1-1 Refrigerant Refill Procedure

If connecting pipe of more than 5 metres is installed, additional refrigerant should be charged by extra metre. You don’t have to charge additional refrigerant up to 5 metres of connecting pipe.

1.

Remove the valve stem cap and service port of 3-way

 

valve.

 

 

 

 

 

 

 

 

 

 

 

 

2.

Connect the charging hose of low pressure side of

 

Manifold gauge to the packed valve having a charging

 

port(1/2” Packed valve) as shown at the right figure.

3.

Operate the unit at the cooling mode.

 

 

 

 

 

 

 

 

 

 

 

 

4.

Slowly open the valve of the low pressure side of

 

Manifold gauge counterclockwise until the low pressure

 

of manifold gauge indicates 4.8 to 5.5 kg/cm2 (68 a

 

78psi) at the high cool operation (1-unit operation) and

 

the standard temperature.

 

It is recommend that refrigerant should be slowly put in.

 

If the refrigerant is put in too quickly, compressor will be

 

damaged.

 

 

 

 

 

 

 

 

 

 

 

 

5.

Stop operation of the air conditioner.

 

 

 

Additional refrigerant charge (R22,g)

•When length of the pipe is over 5u by the unit, you should charge

the refrigerant Formulas
