    Mini Amazon III Series V6R VRF 50Hz 6 Insulation 6.1 Refrigerant Piping Insulation 6.1.1 Purpose During operation, the temperature of the refrigerant piping varies. Insulation is required to ensure unit performance and compressor lifespan. During cooling, the gas pipe temperature can be very low. Insulation prevents condensation forming on the piping.
  • Page 125 Mini Amazon III Series Figure 3-6.1: Installation of joint insulation (unit: mm) 6.2 Drain Piping Insulation  Use rubber/plastic insulating tube with a B1 fire resistance rating.  The insulation should typically be in excess of 10mm thick.  For drain piping installed inside a wall, insulation is not required.

    Mini Amazon III Series V6R VRF 50Hz 7 Charging Refrigerant 7.1 Calculating Additional Refrigerant Charge The additional refrigerant charge required depends on the lengths and diameters of the outdoor and indoor liquid pipes. Table 3-7.1 shows the additional refrigerant charge required per meter of equivalent pipe length for different diameters of pipe.
