Wiring And Electrical Connection.
! WARNING !
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
®
machine.
! WARNING !
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.
