the front of the dispenser. There are two different baffle
kits available for “S” series ice machines, one kit is for
the 30" wide machine, and the other kit is for the 22"
wide machine. There is also a kit for “Q” series ice
machines.

Location
The location selected for the beverage dispenser must
meet the following criteria. If any of these criteria are not
met, select another location.
• The air temperature must be at least 50°F (10°C), but
must not exceed 95°F (35°C).
• The location must not be near heat-generating
equipment or in direct sunlight and must be protected
from weather.
• The countertop must be level. Verify that the
countertop can support the weight of the dispe ns er,
or the dispenser/ice machine combination plus the
weight of the stored ice.
• Water lines, drains and power outlet must be within 6'
(1.8 m) of location.

area before repairing the leak. CO
must not be installed in an enclosed space. An
enclosed space can be a cooler or small room or
closet. This may include convenience stores with
