6.5 Handling of condensates

If Conlift is to be connected to a
Note
pressure-reducing, observe the boiler
manufacturer's instructions.
When cleaning heat exchangers and
burner units of boiler systems, make sure
Note
that no acid and cleaning residuals enter
the condensing unit.
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

Conlift must be installed according to local
Note
regulations.
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
condensate source or external
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
