2.2 Functional description

Alarm On
Pump On
Pump Off
The internal condensate pump KWL-KP-I has an internal sensor that automatically starts
the pump as soon as the water level rises above 5 mm. The internal sensor stops the
internal condensate pump KWL-KP-I as soon as the water level drops to approx. 5 mm.
An alarm relay will respond when the water level rises above approx. 25 mm. The pump
will run until the minimum water level is reached. The alarm is then reset.
3.1 Installation
The unit must be fully isolated from the mains power supply before all mainte-
nance and installation work and opening the terminal compartment! The electrical
connections must be carried out in accordance with the wiring diagrams and must
only be carried out by qualified electricians. The electrical connection must be fully
isolated until the final assembly!
Thoroughly rinse the condensate tray to remove all metallic particles and foreign objects
before placing the condensate pump KWL-KP-I in the condensate tray.
The condensate pump KWL-KP-I should never be operated "dry" without water.
1. Place the condensate pump KWL-KP-I flat and horizontally on the bottom of the
condensate tray, next to the drain connector.
2. For further noise reduction, ensure that the condensate pump KWL-KP-I is not
touching any condensate tray side walls. Use the hose or cable opening for this. The
condensate pump KWL-KP-I is equipped with anti-vibration feet to minimise the
associated noise level.
3. Connect the condensate hose to the condensate pump and plug it onto the inside of
the casing opening.
4. Also plug the condensate hose (provided by customer) onto the unit opening connec-
tor on the outside of the rear wall of the unit.
