of refrigerant (kg) which is charged ex-factory (for the system consisting of multiple modules in
parallel, the accumulative charge quantity of modules ex-factory should be used).
Total amount of refrigerant (kg) in the system≤The maximum amount of refrigerant (kg) in the
system.
(3) When the total amount of refrigerant in the system is more than the maximum amount of
refrigerant, the system should be designed again. In this case, the system can also be
separated into several systems with less capacity, or adding corresponding ventilation
measures or alarming display.

Room for refrigerant leakage. Because the density of refrigerant is greater than air, pay
attention to the spaces where the refrigerant may remain, for example, the basement.
4.5 Electric Wiring
4.5.1 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 reliably. Prohibit to pull the power cord by force.
(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 according to local laws, regulation
and manuals.
(6) Connect the unit to the special earth device and make sure the unit is earthed reliably.
(7) Air switch and circuit breaker is required to be set. Air switch should have both magnetic trip and thermal trip
functions to protect the unit when short-circuit and overload happens. D-type breaker is recommended to be
used.
(8) Wiring diagram attached on the unit is prevailed.
