HEC-Series Service Manual
A Brief History Of Our Company. Henry Vogt Machine Co. was founded as a small
machine shop in Louisville, Kentucky in 1880. Today, Vogt Tube Ice, LLC 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 much
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, TubeIce® 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 the HEC model Tube-Ice® machines. Since Vogt introduced TubeIce® 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 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 which 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 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. Also, make sure the Warranty Registration/Startup Report is completed and returned.
If you have additional questions, please call your distributor. Also, feel free to phone the

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 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
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
HCFC-22 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.
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, overfilling it, and possibly causing the cylinder to rupture because of pressure from
expansion of the liquid refrigerant brought on by an increase in temperature.
Always store cylinders containing refrigerant in a cool place. They should never be exposed
to temperatures higher than 125°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.
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.

When the ice machine sits on a storage bin, the bin must be provided with a drip pan for catching the
condensate from the ice machine. Separate drains for the condensate and for the bin are necessary.
See FIGURE 3-4 or 3-5 (space diagram drawings for typical water and drain connections).
Condensate drain must not run through the ice compartment of the bin.
The condenser water outlet, water pan drain, condensate drain and ice storage bin drain connections
must be extended to an open drain or sump and arranged for visible discharge.
! CAUTION !
These lines must NOT be connected into a pressure tight common header
due to the possibility that warm condenser water
may back up into the water pan, drip pan or the ice storage bin. The
condenser water outlet MUST be piped separately to the drain.

Air-Cooled Condenser Installation Instructions.
Using a non-Vogt condenser will void the compressor warranty.
Certain installation guidelines must be followed to obtain reliable operation from air-cooled ice
machines. If these guidelines are not followed, the compressor warranty will not be honored. Any
exceptions to this policy must be obtained in writing prior to installation and operation of the ice
machine.
1. Outdoor condensers must be installed with vertical air flow. Indoor condensers used for heat
recovery may be installed with either horizontal or vertical air flow.
2. The preferred condenser location is above the ice machine, with liquid refrigerant from the
condenser outlet draining freely (1/4” per foot slope) in the direction of normal operating flow
(back to the ice machine) with no traps in the liquid line.
3. If it is absolutely necessary to install the condenser below the ice machine, certain conditions
MUST be met. The refrigerant connections on the condenser must be no more than 6 feet below
the refrigerant connections on the ice machine. The return liquid line from the condenser must
rise no more than 12 feet before dropping back down to the elevation of the ice machine. When
the condenser is located below the ice machine, expect a 16 psig increase in head pressure and at
least 3% reduction in capacity.
4. Flooding head pressure controls such as Alco Headmaster are not to be used, since they cause
excessive subcooling of the returned liquid refrigerant and interfere with reliable ice harvest.
5. The discharge and liquid lines must be insulated with 1/2” thick Armaflex insulation or equal.
6. Horizontal runs in the discharge line should slope 1/4” per foot in the normal direction of flow
(away from the ice machine).
7. Traps must be installed in discharge lines at the base of all vertical risers. There should be no
intentional traps in liquid lines. Trap volume should be kept to a minimum. Typical details are
shown in FIGURE 3-8.
8. Use only ACR grade copper pipe, Type L. Recommended line sizes are shown in TABLE 3-2.
9. Distance between ice machine and condenser must not exceed 150 equivalent feet. Refer to
Condenser Equivalent Line Size worksheet.
10. Condensers must be provided with a cold weather valve kit per FIGURE 3-7. These valves
allow one-half of the condenser to be disabled in cold weather. Running the ice machine with
one half the condenser in cold weather makes it easier to maintain minimum necessary
condensing pressure, particularly in windy conditions.

11. Condensers with multiple fans must be provided with a thermostat to turn off unneeded fans in
cold weather, per FIGURE 3-9. Turning off unneeded fans reduces on-off cycling of the fan(s)
and allows for a steadier condensing pressure.
12. When extreme cold conditions are expected or encountered (temperatures below 0°F and wind
greater than 15 MPH), it may be necessary to install a protective enclosure around the condenser.
A typical enclosure is shown in FIGURE 3-12. Other apparatuses such as louvers may be used.
Contact the factory for suggestions.
13. After installation, the field-installed lines are to be evacuated to a vacuum of 500 microns or less
and held for at least one hour. After the vacuum pump is removed, vacuum should hold at 500
microns or less for at least 5 minutes and the lines pressurized with R-22 to 25 psig minimum.
14. The volume of refrigerant supplied with the machine is sufficient to fill the condenser and
condenser lines when length of pipe (one way) is 75 feet or less. When the length of lines is
longer than 75 feet, additional refrigerant must be added as follows:
Liquid Line Size
1/2” none none none 2
5/8” none 2 4 6
7/8” none 4 8 12
1-1/8” none 6 12 18
15. All piping must be done in accordance with applicable local and national codes. Such codes may
include “The Safety Code for Mechanical Refrigeration (ANSI B9.1), and “The Code for
Refrigerant Piping” (ANSI B31.5).
The following installation guidelines are strongly suggested. While they do not affect the machine
warranty, they may be required for safe operation, and to comply with all applicable electrical and
mechanical codes.
16. Local electrical code must be checked for wiring method.
17. The installer must provide a lockable, fused disconnect switch(s) adjacent to the condenser.
18. Electrical connections between the condenser and the Tube-Ice® machine require minimum 12 ga.
wire.
19. All electrical fittings and components exposed to the weather must be suitable for outdoor
installation.
The design total heat rejection for each Tube-Ice® machine, the recommended air-cooled condenser,
and condenser physical and electrical data are shown in TABLE 3-3. Only the condensers shown are
UL listed with the ice machines. Other condensers may be individually UL listed, but are not UL
listed with the Tube-Ice® machines, and cannot be recommended by the Henry Vogt Machine Co.

Catalog energy efficiency ratings of the ice machines are based on use of the recommended
condenser.
Condensers supplied by Vogt must be utilized. The use of non-Vogt condensers will void the
compressor warranty. For continuous operation at ambients above 105°F, consult the factory about
using a larger condenser.
