This document is a user manual for the Costway Car Fridge, model EP24449US. It provides comprehensive information on the product's features, usage, maintenance, and technical specifications.

Function Description

The Costway Car Fridge is a versatile cooling appliance designed for both car and home use. It utilizes a high-efficiency and energy-saving DC compressor with a conversion module, ensuring reliable performance and fast refrigeration for both cooling and deep freezing. The temperature control range is from -26°C to 10°C, allowing for various refrigeration needs. The refrigerator can achieve temperatures as low as -26°C when the ambient temperature is below 25°C, and -22°C when the ambient temperature is above 25°C. It features a non-fluorine environmental insulation layer for good insulation performance and low energy consumption. The outer box is constructed from high-quality engineering plastics, giving it a durable and aesthetically pleasing appearance. The appliance supports dual power input, operating on 12V/24V DC car power or 220V AC home power via a power adapter.

The control panel includes buttons for "Increase," "Decrease," "Set," and "Power ON/OFF," along with an LCD display. To power on or off, the "Power ON/OFF" button must be long-pressed for 3 seconds. The compressor has a 3-minute delay protection, meaning it will start working 3 minutes after the refrigerator is turned on. Temperature adjustment is done using the "Increase" or "Decrease" buttons, and the setting is memorized. A short press of the "Set" button allows cycling through temperature units (°C, °F) and compressor speed settings (ECO for energy-saving mode at 3000R/min, MAX for fast cooling at 2000R/min). The refrigerator also features battery voltage protection with three levels: Low (V-), Mid (V=), and High (V). These settings determine the cut-out and cut-in voltages for 12V and 24V systems to prevent over-discharge of the battery. The refrigerator has a power memory function, retaining the last temperature setting after a restart.

Usage Features

Placement: The refrigerator should be placed on a flat, steady, and stable surface. When used in a car, it should be securely fixed with pull belts.
Ventilation: Good ventilation is crucial for heat dissipation. A minimum space of 200mm is required at the back and 100mm on the sides.
Heat Sources: Avoid placing the refrigerator near heat sources or in direct sunlight.
Moisture: Protect the refrigerator from excessive moisture to prevent rusting and insulation issues. Do not rinse with water.
Power Supply: Ensure the product is connected to the correct voltage. When used in cars or ships, the power supply must have fuses and ground protection devices. Disconnect from power supply when charging car batteries.
Safety: Do not touch damaged power lines or the power plug with wet hands or feet. Avoid using electrical products inside the refrigerator.
Loading: Do not overfill the refrigerator to ensure proper cold air circulation. Avoid placing too much hot food inside.
Troubleshooting: The manual provides a simple fault analysis section for common issues like the refrigerator not working, abnormal noise, condensation, or poor cooling. Error codes (ER0, ER1, ER2, ER3, ER4, ER5, ER9) are displayed for specific malfunctions such as temperature sensor short circuit, input under-voltage, DC fan over-current, compressor abnormal start, rotational speed abnormal, module temperature abnormal, and temperature sensor open circuit.

Maintenance Features

Cleaning Method: Clean the appliance inside and out with a clean damp cloth every two weeks. For dirt, use a neutral detergent and wipe dry. Excess water can be drained through the drainage pipe at the bottom of the tank.
Plastic Parts Maintenance: Clean plastic parts frequently to protect seals and avoid heavy impact. Promptly clean any oil (animal or vegetable) attached to plastic parts to prevent deterioration, cracking, and odor.
Precautions: Do not wash the refrigerator directly with water to prevent electrical insulation decrease and sheet metal rust. Avoid using alkaline detergents, soap, grinding powder, hot water, brushes, Toluene water, gasoline, or alcohol for cleaning, as these can damage the coated surface and plastic parts.
