Sealing Ice Machine to Bin Top.
For machines installed on bins that do not have a drip pan, the perimeter of the ice machine
must be sealed with silicone. A tube of silicone sealant, and instructions are shipped inside the
ice machine for this purpose. (See FIGURE-4 and the instructions below)
1. Set machine on bin making sure that ice discharge chute is centered over bin
top opening.
2. Apply approximately 1/8” fillet bead of silicone to all sides of frame where it
meets bin top as shown in Detail “A”. NOTE: make sure that silicone bead on
frame does not interfere with proper casing fitup.

! WARNING !
The scroll compressor is phase sensitive. The compressor rotation must be checked before
the unit is operated. Failure to do so may affect compressor warranty.
! WARNING !
All electrical, water, drains, and air-cooled condenser connections are made at the rear of the ice
machine. See FIGURE-5 below for location information of all connecting points.

Wiring And Electrical Connection.
Only service personnel experienced in refrigeration and qualified to work with high
voltage electrical equipment should be allowed to install or work on the Tube-Ice®
Refer to TABLE-1 below to properly size wiring connections. A fused disconnect must be
provided near the Tube-Ice® machine. Connect 3-phase power to terminals L1, L2, L3 for
operation of the Tube-Ice® machine and its controls. (See FIGURE-6) If one leg of the 3 phase
power is higher or lower (“Wild”), then it should be connected to terminal #L2. Connect the
“Ground” wire to the “Ground” terminal provided. On dual voltage, 50 Hz machines, the 220V
single phase should be connected to terminals L4 and L5.
Note: When initially starting the machine, the scroll compressor must be phased properly. If
the compressor is run backwards for an extended period of time, the compressor may be
damaged.
208/230V Air-cooled condenser should be wired to terminals 20,21,22 and 23. (see FIG. 11 &
12). 460V air cooled condensers should be wired to terminals B1, B2, B3, 22 & 23.

Water Supply and Drains
The condenser water outlet, water tank drain, drip drain and ice storage bin drain connections
must be extended to an open drain or sump and arranged for visible discharge. See FIGURE-7
for water and drain connections on machine. See FIGURE-8 of typical space diagram drawing
for ice storage bin drain connection.
! 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.
! CAUTION !

Air-Cooled Condenser Installation Instructions
! WARNING !
These 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.
! WARNING !
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 airflow. Indoor condensers used for
heat recovery may be installed with either horizontal or vertical airflow.
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
Installation & Start-up – HES Series
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 R22 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.

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).
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.
