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
from Vogt 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.
NOTE: Condenser must be ordered for horizontal air flow.
3. The condenser must be mounted above the ice machine.
4.
Horizontal runs in the liquid return line should slope 1/4” per foot with liquid refrigerant
draining freely in the direction of normal operating flow (back to the ice machine) with no traps
in the liquid line.
5.
Horizontal runs in the discharge line should slope 1/4” per foot in the normal direction of flow
(away from the ice machine).
6.
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. Long vertical rises
should have traps every 20 feet. Typical details are shown in FIGURE 3-6.
7. 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.
8. The discharge and liquid lines must be insulated with 1/2” thick Armaflex insulation or equal.
9. Use only ACR grade copper pipe, Type L. Recommended line sizes are shown in TABLE 3-3.
10. For field attachment instructions, see FIGURE 3-4.
11.
Distance between ice machine and condenser must not exceed 150 equivalent feet. Refer to
Condenser Equivalent Line Size worksheet (see TABLE 3-5 ).
12.
Condensers must be provided with a cold weather valve kit per FIGURE 3-5. These valves
allow one-half of the condenser to be disabled in cold weather. Running the ice machine with
one-half of the condenser in cold weather makes it easier to maintain minimum necessary
condensing pressure particularly in windy conditions.
13. 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 and more consistent warm gas for ice harvesting.
