4.4 Low-level pumping at low water level
In case of low water level (< 10-15 cm) there is not enough water inside the spiral hous-
ing to do low-level pumping. For this first the pump has to be filled. Therefor the following
points are to be observed:
1. Bring the pump into low-level pumping
position (see section 4.3).
2. Mount a 90° elbow with B-Storz cou-
plings on both sides to the outlet side of
the pump.
3. Fill the pump with water until water
drains off the inlet openings of the pump.
Now the pump is sufficiently filled with
water in order to start low-level pumping.
4. Mount a suitable pressure hose to the 90°elbow on the suction side of the pump and
start the start pump as described in section 4.1 and 4.3 of this manual. It takes about
10-15 seconds until the pumps achieves its normal capacity.
4.5 Use of the pump with pluggable float switch
To operate the pump with pluggable float switch (optional accessory), first insert the plug-
gable switch into a socket which is protected by a residual current device (RCD) with rated
residual current of not more than 30 mA and then connect the motor protection plug to the
pluggable float switch. When operating the pump with float switch, also note the points
listed under section "4.1 Use of the Pump". The follow-
ing is also to be observed:
1. Mount the float switch on the cable lug in such a
way that it cannot be sucked by the pump.
2. The float switch must only hang in the medium to
the extent that it switches off shortly before the
pump sucks air at the latest.
4.6 Operation with emergency power generator
All Tegernsee pumps can be operated with 3 kVA DIN power generators. In the case of
3 kVA units wherever possible the pump should be connected to the unit directly (i.e. with-
out an extension cable), as otherwise there is a risk of the unit stalling on switching on the
pump.
With generators with higher power, extension cables can be used without restriction. The
used extension cable must have a wire cross-section of at least 2.5 mm² or larger to keep
the voltage drop in the cable as low as possible.
