14. 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.
15. The machine is shipped with a full operating charge of refrigerant sufficient to fill the condenser
and connecting lines. If the condenser piping is longer than 50 feet (one way), additional R-404a
may need to be added to retain enough refrigerant in the receiver for thawing purposes. Refer to
the operating level mark on the receiver and charge accordingly. Each 1” of liquid level in the
receiver equals approximately 11 pounds of R-404a.
16. 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).
17. 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:
a. Local electrical code must be checked for wiring method.
b. The installer must provide a disconnect switch(s) adjacent to the condenser.
c. Electrical connections between the condenser and the Tube-Ice
®
machine require
minimum 12 ga. wire.
d. All electrical fittings and components exposed to the weather must be suitable for
outdoor installation.
