Electrical Connection - Pentair JUNG PUMPEN OXYLIFT 2 Instructions De Service

APPLICATION
Submersible pumps of the oxylift 2
range are suitable for dosing and pump-
ing wastewater in small-scale clarifica-
tion plants.
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-resist-
ant 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
Attention! 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
Only qualified electricians may
carry out electrical works to
the pump or the controls.
The relevant standards (such as EN
standards), country-specific
tions (such as VDE in Germany), and the
regulations of the local power supply
companies must be observed.
Attention! 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)!
The pump must only be connected up
to electrical installations with an earth
wire in accordance with the regulations.
It must be protected with a 10 A fuse. No
additional motor protection is required,
since the system has an integrated
winding thermostat. Inadmissible tem-
peratures and operating times will re-
sult in the thermostat switching the
system off (please refer to the section
entitled Application). After the thermo-
stat has switched off the system, pull
out the mains plug before remedying
the fault, since the device can switch it-
self on again automatically after cooling
down if the power is still connected!
Replacing the connection cable
Only use original manufacturer's parts.
We recommend replacing the seal and
the screws each time the connection
cable is replaced.
Attention! When the connection cable
is loosened, the motor compartment
is opened. Please ensure clean and dry
conditions when handling the device.
Attention! Do NOT use a power screw-
driver. A size 2 PZ screwdriver must be
used to unscrew and tighten the con-
nection cable.
Grease the sealing ring with Vaseline
before inserting the cartridge.
Then tighten the screws by hand (max
regula-
1 Nm).
INSTALLATION
The pump must be securely fixed to en-
sure that it does not become detached
during operation. The pump should be
fixed at the control head and the dis-
charge branch.
ENGLISH
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 hous-
ing to be reliably vented even if a non-
return valve is used.
Attention! If the pump is malfunction-
ing, a slight leakage of the contents of
the oil reservoir into the pumping me-
dium is possible.
MAINTENANCE
To ensure continued reliability of ser-
vice, we recommend that you take out a
service contract.
Before carrying out any works:
disconnect the pump and the
controls from the mains and
take steps to ensure that no one else can
reconnect them to the power supply.
Check the mains cable for me-
chanical or chemical damage.
A damaged or kinked cable
must be replaced.
When using a chain to lift the
pump, please observe the rel-
evant national regulations re-
garding accident prevention.
The foot strainer prevents coarse impu-
rities from entering the pump. Regular
cleaning of the float and the foot strain-
er to remove fibres and accumulations
ensures optimum performance and op-
eration. To clean the impeller, the foot
strainer must first be levered off. The
impeller can now be cleaned through
the suction opening.
