Making the electrical connection
DANGER: Risk to life from electric shock!
Never open the condensate pump as long as it is
connected to the mains.
B All electrical work must be carried out by an
electrician.
B Before starting electrical work, isolate all poles and
secure against unintentional reconnection.
The following must be observed for the electrical connection:
• Make the electrical connection in accordance with the applicable
standards in the relevant country (Germany: VDE 0100).
• Observe the connection diagrams of all connected appliances and
accessories.
• Only use the electrical connection to the condensate pump to supply
power to the condensate pump.
• Check whether the earth resistance is lower than 38 Ω.
• Protect the condensate pump via an RCD with a rated response
current of not more than 30 mA.
• The condensate pump power plug must be easily accessible.
B Plug the condensate pump into an earthed socket.

Checking the function
Check the condensate pump for function at least once
per year.
Operational description
The condensate pump contains a pump. The condensate pump tank is
equipped with a float switch that controls the pump operation. The
pump starts as soon as condensate enters the condensate pump.
• The float switch turns the pump on and off.
If a fault indication system is connected:
• The fault indication system is triggered if there is an unusually high
water level.
What triggers the fault indication system varies
depending on the connection version installed
(
chapter 3.3, page 13).

• To protect the electronic switching components of the condensate
Checking the function of the pump and float switch
B Fill the condensate pump with water until the pump starts.
B Check whether water is pumped away when the pump is operational.
B Check whether the pump shuts down.
Checking the function of the fault indication system
B Fill with water until the fault indication is triggered.
B Check whether the fault indication system triggers the function of the

B Stop filling with water.
B Check whether water is pumped away when the pump is operational.
B Check whether the pump shuts down.
B Check whether the fault indication system reverts to standard

B All electrical work must be carried out by an
electrician.
B Before starting electrical work, isolate all poles and
secure against unintentional reconnection.
B Work on electrical components of the pump must only
be carried out by authorised customer service
personnel.
