6-4. Recharging of Refrigerant
When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to
the following steps.
Connect the charge hose to packed valve
service port at the outdoor unit’s gas side.
Recover the refrigerant, and check no
refrigerant remains in the equipment.
(For refrigerant charging, see the figure below.)
Connect the charge hose of the vacuum
pump adapter.
Open fully both packed valves at liquid and
gas sides.
Place the handle of the gauge manifold Low in the
fully opened position, and turn on the vacuum
pump’s power switch. Then, evacuating the
refrigerant in the cycle.
When the compound gauge’s pointer has indicated
–0.1 Mpa (–76 cmHg), place the handle Low in the
fully closed position, and turn off the vacuum pump’s
power switch.
Keep the status as it is for 1 to 2 minutes, and ensure
that the compound gauge’s pointer does not return.
Set the refrigerant cylinder to the electronic
balance, connect the connecting hose to the
cylinder and the connecting port of the electronic
balance, and charge
liquid refrigerant.

Fig. 6-4-1 Configuration of refrigerant charging
1) Never charge refrigerant exceeding the specified amount.
2) If the specified amount of refrigerant cannot be charged, charge refrigerant
bit by bit
in COOL mode.
3) Do not carry out additional charging.
When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the
refrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the specified
amount is charged, and working pressure in the refrigeration cycle becomes abnormally high pressure, and
may cause a rupture or personal injury.
