Condensate pipes should be run in 15 mm o.d. hard plastic or copper tube and supported at 1.5 mêtre intervals - or
closer. It is important to avoid piping which can sag between supports, as this will create traps and prevent the water
running away. Drain pipes should be sloped downwards in the direction of flow and should fall at an angle of 2% or
steeper if possible. Condensate pipes MUST be insulated in order to prevent sweating and possible damage to ceiling
tiles.
The drain pipe should be run to a suitable drain or disposal tank with a pump.
If there is sufficient space above the ceiling, the condensate drain pipe may be raised to a position 500mm above the
ceiling surface in order to allow a greater fall (or longer length of pipe).
It is important to keep the length of this rising pipe as short as possible (near vertical) as the water inside it will run back
into the unit when the pump stops. If too much water is allowed to flow back there will be a problem of short-cycling of
the high level float switch.
Underceiling or ceiling
In case the drain pipe is connected to a tank with a pump, to avoid the water flow-back into the unit whrn the pump is
not working, the drain pipe should be 100mm above the ceiling surface.
In case ther are some obstacles to the line, please avoid to Ubend the the pipe (see figure below) otherways there
should be a condensing water stagnation.
We suggest to operate as figure below; it is to say to lower the pipe and let it continue in its course with the same
descent percentage.

◊ Air vent
To prevent the possibility of flooding do NOT fit an air vent in the drain pipe.
