Yes, the MIDEA MRF18B4AST refrigerator comes set up for ice maker installation and is compatible with the Midea IM1900MD ice maker. Please refer to the individual ice maker installation instruction manual. Key points to remember are:

• WARNING: Connect to potable water supply only.

• Minimum/Maximum inlet water pressure: 138/827 kPa (20/120 psig).

To ensure proper performance and prevent degradation of freezing capability and increased electricity costs, allow over 100 mm (approx. 4 inches) of clearance from each adjacent wall when installing the appliance. This clearance is needed on the sides and top for proper air circulation.

The following table outlines the dimensions in mm for the MIDEA MRF18B4AST:

To avoid vibration, the MIDEA MRF18B4AST must be leveled. If required, adjust the leveling screws to compensate for an uneven floor. The front should be slightly higher than the rear to aid in door closing.

You can turn the leveling screws by tipping the cabinet slightly. Turn the leveling screws counterclockwise to raise the unit, and clockwise to lower it.

If the refrigerator doors are uneven, you can adjust them using the provided fastener-rings and a pair of pliers.

1. Raise the lower door up to the level of the higher door.

2. Insert the supplied fastener-ring by using pliers in the gap between the hinge-grommet and the lower hinge. The number of fastener-rings you will need to insert depends on the size of the gap.

Follow these steps to safely move your MIDEA MRF18B4AST refrigerator:

1. Remove all food from inside the appliance.

2. Pull the power plug out, insert and fix it into the power plug hook at the rear or on top of the appliance.

3. Tape parts such as shelves and the door handle to prevent them from falling off while moving.

4. Move the appliance carefully with more than two people. When transporting it over a long distance, keep the appliance upright.

5. After installing the appliance in its new location, connect the power plug into a socket to switch it on.

Any replacement or maintenance of the LED lamps in the MIDEA MRF18B4AST is intended to be made by the manufacturer, its service agent, or a similar qualified person.

After connecting the power supply cord to the outlet, wait 2 or 3 hours before you put food into the appliance. If you add food before the appliance has cooled completely, your food may spoil.

• Do not place the appliance near heat sources like cookers or radiators. High ambient temperatures cause the compressor to run more frequently.

• Ensure sufficient ventilation at the base and on all sides of the appliance. Never cover ventilation openings.

• The arrangement of drawers and shelves as shown in the manual offers the most efficient use of energy.

• To obtain larger storage space, middle drawers can be removed, but all drawers and shelves should remain to keep the temperature stable.

• An evenly filled refrigerator/freezer contributes to optimal energy use. Avoid empty or half-empty compartments.

• Allow warm food to cool before placing it in the refrigerator/freezer.

• Allow frozen food to defrost in the refrigerator. The cold from the frozen food reduces energy consumption in the refrigerator compartment.

• Open the door only as briefly as necessary to minimize cold loss.

• Ensure the door seals are intact so that the doors close properly.

The control panel has the following keys:

• A – Alarm/power off/power on button: Silences alarms and turns the unit on/off (standby).

• B – Freezer button: Adjusts the freezer temperature setting.

• C – Fridge button: Adjusts the refrigerator temperature setting.

When first powered on, the refrigerator and freezer are set to a mid-range temperature. Under normal circumstances, the display shows the current set gear. If a fault occurs, it will display a fault code.

Press the “FRIDGE” key to adjust the refrigerator temperature. Each press changes the setting. The available settings cycle in the following order: 8°C -> 4°C -> 2°C.

Press the “FREEZER” key to adjust the freezer temperature. Each press changes the setting. The available settings cycle in the following order: -16°C -> -19°C -> -23°C.

• Fault Alarm: If a fault alarm occurs, press the “ALARM OFF” key to cancel the sound.

• Open Door Alarm: If a refrigerator or freezer door is open for 120 seconds, a buzzer will alarm. Close the door or press the “ALARM OFF” key to cancel the buzzer.

Press and hold the “ALARM OFF” key for 3 seconds to enter standby mode. In this mode, cooling stops, the light will not turn on, and the display is off. To return to normal control, press and hold the “ALARM OFF” key for another 3 seconds.

If the refrigerator detects a fault, it will display a corresponding code. Even with a fault, the refrigerator may still have some cooling function, but you should contact a maintenance specialist. The fault codes are indicated by flashing LEDs:

• The freezer is for storing already frozen food, long-term storage, and making ice.

• Do not put fresh and frozen food next to each other, as the frozen food may thaw.

• When freezing fresh food like meat or fish, cut it into portions for single use.

• Follow storage instructions on food packaging. If none are provided, do not store for more than three months.

• Ensure frozen food packaging is not damaged when purchasing.

• Keep food in suitable packages to retain quality and return it to the freezer as soon as possible after shopping.

• The storage period depends on room temperature, thermostat setting, door opening frequency, and food type. Always follow instructions on the packaging.

• To reduce moisture and ice build-up, never put liquids in unsealed containers.

• Cool warm foods to room temperature before placing them in the refrigerator.

• Ensure food does not touch the back wall to prevent freezing.

• Do not keep the door open unnecessarily.

• Meat and clean fish can be stored in a package or plastic foil for 1-2 days.

• Fruits and vegetables can be placed in their designated compartment without packaging.

The optimal temperature setting for food storage is:

• Fridge: 4 °C

• Freezer: -19°C

Note: This is based on an ambient temperature of 25 °C.

Yes, the MIDEA MRF18B4AST refrigerator is made based on the air-cooling principle and has an automatic defrosting function. Frost formed due to a change of season or temperature can also be manually removed by disconnecting the appliance from the power supply and wiping it with a dry towel.

To remove the door tray for cleaning, use both hands to squeeze the tray and push it upward, then you can take it out. After washing the tray, you can adjust its installing height according to your requirement.

To dismantle the cantilever shelf, first lift the shelf up, and then pull it outward. This is necessary because the shelf and the box gall have an innermost stop.

Cleaning the Box gall bottom roller groove:

1. First, pull out the fruit and vegetable box. Since it has a stop, you need to lift it upward before it can be fully removed.

2. The roller seat is stuck in the box tank groove. Press the arrow in the direction of the image in the manual to remove the roller seat, then clean the box tank groove as needed.

Cleaning of freezer drawers:

• Upper freezer drawer: Open the freezing chamber door to the maximum stroke, lift the tail of the upper drawer, and take it out.

• Lower freezer drawer: Open the freezing chamber door to the maximum stroke, lift the end of the lower freezer drawer, and lift it up. It is not recommended to remove the lower freezer drawer if not necessary.

If your MIDEA MRF18B4AST fails to operate, check the following:

• Check whether the appliance is connected to power and whether the plug is in well contact.

• Check whether the voltage is too low.

• Check whether there is a power failure or if partial circuits have tripped.

If there is an odor inside your MIDEA MRF18B4AST, please check the following:

• Ensure that odorous foods are tightly wrapped.

• Check if there is any rotten food inside.

• Clean the inside of the refrigerator.

Long operation of the compressor can be normal under certain conditions:

• It is normal for the refrigerator to run for longer periods in the summer when the ambient temperature is high.

• It is not advisable to have too much food in the appliance at the same time, especially in high ambient temperatures.

• Food should be cool before being put into the appliance.

• The doors may be being opened too frequently.

If the light fails to get lit, check the following:

• Check whether the refrigerator is connected to a power supply.

• Check whether the illuminating light is damaged. If it is, have the light replaced by a specialist.

If the door cannot be properly closed, consider these possible reasons:

• The door is stuck by food packages because too much food is placed inside.

• The refrigerator is tilted and needs to be leveled.

If you hear loud noises from your MIDEA MRF18B4AST, check the following:

• Check whether the floor is level and if the refrigerator is placed stably.

• Check whether accessories like shelves and drawers are placed in their proper locations.

If the door seal fails to be tight, try the following:

• Remove any foreign matters on the door seal.

• Heat the door seal and then cool it for restoration. You can do this by blowing it with an electrical drier or using a hot towel for heating.

Water pan overflow can be caused by:

• Too much food in the chamber or food that contains too much water, resulting in heavy defrosting.

• The doors are not closed properly, resulting in frosting due to the entry of air and increased water from defrosting.

The housing of the MIDEA MRF18B4AST can become hot due to the heat dissipation of the built-in condenser. This is normal, especially when the ambient temperature is high, there is too much food stored, or the compressor is running frequently. Ensure there is sound ventilation to facilitate heat dissipation.

Condensation on the exterior surface and door seals of the refrigerator is normal when the ambient humidity is too high. Simply wipe the condensate with a clean towel.

Certain noises are normal during the operation of the MIDEA MRF18B4AST:

• Buzz: The compressor may produce buzzes during operation, which are particularly loud upon start or stop. This is normal.

• Creak: Refrigerant flowing inside the appliance may produce a creaking sound, which is also normal.
