Maintenance And Care - AL-KO HW F 1004 Betriebsanleitung

Startup
Attaching the pressure hose
1. Screw the connection nipple (17) with the
round seal ring (18) in the pump outlet (3).
2. Screw the angular nipple (15) with the flat seal
(16) on the connection nipple (17) and rotate
the angular nipple in the desired direction.
3. Attach the pressure hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
Filling the pump
CAUTION!
Before putting your domestic water sys-
tem into operation, you must fill the pump
chamber with water until it overflows to
achieve full suction power. Do not ope-
rate the pump while it is dry because this
will cause serious damage to the pump.
1. Remove the filler screw (2).
2. Pour water into the opening until the chamber
of the pump (1) is full.
3. Replace the filler screw (2) and tighten it.
Switching on the system
1. Open the pressure line (open valve, sprayer,
tap, etc.).
2. Plug the electric cable into the socket. The
pump will automatically begin to run.
3. 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 switch off. Your domestic water system
is now ready for operation.
Switching off the Pump
1. To switch off the pump, just pull the plug of
the electric cable from the socket.

MAINTENANCE AND CARE

CAUTION!
Before beginning any maintenance or
cleaning work, make sure that the pump
has been unplugged and take precauti-
ons 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 li-
quids which leave a residue, flush your pump out
with clear water after use.

Cleaning the filter
CAUTION!
The seal (25) must be correctly inser-
ted in the seal seat on the pump head
(see Detail in Fig. C). If necessary lightly
grease the seal with non-acidic fat.
1. Remove the screw plug (12) from the drai-
nage opening, empty the filter chamber and
close the drainage opening again.
2. Unscrew the filter cover (14) with the help of
the filter spanner.
3. Remove the filter (22) from the pump head
and clean it under flowing water.
4. Prior to installing the filter, check the two seals
(21) on the filter and the seal (16) for damage,
if necessary renew.
5. Install the filter, screw on filter cover and tigh-
ten firmly with the hand using filter spanner.
Removing and mounting of non-return valve,
cleaning
1. Remove the filter (see Section "cleaning the
filter").
2. Unscrew the non-return valve (23) and clean
it under flowing water.
3. Renew seal (24) if necessary.
4. Install the non-return valve.
5. Install the filter and filter cover.
Frost protection
Your domestic water system is susceptible to low
temperatures. Make sure to empty the device of
residual liquid (hoses, pump and reservoir) and
store it so that it is protected from frost.
1. Empty the suction and pressure hoses.
2. Remove the draining screws (9) and (12)
drain all water from the pump chamber. The
water contained in the reservoir will be pres-
sed out by the air bellows.
3. Replace the draining screws and store the de-
vice so that it is protected from frost.
Setting the pressure switch
CAUTION!
Settings on the pushbutton switch and
on the electrical part of the house water
plant may be performed only by the res-
ponsible customer service.
The cut-in and cut-out pressures at which the sys-
tem starts and stops operating have been set in
