Setting The Pressure Switch - AL-KO HW F 1000 Mode D'emploi

•
Prior to installing the filter, check the two
seals (21) on the filter and the seal (16) for
damage, if necessary renew.
The seal (25) must be correctly inserted in
the seal seat on the pump head (see Detail
in Fig. C). 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.
Removing and mounting of non-return
valve, cleaning

it under flowing water.
•
Renew seal (24) if necessary.

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.
•
Empty the suction and pressure hoses.
•
Remove the draining screws (9) and (12)
drain all water from the pump chamber. The
water contained in the reservoir will be
pressed out by the air bellows.
•
Replace the draining screws and store the
device so that it is protected from frost.

Setting the pressure switch

The cut-in and cut-out pressures at which the
sys- tem starts and stops operating have been
set in the factory (see technical data). However,
if desired, you can adjust the setting as desired
at the pressure switch (10).
Settings on the pushbutton switch and on
the electrical part of the house water plant
may be performed only by the responsible
customer service.
Checking the inlet pressure
•
Unplug the electric cable from the socket.
•
Open the pressure line and drain the water
off until the pump is completely empty.
•
Check the inlet pressure at the diaphragm
(5).
•
The pressure should be approx. 1.5 bar.
Correct the pressure if needed.
•
Put the domestic water system into operation
as set out in the instructions.
