Connect the water supply hose (the hose marked blue) to the cold water valve.

Turn on the valve and check for leaks. The water pressure must be within

15-145 psi (1-10 bar). If the water pres- sure is greater than 145 psi

(10 bar), a pressure reducer must be installed. If the water pressure is below 15 psi (1 bar), insufficient water may be available for a complete fill.

The water supply hose is equipped with a filter; please do not remove this filter.

Connection to the drain sys- tem.

The 5 ft. (1.5m) drain hose may be con- nected as follows:

1.Directly into a sink: hook the hose over the edge of the sink and secure it firmly (e.g. by tying the hose to the water faucet).

2.To a stand pipe: place the drain hose

into a 1 1/2“ (38 mm) stand pipe and firmly secure it.

3.To a floor drain: The machine is equipped with an airgap/anti-siphon- ing system so that no minimum drain height is required.

The machine drains using a pump with a maximum delivery height of 4 ft. (1.2 m).

Make sure there are no kinks in the drain hose.

If desired, the drain hose may be ex- tended to 15 ft. (4.5 m) maximum.
