Product Description:
This ice machine is designed to be used indoors, in
a controlled environment or outdoors within certain
limits.
The NU130 is made up of two major systems: the
ice making system and the ice storage system. The
ice making system is a continuous flow type ice
machine, it makes ice when the ice level becomes
low and stops when it is full.
The ice storage system is an insulated chest with a
drain at the bottom for melting ice. It is not
refrigerated, insuring that the bin contains fresh ice.
Installation Information
Dimensions:
The cabinet is fourteen and seven eighths inches
wide by thirty three and three eighths to thirty four
and three eighths inches high.
Utility and Operational Requirements
•The NU130 must be connected to a potable
water supply.
•The water supply must have a conductivity of
at least 10 microSiemens/cm.
•Minimum water pressure: 20 psi
•Maximum water pressure: 80 psi
•Minimum water temperature: 40 degrees F.
•Maximum water temperature: 90 degrees F.
It is designed to operate in wide range of air
temperatures:
•Minimum air temperature: 50 degrees F.
•Maximum air temperature: 100 degrees F.
Although the machine will function within the listed
ranges, it works best at water temperatures
between 50 and 60 and air temperatures between
60 and 80.
Note: Ice making capacity goes down as the
environmental temperatures go up, and will be
severely reduced at temperatures over 90oF.
Operating a unit outside of the limits can cause
problems that are not covered by the warranty and,
if extreme, cause damage to the unit.
Water Quality
The water to the machine must be potable, or fit for
human consumption. Beyond that, water supplies
vary in the degree of mineral content. As this ice
machine makes ice, all the water that flows into the
machine is changed into ice. That includes any
minerals that might be in the water. However,
during ice making some minerals will stick to the
ice making components. The higher the mineral
content, the more mineral build up will occur. Water
filters are a partial help, as they will remove the
suspended solids, but water treatment is needed
for the dissolved solids, which are part of the water
and cannot be filtered out.
RO Water
This machine can be supplied with Reverse
Osmosis water, but the water conductivity must be
no less than 10 microSiemens/cm. A reverse
osmosis system should include post treatment or
blending to satisfy the R.O. water’s potential
aggressiveness.
Deionized water is not recommended and could
damage the machine.
Because water softeners exchange one mineral for
another, softened water may not improve water
conditions when used with ice machines
Electrical power
The unit must be on its own 115 volt, 60 Hz, 15
amp circuit. It is equipped with a power cord and
can be plugged into a nearby outlet. Extension
cords are not allowed by most codes. Follow all
applicable codes.
Warranty Information
Warranty information is supplied separately from
this manual. Refer to it for coverage. In general, the
warranty covers defects in materials or
workmanship and does not cover corrections of
installation errors or maintenance.
