5.5 Condensate drain connections
All units are fitted with a condensate collection tray at the base of the finned air handling coil for the purpose of
collecting the condensate that forms during normal operation in cooling mode.
Units operating in heat pump mode also have a condensate collection tray situated at the base of the source finned
coil for the purpose of collecting the condensate that forms during operation in heating mode and the water that forms
from frost during the defrost cycles.
The condensate collection trays are provided with a hose for conveying the water that is generated.
5.5.1 Condensate drain of the internal air coil
The condensate collection tray is provided with a male R 1" threaded pipe for connection.
Fig. 9 Connection to the condensate collection tray
The discharge pipe must always have a syphon at least 100 mm deep to prevent outside air from being sucked in
through it.
It is good practice to make a syphon straight after the connection to the tray.
The pipe draining the condensate must never be connected to waste water drains or run-off water drains, only to
rainwater systems to prevent any foul smelling gases from being sucked back.
5.5.2 Condensate drain of the external air coil
The condensate collection tray is provided with a male R 3/4" threaded pipe for connection.
Fig. 10 Connection to the condensate collection tray
The condensate drain of the external air coil can be left free.
Any condensate pipework connected to the unit must be protected from freezing.
