Notes:
• The crusher is designed to operate in conjunction with one or two KOLD-DRAFT
®
ice
makers. Two motor control relay blocks are provided and a relay coil must be installed for
each ice maker used. Each relay coil must have a voltage rating matching the voltage of
the ice maker, regardless of the crusher motor voltage. T271 crushers are supplied with
115V relays. T274 crushers are supplied with 208-230V relays. The relay coils are
installed through the opening in the control box. A third relay is provided for controlling one
or two ice makers with the same set of bin thermostats. This relay coil voltage rating is
matched to the crusher motor voltage and is provided with the crusher.
• A dual safety switch system is employed in the crusher design to break the circuit to the
motor. If either the front panel of the crusher or the front panel of the bottom ice maker is
removed, a switch will open the motor circuit. The crusher safety switch is mounted in the
crusher control box.
12. Install a grommet in the pre-cut hole in the floor of the ice maker’s compressor compartment
directly behind the controller box.
13. Push the safety switch wire assembly (wires with insulated 90 ° flag terminals) and the motor
control wire assembly (wires with piggyback terminals) through the grommet into the ice
maker
14. Connect the safety switch wires from the crusher to the "Common" and "Normally Open"
terminals of the ice maker safety switch (the two outer terminals). (See Wiring Diagram)
Note: There are two motor control wire assemblies of different lengths. When using a stacked
machine the shorter wire assembly gets connected to the lower ice maker and the longer wire
gets connected to the upper ice maker. If the ice maker is not a stacked unit the longer wire is
unused
