Charging the refrigerant and preventing refrigerant leakage

1.Measure the quantity of the refrigerant according to the length of the liquid side pipe. Then, Add fixed quantity of the refrigerant using a scale. (When the pipe length exceeds the standard pipe length of 5 m, charge the additional amount of refrigerant according to the exceeding length. Do not charge the refrigerant by assuming the quantity through pressure gage or by any other method.

However, if the pipe length is shorter than the standard length, you do not need to charge the additional refrigerant.)

2.Open the manifold gauge valve connected to the liquid side service valve and add the liquid refrigerant.

3.If you cannot add the refrigerant while the outdoor unit is stopped, open the gas side and liquid side service valve and add remaining refrigerant by pressing the cooling trial operation button.

4.After charging the refrigerant, completely open the spindle of the service valve (in counter-clockwise direction) on gas side pipe and liquid pipe side. (Do no push it further if the spindle hits the stopper.)

5.Tighten the cap of the service valve on gas side pipe and liquid side pipe as well as the cap nut for the charging port.

-- There could be slight refrigerant leakage when you open the spindle by using a wrench, but there's nothing wrong with the product.

-- Use a wrench that can easily apply force.
