3-4. Recharging of Refrigerant

When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the following steps.

Recover the refrigerant, and check no refrigerant remains in the equipment.

Connect the charge hose to packed valve service port at the outdoor unit’s gas side.

Connect the charge hose to 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.

(For refrigerant charging, see the figure below.)

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.
