2. General description

The Grundfos Conlift is a compact lifting station with
built-in non-return valve; it works automatically. The
Conlift is ready for installation.

2.1 Applications

The Conlift is designed for the pumping of conden­sate from

• 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
natural gravitation.

Condensates from boilers are aggressive.
They contain acid.

The Conlift can pump condensate with a pH value
equal to or above 2.7 from boilers with a heat output
of up to 200 kW.

This applies to boilers fired with

• gas

• liquid gas

• low-sulphur fuel oil according to DIN 51 603-1.

Note:

Where boilers are fired with the above fuels, but

• have a heat output above 200 kW,

• produce condensate with a pH value below 2.7,
and where boilers

• are fired with oils other than low-sulphur fuel oil,
the condensate from the boiler must be neutralised

before entering the sewage system/lifting station.

The Conlift must not be used for the trans­fer of inflammable liquids.

The Conlift must not be installed in poten­tially explosive environments.

In case of deviations from the application conditions
stated above, local electricity regulations and stand­ards must be observed.

In case of doubt, contact a qualified electrician.

4

3. Function

m

us

The condensate flows by natural gravitation through
a hose into the lifting station, see section 4. Installa-
tion.

When the liquid level in the collecting tank reaches
60 mm, the pump starts automatically via pressure
switch 1. When the liquid level falls below 35 mm,
the pump stops.

The condensate is pumped through the discharge
hose to the drain.

If the liquid level rises above 80 mm, the alarm
(buzzer) is activated via pressure switch 2 (alarm
pressure switch), and the pump starts (second cut­in).

accordance with local regulations.

• The condensate must flow freely into the lifting
station.

• The cooling slots in the motor cover must not be
covered.

• Easy access to the lifting station must be provided
to facilitate maintenance.

• The lifting station must be installed in a well-illumi­nated and -ventilated room.

• The lifting station must be protected against
splashing water (in compliance with IP X4).

4.3.1 Securing the Conlift

To prevent personal injury caused by
electric shock, scalding hot water or acid,
do not turn the Conlift upside down.

If the Conlift is installed in a room where there is a
risk of flooding, the angular mounting brackets must
be used. They counteract the buoyancy of the Conlift
(see figures 3 and 4), and thus prevent the collecting
tank from tilting and the spillage of acid.

In rooms where there is no risk of flooding, the angu­lar mounting brackets also prevent accidental

• overturning of the lifting station (floor mounting) or

• detachment of the lifting station from the wall (wall
mounting).

This prevents the acid in the collecting tank from
spilling out and causing damage.

Note:

• The Conlift must be mounted horizontally and se­cured by screws as shown in figures 3 and 4.

• The Conlift must be mounted in a dry and frost­free room with good ventilation.

• The angular mounting brackets counteract buoy­ancy, e.g. in connection with temporary flooding.

4.4 Connection of inlet and discharge

hoses

The hose supplied as an accessory can be used as
inlet and discharge hose.

• Attach the hose to the wall.

Distance between attachment points:
Approx. 30 cm.

• Make sure that the hose does not sag or is

squeezed.

• Avoid sharp bends. The bending radius of the

hose must be at least 60 mm.

• Run the inlet and discharge hoses in such a way

that they do not strain the Conlift.

4.4.1 Inlet hose

• When running the inlet hose from the boiler or

cooling/air-conditioning system to the Conlift,
make sure that the condensate flows freely into
the collecting tank.

• Insert the inlet hose sufficiently deep into the tank

through the inlet opening, see fig. 7. It is recom­mended to make a sloping cut to the hose.

4.4.2 Discharge hose

• Pass the discharge hose end over the discharge

stub (the grommet should not be lubricated with
grease), see fig. 7. Fasten the hose with the
clamp supplied with the lifting station.

• Take the discharge hose vertically up to the high-

est point from where the condensate can flow
freely into the sewage system or drain of the build­ing.

• If the Conlift is positioned below sewer level, the

hose must have a return loop at the highest point.
The lower edge of the loop must be 10 to 20 cm
above sewer level (the sewer level usually corre­sponds to the street level).

• At the highest point, a loop must be formed. The

bending radius of the hose must be at least
60 mm.

5. Electrical connection

The electrical connection must be carried out by a
qualified electrician in accordance with local regula­tions.

Before starting work on the Conlift or
moving the Conlift, the electricity supply
must be switched off. It must be ensured
that the electricity supply cannot be
accidentally switched on.

Note: Make sure that the supply voltage and fre­quency correspond to the values stated on the
nameplate.

As a precaution, the Conlift must be con­nected to a Schuko socket or a socket with
earth connection.
It is recommended to fit 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.

• Distance from the Conlift: 1 to 1.5 metres.

• The Schuko socket/socket with earth connection

and the boiler or cooling/air-conditioning system
must be connected to two different circuits. In
case of supply failure or undesired cut-out of the
cooling/air-conditioning system, this ensures that
the condensate, which continues to flow into the
collecting tank, is pumped away, thus causing no
damage.

• The Conlift incorporates a thermal switch, which

stops the motor in case of overload. When the mo­tor has cooled to normal temperature, it will restart
automatically.

As standard, the Conlift is fitted with an alarm device
(buzzer). It is also possible to pass on the alarm indi­cation via a potential-free contact.
See section 4.4.3 External alarm/potential-free con-
tact.

6. Start-up

Note: Start-up of the Conlift must be made in ac-

cordance with local regulations and accepted codes
of good practice.

1. Make sure that all hoses and connections are

tight.

2. Make sure that the motor cover (pos. 2) is

screwed on the Conlift, see section 8. Compo-
nents.

3. Switch on the electricity supply.

6.1 Checking the function

Pump operation:

Procedure:

1. Cut off the flow of condensate from the boiler or
cooling/air-conditioning system, or stop the flow
of condensate to the Conlift.

2. Pour the liquid of the collecting tank into a suita­ble container.

3. Pull the inlet hose out of the collecting tank.

Continue the procedure:

6. To ensure that the alarm level is reached,
squeeze the discharge hose (or close the isolat­ing cock, if any), and pour approx. 1.5 litres of
water into the collecting tank.
The pump is started via pressure switch 1.

7. Continue to pour water into the tank until the
alarm pressure switch (pressure switch 2) cuts
out. The buzzer is activated.
Note: The alarm pressure switch must release
the alarm (buzzer) before the water starts to run
out of the Conlift.
For stop/start/alarm levels, see fig. 1, section 3.
Function.

8. Stop pouring water into the tank and stop
squeezing the discharge hose. The alarm
(buzzer) stops. The pump continues to run.
When the stop level is reached, the pump stops.

TM02 7502 3603

10

The release of the alarm (buzzer) ensures that the
the second cut-in of the pump is effected by the
alarm pressure switch (pressure switch 2), see also
section 3. Function.

The Conlift is now ready for operation.
Note: After having checked the function, insert the

inlet hose into the collecting tank and allow the con­densate from the boiler or cooling/air-conditioning
system to flow into the tank.

7. Maintenance and service

Before starting work on the Conlift, the
electricity supply must be switched off. It
must be ensured that the electricity supply
cannot be accidentally switched on.

Condensates from boilers contain acid!
If acid comes into contact with the skin or
the eyes, it may cause irreversible dam­age.

As the Conlift is used for different applications, differ­ent types of contamination may occur, such as lime
incrustations, algae, dust on cooling/air-conditioning
system, or contamination caused by acid in the
boiler.

It is recommended to clean the Conlift regularly to
ensure reliable operation and maximum pump per­formance.

7.1 Cleaning the Conlift

Procedure:

1. Cut off the flow of condensate from the boiler or
cooling/air-conditioning system, or stop the flow
of condensate to the Conlift.

2. Make sure that the hoses are not mechanically
or chemically damaged.

3. Remove the inlet hose. The condensate running
out of the hose must be collected in a suitable
container.

4. Remove the Conlift from wall or floor.

5. Remove the motor cover.

6. Pour the entire contents of the collecting tank
into a suitable container.

7. Remove the screws for the collecting tank cover
(pos. 3), see fig. 8, and lift off the cover. Remove
the screws in the pump housing (pos. 4) and
remove the pump housing.

8. Remove deposits, dirt, algae and incrustations
with a damp cloth.

9. Remove the screws holding the discharge stub
in place, and remove the discharge stub and
non-return valve ball.

10. Also remove deposits, dirt, algae and incrusta­tions from the radial seal (pos. 14) with a damp
cloth.

11. Assemble the Conlift in the reverse order.

12. For start-up, see section 6.

7.2 Contaminated lifting station or compo­nents

Note: If a Conlift lifting station has been used for a

liquid that is injurious to health or toxic, the lifting sta­tion is classified as contaminated.

If Grundfos is requested to service a contaminated
lifting station, Grundfos must be contacted with de­tails about the pumped liquid, etc. before the lifting
station is returned for service. Otherwise Grundfos
can refuse to accept the lifting station for service.

However, any application for service (no matter to
whom it may be made) must include details about
the pumped liquid, if the lifting station has been used
for liquids that are injurious to health or toxic.

Before a lifting station is returned, it must be cleaned
in the best possible way.

Possible costs of returning the lifting station are paid
by the customer.
