Air-Cooled Condenser
Installation Instructions

HES Series Air-Cooled Installation Instructions
These installation guidelines must be followed to obtain reliable operation from
air-cooled ice machines. If these guidelines are not followed, the compressor
1. Use only Vogt approved condensers. Any exceptions to this policy must be obtained in writing
prior to installation and operation of the ice machine.
2. 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.
3. The condenser must be mounted 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.
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-10. Long vertical runs should have traps every 20 feet.
8. Use only ACR grade copper pipe, Type L. Recommended line sizes are shown in TABLE-3.
9. Distance between ice machine and condenser must not exceed 150 equivalent feet. Refer to
Condenser Equivalent Line Size worksheet. (see TABLE-5)
10. Condensers must be provided with a cold weather valve kit per FIGURE-9A. 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. The coil thermostat should be set to close at 35?F. for multiple fan condensers or 50?F for single fan condensers.
11. Condensers with multiple fans must be provided with a thermostat to turn off unneeded fans in
cold weather. Turning off unneeded fans reduces on-off cycling of the fan(s) and allows for a steadier condensing pressure. The fan thermostat should be set at 50?F.
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. 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. 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.
TABLE - 3
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-2. 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 105?F, consult the factory about using a larger condenser.
