The MCV-2 is an electronic fan designed for use in caravans, specifically for refrigerators, to improve air circulation. This device is part of the "Energy Line" series by CBE, a company specializing in electronics for caravanning. The manual provides instructions in Italian, English, French, and German, and was published in March 2018 (cod. 000200A Rev.03).
Function Description
The MCV-2 fan is designed to be installed in the upper grille of a refrigerator to facilitate air circulation from the inside to the outside. This helps in maintaining optimal refrigerator performance by dissipating heat more efficiently. The device features a control panel with a temperature threshold regulating trimmer, an operating mode selector switch, and LED indicators for operational status.
Important Technical Specifications
- Power Supply: 12V DC (direct current).
- Current Draw: 0.16A (as indicated on the fan motors, model SP922512L C1).
- Fan Type: DC Brushless Fan Motor (Bi-Sonic Technology Corp.).
- Cable Cross-Section: Minimum 1mm² for power connections.
- Fuse Protection: The device should be connected to a fuse-protected line.
- Temperature Threshold Range: Adjustable, with preset thresholds around 28°C/35°C and 50°C.
- Control Panel Hole Diameter: A 13mm hole is required for the connector passage during installation.
- Dimensions for Disposal: Electronic products for disposal with dimensions smaller than 25 cm can be handed over free of charge to retailers with a sales area of at least 400 m².
Usage Features
The MCV-2 offers two primary operating modes:
-
Manual Mode:
- In this mode, the fan operates at its maximum speed continuously. This is useful for situations requiring immediate and strong ventilation, such as during very hot weather or after loading a large amount of warm food into the refrigerator.
-
Automatic Mode:
- This mode provides intelligent fan operation based on temperature.
- Reduced Speed Operation: The fan operates at a reduced speed when the temperature is within a user-defined threshold, typically between 28°C/35°C and approximately 50°C. This helps maintain a stable temperature without excessive noise or power consumption.
- Full Speed Operation: The fan switches to full speed operation when the temperature exceeds approximately 50°C. This ensures maximum heat dissipation when the refrigerator is working harder to cool down.
The control panel includes:
- Trimmer (1): Used to regulate the temperature threshold for automatic operation. This allows users to customize the temperature range at which the fan operates at reduced speed.
- Selector Switch (2): Toggles between MANUAL and AUTOMATIC operating modes.
- LED Indicators (3):
- Green LED: Indicates that the fan is powered (ventilator alimentato).
- Yellow LED: Indicates automatic operation at reduced speed (funzionamento automatico a bassa velocità).
- Red LED: Indicates manual operation or automatic operation at maximum speed (funzionamento manuale o automatico alla massima velocità).
Installation Instructions
- Placement: The fan should be installed in the upper grille of the refrigerator. The orientation is crucial: air circulation should occur from the inside of the refrigerator towards the outside.
- Sensor Orientation: The temperature sensor must be directed towards the inside of the refrigerator to accurately measure the internal temperature.
- Mounting: The specific mounting method may vary depending on the type of refrigerator grille. Users should choose the most convenient fixing solution.
- Control Panel Installation: The bottom of the control panel box can be used as a drilling template. A 13mm hole is required for the connector to pass through.
- Electrical Connection:
- Ensure the power supply voltage is 12V DC.
- Observe correct polarity: black wire for negative (-), red wire for positive (+).
- Use cables with an adequate cross-section (minimum 1mm²).
- Connect the device to a line protected by a fuse to prevent electrical damage.
Maintenance Features
The manual does not explicitly detail maintenance features but implies general care for electronic devices.
- WEEE Compliance: The product is marked with the WEEE symbol, indicating that it should not be disposed of with general household waste. This is to prevent environmental harm and promote sustainable reuse of materials. Users are instructed to separate the product and its accessories from other waste types and recycle them responsibly according to local regulations.
- Disposal for Domestic Users: Domestic users can hand over the appliance to be disposed of to the retailer when purchasing a new, equivalent appliance. Retailers of electronic products with a sales area of at least 400 m² must accept electronic products smaller than 25 cm for disposal free of charge, without the obligation of a new purchase.
The MCV-2 is a practical accessory for caravan refrigerators, enhancing their efficiency and contributing to better temperature management, especially in varying environmental conditions.
