(FXUQ-MA) Drain Piping Work
1. Rig drain piping (Refer to Fig. 26)
As for drain work, perform piping in such a manner that water can be drained properly.
As for drain piping, the connection can be made from three different directions.
! Employ a pipe with either the same diameter or with the diameter larger (excluding the
raising section) than that of the connecting pipe (PVC pipe, nominal diameter 20 mm,
outside diameter 26 mm).
! Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent
air pockets from forming.
(Refer to Fig. 27)
Caution Water pooling in the drainage piping can cause the drain to clog.
! To keep the drain hose from sagging, space hanging wires every 1 to 1.5 m.
(Refer to Fig. 26)
! Use only the included drain hose (1), (for rightward running drain hose) or elbow (10) (for
upward running drain hose) and clamp (2).
! Fit the drain hose (1) or elbow (10) over the drain pipe up to the neck and fasten tight with
the clamp (2).
! Insulate the clamp (2) and drain hose or elbow (10) with the included sealing pad (8).
(Refer to Fig. 28)
! Make sure that heat insulation work is executed on the following 2 spots to prevent any
possible water leakage due to dew condensation.
! Insulate the drain hose inside the building.
! Drain socket
Caution ! Do not twist or bend the drain hose (1), so that excessive force is not applied to it, as this
could cause leaks.
! If converging multiple drain piping, install according to the procedure shown below.
(Refer to Fig. 29)
Select converging drain piping whose gauge is suitable for the operating capacity of the unit.
