This document is a cleaning and sanitizing manual for an automatic ice-cube maker, specifically the IC 24 model. It is intended for authorized maintenance personnel only and emphasizes that reproduction of the manual is strictly forbidden.
Function Description:
The device is an automatic ice-cube maker, model IC 24. Its primary function is to produce ice cubes. The manual focuses on the maintenance aspects, specifically cleaning and sanitizing, rather than detailed operational instructions. It is designed to ensure the hygienic operation of the appliance.
Important Technical Specifications:
The manual does not provide specific technical specifications such as power consumption, dimensions, or ice production capacity. However, it does mention components like the evaporator, pump, pump basin, sprayer bank, flag support assembly, ice-cube slide, and overflow pipe, which are integral to its ice-making and water circulation functions. The timer regulation screw is also mentioned, indicating a control mechanism for operation cycles.
Usage Features:
The manual primarily details maintenance procedures rather than daily usage features. However, some operational aspects are mentioned in the context of cleaning:
- Ice Production Cycles: The cleaning process involves operating the appliance for multiple one-minute periods with five-minute intervals, indicating a cycle-based operation for ice production.
- Timer Control: The appliance has a timer, which can be adjusted with a flat-head screwdriver. This timer likely controls the ice-making cycles and defrost functions. The manual instructs to adjust the timer if the pump is not operating during cleaning cycles, ensuring the indicator on the pin exits the "DEFROST" zone.
- Ice Storage: The presence of an "ice container" and instructions to "remove all ice from container" imply an internal storage bin for produced ice.
- Water Circulation: The pump is a critical component, responsible for spraying water during cleaning and sanitizing cycles, indicating a water circulation system for ice formation.
Maintenance Features:
The manual is entirely dedicated to the cleaning and sanitizing of the ice-cube maker, outlining a comprehensive set of procedures for authorized maintenance personnel. Key maintenance features and recommendations include:
- Frequency: Cleaning and sanitizing operations should be performed at least once a month. The frequency can vary based on environmental conditions, water quality (hardness, grit), quantity of ice produced, and periods of non-use.
- Personnel: All operations described must only be performed by skilled, authorized personnel.
- Installation Environment: The appliance must be installed in a hygienically clean location, avoiding places like cellars and storerooms, which can promote bacterial growth.
- Cleaning Kit: A specific cleaning and sanitizing kit is available from the dealer.
- Chemicals:
- Cleaning: A 25% solution of water and white vinegar is used for initial cleaning of the basin. Ordinary washing-up liquid is used for cleaning various removable parts and internal surfaces.
- Sanitizing: A 200 mg/l solution of sodium hypochlorite and water (or 1/2 ounce of normal bleach to 1 gallon of water) or solutions commonly used for disinfecting baby bottles are recommended. The sanitizing product must be authorized by the country's Ministry of Health, suitable for food machines, and not harmful to the appliance's materials. The recommended temperature for the sanitizing solution is 25°C.
- Prohibited Substances: Corrosive substances for limestone removal are strictly prohibited as they invalidate the guarantee and can damage the appliance.
- Safety Precautions:
- Gloves: Gloves suitable for protecting against cuts must be worn when handling sheet metal parts. Gloves suitable for protecting skin against cleaning substances must be worn.
- Goggles: Suitable goggles must be worn to protect eyes from splashes.
- Water Spillage: Care must be taken not to spill water or solutions on internal components, wiring, or the power cable.
- Disassembly and Reassembly: The manual provides detailed steps for disassembling and reassembling various parts for thorough cleaning:
- Removing the flag support assembly, ice-cube slide, and overflow pipe.
- Removing the top of the appliance (by lifting the rear part and releasing from front hooks, after removing a screw from the rear panel).
- Removing the rear panel (by extracting fixing screws).
- Removing the evaporator cover panel.
- Opening the pump basin (by removing screws with a Phillips screwdriver).
- Releasing pump wiring and raising the pump assembly.
- Disconnecting the sprayer bank feed pipe.
- Removing the sprayer bank and its side caps, and pump filters.
- Cleaning Steps:
- Initial cleaning of the basin with a water/vinegar solution, followed by operating the appliance for short cycles.
- Cleaning the evaporator, bin, evaporator cover panel, and door with water and vinegar.
- Removing sediment from the evaporator and cover panel with a brush and non-abrasive sponge, directing sediment into the basin.
- Cleaning various removable parts (flag support, ice-cube slide, overflow pipe, sprayer bank, sprayer bank feed pipe, pump filters) with washing-up liquid.
- Cleaning internal surfaces (evaporator cover panel, inner basin, pump basin, immersed pump parts, pump basin lid, bin, door) with washing-up liquid.
- Thoroughly rinsing all cleaned parts with cold water.
- Rinsing the pump basin with pressurized cold water.
- Sanitizing Steps:
- Filling the basin with sanitizing solution.
- Refitting the ice-cube slide and flag support assembly.
- Operating the ice maker for five one-minute periods with five-minute breaks.
- Immersing removed parts (flag support, ice-cube slide, overflow pipe, sprayer bank, sprayer bank feed pipe, pump filters, evaporator cover panel) in sanitizing solution for 30 minutes.
- Wiping container walls, door, pump basin walls, immersed pump parts, and pump basin lid with sanitizing solution using a sponge and brush.
- Thoroughly rinsing all parts with cold water after sanitizing.
- Post-Maintenance:
- All ice produced during the first five cycles after cleaning and sanitizing operations must be discarded.
- Ensuring all cables and electrical wiring are perfectly dry before reconnecting to the electricity supply.
- The manual also covers the removal and refitting of the appliance from its flush-mounting installation for maintenance.
The manual emphasizes that the figures are of a general nature and details may differ by model. The manufacturer disclaims liability for inaccuracies and reserves the right to make modifications to the product without impairing its essential features.
