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. Use ¼” access connection located on compressor
discharge line and liquid return line (32). 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 noted below. Instructions
for adding refrigerant are included further in these instructions.

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).
16. 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.
17. Local electrical code must be checked for wiring method.
18. The installer must provide a lockable disconnect switch(s) adjacent to the condenser. The
power is fused at the machine by a 15 amp breaker.
19. Electrical connections between the condenser and the Tube-Ice ® machine require
minimum 12 ga. wire. See FIGURE-11 &12.
20. 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-4. 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
Vogt Tube-Ice. 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 ambient above 95
°
F, consult the factory
about using a larger condenser.
