• Did you hand the operation manual over to the customer?

All refrigerant piping work must only be carried out by a qualified person. Follow these guidelines:

• Fully insulate the liquid and gas piping separately. Do not leave any gaps, otherwise a water leak may occur. Seal any joints with glue or duct tape.

• In heating mode, the gas piping temperature can reach approximately 120°C. Use insulation with a suitable temperature rating.

• If the temperature and humidity around the piping exceed 30°C or RH80%, reinforce or use thicker pipe insulation (20mm or thicker) to prevent condensation.

• If additional refrigerant is required, use only R32. Using other refrigerants could cause malfunction, leaks, or explosion.

CAUTION:

• Avoid introducing air or other contaminants into the piping. Any contaminants remaining after installation will cause the system to malfunction.

• Carry out sufficient ventilation if refrigerant gas leaks during installation.

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

• Use only a flaring block suitable for R32 tube.

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

• Use the flare nuts included with the indoor unit.

• Refer to the table for proper tightening torque and flare dimensions.

Note: Over-tightening the flare nuts may cause them or the copper tube to fail, leading to a refrigerant leak. Be sure to insulate local piping all the way into the pipe connections inside the machine. Exposed piping may cause condensation or burns on contact.

WARNING: Install the drain pipe as shown and take measures against condensation. Improperly installed piping may result in water leaks and wet furniture and belongings.

Drain Test:

1. After piping work is finished, check that the drainage flows smoothly by pouring approximately 1 Litre of water gradually into the drain tray.

2. For units with a pump, conduct a drain test after completing electrical work.

3. During the test, ensure drain flows properly and there are no leaks from connections.

4. In a new building, conduct the test before the ceiling is furnished.

5. Conduct this test even if the unit is installed in the heating season.

Test Method (for units with a pump):

• Remove the test cover.

• Fill the water pan with 2 liters of water using a stow tube.

• Turn on the unit in COOLING mode. You will hear the drain pump work. Check if the water is discharged properly (a 1-minute lag is possible). Check for leaks from the joints.

• Turn off the air conditioner and put the cap back on.

Installation Guidelines:

• Route the pipes to ensure drainage can occur without problems.

• Use piping with the same or larger diameter than the connecting pipe (PVC pipe, nominal diameter 25mm, outside diameter 32mm).

• 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. Tighten the clamp firmly.

• Insulate the drain hose inside the building.

• As a safety measure, use a safety drain tray (field supplied) and drain it separately.

• Insulate the drain pipe using thermal insulation to prevent condensate dripping in humid conditions.

• To ensure no excessive pressure is applied to the included drain hose, do not bend or twist it during installation.

The TCL TCD160D1HWH-DV models are pre-charged with refrigerant for 20 meters of connecting piping.

1. When the length of the refrigerant pipeline exceeds 20 meters, additional refrigerant is required for reliable operation. The formula is: Additional charge (kg) = {Main length (m) – Factory charge length 20(m)} × 0.03 (kg/m)

2. When the refrigerant pipeline is longer than 10m but shorter than 20m, a reduction in refrigerant is required for optimal performance. The formula is: Amount of refrigerant reduced (kg) = {Factory charge length 20(m) – main length (m)} × 0.03 (kg/m)

3. When the refrigerant pipeline is longer than 5m but shorter than 10m, a reduction in refrigerant is required for reliable operation. The formula is: Amount of refrigerant reduced (kg) = {Factory charge length 20(m) – main length (m)} × 0.03 (kg/m)

4. When the refrigerant pipeline 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 R32 is 30g.

The maximum longest pipe (L) is 75m and the maximum height drop (H) between the indoor and outdoor unit is 30m.
