(4) Connect the condensate hose (Figure 3-1-32).
2.2.6.2 Installing the Condensate Pipes
(1) For determining the position of the condensate hose, perform the following procedures.
(2) Insert the condensate pipe to the drain outlet of the unit and then tighten the clamp securely
with tape (Figure 3-1-33).
(3) Connect the extension condensate pipe to the condensate pipe and then tighten the
clamp with tape.

Tighten the clamp until the screw head is less than 4mm (1/8inch) from the hose (Figure 3-1-34).
- Metal clamp
Insulate the pipe clamp and the condensate hose using heat insulation sponge ( Figure 3-1-35).

Note: Step 1 to Step 3 have been finished by the manufacturer.
(4) When condensate hose requires extension, obtain an extension hose available commercially.
(5) After connecting the local condensate hose, tape the slits of the heat insulation tube.
(6) Connect the condensate hose to the local condensate pipe. Position the interconnecting wire
in the same direction as the piping.
2.2.6.3 Connecting the Condensate Hose
(1) Connect the extension auxiliary pipe to the local piping.
(2) Prepare the local piping at the connection point for the condensate pipe, as shown in the
installation drawings.
Note: Be sure to place the condensate hose as shown in the figure below, in a downward
sloping direction.
