Electrical Connection - Pentair Jung Pumpen OXYLIFT 2 Instructions De Service

www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10
For installations in areas subject to explosion hazards, special
regulations apply!
Submersible pumps of the oxylift 2 range are suitable for dos-
ing and pumping wastewater in small-scale clarification plants.
WARNING!
The pump must only be connected to sockets that have been
installed properly in accordance with the regulations and are
protected with at least 10 A (slow) and RCD-safety switches
(30mA).
DANGER!
The pump must never be used when a person is in the water.
Modes of operation
Pumped medium at a temperature of 95°F (35°C): continuous
operation S1.
Pumped medium at a temperature of 140°F (60°C):
intermittent operation S3, 40%,
i.e. 4 min. operation and 6 min. interval.
The submersible pump is frost-resistant down to -4°F (-20°C)
when stored in dry conditions. When installed, however, it
must not be allowed to freeze in the water.
Transport
The pump must always be lifted by the handle and never by the
power supply cable or the float of the level control! The pump
should only be lowered into deeper chambers or pits using a
rope or chain.

ELECTRICAL CONNECTION

NOTICE! Only qualified electricians may carry out electrical
works to the pump or the controls.
The relevant standards (such as EN standards), country-spe-
cific regulations (such as VDE in Germany), and the regulations
of the local power supply companies must be observed.
NOTICE! Never put the free lead end in water! If water gets into
the plug, this can cause malfunctions and damage.
Observe the operating voltage (see the type plate)!
No additional motor protection is required, since the system
has an integrated winding thermostat. Inadmissible tempera-
tures and operating times will result in the thermostat switch-
ing the system off (please refer to the section entitled Appli-
cation). After the thermostat has switched off the system, pull
out the mains plug before remedying the fault, since the device
can switch itself on again automatically after cooling down if
the power is still connected!
APPLICATION
Replacing the connection cable
Only use original manufacturer' s parts. We recommend replac-
ing the seal and the screws each time the connection cable is
replaced.
NOTICE! When the connection cable is loosened, the motor
compartment is opened. Please ensure clean and dry condi-
tions when handling the device.
NOTICE! Do NOT use a power screwdriver. A size 2 PZ screwdri-
ver must be used to unscrew and tighten the connection cable.
Grease the sealing ring with Vaseline before inserting the car-
tridge. Then tighten the screws by hand (max 1 Nm).
INSTALLATION
The pump must be securely fixed to ensure that it does not be-
come detached during operation. The pump should be fixed at
the control head and the discharge branch.
Venting the pump housing
The pump can be vented by providing a 6 mm drill-hole in the
pump housing. This drill-hole allows the pump housing to be
reliably vented even if a non-return valve is used.
NOTICE! If the pump is malfunctioning, a slight leakage of the
contents of the oil reservoir into the pumping medium is pos-
sible.
