1. Delivery
The Grundfos Conlift is delivered in a cardboard box
containing:
• Conlift lifting station with built-in non-return valve
and supply cable with Schuko plug or a free cable
end

10/14 mm (pos. 51)
• 2 angular mounting brackets to counteract buoy-
ancy (pos. 52)
• 4 wood screws (pos. 53) and 4 rawlplugs
®
(pos. 54)

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 conden-
sate 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.
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.
In case of deviations from the application conditions
stated above, local electricity regulations and stand-
ards must be observed.
In case of doubt, contact a qualified electrician.
Prior to installation, read these installation
and operating instructions. Installation and
operation must comply with local regula-
tions and accepted codes of good prac-
tice.
Condensates from boilers are aggressive.
They contain acid.
The Conlift must not be used for the trans-
fer of inflammable liquids.
The Conlift must not be installed in poten-
tially explosive environments.
