Hans Grohe 06888XX0, 06890XX0 Installer Notes, Backflow Prevention, Remove the old showerhead

Installer Notes

These installation instructions show that water will be furnished through an existing shower arm. This is not the only installation possible. A Hansgrohe 27454XX1 or equivalent wall supply may also be used.

The screws and anchors included with this set are suitable for use in a tile or other solid-surface wall. They are not suitable for use in an acrylic or fiberglass shower enclosure. Please contact the manufacturer of the enclosure regarding recom- mended mounting locations, reinforcement requirements, and recommended mounting hardware.

Backflow Prevention

A backflow preventer (or vacuum breaker) is required by many local plumbing codes to protect your drinking water from back siphonage.

Hansgrohe recommends the use of external vacuum breaker 06510000 if backflow prevention is not provided by another device, such as a 27458XX1 wall outlet with integral vacuum breaker.

Remove the old showerhead

•While holding the shower arm, remove the existing showerhead by turning counter-clockwise with an

adjustable wrench.

• Thoroughly clean the threads on the shower arm with a wire brush.
