CARRIER 40VD009H-7S-QEE (01) PDF Document

The CARRIER 40VD009H-7S-QEE system consists of the following main parts:

• Indoor unit

• Air outlet port

• Air inlet port

• Air duct

• Soft connection

For your safety, please adhere to the following warnings during the installation of your CARRIER 40VD009H-7S-QEE:

• Improper installation could result in water leakage, electric shocks, or fire. Please contact a professional installer for installation, repair, and service.

• The installation must be conducted properly according to the manual. Improper installation could lead to water leakage, electric shocks, or fire accidents.

• Ensure the air conditioner is installed in a place that can bear its weight. Do not install it on grids like metal burglar-proof nets, as insufficient support strength could result in the machine dislodging, leading to physical injuries.

• The installation must be strong enough to withstand typhoons and earthquakes. Not conforming to installation requirements can lead to accidents.

• Wiring should be selected according to applicable codes and standards. Ensure terminal connections are secure, as improper connections could lead to shock or fire.

• Correct wiring shapes should be maintained. The wirings must be reliably connected to prevent the cover and plate of the electrical cabinet from clipping the wiring, which could cause heating or fire.

• Do not let air enter the refrigeration cycle system when placing or reinstalling the unit. Air in the system could lead to cracking or physical injuries due to abnormally high pressure.

• Use the accompanying or specified spare parts during installation to prevent water leakage, electric shocks, fire, or refrigerant leakage.

• To prevent harmful gases from entering the room, do not drain water from the drainpipe into a sanitation pipe that could contain gases like sulfurated gas.

• Do not install the air conditioner where flammable gas leakage might occur, as this could result in fire.

• The drainpipe must be properly mounted and insulated according to the manual to ensure smooth drainage and prevent condensation, which can cause water leakage.

• The refrigerant gas pipe and liquid pipe must be properly insulated to prevent condensation, which can lead to water damage from dripping water.

Please observe the following cautions and notices while operating your CARRIER 40VD009H-7S-QEE:

Cautions:

• The air conditioner must be effectively grounded. Electric shocks can occur if it is ungrounded or improperly grounded. The earthing wire should not be connected to gas pipes, water pipes, lightning rods, or telephones.

• A breaker for electricity leakage should be installed to prevent accidents like electric shocks.

• After installation, the air conditioner should be powered on to check for electricity leakage.

• If the drainage hole is blocked or the filter is dirty, it may cause dripping of condensed water.

Notices during Operation:

• Do not place any heating apparatus under the indoor units, as this might distort them.

• Flammable items should not be placed where air from the conditioner can come in direct contact.

• Plants and animals should not be placed in the direct path of the wind from the air conditioner, as it could harm them.

• The air conditioner cannot be used for the preservation of food, living creatures, precision instruments, or artworks.

• Use a fuse with the proper capacity.

• During heating, the outdoor unit will perform automatic defrosting for about 2-10 minutes when frost appears. During this time, the indoor unit fan will run at a low speed or stop.

• To avoid electric shock, do not touch the switch with wet hands.

• Close windows to keep outdoor air from entering. Use curtains or shutters to avoid sunlight.

• Stop the unit and switch off the manual power when cleaning it.

• When cleaning, do not use water as it may cause an electric shock.

• Do not put or direct flammable sprays near or at the air conditioner, as this may cause a fire.

• If one indoor unit stops operating, its fan may swing for 2-8 minutes every 30-60 minutes to protect the unit while another indoor unit is operating.

• This appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities unless they are supervised or have been given instructions by a person responsible for their safety.

Before cleaning, ensure the CARRIER 40VD009H-7S-QEE is switched off and disconnected from the power supply to avoid electric shock and injury.

Cleaning the air outlet port and the shell:

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

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

• Wipe them with a soft dry cloth. If dust cannot be removed, use water or a neutral dry cleanser.

Cleaning The Filter:

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

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

3. To remove dust, you can use a vacuum cleaner.

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

5. 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 a fire.

Before consigning a repair service, please check the following common issues and normal operational occurrences:

Normal Operation Concerns:

Please Recheck:

Immediately stop the operation, disconnect the manual supply switch, and contact after-service personnel if:

• Buttons are inflexibly actuated.

• The fuse and the breaker have been burnt.

• There are foreign objects and water in the refrigerant.

• Other abnormal conditions occur.

Follow these steps to test the drainage system:

1. After testing the electrical system, test the drainage system.

2. During testing, ensure that water flows correctly through the piping without any leakage at the connections.

3. In a new house, test the drainage system before fitting the ceiling.

4. The test should be performed even if the unit is installed in a season when heating is needed.

5. Provide about 1000cc of water to the equipment via the air outlet port with a feed pump.

6. During refrigerating operation, check the drainage system.

The wiring specifications for the power line and signal line are as follows:

Signal Wiring of Wired controller:

Ask the installation personnel to perform a test run. Before the test run, perform the following checks:

Checkup of Installation:

• Check if the mains voltage is correct.

• Check for leakage at the piping joints.

• Check if the connections of mains power and indoor & outdoor units are correct.

• Check if the serial numbers of the terminals are matching.

• Check if the installation place meets the specifications.

• Check if there is too much noise.

• Check if the connecting line is fastened.

• Check if the connectors for tubing are heat insulated.

• Check if the water is draining outside properly.

• Check if the indoor units are positioned correctly.

Ways of Test Run (Forced Run):

If the machine fails to start due to room temperature, you can initiate a forced run. This function is not available with a remote control.

• Set the wired controller to refrigerating/heating mode, then press the “ON/OFF” button for 5 seconds to enter the compulsive refrigerating/heating mode. Press the “ON/OFF” button again to quit the compulsive running and stop the operation.

If a fault occurs, you can identify the issue by consulting the fault code on the line control or by observing the flashing of LED5 on the computer panel of the indoor unit. The codes are as follows:
