The TCL TCD100D1HWH-DV is pre-charged for 20 meters of connecting piping. The refrigerant amount needs adjustment if the pipe length is different.

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

• **If pipeline is 10m to 20m:** Reduce refrigerant.
Amount of refrigerant reduced (kg) = {20(m) – main length (m)} x 0.03 (kg/m)

• **If pipeline is 5m to 10m:** Reduce refrigerant.
Amount of refrigerant reduced (kg) = {20(m) – main length (m)} × 0.03 (kg/m)

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

The additional charge per meter of pipe for R32 is 30g.
