1. Introduction
TURBO REFRIGERATION CO.
A Brief History Of Our Company Henry Vogt Ice Machine Co. was founded as a small machine
shop in Louisville, Kentucky in 1880. 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 much hard labor and large amounts of floor space for freezing, cutting,
and crushing ice by hand.
Today, TUBE ICE

, LLC carries on the tradition as one of the world’s leading producers of ice-
making equipment.
Preview All the skill in engineering and fabrication that we have learned in over a century of
experience is reflected in the Modular Plate Ice Machine. Since Vogt Ice 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 operations have 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 on 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 modular plate ice machine will give you a lifetime of service when you install it, maintain it,
and service it properly.
Please read your manual carefully before attempting installation, operation, or servicing of this
professionally designed piece of equipment.
If you have additional questions, please call your distributor. Also, feel free to phone the factory
direct at [phone] or 1-800-853-8648.

Important Safety Notice. This information is intended for use by individuals possessing adequate
backgrounds of electrical, refrigeration and mechanical experience. Any attempt to repair major
equipment may result in personal injury and 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.
Special Precautions To Be Observed When Charging Refrigeration Systems. Only technically
qualified persons, experienced and knowledgeable in the handling of anhydrous ammonia refrigerant
(Appendix A contains the MSDS for R-717) 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 refrigerants. 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 and 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.
! 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 connected to an
approved recovery mechanism with a safety shutoff sensor to assure contents do not exceed net
weight specified by cylinder manufacturer or any applicable code requirements.
! CAUTION !

2. Receipt Of Your Vogt Ice Machine
! CAUTION !
Only service personnel experienced in ammonia refrigeration and
qualified to work on high amperage electrical equipment should
be allowed to install or service this Turbo Refrigerating machine.
Eye protection should be worn by all personnel
working on or around the Turbo Refrigerating machine.
It is very important that you are familiar with and adhere to
all local, state, and federal, etc. ordinances and laws regarding
the handling, storing, and use of anhydrous ammonia.
An approved ammonia mask should be readily available
for use in an emergency and all personnel should be aware
of its location and proper use.
! CAUTION !
Inspection As soon as you receive your machine, inspect it for any damage. If damage is suspected,
note it on the shipper’s papers (i.e., the trucker’s Bill of Lading). Immediately make a separate
written request for inspection by the freight line’s agent. Any repair work or alteration to the
machine without the permission of the Vogt Ice, LLC can void the machine’s warranty. You should
also notify your Vogt distributor or the factory.
Description Of Machine A Vogt Ice Modular low side machine is a remote ice producing plant
requiring refrigerant suction connection, refrigerant liquid connection, thaw gas connection, make-up
water supply, electrical connection, and the proper refrigerant charge.
The machine has been partially factory tested prior to shipment and will require adjustment to meet
the high side (condenser unit) operating conditions. See Start-up and Operation for the correct
setting of the controls.
The machine is evacuated and charged with nitrogen gas pressure for shipment. This prevents air or
moisture from entering the system during transit. There should be a positive pressure (20-25 psig)
indicated on the freezer pressure gage when the machine is received. The machine has been cleaned
with ice machine cleaner and flushed so that the machine is ready for ice production.
Safety Tags and Labels Be sure to read and adhere to all special tags and labels attached to valves
or applied to various areas of the machine. They provide important information necessary for safe
and efficient operation of your equipment.
Safety Valves This equipment is provided as a component of a larger refrigeration system. As such,
pressure safety valves are not provided from the factory. The end user bears the responsibility of the
proper sizing, selection, installation, and maintenance of pressure safety devices. Sizing must be to
the appropriate industry, local, and national codes, and must not allow the pressure in the equipment
to exceed 110% of MAWP. Vent the pressure relief valves to the atmosphere in such a manner as to
comply with industry, local, and national codes.
