Electrical Connection; Level Control - Pentair JUNG PUMPEN K2 PLUS Instruction Manual

Never work alone. Always wear a hard hat, safety glasses and
safety shoes and, if necessary, a suitable safety belt.
Before carrying out welding works or using electrical devices,
check to ensure there is no danger of explosion.
People working in wastewater systems must be vaccinated
against the pathogens that may be found there. For the sake
of your health, be sure to pay meticulous Notice to cleanliness
wherever you are working.
Make sure that there are no toxic gases in the working area.
Observe the health and safety at work regulations and make
sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium may be hot
and could cause burns.
For installations in areas subject to explosion hazards, special
regulations apply!
The K2 plus condensate pump was specially developed for re-
moving aggressive condensate from condensing boilers (up to
100 kW), refrigerated and freezer display cases, air condition-
ing systems and air dehumidifiers.
NOTICE! The maximum admissible temperature of the pumped
media is 40°C. In the event of higher media inlet temperatures,
even for a short time, the inlet hose 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 neutrali-
sation system must be fitted upstream.
In addition, local conditions or particular technical or legal re-
quirements (such as local drainage bye-laws) may require the
use of a neutralisation system.
NOTICE! Admixtures of oils, particularly essential oils, are not
permitted.
The use of the K2 plus is not permissible for removing waste
water, such as from washbasins.
CAUTION!
Condensates from condensing boilers contain acids! These
can cause irreparable damage if they come into contact with
skin or eyes.
NOTICE! The maximum influx is 14 l/h. The temporary peak in-
flux, such as when defrosting must not exceed 70 l/h.
NOTICE! The maximum delivery head of 3.5 metres must not
be exceeded in order to prevent deposits from forming and
keep the pump in good working order.
It is not permitted to use the K2 plus outdoors. When installed
in bath and shower rooms, the applicable electrical regulations
must be observed (in Germany VDE 0100 part 701)! You will find
further information in the DWA working paper "Condensates
from condensing boilers" (ATV-DVWL-A 251).
In the countries of destination, the standards, regulations,
rules and directives that apply in that country must be imple-
mented.

USE
Storage
The K2 plus is frost-free if stored in a dry place at up to -20°C.
The condensate in the system must not freeze however in its
built-in state.

ELECTRICAL CONNECTION

Current applicable standards (such as EN standards), national
regulations (such as VDE in Germany), and the regulations of
the local power supply companies must be complied with.
NOTICE! Only qualified electricians may carry out electrical
work on the pump, plug or the control unit.
NOTICE! Never put the mains plug in water! If water gets into
the plug, this can cause malfunctions and damage.
Observe the operating voltage (see type plate)!
WARNING!
Only connect the pump to electrical circuits that have been
installed properly in accordance with the regulations and are
fitted with at least a 10 A (delay) fuse and an FI circuit breaker
(≤30 mA).
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.
WARNING!
After the thermostat has switched the system off, unplug the
mains cable before remedying the fault, since the pump unit
can switch itself on again automatically if the power is still con-
nected!

Level control

The pump is switched on and off automatically depending on
the level of water in the collecting tank. A multi-coloured dis-
play in the lid indicates the current operating status of the unit:
• Green - Standby
• Green flashing - Pump in operation
• Green/orange - Alarm, pump is running
• Red - Alarm, pump switched off
Alarm
The first alert level is for early reporting of faults
①
(such as kinked piping, inadequate pump performance) before
more serious failure can occur.
If the condensate pump runs but does not reach the switch-
off point within approximately 60 seconds, then the alarm will
sound. A loud alarm tone sounds, the display on the top flashes
green/orange, the potential-free contact is switched, but the
pumps carries on running.
If the K2 plus reaches the switch-off point within the 60 sec-
onds that follow, it will revert to "standby" mode and the alarm
will stop.
If the switch-off level is not reached within a total
②
of 120 seconds, then the condensate pump will shut down for
safety reasons to prevent damage from occurring as a result.
