installed, fi lter bottom should be at least 2 1/2” from sink 
cabinet fl oor to facilitate fi lter change.  Install screws, but 
only halfway, so you can easily slip the bracket to wall

 • 

The drinking water system faucet should be located on a fl at surface, conveniently located near the sink, so that it 

empties into the sink.  Most sinks have pre-drilled holes designated for sprayers, soap dispensers, and other ac-
cessories.  If your sink does not have an extra hole, 

we highly recommend professional installation.

 • 

Porcelain, enamel, and ceramic sinks require special procedures for drilling holes.  

Professional installation is 

highly recommended.  (See page 6)

IMPORTANT NOTES

To reduce the risk of eye injury while drilling countertop for faucet installations:
 • 

Safety glasses 

MUST

 be worn during the sink hole drilling operations.
