condensate pump InstRuctIons
Electrical connection
• Connect the pump to a power supply via an earth leakage circuit breaker according to the standard IEC 345.
For a power supply out of the A/C unit, you can use the option “M99209 - Power supply for condensate
pump”.
• Connect the lines of the alarm contact (black-black) to an alarm device (e.g. digital input on the controller).
When the water level is too high the contact is opened and an alarm is triggered.
The drain pipe must have an internal diameter of 10 mm.
• Connect a flexible plastic hose at the water outlet of the
pump.
• Consider the performance data of the pump according
to the diagram when installing the hose.
• Ensure that the hose is free of kinks and connect it to
the local sewage network.
Start-up
• Pour some water into the pump and check whether the pump is switch on and off.
• Pour continuously water into the pump until the alarm is triggered. In case of an alarm, the pump continues
operating, if it is still functional.
After the check, the pump is ready for operation.
