4. Applications
The Conlift is designed for the pumping of
condensate from the following:
• boilers
• air-conditioning systems
• cooling and refrigeration systems
• air dehumidifiers
• evaporators.
The 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.
Warning
Condensates from boilers are aggressive
as they contain acid.
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.
The Conlift also has a safety overflow switch with a
1.7-metre electric cable. This overflow switch can be
connected to the condensate boiler and set to stop
the boiler in case of an alarm.
The 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.
English (GB)
Warning
Treat (possibly neutralise) condensate
from boilers according to local regulations
before it is led out into the sewage system.
Warning
The Conlift must not be used for flammable
liquids.
Warning
The Conlift must not be installed in
potentially explosive environments.
The 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 the 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 the Conlift, local
regulations may require the installation of a
neutralisation unit, even for pH values of 2.5 or
higher.

6.4 Operating mode
Caution
Note
English (GB)
The Conlift is designed for max. 60 starts
per hour.
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.
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
The Conlift must be installed according to
local regulations.
If not already integrated, a water trap (emission trap)
must be fitted in all inlets.
The Conlift is not designed for outdoor use.
7.1 Mechanical installation
See also the quick guide supplied with the Conlift.
When installing the 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, the condensate
source is switched off and an acoustic alarm is
generated.
Position 0: The condensate source is switched off
and an acoustic alarm is generated.
The Conlift1 can be retrofitted with the PCB which is
available as an accessory.
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.
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.
The power supply cable has a Schuko plug or a free
cable end. The cable has a length of 2 metres.
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 the
Conlift, make sure that the power supply
has been switched off and that it cannot be
accidentally switched on.
Warning
As a precaution, the 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.
The 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 the 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.
The 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
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. 1Wiring 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.
8. Startup

switch.
2. Continue filling water into the tank until the safety
overflow switch is activated. If no external alarm
is connected to the Conlift, this function can be
checked by means of a multimeter.
The safety overflow switch must be
activated before the water starts running
out of the Conlift.
3. Stop filling water into the tank and stop
TM 05 11 52 2211
squeezing the discharge hose. The alarm stops
(the switch opens). The pump continues
operating. When the stop level is reached, the
pump will stop.
After checking the function, push the inlet hose back
into the lifting station and let the condensate from the
boiler or air-conditioning system run into the tank
again.
