Setup
Unpacking and Initial Inspection
Carefully remove the cooler from its packaging. Inspect the unit for any signs of damage during transit. If any damage is observed, do not operate the cooler and contact customer support immediately.

Power Connection
The MCF40 cooler offers flexible power options, allowing it to be powered from a standard household AC outlet or a vehicle's DC outlet.
- AC Power (100-240V): Connect the AC power cord to the cooler's AC input port and then to a wall outlet.
- DC Power (12/24V): Connect the DC power cord to the cooler's DC input port and then to your vehicle's 12V or 24V cigarette lighter socket.

- POWER Indicator: Illuminates when the unit is powered on.
- ERROR Indicator: Illuminates if a fault occurs.
Setting the Temperature
- Turn on the cooler by pressing the ON/OFF button.
- Press the SET button once. The digital display will start flashing, indicating that you are in temperature setting mode.
- Use the UP (+) or DOWN (-) buttons to adjust the desired temperature. The MCF40 can refrigerate or freeze down to 12°F (-11°C).
- Once the desired temperature is set, wait a few seconds. The display will stop flashing and return to showing the current internal temperature, confirming the setting.
The cooler's powerful compressor technology will then work to reach and maintain the set temperature. The compressor will cycle on and off as needed, similar to a home refrigerator, to conserve energy.
Battery Protection Feature
The Mobicool MCF40 includes a battery protection system to prevent excessive discharge of your vehicle's battery when operating on DC power. This feature has multiple settings (typically High, Medium, Low) that determine the voltage cut-off point.
- With the cooler on, press and hold the SET button for approximately 3 seconds until the battery protection indicator (often a small LED or a segment on the display) starts flashing.
- Use the UP (+) or DOWN (-) buttons to cycle through the battery protection levels (e.g., H for High, M for Medium, L for Low).
- Release the SET button to confirm your selection.
Recommendation: Use the 'High' setting for vehicle batteries to ensure sufficient power for engine starting. 'Medium' or 'Low' settings can be used with auxiliary or deep-cycle batteries.
Loading the Cooler
The MCF40 has a generous 40-quart (38-liter) capacity, capable of holding up to 48 standard cans. For optimal cooling efficiency, it is best to load the cooler with pre-chilled items whenever possible. Avoid overfilling to allow for proper air circulation.

Maintenance
Cleaning the Interior
To prevent odors and maintain hygiene, clean the interior of the cooler regularly. Disconnect the power before cleaning.
- Wipe the interior surfaces with a damp cloth and a mild detergent.
- Rinse with clean water and dry thoroughly.
- Do not use abrasive cleaners, harsh chemicals, or sharp objects that could damage the interior lining.

Cleaning the Exterior
The exterior can be wiped down with a damp cloth. For stubborn dirt, use a mild soap solution. Avoid getting water into the electrical components or ventilation openings.
Ventilation Care
Periodically check the ventilation grilles for dust and debris. Use a soft brush or vacuum cleaner to gently remove any obstructions. Clear vents ensure efficient operation and prolong the life of the compressor.
Storage
When storing the cooler for an extended period, ensure it is clean and dry. It is advisable to leave the lid slightly ajar to prevent the buildup of odors and mildew.
