8. Starting up
앬
Set up the house waterworks on a firm, level and
horizontal surface.
앬
Place the pump on a flat, firm surface. Secure
the equipment with screw fasteners suitable for
the surface in question.
앬
Fill the pump case with water through the
delivery line connection. Priming is accelerated if
the suction line is full.
앬
Tightly connect the suction and delivery lines.
앬
Close the delivery line.
앬
Connect up the pump - priming at max. suction
head can take up to 5 minutes.
앬
The pump switches off when the switch-off
pressure (3 bar) is reached.
앬
The pump switches on automatically when water
is consumed and the pressure drops (switch-on
pressure approx. 1.5 bar).
9. Maintenance instructions
앬
The house waterworks requires by and large no
maintenance. Nevertheless we recommend
inspecting and cleaning the appliance in regular
intervals to ensure that it serves you well for
many years.
Caution!
Always disconnect the house waterworks
from the power supply before carrying out
any maintenance. To do so, pull the pump’s
power plug out of the socket-outlet.
앬
If you are not going to use the house waterworks
for a long time or wish to put it into winter
storage, rinse out the pump thoroughly with
water, empty it completely and store it in dry
conditions.
앬
Be sure to empty the house waterworks
completely if there is any risk of freezing
temperatures.
앬
After a lengthy stoppage, switch the appliance on
and off briefly to check whether the rotor turns.
앬
If the house waterworks becomes clogged,
connect the delivery line to the water pipe and
disconnect the suction hose. Now open the water
pipe and switch on the pump for several times for
approx. two seconds. In most cases this will
remove the blockage.
앬
Inside the pressure tank is an expandable water
sack and an air compartment whose maximum
pressure should lie at approx. 1.3 bar. Pumping
water into the water sack causes the sack to
expand so that the pressure in the air
compartment rises to switch-off level. If the air
pressure is too low, you should raise it. To do so,
unscrew the plastic lid from the tank and top up
the pressure to the correct level using a tyre
pump with meter at the valve.
10. Replacing the power cable
Caution! Disconnect the appliance from the
power supply!
If the power cable is defective, have it replaced
by a qualified electrician.
