4. Applications
Conlift is designed for the pumping of condensate
from the following:
• boilers
• air-conditioning systems
• cooling and refrigeration systems
• air dehumidifiers
• evaporators.
Conlift is suitable for the pumping of condensate
which is collected below sewer level or which cannot
flow to the sewage system or drain of the building by
means of a natural downward slope.
Conlift can pump condensates not requiring
neutralisation, i.e. with pH values of 2.5 or higher.
Condensates with pH values up to 2.5 should be
neutralised before they leave Conlift.
Boilers fired with the following fuels normally supply
condensate with pH values up to 2.5:
• gas
• liquid gas
• low-sulphur fuel oil according to DIN 51603-1.
Irrespective of the capability of Conlift, local
regulations may require the installation of a
neutralisation unit, even for pH values of 2.5 or
higher.
5. Function
The condensate runs by natural fall through a hose
into the tank. See section 7. Installation.
The liquid level in the tank is controlled automatically
by a float switch. A micro switch in the float switch
will start the pump when the liquid level reaches the
start level, and it will stop the pump again when the
liquid level has fallen to stop level. The condensate
is pumped through the discharge hose to the drain.
Conlift also has a safety overflow switch. This
overflow switch can be connected to the condensate
boiler and set to stop the boiler in case of an alarm.
Conlift has a thermal switch which stops the motor in
case of overload. When the motor has cooled to
normal temperature, it will restart automatically.
6. Operating conditions
6.1 Maximum head
5.5 metres.
6.2 Maximum flow rate
600 l/h.
6.3 Temperatures
6.3.1 Ambient temperature
During operation: +5 °C to +35 °C.
6.3.2 Liquid temperature
Average temperature: +50 °C.
6.4 Operating mode
S3 (intermittent operation): 30 % according to DIN
EN 0530 T1. This means that the system is running
for 18 seconds and is stopped for 42 seconds.
Warning
Condensates from boilers are aggressive
as they contain acid.
Warning
Treat (possibly neutralise) condensate
from boilers according to local regulations
before it is led out into the sewage system.
Warning
Conlift must not be used for flammable
liquids.
Warning
Conlift must not be installed in potentially
explosive environments.
Caution
Conlift is designed for max. 60 starts per
hour.

English (GB)

6.5 Handling of condensates
Condensates from condensate boilers are very
aggressive and will attack the material of the
building's sewage system.
In order to protect the sewage system, we
recommend the use of a neutralisation unit. The
neutralisation unit is included in Conlift2 pH+ and is
available as an accessory for Conlift1 and Conlift2.
See section 11. Accessories.
The local discharge regulations regarding
condensates from boilers must be met.
7. Installation
If not already integrated, a water trap (emission trap)
must be fitted in all inlets.
Conlift is not designed for outdoor use.
7.1 Mechanical installation
See also the quick guide supplied with Conlift.
When installing Conlift, observe the following:
• The condensate must run freely into the lifting
station.
• The cooling slots in the motor cover must not be
covered.
• The lifting station should be easily accessible in
order to facilitate maintenance.
• The lifting station must be installed in a
well-illuminated and -ventilated room.
• The lifting station is protected against splashing
water (in compliance with IP24).
7.1.1 Conlift2 and Conlift2 pH+
Conlift2 and Conlift2 pH+ incorporate a
printed-circuit board (PCB) enabling additional
functions when the level in the tank reaches the
alarm level.
The contact on the PCB can be set to two positions:
Position 1: The pump is started, and an acoustic
alarm is generated.
A: The alarm cable is not connected to the
condensate source or an external alarm. The
condensate source is not switched off.
B: The alarm cable is connected to the condensate
source or an external alarm. The condensate source
is switched off. See section 7.2.1 Cable to
condensate source or external alarm.
Position 2: The pump does not start, and an
acoustic alarm is generated.
A: The alarm cable is not connected to the
condensate source or an external alarm. The
condensate source is not switched off.
B: The alarm cable is connected to the condensate
source or an external alarm. The condensate source
is switched off. See section 7.2.1 Cable to
condensate source or external alarm.
Note
If Conlift is to be connected to a
pressure-reducing, observe the boiler
manufacturer's instructions.
Note
When cleaning heat exchangers and
burner units of boiler systems, make sure
that no acid and cleaning residuals enter
the condensing unit.
Note
Conlift must be installed according to local
regulations.

English (GB)

7.2 Electrical installation
Carry out the electrical connection according to local
regulations.
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
The power supply cable has a Schuko plug or a free
cable end. The cable has a length of 2 metres.
7.2.1 Cable to condensate source or external
alarm
Conlift has a safety overflow switch which can be
connected to the condensate source or to an
external alarm system. The switch is connected to an
1.7 metre alarm cable with free cable end.
Alarm systems with a control voltage of 250 VAC, 2.5
A, can be used.
On delivery, the alarm cable is connected to
terminals COM1 (brown) and NO4 (blue) of the
safety overflow switch. See fig. 1.
Fig. 1 Wiring diagram
The alarm cable can be connected in two ways,
depending on application:
• Shutdown of condensate source
The safety overflow switch can be connected to a
Class-II low-voltage circuit.
To enable shutdown of the condensate source,
the COM1 and NO4 terminals of the safety
overflow switch must be connected in series with
the low-voltage thermostat circuit of the
condensate source.
• External alarm system
The COM1 and NC2 terminals can be used to
close a low-voltage alarm circuit.
To activate an alarm, the COM1 and NC2
terminals of the safety overflow switch must be
connected in series with the low-voltage alarm
circuit.
Warning
Check that the installation has a 1 A
slow-blowing fuse on the mains side and
an earth leakage circuit breaker according
to IEC 345.
The breaking capacity of the fuse must not
exceed 1 A.
Warning
The power supply cable with a free cable
end must be connected by an authorised
electrician.
Warning
If the power supply cable is damaged, it
must be replaced by the manufacturer, the
manufacturer's service partner or similarly
qualified person.
Warning
Before starting work on or moving Conlift,
make sure that the power supply has been
switched off and that it cannot be
accidentally switched on.
Warning
As a precaution, Conlift must be connected
to a Schuko socket or socket with earth
connection.
We recommend to provide the permanent
installation with an earth leakage circuit
breaker (ELCB) with a tripping current < 30
mA.
Conlift must be connected to an external
mains switch with a minimum contact gap
of 3 mm in all poles.
Warning
Before starting work on Conlift, switch off
the power supply and make sure that it
cannot be accidentally switched on.
Work on electric systems and components
must only be carried out by an authorised
electrician.
