Do you have a question about the Hoshizaki FM-AKE Series and is the answer not in the manual?

Overview

This document outlines the procedure for replacing bags in the Hoshizaki FM-AKE Series ice machines, focusing on wiring protection methods and the number of bags required for various models. The FM-AKE Series appears to be a range of commercial ice makers, likely producing flake or nugget ice, given the "bags" mentioned in the context of wiring protection, which typically refers to protective sleeves or covers for electrical connections.

Function Description

The primary function of the FM-AKE Series is to produce ice. While the specific type of ice (e.g., flake, cube, nugget) is not explicitly stated, the context of "bags replacement" for wiring protection suggests a design where electrical components are susceptible to moisture or environmental factors, necessitating protective measures. The document focuses on the maintenance aspect of these protective bags, which are crucial for the safe and reliable operation of the ice maker by shielding electrical connections.

Important Technical Specifications

The document does not directly list technical specifications such as ice production capacity, power consumption, or dimensions. However, it provides a comprehensive table detailing various models within the FM-AKE Series and their bag requirements. This table implicitly indicates the range of models covered by this maintenance procedure.

Model Codes and Bag Requirements:

The table categorizes models by Model code and Model Name, specifying the number of bags required for Picture_A (Top View) and Picture_B (Around CM) locations, along with a sum of bags.

  • FM-750AKE-SB / FM750AKER452SB / FM750AKER452NSB: These models require 1 bag in the Picture_B (Around CM) location, with N/A for Picture_A (Top View), totaling 1 bag. This suggests a simpler wiring configuration or fewer exposed connections requiring protection in the top view area for these specific models.
  • FM-600AKE-N-SB / FM-600AWKE-SB / FM600AKER452SB / FM600AKER452NSB / FM600AWKER452NSB / FM-600AKE(SA): These models consistently require 3 bags in the Picture_A (Top View) location and 1 bag in the Picture_B (Around CM) location, totaling 4 bags. This indicates a more complex internal wiring layout or a greater need for protection in multiple areas.
  • FM-170AKE-SB / FM-170AKE-N-SB: These models require 2 bags in the Picture_A (Top View) location, with N/A for Picture_B (Around CM), totaling 2 bags. Similar to the 750AKE series, this suggests a focus on top-view wiring protection.
  • FM-480AKE-HC-SB / FM-480AKE-HCN-S-SB / FM-480AKE-HCN-SB: These models require 3 bags in the Picture_A (Top View) location and 1 bag in the Picture_B (Around CM) location, totaling 4 bags.
  • FM-300AKE-HC-SB / FM-300AKE-HCN-SB: These models require 3 bags in the Picture_A (Top View) location and 1 bag in the Picture_B (Around CM) location, totaling 4 bags.
  • FM-150AKE-HC-SB / FM-150AKE-HCN-SB: These models require 2 bags in the Picture_A (Top View) location, with N/A for Picture_B (Around CM), totaling 2 bags.
  • FM-600ALKE-CO2-SB / FM-600ALKE-CO2N-SB: These models require 2 bags in the Picture_A (Top View) location and 1 bag in the Picture_B (Around CM) location, totaling 3 bags. The "CO2" in the model name suggests these are CO2-refrigerant based units, indicating a commitment to environmentally friendly refrigerants.
  • FM-1200ALKE-CO2-SB / FM-1200ALKE-CO2N-SB: These models require 3 bags in the Picture_A (Top View) location and 1 bag in the Picture_B (Around CM) location, totaling 4 bags. These are also CO2-refrigerant based units, likely with higher production capacities given the "1200" in the model name.

The part number for the plastic bag is 4X1559-07, and the cable tie is 150mm.

Usage Features

The document primarily focuses on maintenance rather than daily operational usage. However, the existence of these protective bags implies that the FM-AKE Series ice makers are designed for environments where electrical connections need robust protection from moisture, dust, or other contaminants, which is typical for commercial kitchen or food service settings. The use of CO2 as a refrigerant in some models highlights a feature geared towards environmental responsibility and potentially energy efficiency.

Maintenance Features

The document is a detailed guide for a specific maintenance task: replacing protective bags for wiring.

Key Maintenance Steps:

  1. Preparation: Gather necessary tools: screwdriver, diagonal pliers, cable tie, tube, and plastic bag (part number 4X1559-07).
  2. Safety First: Disconnect the power supply by unplugging the power cord before starting any work. This is a critical safety instruction.
  3. Access: Remove the front and top panels of the ice maker to gain access to the internal components.
  4. Locate and Replace Bags:
    • Identify bags in Picture_A (top view) and Picture_B (on the base next to the compressor).
    • Replace bags one by one with tubes and secure them with cable ties. It is crucial not to remove all bags at once to avoid confusion with wiring.
    • If any model has fewer bags than specified in the table, additional bags should be fitted to the designated locations.
  5. Reassembly: Re-fit the control box cover and front panel after completing the bag replacement.
  6. Power Connection: After all work is done, connect the power supply and energize the unit.

Wiring Protection Methods (Reference):

The document provides three methods for protecting wiring, to be used if new bags are unavailable or as alternative methods. The preferred method is using new bags.

  • a. In the case of using "new bag":

    • Place terminals inside the new bag.
    • Tie the bag with a 150mm cable tie (part number 4X1559-07). This is the standard and recommended method.
  • b. In the case of using "tapes" (alternative):

    • Bundle cables together with a cable tie, trimming any excess.
    • Apply insulation tape vertically over the terminal, ensuring the top of the terminals is covered.
    • Wrap insulation tape around the wire bundles (BOMs) as shown in the diagram.
    • Ensure the BOMs are fully covered with minimal gaps at the top and bottom. This method provides a secure, moisture-resistant seal using tape.
  • c. In the case of using "tubes" (alternative):

    • Prepare a UL tube (Underwriters Laboratories certified tube).
    • Insert the terminal inside the tube.
    • Fold the tube in half. If the tube is too long, cut it to an appropriate length.
    • Place the tube over the terminals and secure the bottom of the tube with a cable tie. This method uses a pre-formed protective tube for insulation.

The maintenance instructions are clear, step-by-step, and emphasize safety and proper technique, ensuring that the ice maker's electrical system remains protected and functional after servicing. The provision of alternative wiring protection methods demonstrates flexibility in maintenance, especially if specific parts are not immediately available. The detailed table of models and bag counts is a valuable resource for technicians to ensure correct and complete maintenance for each specific unit.
