Charging the refrigerant under conditions of liquid by
using a liquid pipe
R410A 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 refrigerant.
Note
If R410A 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.
Charge the refrigerant standing
the cylinder upright.
Cylinder with siphon
Charge the refrigerant turning the
cylinder upside down.
Cylinder without siphon
