HWA 1001 INOX HWA 1300 F - AL-KO Garten + Hobby

When attaching the suction and pressure
hoses, make sure that they do not exert a
tension on the device. We recommend the
use of flexible hoses at the pump inlet (8)
and outlet (11). If you have any questions,
ask your retailer.
When operating the system (automatic
operation), take appropriate measures to
ensure that damage due to flooding cannot
occur if the system should malfunction.
This can be ensured, for instance, by
installing an alarm system or a reserve
pump.
Attaching the suction hose
Choose a hose which is long enough so
that the device will not suck in air and run
dry. The hose should be at least 30cm
under the surface of the liquid to be
pumped while the pump is in operation.
Mount a non-return valve in the suction
hose to prevent the liquid from running
back out of the pump.
• Attach the suction hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
If the liquid to be pumped is deeper than
4 m, you should use a suction hose which
is larger than 1“in diameter for the best
performance. We recommend our AL-KO
suction set (18), which consists of a
suction hose, strainer and non-return
valve. The suction set is available at your
local retailer’s.
Before pumping sandy water, you must
insert a pre-filter (17) (only HWA 1001
Inox) between the suction hose and the
pump inlet or you will dam- age your
domestic water system.
The filter is available at your local retailer’s.
• When laying the suction hose, make sure
that it is lower than the system.
If the suction hose is laid so that it is higher
than the device, bubbles will become
trapped in the line and the pump will suck
air.
Mounting the pressure switch (hydrocontrol)
Screw the connection nipple (13) with seal ring
for pump outlet (12) on the pump outlet. Pay
attention to have a tight connection without
damaging the threads. Screw the pressure
switch (1) with flat seal ring (14) with the connection
nipple (13).
The arrow printed on the pressure switch
(1) must point in the direction of flow.
The system does not function properly if:
− The pumping point 15 m lies higher
than the water system.
− The arrow printed on the pressure
switch (1) does not point in the flow direction.
− The pressure switch is not mounted in
upright position.
Attaching the pressure hose
• Attach the pressure hose. Make sure to
screw it in tightly, but take care not to damage
the threads.
Filling the pump and suction hose
Before putting your domestic water system
into operation, you must fill the pump
chamber with water until it overflows to
achieve full suction power. Do not operate
the pump while it is dry because this will
cause serious damage to the pump.
• Remove the filler screw (10).
• Pour water into the opening until the chamber
of the pump (5) is full.
• Replace the filler screw (10) and tighten it.
The pump cannot be filled via hydrocontrol,
since a non-return valve is installed
towards the pump.
Switching on the system
• Open one of the fittings in the pressure line
(valve, sprayer, tap, etc.).
• Plug the electric cable into the socket. The
pump will begin to run.
