Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. The following precautions must be followed:

Work Procedure: Work shall be undertaken under a controlled procedure to minimize the risk of a flammable gas or vapor being present while the work is being performed.

General Work Area: All maintenance staff and others working in the local area shall be instructed on the nature of the work. Avoid working in confined spaces. The area around the workspace shall be sectioned off and made safe by controlling flammable material.

Checking for Refrigerant: Check the area with an appropriate refrigerant detector before and during work. Ensure the leak detection equipment is suitable for flammable refrigerants (non-sparking, adequately sealed, or intrinsically safe).

Fire Extinguisher: Have a dry powder or CO2 fire extinguisher available. If any hot work is to be conducted, appropriate fire extinguishing equipment must be on hand.

No Ignition Sources: No person carrying out work on the refrigeration system shall use any ignition sources in a manner that may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site.

Ventilated Area: Ensure the area is in the open or adequately ventilated before breaking into the system. Ventilation should continue during the work period.

The construction area for installation, operation, and storage of the TCL TCD140D1HWH-DV must be larger than the minimum construction area. This is determined by the total refrigerant charging quantity for the entire system (ex-factory quantity + additional charging quantity). Refer to the following table for the minimum required area based on the total R32 refrigerant weight.

For Ceiling Type Units (like the TCL TCD140D1HWH-DV):

INDOOR UNIT Location:

1. A place with sufficient space for repair in a hung ceiling that can bear the weight of the machine.

2. A place where the air inlet and outlet are not hindered and are without influence from outdoor air.

3. A place without heat sources like smoke, fire, or toxic pollution.

4. A place where airflow can be transmitted everywhere in the room.

5. A place convenient for installation.

OUTDOOR UNIT Location:

1. A place with sufficient space for installation and repair.

2. A place where the air inlet and outlet are not hindered, without strong air flowing.

3. A dry and ventilated place.

4. A place where the overhanging structure is level and can bear the weight of the outdoor unit, without much noise.

5. A place where neighbors are not annoyed by noise and exhausted air.

6. A place without leakage of flammable gas.

7. A place convenient for installation.

Caution: Avoid locations with flammable gas leakage, salty air (near the coast), caustic gas, locations that cannot bear the unit’s weight, kitchens full of oil gas, strong electromagnetic waves, or places with acid/alkaline liquid evaporating.

Check that the following accessories are included with your unit. Note that accessories may vary slightly by specific model within the series.

After completing the installation, perform the following checks to ensure proper and safe operation.

Also, at completion, you should show the customer how to operate the system, explain safety considerations, and hand over the operation manual.

Refrigerant piping must be done by a qualified person. Where additional refrigerant is required, use only R32.

1. Fully insulate the liquid and gas piping separately to prevent water leaks. In heating mode, the gas piping can reach 120°C, so use insulation with a suitable temperature rating.

2. Use a spanner and a torque wrench together when connecting or disconnecting pipes.

3. Use a flaring block suitable for R32 tube.

4. When connecting the flare nut, coat only the flare’s inner surface with ether or ester oil. Initially tighten by hand for 3 to 4 turns before tightening firmly with the torque wrench.

5. Use the flare nuts included with the indoor unit.

6. Refer to the table for proper tightening torque and flare dimensions. Over-tightening can cause leaks.

In an emergency without a torque wrench: Tighten with a spanner until the torque suddenly increases. From that point, further tighten the nut using the angle shown in the table below. After the work is finished, check for gas leaks.

Improperly installed drain piping may result in water leaks and damage to property. After piping work, check that drainage flows smoothly by gradually pouring approximately 1 litre of water into the drain tray.

For units with water pumps (Standard for this series):

• Use the pump for drainage via the “Pump Drain Outlet”. The “Tray Drain Outlet” needs to be blocked with the “Drain Plug”.

• The drain pipe outlet can be raised up to 600mm above the ceiling.

• Keep the horizontal pipe length short (100mm or less) before the vertical rise to prevent backflow.

General Drain Piping Installation:

• Keep the drain pipe short and sloping downward at a gradient of at least 1/100 to prevent air pockets.

• Secure the pipe every 1 to 1.5m to prevent sagging.

• Use the provided drain hose and clamp, and tighten the clamp firmly.

• Insulate the drain hose and any metal clamps inside the building to prevent condensation.

• As a safety measure, use a separate safety drain tray (field supplied).

• Do not connect the drain piping directly to sewage pipes to prevent odors and corrosion.

All wiring must be performed by an authorized electrician. Please refer to the specified parameters for the indoor and outdoor units.

The TCL TCD140D1HWH-DV models are pre-charged with refrigerant for 20 meters of connecting piping.

• If pipeline length exceeds 20 meters: Additional refrigerant is required. The formula is:
Additional charge (kg) = {Main length (m) – 20(m)} × 0.03 (kg/m).

• If pipeline length is between 10m and 20m: Refrigerant must be reduced for optimal performance. The formula is:
Amount reduced (kg) = {20(m) – main length (m)} × 0.03 (kg/m).

• If pipeline length is between 5m and 10m: Refrigerant must be reduced for optimal performance. The formula is:
Amount reduced (kg) = {20(m) – main length (m)} × 0.03 (kg/m).

• If pipeline length is shorter than 5 meters: The refrigerant shall be at the rated charge indicated on the nameplate for 5 meters of refrigerant pipeline.

The additional charge per meter of pipe for the TCD140/160 model is 30g/m.

The limits for the refrigerant connection pipe are as follows:

When the height drop between the indoor and outdoor units is longer than 10m, an oil return bend should be added every 6m.
