6.5.2 Condensate drainage using a condensate pump
The water is drawn off by the condensate pump and discharged along a hose (supplied loose) connected on the pressure
side. Depending on conditions on site, the water can be discharged into drainage lines, possibly with a trap connection.
In the event of a fault with the condensate drain, the water level will continue to rise until the float switch triggers an alarm
contact. The contact can be analysed by external signalling devices.
We would recommend automatically terminating cooling operation, possibly with a shut-off valve, if the alarm contact is
triggered to prevent the condensate tray from overflowing.
Condensate drainage on site with a natural gradient
The further drainage of condensate from the condensate pump must be provided along a natural gradient with an ad-
equate cross-section (minimum 1/2"). Increase the cross-section of the line with longer condensate lines.
Check whether the condensate line needs to be insulated to prevent the build-up of condensate along the line.
Do not use a rigid transition to the on-site condensate drain, as this would reduce the delivery height of the pump. We
would recommend a free overflow into a trap.
Installation, cabling of the condensate pump
The condensate pump needs a separate power supply 230 V/50 Hz. We would generally advise against connecting it via the
room thermostat, as residual condensate could be produced after it has been switched off. Additional wires are needed to
analyse the alarm contact.
Use the following type of cable:
