NOTE
When pumping out a tank, ensure that the fluid level is always high
enough above the suction port of the pump so that the pump never
runs dry. The minimum intake pressure must be maintained.
• When the pump is used in air-conditioning or cooling systems, the
condensation that forms in the lantern can be drained specifically via
an existing hole. A drain pipe can be connected at this opening. Small
amounts of fluid leakage can be also drained off.
NOTE
In the case of insulated systems, only the pump housing may be insu-
lated, not the lantern or motor.
The motors are equipped with holes for condensation which are
sealed with plastic plugs at the factory (in order to guarantee that
protection class IP 55 is achieved).
• If used in air-conditioning/cooling systems, this plug must be
removed downwards so that condensation water can drain.
• With a horizontal motor shaft, the condensate hole must be posi-
tioned towards the bottom. If necessary, the motor must be turned
accordingly.
NOTE
If the plastic plug is removed, protection class IP 55 is no longer
ensured!
DANGER! Risk of fatal injury!
A fatal shock may occur if the electrical connection is not made
correctly.
• Only allow the electrical connection to be made by an electrician
approved by the local electricity supplier and in accordance with
the local regulations in force.
• Observe the installation and operating instructions for the acces-
sories!
DANGER! Risk of fatal injury!
Contact voltage hazardous to human life
Work on the module may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage (capacitors).
• Before working on the pump, disconnect the power supply and
wait for 5 minutes.
• Check to ensure all connections (including potential-free contacts)
are voltage-free.
• Never use an object to poke around the openings on the module
and never insert anything into the module!
WARNING! Risk of mains overload!
An inadequate mains design can lead to system failures and even to
cable fires due to mains overload.
• When designing the mains, with regard to the cable cross-sections
and fuses, give special consideration to the fact that short-term
simultaneous operation of all pumps is possible in multi-pump
operation.
