This manual provides instructions for the Brass Monkey 65L 12V/24V Fridge and Freezer (Model GH-1676). Before first use, ensure the unit is unpacked and stands upright on a level surface for at least 6 hours. The fridge is designed for 12V/24V DC power. You can control the temperature and settings via the control panel or the dedicated smartphone app.

Product description
The unit features a high-efficiency DC compressor, intelligent voltage detection to protect vehicle batteries, and an LCD display. It includes a removable freezer zone and a reversible door for flexible installation.
Installation
When installing in a cabinet, ensure there is at least 75mm of ventilation space on each side, at the rear, and at the top. The unit must be placed on a flat, level surface. Connect the fridge directly to the vehicle's 12V/24V DC power supply. Use the appropriate wire gauge based on the distance between the fridge and the battery: 14AWG for up to 6m, 12AWG for up to 11m, and 10AWG for up to 17m.


Operation
To turn the fridge on, connect the power and press the power button. Press the set button to toggle between the freezer zone (FR) and refrigerator zone (RE) temperature settings. Use the plus (+) or minus (-) buttons to adjust the temperature. To set the battery protection mode, hold the set button for 3 seconds; you can cycle through L (Low), M (Medium), and H (High) protection levels. H is recommended for vehicle starter batteries.
Advanced features
You can remove the freezer zone lid and divider to increase the refrigerator section space. The door opening direction can be reversed by unscrewing the hinges and moving the door latch and decorative sheets to the opposite side. The fridge can be monitored and controlled via the Brass Monkey app, which can be downloaded by scanning the QR code in the manual.

Cleaning and maintenance
Before cleaning, disconnect the power. Clean the exterior with warm water and a soft cloth. For the interior, remove racks and containers and clean with warm water mixed with a little bicarbonate of soda or vinegar. The condenser should be cleaned at least once a year using a vacuum or dry brush. If the fridge will not be used for a long period, clean it, dry it thoroughly, and store it with the door ajar to prevent mould.
Troubleshooting
If the fridge is not working, check the power supply, fuse, and connections. If error codes appear: F1 indicates low voltage (adjust battery protection); F2 indicates fan overload (restart after 30 mins); F3 indicates compressor overload (restart after 30 mins); F5 indicates high temperature (move to a ventilated area); F7/FS indicates a sensor error.
