The faucet may be mounted on the sink using an existing hole for a sprayer nozzle or
soap dispenser, or by drilling a hole at least 1/2" in diameter. Be sure the location of the
faucet allows the spout to extend slightly past the edge of the sink. Note: we recommend
enlisting the services of an approved or certied professional if drilling is required.

Installation must comply with state and local laws.
The HF-2STAGE and HF-3STAGE are available in two
