R-32 is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid. When recharging
refrigerant from the refrigerant cylinder to the equipment, follow the instructions below.
Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the

Cylinder with siphon Cylinder without siphon
siphon
Charge the refrigerant standing the
cylinder upright.
Charge the refrigerant turning the
cylinder upside down.
NOTE
If R-32 refrigerant is charged with gas, the composition of the charged refrigerant changes and the
characteristics of the equipment vary.
During the measuring operation of refrigerant quantity added use an electronic balance.If cylinder doesn’t have
syphon, upset it.
Calculating the quantity of refrigerant to add
The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor
