Remote Alarm Indication; Installation - Pentair JUNG PUMPEN K2 PLUS Instruction Manual

ENGLISH
The alarm continues to sound as a continuous tone, the display
in the lid will light up red, and the potential-free fault indicator
contact will remain activated.
To turn off the continuous alarm tone, briefly interrupt the
power supply (unplug it from the mains, remove the fuse, ...).

Remote alarm indication

The standard fault indicator contact (change-over contact
0.5A/230V) is designed for connecting an external alarm de-
vice or for the fault indicator input of the heating control sys-
tem). When resting, contacts 40/42 are closed, and if the alarm
sounds in a continuous tone then contacts 40/41 are closed.
For the alarm relay system, a multi-conductor sheathed cable
with a rated voltage of at least 300/500 V must be used, such
as H05... or equivalent; permissible wire size 0.5 - 1.5 mm². To
ensure that the strain relief and seal function properly, the ca-
ble must have a diameter between 5 and 8 mm.
The length of the free conductors (unsheathed length) should
be kept as short as possible (not longer than 15 mm).
Insert the alarm connection cable into the condensate pump
housing parallel to the mains cable. To do so, the second open-
ing in the cable grommet must be opened up.
Feed the cable through the two strain relief clamps to termi-
nals 40-41-42. When connecting the conductors, make sure
that they are securely fixed to the terminals. Then tighten both
clamps.

INSTALLATION

NOTICE! It is not permitted to use the appliance outdoors.
The following points must be observed when choosing a suit-
able location for installing the pump:
• The condensate must flow into the condensate pump from
the siphon trap using gravity.
• The louvres on the K2 plus for ventilating the pump must not
be obstructed.
• The connecting hoses must be laid in such a way that there
are no kinks in the piping.
• The K2 plus must be easy to access to allow maintenance to
be carried out.
Pump
The condensate pump can be either floor-standing or wall-
mounted.
If wall-mounted, the distance between drill-holes must be 19.5
cm. Please use the fastening hardware supplied. It is easy to
level off the pump using the grid pattern on the back of the
pump.
NOTICE! The pump must be installed in an absolutely horizon-
tal position as shown in the example.
Inlet
The K2 plus has three inlets from above (2x ø28 and 1x ø33).
Unused openings must be closed off with plugs. The inlet hose
from the boiler or refrigerator/air conditioning must be laid in
such a way that the condensate can flow into the pump from
the siphon trap using gravity. To avoid obstructions, the inlet
hose must be cut off obliquely. A siphon must be fitted in all
inlets, unless this is already available in the heater, to prevent
exhaust from entering.
The connection of safety modules is not permissible.
Pressure line
NOTICE! Do not use grease or hose clamps to attach the hose
to the discharge branch.
The hose must be laid from the condensate pump to the waste-
water collecting sewer. The DN 50 connection piece supplied
facilitates the connection. The smallest admissible radius
when laying the hose is 60 mm.
It would be advantageous if the hose outlet was located at ap-
proximately the same height as the pump. This would consid-
erably enhance the pumping performance, avoid deposits in
the hose and extend the life of the pump as a result.
Take the pressure line up vertically to the highest possible
point and then route it to the discharge point with a slight
downward gradient.
NOTICE! The pressure line, from its highest point, must be
able to completely discharge its contents. Pockets of air in the
pressure line increase the pumping resistance.
Alternatively to using the hose supplied (ø10 mm), it is also pos-
sible to use your own 12 mm hose for this purpose. This will
reduce the resistance and increase the pump performance if
necessary.
NOTICE! If the condensate pump is installed below the back-
flow level and the discharge point is located on a sewer which
is below the back-flow level and is not protected against back-
flow, then the pressure line must be laid with a loop located
above the back-flow level. The connection to the sewer must
be pressure-tight.
