CARRIER 40VD024H-7S-QEE (01) PDF Document

Before installing your CARRIER 40VD024H-7S-QEE, it is crucial to read and follow all safety considerations. Improper installation can lead to severe accidents, including serious injury or death.

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

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

• Be sure to install the air conditioner in a place that can bear its weight. It should not be installed on grids such as metal burglar-proof nets. Insufficient support strength could result in the dislodgement of the machine, which may lead to physical injuries.

• The installation must be strong enough to withstand typhoons and earthquakes. Nonconformance to installation requirements can lead to accidents.

• Wiring should be selected in accordance with applicable codes and standards. Ensure terminal connections are made secure. Improper connections could lead to shock or fire.

• Maintain correct shapes of wiring. Wirings should be reliably connected to keep the cover and the plate of the electrical cabinet from clipping the wiring. Improper installation might cause heating or fire accidents.

• While placing or reinstalling the air conditioner, do not let air enter the refrigeration cycle system. Air in the system could lead to cracking or result in physical injuries because of the abnormally high pressure of the refrigeration cycle system.

• During installation, use the accompanying spare parts or specific parts to avoid water leakage, electric shocks, fire accidents, or refrigerant leakage.

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

• Do not install the air conditioner where there are chances of flammable gas leakage, which could result in fire accidents.

• The drainpipe should be properly mounted in accordance with the instructions in this manual to ensure smooth drainage and be properly insulated to avoid condensation. Improper drainpipe mounting might cause water leakage.

• The refrigerant gas pipe and liquid pipe should be properly insulated to prevent condensation. Inappropriate heat insulation might cause the dripping of condensed water, resulting in water damage.

To ensure safe operation of your CARRIER 40VD024H-7S-QEE, please adhere to the following precautions:

• The air conditioner should be effectively grounded. Electric shocks may occur if the air conditioner is ungrounded or inappropriately grounded. The earthing wire should not be connected to the gas pipe, water pipe, lightning rod, or telephone connections.

• A breaker for electricity leakage should be mounted to prevent electric shocks.

• The installed air conditioner should be powered on to check for electricity leakage.

• If the drainage hole is blocked, the filter is dirty, or there is a change in airflow speed, it may lead to dripping of condensed water.

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

• Flammable apparatuses should not be placed where the air from the air 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.

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

• Close the window to keep outdoor air from entering. Curtains or window shutters can be drawn to avoid sunlight.

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

• During operation, do not switch off the manual power switch; use the controller instead. To prevent damage, do not press the liquid crystal zone of the controller.

• Cleaning the unit with water may cause electric shock.

• Do not put or direct flammable sprays close to or at the air conditioner, which may cause a fire.

To clean the air outlet port and shell of your CARRIER 40VD024H-7S-QEE, ensure the unit is switched off and disconnected from the power supply to prevent electric shock and injury. Follow these guidelines:

• 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.

• Wipe the surfaces with a soft, dry cloth.

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

To clean the air filter of your CARRIER 40VD024H-7S-QEE, make sure the unit is switched off and disconnected from the power supply. Follow these steps:

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

2. If there is too much dust, use the 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 of over 50°C to avoid fading or distortion.

• Do not dry on the fire, as the cleaner might cause a fire.

If you are experiencing issues with your CARRIER 40VD024H-7S-QEE, please check the following common symptoms and their potential causes before calling for service.

Normal Operation Concerns

Please Recheck

Under the following circumstances, you should 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.

To test the drainage system of your CARRIER 40VD024H-7S-QEE, follow these steps:

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

2. During testing, make sure that the water flow passes through the piping correctly without any water leakage at the connections. You can provide about 1000cc of water to the equipment via the air outlet port with a feed pump to check.

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

4. Even if the unit is installed in a season when heating is needed, the testing should still be performed.

The tubing material for the CARRIER 40VD024H-7S-QEE is Phosphor–deoxy-bronze seamless pipe (TP2) for air conditioners. The specific tubing sizes vary by model:

When connecting the refrigerant tubing for your CARRIER 40VD024H-7S-QEE, it is important to use the correct mounting torque to ensure a secure connection and prevent leaks. Always use dual wrenches for connecting the indoor unit tubing. The required torque depends on the outer diameter of the tubing:

The noise level of all machines in this series is below 70 dB. The specific sound pressure levels and weights for each model are as follows:

The correct wiring specifications depend on the total current of the indoor unit(s). Please follow the table below for proper electrical installation. Note that shielded lays of all indoor and outdoor units should be connected together and grounded at one point on the outdoor unit side. The total length of the signal line should not exceed 1000m.

Signal Wiring of Wired controller

The total length of the signal line for the wired controller should not be more than 250m and must be grounded at one end.

When the CARRIER 40VD024H-7S-QEE fails to start due to room temperature, you can initiate a forced run for testing purposes. 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 into the compulsive refrigerating/heating mode.

• To quit the compulsive running, press the “ON/OFF” button again. This will stop the operation of the air conditioner.

If a fault occurs with your CARRIER 40VD024H-7S-QEE, a code will be displayed on the wired controller or indicated by the flashing of the PCB LED5 (Indoor Units) or Receiver Timer Lamp (Remote Controller). Use the following table to identify the fault.
