6. Drain Piping
1. The condensate pipe connection position is shown in figure 6.1.
2. Prepare a PVC pipe (Outer diameter: 1-17/64inch[32mm]).
3. Fix PVC pipe to the condensate pipe with the adhesion agent and clamps provided by the factories, the
downward slope of the condensate pipe is 1/25 - 1/100.
4. Perform the heat preservation work on the condensate pipe after it is connected.
