9. Place the crusher on a flat surface, Then stand the unit on its left side.

10. Position the bottom guard so that the right side flange is hung over the ice breaker bar.

11. Install the left side flange over the mounting studs and secure in place with the 1/4-20 lock nuts.

    • Note: Use care when positioning the ice crusher on the bin so that the guard is not damaged. Be sure to check for internal bin components such as deflectors, Dividers ETC., Which may interfere with the guard during installation.
    • CAUTION:
    • Adjust the bin thermostat to turn off the bin cuber before the ice level is above the guard screen. If ice is allowed to collect above the screen it will not clear when the ice below is removed.
    • This condition will cause ice to pile up in the chute of the crusher and ultimately, damage the cuber.
    • It should be understood that the use of the bottom guard will REDUCE the effective volume of the bin.
    • The crusher is designed to operate in conjunction with one or two Kold-Draft® cubers. Two motor control relay blocks are provided and a relay coil must be installed for each cuber used. Each relay coil must have a voltage rating matching the voltage of the ice cuber, regardless of the crusher motor voltage. The relay coils are installed through the opening in the control box. A third relay is provided for controlling one or two cubers 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.

12. 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. The ice maker safety switch must be mounted by the installer. (See illustration “D”)

    • If not provided, locate and drill two 3/16 inch dia. holes in the ice maker lower front rail. Mount the safety switch support with the #8-32 screws and nuts provided.
    • CAUTION
    • The safety switches DO NOT de-energize all circuits in the crusher or circuits in the ice maker. Before cleaning or servicing this equipment disconnect ALL power supplies.

13. Install a grommet in the 1-3/32 inch dia. hole in the ice maker condensing unit pan. Push the crusher control wire assemblies 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 cuber safety switch. (See Wiring Diagram)

15. Route the chrusher control wires along the right side of the partition wall to 7/8 inch hole located to the right of the contactor. Install a grommet in the hole and push the wires through.

16. The bin thermostat in the cuber must be disabled and replaced by the two thermostatic switches in the crusher. (See Wiring Diagram).

17. The crushed ice thermostat (Left) cap tube is placed into the straight thermostat tube holder. Push the cap tube into the flared end until the cap tube is visible at the straight end. Install the tube holder into the hole in the motor platform directly behind the crusher motor.

18. The cube ice thermostat (Right) cap tube is placed into the bent thermostat tube holder. Mount the tube holder as shown. (See Illustration “E”) Tighten the clamp screws. Adjust the thermostats to shut off the cuber approximately 1 minute after the ice contacts the tube holders.

19. The cube ice thermostat (right) cap tube is placed into the bent thermostat tube holder. Mount the tube holder as shown. (See Illustration “E”) Tighten clamp screws. Adjust thermostats to shut off the cuber approximately 1 minute after ice contacts the tube holders.

• Crushers are intended for indoor use only with permanent connection to a field electrical supply.
• All models are intended to be installed only in conjunction with Kold-Draft® cubers on Kold-Draft® bins.

CRUSHER OPERATION

• With the crusher knob in the “CRUSHED” position, ice falling from the cuber will be directed by the selector plate through the crusher mechanism and deposited into the left side of the bin.
• The crusher motor is powered through a relay which is energized by the hot gas valve circuit of the ice maker. The selector knob must be in the “CRUSHED” position to close a switch and complete the circuit to the motor. Additionally, the front panel safety switches must be depressed (covers on) for motor operation.
• With the crusher knob in the “CUBE” position, ice falling from the cuber will bypass the crusher mechanism and be dumped into the right side of the bin. The crusher motor will not be energized.

CLEANING

CAUTION:

• Risk of personal injury, equipment damage or contamination of the ice bin.
• Do not use ammonia solutions or strong detergents in cleaning the crusher.
• Never use appliance polishes, finish preservatives or cleaners in areas that could contact ice.

Disconnect power before cleaning or servicing the unit:

• Always clean the ice maker first, following the ice maker cleaning instructions.
• Remove all ice from the dispenser before starting the cleaning procedure.
• Clean and sanitize storage bin LAST.

1. Remove ice maker panels, ice chute, drain pan, crusher front panel and belt guard.
2. Wash interior with a solution of 2 tablespoons of baking soda per quart of clean water (140 deg. F. max.). The crusher ice hopper can be accessed from the front and left side of the ice cube. Use a long handled brush to clean inside the hopper, as crusher teeth can cause injury.
3. The bottom area of the crusher ice hopper can be accessed from inside the ice bin. Use a long handled brush.
4. Wipe down internal cabinet walls with a cloth soaked in cleaning solution.
5. Rinse with clean tap water.
6. Sanitize all ice contact surfaces with a solution of 1 teaspoon 5-1/4% sodium hypochlorite (chlorine bleach) per quart of clean tap water (minimum 100 PPM free chlorine). A spray bottle will facilitate this process.
7. Pour the remaining solution into the crusher chute, slowly, while rotating the cutter wheel by hand turning the pulley.
8. After adjusting and lubricating crusher (See following section), replace all enclosure panels and connect the electrical supply.
9. Exterior surfaces may be cleaned by standard methods suitable to the stainless steel finish.

ADJUSTMENT AND LUBRICATION
