Condensate Drain Pipework
Condensate Pump
IMPORTANT Use only 10mm (3/8”) copper tube when connecting the discharge stub to the
condensate pump. The discharge line from the pump should rise no more than 6m
vertically and no more than 8m in total length before being interrupted with a swan
neck air break and tundish.
When calculating the total head required and factor into the drain pipework design.
Suitable roding positions should be incorporated particularly if the run is long.

Humidifier
(Optional Extra) All drain trays are fitted with their own trap assembly.
Condensate drain may be run to waste via ordinary plastic waste pipe.
Humidifier drain may be run to waste via pipe suitable for liquid temperatures of 100°C.
All drain pipework operating under gravity should be sloped away from the equipment and
the gradient should be made as steep as possible.
Suitable roding positions should be incorporated particularly if the run is long.

Performance
The following graphs illustrate the TOTAL static (head) pressure available. The system
horizontal pipe losses and vertical lift should be factored in when calculating the
condensate pump performance.

Water Leak Detector Tape The water detector tape should be insulated at the ends. This will avoid nuisance
alarms should un-insulated ends touch any conductive material.
