1)
When the liquid and gas stop valves have not been opened, the system is under the vacuum:
① Refer to the left of the figure above; connect the R410A tank to the system.
② Turn on the R410A tank and the Hi-knob; charge the R410A refrigerant into the unit from the
liquid side stop valve. The Lo-knob should be closed completely.
③ Turn off the R410A tank and the Hi-knob immediately, when the adding refrigerant is enough.
④ Turn on the liquid and gas side stop valves in an anticlockwise direction slowly and completely.
2)
If the pressure of the system is too high to charge refrigerant, you can do as follow.
① Turn on the liquid and gas side stop valves in an anticlockwise direction slowly and completely.
② Turn on the power of the air conditioner, and set cooling mode, running more than 0.5h when
outside temperature is higher than 18℃ DB.
a)
Refer to the left of the figure above; connect the R410A tank to the system.
b)
Turn on the R410A tank and the Lo-knob; charge the R410A refrigerant into the unit from
the gas side stop valve. The Hi-knob should be closed completely.
c)
Turn off the R410A tank and the Lo-knob immediately, when adding refrigerant is enough.
③ Turn on the power of the air conditioner, and set heating mode, running more than 0.5h when
outside temperature is lower than 18℃ DB.
a)
Refer to the right of the figure above; connect the R410A tank to the system.
b)
Turn on the R410A tank and the Hi-knob; charge the R410A refrigerant into the unit from
the service port. The Lo-knob should be closed completely.
c)
Turn off the R410A tank and the Hi-knob immediately, when adding refrigerant is enough.

Caution！
◆ Make sure
the liquid and gas side stop valves are opened completely after the installation.
◆ Make sure the length of liquid pipe is exactly.
◆ Additional refrigerant charge must be measured exactly.
◆ Make sure that the refrigerant which charge into the unit is in liquid state.
◆
Please prevent the refrigerant leakage from your body when remove the charging hose.
◆
Please heat the refrigerant tank with hot water or hot air when the outside temperature is too
low. However, it must be forbidden to heat with fire directly, otherwise it may lead to
explosion.
