NOTES
• If air temperature is less than 60°F (16°C), water temperature must be equal to or greater than 50°F (10°C).
• Plumbing must conform to state and local codes.
• Although the ice machine has been designed to be serviced in place, in some cases it may be necessary to pull
the unit out for service. For that reason do not restrict access to the unit at the front, top and bottom. If a floor is
to be installed after the ice machine, shims the thickness of the floor should be installed under the unit to keep the
ice machine level with the floor. Also, allow 1/8" (3) clearance on each side of the unit for protruding screw heads.
Installations on a Cement Slab:
Use a Model UC-15IPO or UC-15IP, with built-in drain pump and pump the water to the point of drainage. Drain
pump models will pump 12 feet (3.7 m) high.
Installations Over a Crawl Space or Basement:
If there is not enough room behind the ice machine for a drain/waste water receptacle, the drain will have to be
below the floor.
