Description
The Eckerle condensate delivery pump
EE 1650
M
is intended as a compact unit for the delivery of condensate
produced by air conditioning systems. The condensate is guided into
the integrated plastic tank and fully automatically pumped away. The
pump is controlled by an electronic float switch control system with a
separate overf low protection (potential-free relay with load capacity up
to 8A (ohmic load)).
Equipment of the EE 1650
M
2L condensate tanks with a height of 83 mm
Application of the EE 1650
M
Condensate delivery system for small and medium air conditioning
installations. For this field of application, use of a low-noise pump is of
major significance.
Field of application up to 35 kW cooling output.
Safety equipment
The delivery system is equipped with 2 separately operating float
switches. The working float switch activates and deactivates the pump
depending on the level of liquid (with run-on time). The alarm float
switch throws over the switch contact via the potential-free relay. For
more details, see the connection example of the potential-free relay.
We reco-
mmend connecting the air conditioning unit via the potential-free
relay in order to achieve a greater degree of operating liability, with
contactor depending on load.

Commissioning, mounting and installation
The condensate delivery pump can be
commissioned in a few simple stages:
There is an opening pre-punched on the inside of the lid (40 mm)
through which the condensate is passed by means of a pipe (nominal
width 40 mm) or hose to the inside. The supply line must be installed
sloping downwards towards the tank.
Position the lid on the container, ensuring that the suction hose with
filter is positioned in accordance with the diagram.
Now connect the delivery side PVC hose
(6 mm nominal width) to the hose nipple.
By drilling a hole of around 10 mm in diameter in the area of the dip in the
condensate tray, it is possible to also position the device in a tray integrat-
ed in the air conditioning unit. Before drilling, remove the lid of the tray.
During operation, steps must be taken to ensure that no liquid runs
over the pump. Please also observe the switching points.
Connect the potential-free relay.
Observe the admissible delivery height in the output diagram.
The mains plug is connected last. The pump must be connected to a
separate power source (230 V/50 Hz).
The pump must be positioned horizontally when mounting, as otherwise
the impairment to the correct function of the float switches can result.
On initial commissioning, the pump must be vented by lifting the lid.
See the instructions on the lid.
Check the function of the pump.
Note!
Do not use the pumps in the open air, only in enclosed buildings.
The pump features a run-on time, i.e. when the working float switch has
reached its bottom-most position again, the pump only switches off
after 30–50 seconds. During this period, the pump tank is pumped off
to a lower water level.
Maintenance EE 1650
M
Maintenance is restricted to a check of the suction filter and possible
dirt deposits in the tray. We recommend performing this check once a
year, and where applicable cleaning the suction filter and condensate
tray.
Safety remark:
During maintenance work, the pumps must
always be switched off by pulling out the mains plug. Please note: there
may still be voltage active at the potential-free relay.
