Setup
Unpacking
Carefully remove all packaging materials, including tape and protective films. Inspect the refrigerator for any shipping damage. Report any damage to the carrier immediately.
Placement
Position the refrigerator on a strong, level surface capable of supporting its weight (approximately 353 pounds when empty, more when loaded). Ensure there is sufficient space for air circulation around the unit. A minimum of 4 inches of clearance from walls and other objects is recommended for optimal performance and ventilation.

Electrical Connection
Before connecting the unit, ensure the power supply matches the voltage and frequency specified on the unit's data plate. The refrigerator requires a dedicated, grounded electrical circuit. Do not use adapter plugs or extension cords.
Initial Cleaning
Before first use, clean the interior and exterior of the refrigerator with a mild detergent and warm water. Rinse thoroughly and dry completely. Allow the unit to stand for at least 2 hours after moving before plugging it in to allow refrigerants to settle.
Operating Instructions
Temperature Control
The Master-Bilt MBGR26H features adjustable temperature control. Locate the thermostat control, typically inside the cabinet or on the control panel. Turn the dial or press the buttons to set the desired temperature. Allow several hours for the unit to reach the set temperature after initial startup or adjustment.
Loading Guidelines
Do not overload the shelves. Ensure proper air circulation around stored items for efficient cooling. Avoid blocking the air vents inside the cabinet. Distribute weight evenly on shelves.
Door Operation
The glass door is designed for easy access and product visibility. Ensure the door closes completely after each opening to maintain internal temperature and energy efficiency. The door gasket should form a tight seal.
Internal Lighting
The unit is equipped with internal lighting for product display. The light switch is typically located near the top of the cabinet or on the control panel. Turn off the lights when not needed to conserve energy.
Maintenance
Cleaning the Interior
Regularly clean the interior with a mild, non-abrasive cleaner and warm water. Remove shelves and clean them separately. Rinse thoroughly and dry completely before replacing items.
Cleaning the Exterior
Wipe down the exterior surfaces with a soft cloth and mild detergent. For the glass door, use a glass cleaner. Avoid abrasive cleaners or scouring pads that can scratch surfaces.
Condenser Coil Cleaning
The condenser coil, located at the bottom of the unit, should be cleaned regularly (every 1-3 months, depending on environment) to ensure efficient operation. Disconnect power before cleaning. Use a stiff brush or vacuum cleaner to remove dust and debris from the coil fins.
Door Gasket Inspection
Inspect the door gasket regularly for cracks, tears, or signs of wear. A damaged gasket can lead to air leaks and reduced cooling efficiency. Replace damaged gaskets promptly.
Defrost System
This unit features an automatic defrost system. While manual defrosting is not typically required, ensure the drain pan and drain line are clear of obstructions to allow proper water drainage during the defrost cycle.
Troubleshooting
Before calling for service, check the following common issues:
- Unit Not Running:
- Check if the power cord is securely plugged into a live outlet.
- Check the circuit breaker or fuse.
- Ensure the temperature control is set to an appropriate cooling setting.
- Insufficient Cooling:
- Verify the temperature setting.
- Check for obstructions to airflow around the unit or inside the cabinet.
- Clean the condenser coil.
- Ensure the door gasket is sealing properly.
- Avoid frequent door openings or prolonged door open times.
- Excessive Noise:
- Ensure the unit is level and stable.
- Check if any internal components (e.g., fan blades) are loose or obstructed.
- Light Not Working:
- Check the light switch.
- The bulb may need replacement (refer to service manual or contact qualified personnel).
If problems persist after performing these checks, contact qualified service personnel.
