Electrical Connection - Pentair Jung Pumpen OXYPERL 3 Instructions De Service

ENGLISH
APPLICATION
The OXYPERL range of submersible moto-
rised aerators is suitable for aerating and
circulating wastewater in small-scale clari-
fication plants. Other uses, for instance, are
the insertion of oxygen into garden ponds or
fish ponds.
When using the aerators, the relevant na-
tional laws, regulations and stipulations
must be adhered to, for example:
• Household and similar electrical appli-
ances - Safety (e.g. DIN EN 60335-2-41 in
Germany )
• Installation of low voltage systems (e.g.,
VDE 0100 (30 mA FI) in Germany)
Aeration of wastewater
The aeration propeller develops a vacuum
and takes air in through the suction hose,
which is connected to the atmosphere. The
narrow air ducts in the aeration propeller ac-
celerate the air and release it into the waste-
water in fine bubbles.
The aerator is optimised for a particular sub-
mersion depth. At greater depths the air in-
sertion performance decreases. To maintain
the best possible air insertion performance it
is important to adhere to the specified depth
(please refer to the section entitled Installa-
tion).
Circulation of wastewater
The OXYPERL circulates the wastewater in
the small-scale clarification plant and, as a
result of this, the activated sludge flakes are
evenly distributed in the wastewater.
Due to a special wing design, the flake struc-
ture of the activated sludge is preserved well.
This is an important condition for achieving
good clarification results.
Temperatures
The maximum temperature of the wastewa-
ter medium is 86°F (30°C).
The submersible motorised aerator 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
ATTENTION! The aerator must always be
lifted by the handle and never by the power
supply cable! The aerator should only be low-
ered into the medium using a rope or chain.
ATTENTION! During transport and when
setting the aerator down, there must not be
any mechanical load exerted on the aeration
propeller.

ELECTRICAL
CONNECTION
Only qualified electricians may
carry out electrical works to the
pump or the controls.
The relevant standards (such as EN stand-
ards), country-specific regulations (such as
VDE in Germany), and the regulations of the
local power supply companies must be ob-
served.
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 mo-
tor protection is required, since the system
has an integrated winding thermostat. Inad-
missible temperatures and operating times
will result in the thermostat switching the
system off (please refer to the section enti-
tled Application). After the thermostat has
switched off the system, pull out the mains
plug before remedying the fault, since the
aerator can switch itself on again automati-
cally 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 aerator.
ATTENTION! Do NOT use a power screw-
driver. A size 2 PZ screwdriver must be used
to unscrew and tighten the connection cable.
Grease the sealing ring with Vaseline before
inserting the cartridge. Then tighten the
screws by hand (max 1 Nm).
INSTALLATION
The OXYPERL 3 develops a thrust of 20 N,
and the OXYPERL 5 a thrust of 38 N, due to
the propeller. The aerator must therefore be
securely attached to prevent it from twisting
or slipping.
During installation, particular care must be
taken to ensure that the four cooling surfaces
under the control head are fully submersed
in the wastewater and that the prescribed in-
stallation dimensions of at least 200 mm are
complied with! If there is insufficient cooling,
the motor temperature will rise and the elec-
tric motor will switch off automatically.
