• **Power On Check:** The installed air conditioner should be powered on to check for any electricity leakage.

• **Drainage Issues:** If the drainage hole is blocked, the filter is dirty, or airflow speed changes, it may lead to dripping or sputtering of water.

• **Heating Apparatus:** Do not place any heating apparatus under the indoor unit, as it might distort the unit.

• **Flammable Items:** Do not place flammable items where air from the unit can come in direct contact with them.

• **Plants and Animals:** Do not place plants and animals in the direct path of the wind from the air conditioner, as it could harm them.

• **Preservation:** The unit cannot be used for the preservation of food, living creatures, precision instruments, artworks, etc.

• **Fuse:** Use a fuse with the proper capacity.

• **Wet Hands:** To avoid electric shock, do not touch switches with wet hands.

• **Sunlight/Outdoor Air:** Close windows to keep outdoor air from entering. Use curtains or window shutters to avoid sunlight.

• **Cleaning:** Stop the unit and switch off the manual power when cleaning. Cleaning the unit with water may cause an electric shock.

• **Flammable Sprays:** Do not put or direct flammable sprays close to or at the air conditioner, as this may cause a fire.

The air cleaner should only be cleaned when the unit is switched off and disconnected from the power supply to avoid electric shock and injury.

1. **Cleaning:** Clean the air cleaner with a vacuum cleaner or water to remove dust.

2. **Heavy Dust:** If there is too much dust, use a fan or directly spray a special cookware detergent on the air inlet grid, and then clean it with water after 10 minutes.

(A) Remove dust with a vacuum cleaner.

(B) For excessive dust, use a soft-hair brush and a mild detergent to clean.

(C) Allow the filter to dry fully before reinstalling.

Attention:

• Do not clean with hot water over 50°C to avoid fading or distortion.

• Do not dry the filter on a fire, as this might cause the cleaner to catch fire.

To clean the air outlet port and shell, first ensure the CARRIER 40VD012H-7S-QEE is switched off and disconnected from the power supply.

• Wipe them with a soft, dry cloth.

• If dust cannot be removed, water or a neutral dry cleanser is recommended.

Attention:

• Do not use gasoline, benzene, diluents, polishing powder, or liquid insecticide to clean them.

• Do not clean them with hot water above 50°C to avoid fading or distortion.

If you are experiencing issues with your CARRIER 40VD012H-7S-QEE, please check the following before calling for service:

If the unit fails to work:

• Check if there is a power failure.

• Check if the manual power switch is turned off.

• Check if the supply fuse and breaker are disconnected.

• Check if the protective unit is working.

• Check if refrigerating and heating functions are selected simultaneously with the awaiting indication on the line control.

For bad cooling and heating effects:

• Check if the air intake and air outlet ports of the outdoor units are blocked.

• Check if the door and windows are open.

• Check if the filtering screen of the air cleaner is blocked with sludge or dust.

• Check if the wind quantity setting is at low wind.

• Check if the operation setting is in the Fan Operation state.

For automatic start or stop:

• Check if the unit is in the state of Timer-ON and Timer-OFF.

The following are normal occurrences and not signs of a malfunction with your CARRIER 40VD012H-7S-QEE:

• **Water flow sound:** Can be heard when starting, during, or after stopping operation. It is the sound of flowing refrigerant or draining condensed water and may become louder for 2-3 minutes during operation.

• **Cracking sound:** A cracking sound may be heard during operation, caused by temperature changes or slight dilation of the heat exchanger.

• **Bad smell in outlet air:** This is caused by smells from walls, carpet, furniture, clothing, smoke, and cosmetics that attach to the conditioner.

• **Flashing operating indicator:** When switching the unit on again after a power failure, the operating indicator will flash after turning on the manual power switch.

• **Awaiting indication:** This appears when the unit fails to perform a refrigerating operation while other indoor units are heating, or if the operation mode is opposite to the setting.

• **Sound when indoor unit is shut down; or white steam/cold air:** To prevent blockage, refrigerant flows for a short time, making a flowing sound. White steam may occur during heating, and cold air may appear during refrigerating operation.

• **Clicking sound when switching on:** This sound occurs due to the resetting of the expansion valve when the air conditioner is powered on.

Under the following circumstances, immediately stop the operation, disconnect the manual supply switch, and contact after-service personnel:

• When buttons are inflexibly actuated.

• When the fuse and the breaker have been burnt.

• When there are foreign objects and water in the refrigerant.

• When other abnormal conditions occur.

Ask the installation personnel to make a test run. Follow the procedures to check if the temperature regulator works properly.
