ENGLISH
x Before each use check the pump,
especially the power cable and plug
for possible damage. Risk of fatal
electric shock!
x A damaged pump must be work-
manlike repaired before it can be
used again.
x Do not attempt to repair the pump
yourself! Only trained specialists are
permitted to service or repair pumps
or pressure vessels.
The pump is easily assembled and con-
nected.
If in doubt, contact your specialist sup-
plier or a qualified electrician.
5.1 Installation
The pump must be placed on a
plane and level surface, suitable of
bearing the weight of the pump fully
filled with water.
To avoid vibrations the pump should
be placed on an elastic base.
The installation location should be
well vented and protected from
atmospheric exposure.
When operated at garden ponds
and pools the pump must be set up
safe against flooding and safe-
garded against falling into the water.
Any additional legal requirements
are to be observed.
5.2 Connecting the Suction
Line
3
Note:
Possibly further accessories may
be required for connection (see "Availa-
ble Accessories").
A
Caution!
The suction line needs to be
installed in such manner that it does
not exert mechanical force or distor-
tion to the pump.
A
Caution!
When pumping contaminated
fluids install a suction strainer to pro-
tect the pump from sand and dirt.
3
Note:
A check valve is recommended to
prevent water backflow when the pump
is turned off.
All screw fittings must be sealed
with thread sealing tape; leaks
cause the priming of air, which
reduces or completely prevents the
priming of water.
The suction line should have an
inner diameter of 1" (25 mm) mini-
mum and must be kink and vacuum
resistent.
Keep suction line as short as practi-
cal, as with increasing length the
pump capacity is reduced.
The suction line should ascend
towards the pump to prevent air
locks.
A sufficient water supply must be
ensured, the foot valve at the end of
the suction line must be submerged
in water at all times.
5.3 Discharge Port
3
Note:
Possibly further accessories may
be required for connection (see "Availa-
ble Accessories").
A
Caution!
The discharge (or pressure)
line needs to be installed in such
manner that it does not exert mechan-
ical force or distortion to the pump.
All screw fittings should be sealed
with thread sealing tape to prevent
leakage.
All parts of the pressure line must be
resistant to internal pressure.
All parts of the pressure line must be
installed in a workmanlike manner.
A
Danger!
Improper installation and use
of parts not resistant to internal pres-
sure can cause the pressure line to
break during operation. Risk of per-
sonal injury by liquid spurting from
the line under high pressure!
5.4 Connection to a Pipe
System
A stationary installation (e.g. in an indoor
domestic water system) is also possible.
To reduce vibrations and noises the
pump should be connected to the
pipe system with flexible tubing.
5.5 Connection to AC Power
B
Danger! Risk of electric shock!
Do not operate the pump in wet
environment and only under the fol-
lowing conditions:
Connect only to an earthed outlet
that is properly installed, earthed
and tested.
Mains voltage and fuse protection
must correspond with the
requirement stated in the "Tech-
nical Specications".
When operated at pools, garden
ponds and similar locations, the
pump must be protected by a
residual current operated device
(RCD, 30 mA) (DIN VDE 0100 -702,
-738 or equivalent applicable
local regulations).
We recommend the use of RCD's
as a general precaution for per-
sonal protection.
When operating the pump out-
doors the electrical connections
must be splash-proof; the con-
nections must not be placed into
water.
Use only extension cables of suf-
ficient lead cross section (see
"Technical Specifications"). Com-
pletely unroll cable reels.
5.6 Filling the pump and
priming
A
Caution!
After installation, loss of water
or priming of air the pump needs to
be filled with water. Starting the pump
without water causes damage!
3
Note:
The suction line does not need to
be filled, the pump is self-priming. How-
ever, depending on length and diameter
of the suction line it may take some time
until pressure has built up.
1. Remove the water filler plug, com-
plete with gasket.
2. Slowly pour in clear water, until the
pump is filled.
3. To reduce the time needed for prim-
ing you can also fill the suction line.
4. Replace the water filler plug, com-
plete with gasket.
5. Open pressure line (open tap or
spray nozzle) for any air to escape
during priming.
6. Start pump (see "Operation").
7. Turn pump OFF when water runs
out steadily.
Pump and suction line must be con-
nected and filled (see "Prior to Opera-
tion").
A
Caution!
The pump must not run dry.
Ensure there is always sufficient
pumping medium (water) available.
x If the motor does not start, no pres-
sure is built up or similar effects are
evident, switch the pump OFF – and
try to resolve the fault (see "Trouble
Shooting").

which pump capacity is possible in
dependance on the delivery head.

  • Ich möchte das Luftventil unserer Elektra Beckum HWA 4000 N wechseln .Das neu gelieferte Ventil ist anders
    es wird mit einer Mutter am Kessel befestigt. Das ist bei dem defekten Ventil so nicht, deshalb weiß ich nicht
    weiter. Möchte aber keine Gewalt anwenden, z. B. durch ausbohren des Venils.
