information concerning care and maintenance for your new sink.
·Place the template on the counter, in the location where you will be installing the sink. When
placing the template, note the location of cabinet doors and panels to ensure that they are
compatible with sink installation. Make sure that there is enough space for water supply installation.
Identify the location of the faucet and soap dispenser.
·Fix the template to the counter using masking tape.
·Trace the inside of the template with a pencil. Remove the template from the countertop.

and shattered fragments caused by the jigsaw.
·Using the jigsaw, trim the inside of the cutting line.
·Insert the sink and adjust the opening if necessary.
! CAUTION - To avoid the risk of personal injury, wear safety glasses and cut resistant gloves with
