Grundfos Conlift1 Installation Und Betriebsanleitung Seite 10

6.4 Operating mode
The Conlift is designed for max.
Caution
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
Note
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.
Check that the installation has a 10 A slow-blowing
fuse on the mains side and an earth leakage circuit
breaker according to IEC 345.
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.
