Figure 6
Completely roll off the high-pressure
hose from the hose drum.
Rotate the hose drum until the screwed-
on semibowl is pointing toward the top.
Loosen all three screws and remove the
loosened semibowl.
Figure 7
Unlatch the fastening clamp for the high-
pressure hose and pull the hose out.
Route the new high-pressure hose
through the intended hose guide and
the deflection pulley at the bottom of the
appliance.
Slide the hose nipple all the way into the
knot section of the hose drum and se-
cure with the fastening clamp.
Replace the half bowl.
For connection values refer to technical
specifications
Connect the supply hose (minimum
length 7.5 m, minimum diameter 3/4“) to
the water connection point of the ma-
chine and at the water supply point (for
e.g. a tap).
Note:
The supply hose is not included.
If you want to suck in water from an exter-
nal vessel, the following modification is
necessary:
Figure 8
Remove the system care bottle.
Release and remove the cover of the
system care.
Remove water connection from the fine
filter.
Unscrew the fine filter from the pump
head.
Figure 9
Remove the system care reservoir.
Unscrew the top supply hose to the
swimmer container.
Figure 10
Connect the top supply hose at pump
head.
Replug the rinse line of the detergent
dosing valve.
Connect suction hose (minimum diame-
ter 3/4“) with filter (accessory) to the
water connection point.
–
Max. suck height: 0.5 m
Until the pump sucked in water, you should:
Set the pressure/quantity regulation at
the pump unit to maximum quantity.
Close the dosing valve for the detergent.
Danger
Never suck in water from a drinking water
container. Never suck in liquids which con-
tain solvents like lacquer thinner, petrol, oil
or unfiltered water. The sealings within the
device are not solvent resistant. The spray
mist of solvents is highly inflammable, ex-
plosive and poisonous.
Note:
Assembly in reverse order. Ensure
that the solenoid valve cable on the reser-
voir of the system care is not pinched.
–
For connection values, see technical
data and type plate.
–
The electrical connections must be
done by an electrician according to IEC
60364-1.
Danger
Danger of injury by electric shock.
–
Unsuitable extension cables can be
hazardous. Only use extension cables
outdoors which have been approved for
this purpose and labelled with a suffi-
cient cable cross section:
–
Always unwind extension lines com-
pletely.
–
The plug and coupling of the extension
cable used must be watertight.
