6 Connecting the Drain Pipe

6.1 Installation of Drain Piping

Install the drain piping as shown in fi gure below and take measures against
condensation. Improperly rigged piping could lead to leaks and damage other
products.

6.2 Install the Drain Pipes

 Keep piping as short as possible and slope it downwards at a gradient of at
least 1/100 so that air may not remain trapped inside the pipe.
 Keep pipe size equal to or greater than that of the connecting pipe (PVC
pipe, nominal diameter 20mm/0.8in in, outside diameter 25mm/1in).
 Push the drain hose as far as possible over the drain socket, and tighten
the metal clamp securely.

 Insulate the drain hose inside the building.
 If the drain hose cannot be sufficiently set on a slope, fit the hose with
drain raising piping (field supplied).
 Make sure that heat insulation work is executed on the following 2 spots to
prevent any possible water leakage due to dew condensation.

 Connect the drain hose to the drain raising pipes and insulate them.
 Connect the drain hose to the drain outlet on the indoor unit and tighten it
with the clamp.
Precautions
 Install the drain raising pipes at a height of less than 530 mm /20.9 in.
 Install the drain raising pipes at a right angle to the indoor unit and no
more than 300 mm/11.8 in from the unit.
 To prevent air bubbles, install the drain hose level or slightly tilted up (<75
mm/3 in).
 The incline of drain hose should be 75 mm/3 in or less so that the drain
socket does not have to withstand additional force.
 To ensure a downward slope of 1:100, install hanging bars every 1m/3.3ft
to 1.5 m/4.9ft.
 When unifying multiple drain pipes, install the pipes as shown in figure 16.
Select converging drain pipes whose gauge is suitable for the operating
capacity of the unit.
