1. Introduction
Vogt Ice, L.L.C.
A Brief History Of Our Company. Vogt Ice, L.L.C. (formerly Henry Vogt Machine Co.) was
founded as a small machine shop in Louisville, Kentucky in 1880. Today, it is one of the world’s
leading producers of ice-making equipment.
In 1938, Vogt built the first Tube-Ice
®
machine and revolutionized the ice-making industry. Our first
“sized-ice” machine quickly replaced the old can-ice plants, which required hard labor and large
amounts of floor space for freezing, cutting, and crushing ice by hand.
Vogt Energy-Saving Tube-Ice Machines Are Cost Effective. Today, Vogt Tube-Ice
®
machines
enjoy a well-earned reputation as the most energy efficient, dependable ice-making equipment in the
world.
Using as little as one-half to one-third the energy required by competitors’ ice makers, Tube-Ice
®
machines produce the same amount of ice--in restaurants, sports arenas, packing plants, and
wholesale operations around the globe--at great savings.
In addition, Tube-Ice
®
machines are renowned for their long life, giving many customers more than
35 years of dependable service. Ask someone who owns one.
Preview. All the skill in engineering and fabrication that we’ve learned in over a century of
experience is reflected in every Tube-Ice
®
machine. Since Vogt introduced Tube-Ice
®
machines in
1938, the process of making Tube-Ice
®
ice has been widely recognized as the most economical
means of production. The machine’s economic and reliable operation has been proven over and over
again, in a network of varied types of installations throughout the world.
Furnished with your machine is the Certificate Of Test--the report of operating data that is a record
of the unit’s satisfactory operation at our factory test floor. It is evidence of our desire to deliver to
you “the finest ice-making unit ever made.”
This manual is designed to assist you in the installation, start-up, and maintenance of your unit.
Your Tube-Ice
®
machine will give you a lifetime of service provided you install, maintain, and
service it properly.
Please read your manual carefully before attempting installation, operation, or servicing of this
professionally designed piece of equipment. Also, make sure the Warranty Registration/Start-up
Report is completed and returned.
If you have additional questions, please call your distributor. Also, feel free to phone the factory
direct at [phone].

Important Safety Notice. This information is intended for use by individuals possessing adequate
backgrounds in electrical, refrigeration and mechanical experience. Any attempt to repair major
equipment may result in personal injury and/or property damage. The manufacturer or seller cannot
be responsible for the interpretation of this information, nor can it assume any liability in connection
with its use. It is important that personnel understand the properties of this refrigerant and that they
be thoroughly trained in safe practices for its use and handling. Refer to the enclosed “Anhydrous
Ammonia Safety” in Appendix A.
Safety Symbols & What They Mean. Prior to installation or operation of the Tube-Ice
®
machine,
please read this manual. Are you familiar with the installation, start-up, and operation of a Tube-Ice
®
machine? Before you operate, adjust or service this machine, you should read this manual,
understand the operation of this machine, and be aware of possible dangers.
These safety symbols will alert you
when special care is needed.
Please heed them.
! DANGER !
Indicates an immediate hazard and that special precautions
are necessary to avoid severe personal injury or death.
! DANGER !
! WARNING !
Indicates a strong possibility of a hazard and that an
unsafe practice could result in severe personal injury.
! WARNING !
! CAUTION !
Means hazards or unsafe practices could result
in personal injury or product or property damage.
! CAUTION !

Special Precautions To Be Observed When Charging Refrigeration Systems. Only technically-
qualified persons, experienced and knowledgeable in the handling of anhydrous ammonia refrigerant
and operation of refrigeration systems, should perform the operations described in this manual. All
local, federal, and EPA regulations must be strictly adhered to when handling ammonia (R-717)
refrigerant. See “Material Safety Data Sheet”, MSDS Code No. 5B81-83.
If a refrigeration system is being charged from refrigerant cylinders, disconnect each cylinder when
empty or when the system is fully charged. A gage should be installed in the charging line to
indicate refrigerant cylinder pressure. The cylinder may be considered empty of liquid R-717
refrigerant when the gauge pressure is 25 pounds or less, and there is no frost on the cylinder. Close
the refrigerant charging valve and cylinder valve before disconnecting the cylinder. Loosen the
union in the refrigerant charging line--carefully to avoid unnecessary, excessive or illegal release of
refrigerant into the atmosphere.
! CAUTION !
Immediately close system charging valve at commencement of defrost or thawing cycle if
refrigerant cylinder is connected. Never leave a refrigerant cylinder connected to system
except during charging operation. Failure to observe either of these precautions can result in
transferring refrigerant from the system to the refrigerant cylinder, over-filling it, and
possibly causing the cylinder to rupture because of pressure from expansion of the liquid
refrigerant brought on by an increase in temperature.
! CAUTION !
Always store cylinders containing refrigerant in a cool place. They should never be exposed to
temperatures higher than 120°F and should be stored in a manner to prevent abnormal mechanical
shocks.
Also, transferring refrigerant from a refrigeration system into a cylinder can be very dangerous and is
not recommended.
! CAUTION !
It is not recommended that refrigerant be transferred from a refrigeration system directly into
a cylinder. If such a transfer is made, the refrigerant cylinder must be an approved, CLEAN
cylinder--free of any contaminants or foreign materials--and must be weighed continuously to
assure contents do not exceed net weight specified by cylinder manufacturer or any applicable
code requirements.
! CAUTION !
