5.3 Operating mode

The Conlift is designed for maximum 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.

5.4 Handling of condensates

If Conlift is to be connected to a
pressure-reducing valve, observe the
boiler manufacturer's instructions.
When cleaning heat exchangers and
burner units of boiler systems, make sure
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 that you use a neutralisation unit. The
neutralisation unit is included in Conlift2 pH+ and is
available as an accessory for Conlift1 and Conlift2.
See section 9. Technical
The local outlet regulations regarding condensates
from boilers must be met.

6. Control functions

The condensate runs by natural fall through a hose
into the tank. See section
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 the stop level. The
condensate is pumped through the outlet 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 restarts
automatically.
