Maintenance And Cleaning - AL-KO HWA 1304 F Bedienungsanleitung

During the first operation the pump auto-
matically switches off after approx. 10 sec.
Afterwards the button "RESET"(28) must
be pressed so long until the pump delivers
water. If the button "RESET" is released
before the pump delivers water, the pump
switches off automatically due to safety
reasons. Should the suction process last
longer than 2 min. refill the pump and
suction hose once again, check screw
connections for tightness and repeat the
process.
•
As soon as the flow of water is cleared of air
bubbles trapped in the line, close the pres-
sure line. When the pressure has fallen and
the reservoir is full, the pump will automati-
cally in approx. 15 sec. switch off. Your do-
mestic water system is now ready for opera-
tion.

Maintenance and Cleaning

Before beginning any maintenance or
cleaning work, make sure that the device
has been unplugged and take precautions
to ensure that it cannot be switched on
during work!
Cleaning the system
If you have used your domestic water system to
pump chlorine water (swimming pool water) or
liquids which leave a residue, flush your pump
out with clear water after use.
Cleaning the filter (only HWA 1300 F)
•
Remove the screw plug (7) from the drain-
age opening, empty the filter chamber and
close the drainage opening again
•
Unscrew the filter cover (9) with the help of
the filter spanner.
•
Remove the filter (20) from the pump head
and clean it under flowing water.
•
Prior to installing the filter, check the two
seals (19) on the filter and the seal (23) for
damage, if necessary renew.
The seal (23) must be correctly inserted in
the seal seat on the pump head (see Detail
in Fig. D). If necessary lightly grease the
seal with non-acidic fat.
•
Install the filter, screw on filter cover and
tighten firmly with the hand using filter span-
ner.
Clearing blockages (HWA 1001 INOX)
Eliminate blocking inside the pump as follows:
•
Remove the suction hose on the pump inlet
(8).
•
Attach the pressure hose to the water tap
and spray water into the pump chamber until
the blockage is flushed out.
•
Check to see that the obstruction has been
cleared entirely by switching on the pump for
a short time.
