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.
