The pump must only be connected
to sockets that have been installed
properly in accordance with the re-
gulations and and are protected
with at least 10 A (slow) and FI-
safety switches (30mA).
Check the plug and the mains cable
for signs of mechanical and chemi-
cal damage. A damaged or kinked
hose must be replaced.
Condensate from condensing boil-
ers contains acids! These can cause
irreparable damage if they come
into contact with skin or eyes.
APPLICATION
The condensate pump K2 was specially
developed for removing aggressive con-
densate from condensing boilers (up
to 100 kW), refrigerated and freezer
display cases, air conditioning systems
and air dehumidifiers.
Condensate from condensing
boilers contains aggressive ac-
ids.
You will find further information in the
DWA working paper "Condensates from
condensing boilers", (ATV-DVWL-A 251).
If installed in compliance with the regu-
lations and used properly, then this ap-
pliance meets the protective require-
ments of the EMC directive 2004/108
EC and is suitable for domestic use and
connection to a power supply from the
grid.
To avoid deposits, the volume flow in the
pressure pipe should be at least 66 li-
tres/hour, based on the use of the pipe
supplied (please refer to the section en-
titled "Installation - Pressure pipe" for
more information).
ATTENTION! It is not permitted to in-
stall the unit outdoors.
When installing in bath and
shower rooms, the applicable
electrical regulations must be
observed (in Germany VDE 0100 part
701)!
Pumped media
ATTENTION! The pump is only suitable
for pumping electrically conductive liq-
uids.
Due to the configuration of the elec-
trode circuit, it is essential that a test
run be carried out with the condensate
in question after the condensate pump
has been installed!
ATTENTION! The maximum admissi-
ble temperature of the pumped media
is 104°F (40°C). In the event of higher
intake temperatures, even for a short
time, the inlet pipe must be laid in the
form of several cooling loops.
Provided that regular maintenance is
performed, the pump unit can convey
condensate with a pH value of ≥ 2.7. If
lower pH values are present, even if only
intermittently, then a neutralisation sys-
tem must be fitted upstream.
In addition, local conditions or par-
ticular technical or legal requirements
(such as local drainage bye-laws) may
require the use of a neutralisation sys-
tem.
ATTENTION! Admixtures of oils, par-
ticularly essential oils are not permit-
ted.
Storage
The K2 is frost-resistant down to -4°F
(-20°C) when stored in dry conditions.
When installed, however, the conden-
sate in the pump unit must not be al-
lowed to freeze.
ELECTRICAL
CONNECTION
Only qualified electricians may
carry out electrical works to
the pump or the controls.
Before carrying out any work,
pull out the mains plug and en-
sure that the power supply to
the unit cannot be switched on again by
anyone else.
ATTENTION! Never put the mains plug
in water! If water gets into the plug, this
can cause malfunctions and damage.
The relevant standards (such as EN
standards),
country-specific
tions (such as VDE in Germany), and the
regulations of the local power supply
companies must be observed.
Observe the operating voltage (see the
type plate)!
Only connect the pump to safety sock-
ets that have been installed properly
in accordance with the regulations. No
additional motor protection is required,
since the system has an integrated
winding thermostat.
Unacceptably high temperatures cause
the thermostat to shut down the motor.
After
switched off the system, pull
out the mains plug before rem-
edying the fault, since the appliance can
switch itself on again automatically if
the power is still connected!
Level control
The K2 condensate pump has a level
control that switches the pump on and
off depending on the level of the wa-
ter. An integrated alarm system beeps
if there is a malfunction, even if this is
only temporary. The K2 has a potential-
free fault indicator contact on the circuit
board (0.5A/230 V) for remote alarm in-
dication.
Alarm
The alarm is for early reporting of faults
(such as kinked piping, inadequate
pump performance) before more seri-
ous failure can occur.
If the condensate pump runs but does
not reach the switch-off point within ap-
prox. 60 seconds, then the alarm will
sound.A loud alarm tone sounds but the
pump carries on running.
If the K2 reaches the switch-off point
within the 60 seconds that follow, the
pump will shut down and the alarm will
stop.
If the K2 does not reach the switch-off
level within that time, then the conden-
sate pump will shut down for safety rea-
sons to prevent damage from occurring
as a result.
The alarm continues to sound as a con-
tinuous tone and the potential-free fault
indicator contact will activate (e.g. fault
indicator input of the heating control
system, alarm device...).
To turn off the continuous tone, briefly
interrupt the power supply (unplug from
the mains, remove the fuse, ...).
regula-
To avoid damaging the appliance, the
overflow
connection
drainage and the signal contact must
be used.
Remote alarm indication
The standard fault indicator contact
(change-over contact) is designed for
connecting an external alarm device.
When resting, contacts 40/42 are closed,
and if the alarm sounds in a continuous
tone then contacts 40/41 are closed.
