Drain Pipe Work (Indoor)
Operational steps
Drain Pipe
Gradient and
Support
a) The drain pipe must be fitted at a gradient of at least 1/100.
The drain pipe should be as short as possible and free from airlocks.
b) Suspension bolts should be used to support long stretches of drain pipe in order to ensure that
a gradient of 1/100 is maintained. (PVC pipes should not be bent)
Spacing of supports for horizontal piping
c) The length of pipe laid horizontally should be kept to a minimum.
Drain Trap
Fit any indoor unit whose drain pipe connection is subjected to negative pressure, with a drain trap.
(FXMQ30~48M only)
a) Rig the drain trap as shown in the drawing bellow.
b) Provide one trap per unit. A single trap for converging units will prove ineffective.
c) Rig the trap to allow for future cleaning.
