FOR THE INSTALLER: Final Check List

1. Is the icemaker-dispenser installed indoors, in a
location where the air and water temperatures are
controlled, and where they do not go beyond
design limitations?

2. Is there an electrical service disconnect within
sight of the installed machine? Is the machine on a
separate circuit? Has the voltage been checked
and compared to nameplate requirements?

3. Have all of the plumbing connections been
made and checked for leaks?

4. Has the machine been leveled?

5. Is there a minimum of 6 inches of clearance at
the left and right sides of an air cooled machine?

6. Is there a minimum of 6 inches of clearance at
the top and back of the machine for service and
utility connections?

Wall mounted only: Is the machine properly

installed and secured to the wall?

7. Is there a water shut off valve installed near the
machine?
