)
The water trap should be installed as shown
in the right diagram.
Each unit can have only one water trap.
The water trap installed should be easy to maintain.
