This document is a cleaning and sanitizing manual for an Automatic Modular Ice-Cube Maker with Vertical Evaporator System. It is specifically intended for authorized maintenance personnel and outlines the procedures for maintaining the hygiene and functionality of the ice maker.
Function Description
The device is an automatic modular ice-cube maker designed to produce ice cubes using a vertical evaporator system. It is modular, suggesting that it can be integrated into various setups or configurations. The primary function is to generate ice cubes, and the manual focuses on ensuring this process is carried out hygienically and efficiently.
Important Technical Specifications
The manual provides a table (Fig. 2) that correlates daily ice production with specific quantities of cleaning solution and water/vinegar solution required for maintenance. While not explicitly stating the maximum daily production, the table lists values up to 750 kg, indicating that models with this capacity exist. The cleaning and sanitizing solutions are critical:
- Cleaning Solution: A 25% solution of water and white vinegar. The required amount varies based on daily output:
- 140 kg/day: 3 units of solution
- 200 kg/day: 5 units of solution
- 400 kg/day: 5 units of solution
- 750 kg/day: 8 units of solution
- Sanitizing Solution: A 200 mg/l solution of sodium hypochlorite and water (equivalent to ½ ounce of normal bleach to 1 gallon of water), or a solution commonly used to disinfect babies' feeding bottles, provided it is authorized by the country's Ministry of Health, suitable for food-making machinery, and not harmful to the appliance's materials. The recommended temperature for the sanitizing solution is 25°C. The amount of sanitizing solution needed also depends on daily output, following the same quantities as the cleaning solution.
The manual also mentions specific components like the evaporator, overflow pipe, ice-cube chute, sprayer bank, sprayer bank feed pipes, evaporator cover panel, basin, and tilting panel, which are integral to the ice-making and cleaning processes. The design includes removable panels (front, right-hand side, top, evaporator cover) for access during maintenance.
Usage Features
The manual primarily focuses on maintenance rather than daily operational usage. However, it implicitly suggests that the ice maker operates automatically to produce ice cubes. The "washing pushbutton" (1 in Fig. 3) is a key operational feature for initiating the cleaning cycle. The device is designed to be connected to a mains power supply and has a luminous switch for turning it on and off.
For models with a daily production of 750 kg, the manual describes specific panel removal procedures (front right-hand, front left-hand, rear left-hand panels, and left-hand part of the top) to access the washing pushbutton and evaporators, indicating a potentially larger or more complex design for higher capacity units.
Maintenance Features
The manual details a comprehensive cleaning and sanitizing regimen, emphasizing the importance of regular maintenance (at least once a month) to ensure correct operation and hygiene. The frequency of these operations can be influenced by environmental conditions, water quality, ice production volume, and periods of non-use.
Key Maintenance Steps (Cleaning):
- Preparation: Switch off, disconnect from power, remove the front panel (Fig. 1).
- Draining and Filling: Remove the overflow pipe (Fig. 2) to drain water, then reposition it and fill the basin with the water/vinegar cleaning solution (25% concentration, amounts specified in Fig. 2 table).
- Initiating Cleaning Cycle: Reposition the front panel, remove the right-hand side panel (Fig. 3), press the washing pushbutton (1 in Fig. 3), and reposition the right-hand side panel.
- Automated Cleaning: Connect to power, switch on, and operate for at least 20 minutes.
- Manual Cleaning: Switch off, disconnect from power, remove front, top, and evaporator cover panels (Fig. 1, Fig. 4). Clean both sides of the evaporator with the water/vinegar solution using stiff and soft brushes (Fig. 5). Care must be taken not to bend coils, detach water supply pipes, or remove the evaporator thermostat.
- Component Cleaning: Remove and clean the overflow pipe (Fig. 2), ice-cube chute (2), sprayer bank (3) (after removing side caps 4), and sprayer bank feed pipes (5) with ordinary washing-up liquid (Fig. 6). Also clean the evaporator cover panel, basin, and tilting panel (7 in Fig. 6) with washing-up liquid and a non-abrasive sponge.
- Rinsing and Refitting: Rinse all cleaned components and refit them (Fig. 6).
Key Maintenance Steps (Sanitizing):
- Preparation: Fill the basin with the sanitizing solution (200 mg/l sodium hypochlorite or approved alternative, at 25°C, amounts specified in Fig. 2 table). Reposition the front panel.
- Automated Sanitizing: Ensure all cables are dry, connect to power, switch on, and operate for at least 20 minutes.
- Manual Sanitizing: Switch off, disconnect from power, remove front, top, and evaporator cover panels (Fig. 1, Fig. 4).
- Component Immersion: Remove and immerse the overflow pipe (Fig. 2), ice-cube chute (2), sprayer bank (3) (with side caps 4 removed), sprayer bank feed pipes (5), and evaporator cover panel (Fig. 4) in the sanitizing solution for 30 minutes (Fig. 6).
- Evaporator and Tilting Panel Sanitizing: Pour sanitizing solution onto both sides of the evaporator (Fig. 5) and the tilting panel (7 in Fig. 6), distributing with stiff and soft brushes.
- Thorough Rinsing: Thoroughly rinse the evaporator, tilting panel, and inner basin with plenty of cold water.
- Final Rinsing and Refitting: Thoroughly rinse the ice-cube chute, evaporator cover panel, sprayer bank (with side caps), overflow pipe, and sprayer bank feed pipes under running water. Refit all previously removed parts, securing panels with screws.
Important Safety and Operational Notes:
- Maintenance operations must only be performed by skilled, authorized personnel.
- The appliance must be installed in a hygienically clean location.
- A specific cleaning and sanitizing kit is available from the dealer.
- Corrosive substances for limestone removal are forbidden as they invalidate the guarantee and can damage components.
- Protective gear (gloves for cuts, gloves for skin protection, goggles for eye protection) must be worn.
- Care must be taken not to spill water or solutions on wiring or the power cable.
- After cleaning and sanitizing, the first five cycles of ice produced must be discarded.
- The ice bin must also be cleaned and sanitized.
The manual emphasizes that the figures are general and details may vary by model, and the manufacturer disclaims liability for inaccuracies or transcription errors, reserving the right to make product modifications in the user's interest without impairing essential features.
