the accumulative charge quantity of modules upon delivery is used) + Onsite charge quantity = Total
refrigerant charge quantity in the system (kg)
(2) Calculate the volume of maximum air conditioning space (m³).
Volume of air conditioning space (m³) = Length x Width x Height
Note: The length, width and height here refer to the effective length, width and height of the indoor
space.
(3) Calculate the maximum refrigerant concentration of the refrigeration system.
Note: If the maximum supported refrigerant concentration is not available in relevant local standard,
use 0.3kg /m³ (0.66lbs/m³) as the maximum supported refrigerant concentration.
2) If the maximum refrigerant concentration exceeds the allowed threshold, the refrigeration system
must be redesigned. In this case, separate the refrigeration system into multiple small-capacity
refrigeration systems, or add corresponding ventilation measures or alarming display.
(1) Flow direction of refrigerant leakage.
(2) Room for refrigerant leakage. Since the concentration of refrigerant is greater than that of air,
pay attention to the spaces where the refrigerant may residue, for example, the basement.

4.6 Electric Wiring

4.6.1 Wiring precautions
(1) Wiring should conform to national rules. All the parts, materials, electric work should be in accordance with local
codes.
(2) Rated voltage and exclusive power supply should be used.
(3) Power cord should be fixed soundly and reliable. Never forcibly pull the power cord.
(4) Wire size of power cord should be large enough. The damaged power cord and connecting wire should be replaced
by exclusive cable.
(5) All the electrical work should be performed by professional personnel as per local law, regulation and this manual.
