In environments where there is risk of explosion, motors classified as explosion safe must
be used, along with special safety devices. Check with the governmental agency
responsible for such precautions.
Improper installation can cause fatal injuries.
Dust, liquids and gases that can cause overheating, short circuits, corrosion
damage and fire must be kept away from motors and other exposed
equipment. If the pump handles liquids hazardous for person or
environment, some sort of container must be installed into which leakage
can be led.
If the surface temperature of the system or parts of the system exceeds
60°C, these areas must be marked with warning text reading "Hot surface" to
avoid burns.
The pump unit must not be exposed to rapid temperature changes of the liquid without
prior pre-heating/pre-cooling. Absolutely forbidden to flush a hot pump with cold water.
Big temperature changes can cause crack formation or explosion, which in turn can entail
severe personal injuries.
The pump must not operate above stated performance.
Before intervening in the pump/system, the power must be shut off and the
starting device be locked. When intervening in the pump unit, follow the
instructions for disassembly/assembly. If the instructions are not followed,
the pump or parts of the pump can be damaged. It will also invalidate the
warranty.
If the pump does not function satisfactorily, contact your distributor.
