
After vacuum, according to the diameter and length of the connective pipe of liquid side between
the indoor unit and outdoor unit, calculate the refrigerant replenishment quantity. The refrigerant
for replenishment is R410A.
Diameter of liquid-side pipe
Φ16mm (MOV-150HN1-R)

Note:
Please check and record the replenished quantity of the air conditioner.

Refrigerant leak precautions. This air conditioner uses refrigerant R22. R22 is safe refrigerant
which is harmless and non-flammable. The room for placing the air conditioner should have a
proper space. Even if refrigerant leakage occurs, the density threshold will not be crossed.
Additional measures may also be taken.

Density threshold: Density of the Freon gas that does not harm the human body. Density
threshold of R410A: 0.3kg/m

Calculate the total quantity of refrigerant to be replenished [A (kg)].
Total refrigerant quantity = refrigerant replenishment quantity upon shipment + additional
refrigerant replenishment corresponding to the pipe length.

Calculate out the indoor volume [B (m

Calculate out the refrigerant density:
[A (kg)] / [B (m

Measures against crossing of the refrigerant density threshold.
