Installation Instructions

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 the drain pipe short and sloping downwards at a gradient of at least
1/100 to prevent air from remaining trapped inside the pipe.
 Keep pipe size equal to or greater than that of the connecting pipe (PVC
pipe, nominal diameter 20mm/0.8in, outside diameter 25mm/1in).
 Push the drain hose as far as possible over the drain socket, and tighten
the metal clamp securely.

 Wrap the insulation (field supplied). over the metal clamp and drain hose
to insulate. See Figure 15.
 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.

Indoor drain pipe
—
Drain socket.

 Connect the drain hose to the drain raising pipes and insulate them.
 Connect the drain hose to the drain socket 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 to
reduce the force on the drain socket. See figure 16 for detail location.
 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 17.
Select converging drain pipes whose gauge is suitable for the operating
capacity of the unit.
