Drain Piping Work
〈〈
Rig the drain pipe as shown below and take measures against condensation.
Improperly rigged piping could lead to leaks and eventually wet furniture and
belongings.
〉〉
〈〈
Insulate the drain hose inside the building.
〉〉
(1) Carry out the drain piping.
!
Keep piping as short as possible and slope it downwards so that air may not remained
trapped inside the pipe.
!
Keep pipe size equal to or greater than that of the connecting pipe (Vinyl pipe of 25 mm
nominal diameter and 32 mm outer diameter).
!
Use the attached drain hose and clamp.
Tighten the clamp firmly.
!
Insulate the clamp metal with the sealing pad.
!
There is negative pressure inside the unit relative to atmospheric pressure when
the unit is running, so be sure to provide drain flap on the drain outlet. (See the
figure)
!
In order to prevent foreign matter from building up inside the piping, you should
avoid curves as much as possible, and arrange so the trap can be cleaned.
Note:
!
If converging multiple drain pipes, install according to the procedure shown below. (Install a
drain trap for each indoor unit.)
!
A drain trap need not be installed.
!
The diameter of the piping is the same as that of the connecting pipe (PS1B), and should
be kept equal to or greater than that of the connecting pipe.
