Under no circumstances may pipes or tubes be inserted into the tank because this may lead to pump
failure since the integrated float switch may be blocked!
Standard condensing boilers are equipped with a siphon trap. This must in all cases be filled with water
prior to operation of the boiler and condensate pump. Failure to do so may result in acidic gases reaching the
pump and therefore destroying it!
4.2 Pressure connection
The pressure port is equipped with a check valve. PVC tubing with an inner diameter of 8 mm is to be tightly connected to
the pressure port, see Figure 3.
The PVC-tubing is to be secured with a hose clamp (not supplied) avoiding any kinks, ties, and connected to the drain
pipe of the sewer system. For installation use the adapter 50 mm/8 mm (see Figure 2).
In case of an installation in the basement below the level of backed-up water (locally defined; generally the upper edge of
the street) it must be ensured that the pressure piping is led above this level and then connected downward to the drain
pipe.
WARNING: In case of non-observance, the basement may be flooded in the event of flow back from
the sewer system!
4.3 Signalling cable
In addition to the power cord (POWER), the pump is also equipped with a signalling cable (ALARM). See Figure 4
Figure 4 - Cables
The signalling cable (dry contact) must be used to either conduct a safety shutdown of the condensing boiler (COM and
NC) or to activate an external low voltage alarm system (COM and NO). See Figure 5 for contact configuration. To avoid
water damages due to a defective pump this contact has to be contacted in any case, otherwise all kind of claims will
expire.
Please refer to the instruction manual of the condensing boiler for the connection as a safety
shutdown or to the manual of the alarm system for the connection as an alarm.
4.4 Test run
ATTENTION: Remove tape on top of the cover (see Figures 6,7 and 8)
The bolt for locking the float during transport is movable now and can be used as a test switch to start the motor without
water filling. This test should not exceed 2-3 seconds to avoid damages by dry running.
Remove bolt after test run and keep it for service and maintenance cases.
After finalised installation of inlet and outlet test the pump several times by water filling and check all hose connection
carefully.
