(5) Recharging

Be sure to charge the specified amount of refrigerant in liquid state using the service port of the wide tube service valve. The proper amount is listed on the unit's nameplate.

When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.

CAUTION

Never charge a large amount

of liquid refrigerant at once to

 

 

 

the unit. This may cause

 

damage to the compressor.

When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change. Thus, do not use the refrigerant if

the amount in the charging cylinder is less than 20%.

Also, charge the minimum necessary amount to the charging cylinder before using it to charge the air conditioning unit.

Example:

In case of charging refrigerant to a unit requiring

1.68lb. (0.76 Kg) using a capacity of a 22 lb. (10 Kg) cylinder, the minimum necessary amount for the cylinder is:

1.68+ 22 0.20 = 6.08 lb. (0.76 + 10 0.20 = 2.76 Kg)

For the remaining refrigerant, refer to the instructions of the refrigerant manufacturer.

If using a charging cylinder, transfer the specified amount of liquid refrigerant from the refrigerant cylinder to the charging cylinder.

Prepare an evacuated charging cylinder beforehand.

CAUTION

To prevent the composition

of R410A from changing,

 

 

 

never bleed the refrigerant

 

gas into the atmosphere

 

while transferring the

 

refrigerant. (Fig. 3)

Do not use the refrigerant if the amount in the charging cylinder is less than 20%.
