 DANGER
Risk of personal injury or damage! Never suck in water
from a drinking water container. Never suck in liquids
which contain 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 in-
flammable, explosive and poisonous.
Note: Assembly in reverse order. Ensure that the sole-
noid valve cable on the reservoir 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 NEC and local codes.
HDS 5.0 only:
 DANGER
Risk of injury on account of electric shock!
– Unsuitable electrical extension cables can be haz-

doors which have been approved and labelled for
this purpose and have an adequate cable cross-
section.
– Always unwind extension lines completely.
– The plug and coupling of the extension cable used
must be watertight.
HDS 3.5, 4.0, 4.5 only:
 STEP 1: Plug the Ground Fault Circuit Interrupter
(GFCI) into a working outlet.
