Safety Information

6
The pump must only be operated at the frequency specified for the
motor.
7
After having connected the motor and each time after having made
changes to the wiring, check the motor’s direction of rotation.
A wrong direction of rotation can cause a pressure buildup on the
intake side. Moreover, the pump may suffer severe damage.
8
Install a suitable motor protection for the electric motor before starting
up for the first time. Note the information in these Operating
Instructions and on the nameplate.
9
Before starting, check to ensure that the junction box is undamaged,
run a visual inspection on on the seals.
10
Install add-on parts (pressure switches, for example) without any
mechanical tensions and protect these against being damaged by
impacts, for example.
11
Lay the connecting lines so that these cannot be damaged. Protect
the lines against humidity and contact with water. Avoid thermally
stressing the lines by unfavourable laying. Comply with the required
standards when designing and laying the electrical connections.
12
Provide strain relief for the connecting lines so that the plugs and the
line connectors are not subjected to excessively high mechanical
stresses.
13
Lay electric feed lines so that there is no risk of
tripping
over these.
14
The pump must be integrated in the system control arrangement so
that it can not run-up automatically after it has been shut down due to
overtemperature. This applies equally to emergency shut-down
arrange ments. After having determined the fault cause, the pump
should be switched on manually again.
0.3 Thermal Hazards
1
Under certain ambient conditions parts of the the pump may attain
temperatures over 80 °C. There then exists the risk of suffering burns.
Note the danger symbols on the pump and in the case of a hot pump
wear the required protection equipment. All work on a pump which is
“still warm from operation” should be done only whilst wearing protec-
tive gloves.
2
Handle the pump only while vented and after having let it cool down.
3
Before disassembling any cooling water lines, leave the pump to cool
down, shut off the feed line.
4
When uninstalling the cooling water lines, take note of splashing water.
Heated water can cause burns.
5
Never remove the oil-fill or oil-drain plugs while the pump is running.
There exists the risk of suffering burns. Always wear protective gloves
and protective goggles also for protection against the oil.
