Following precautions must be observed when the model is adapted to R407C.
(1) Tools and related components should be changed when handling a different kind of refrigerant in order to prevent mixing of different oils.
Gauge manifold and charge hose, particularly, should never be used after using them for R22.
(2) Charge cylinder should not be used. Otherwise, the refrigerant composition may change when charging R407C into the cylinder.
(3) Refrigerant should be charged in the liquid phase from the container. Charging the refrigerant in the gaseous phase could change the
refrigerant composition substantially.
(4) Volume of refrigerant to be taken out in the liquid phase from the container should be up to 90% of necessary quantity (in weight percent)
as a standard.
(5) Refrigerant should not be replenished even if a leakage is discovered because it could change the refrigerant composition substantially.
When a leakage is discovered, replace with new refrigerant in the specified volume. However, it could be replenished temporarily in case of
an emergency.
(7) Refrigerant charge amount
(a) Additional; charge amount
Notes (1) When the refrigerant piping length exceeds the length that additional refrigerant charge is not required, charge
additional refrigerant based on to calculated amount of refrigerant per unit piping length.
(2) The unit is holding charge type that all of the refrigerant is charged in the outdoor unit and in the indoor unit only
a small amount of refrigerant is filled for prevention of the air entry.
Calculation of amount of refrigerant to be charged in local piping
The amount refrigerant additionally charged in local piping depends on connection pipe size but not on indoor unit type.
