General Information
Grouped Drain
Piping
1. It is standard work practice to make connections to the main pipe from above. The pipe down
from the combination should be as large as possible.
2. The pipework should be kept as short as possible and the number of indoor units per group kept
to a minimum.
Use of an
Auxiliary Drain
Hose (Flexible)
If a drain pan made of polystyrene foam is used then an auxiliary drain hose (flexible) is also
essential. A flexible drain hose permits the drain socket and drain pipe to be connected without
difficulty and prevents any undue strain being placed on the drain pan.
Important points
1. The drain pipe should be at least equal in size to that of the indoor unit.
2. The drain pipe is thermally insulated to prevent the formation of condensation inside the pipe.
3. The drain up mechanism should be fitted before the indoor unit is installed and when the
electricity has been connected some water should be added to the drain pan and the drain
pump checked to see that it is functioning correctly.
4. All connections should be secure. (Special care is needed with PVC pipe)
The use of a colored adhesive with PVC pipes will help you to remember to connect them up.)
