02 BASIC FUNCTION
Auto(2-Step Cooling or Heat)
In Cool mode, the air conditioner will cool your room. You can adjust the temperature and the fan speed to feel cooler in hot
season.
• If current outside temperature is much higher than the selected indoor temperature, it may take time to bring the inner
temperature to the desired coolness.
• Quiet mode(
, ) makes the noise quieter during the operation of the indoor unit in the Cool mode.
Dry
The air conditioner in Dry mode acts like a dehumidifier by removing moisture from the indoor air.
Dry mode makes the air feel refreshing in a humid climate.
To activate the Dry mode, set temperature on the remote controller should be lower than indoor room temperature.
Fan
Fan mode can be selected to circulate your room. Fan mode will be helpful to refresh the stale air in your room.
Heat
The air conditioner heats as well as cools. Warm your room with this versatile appliance in the cold of winter.
• Fan may not operate for about 3~5 minutes at the beginning to prevent any cold blasts while the air conditioner is
warming up.

Evacuating the connected pipes
The outdoor unit is loaded with sufficient R-410A refrigerant. Do not vent R-410A into atmosphere: it is a fluorinated
greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975.
You should evacuate the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor.
It may cause reduction of cooling capacity and malfunction. Use Vacuum Pump as seen in the picture.
• W
hen installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first
before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle
abnormally high. It may cause explosion and injury.

Charging the refrigerant under conditions of liquid by using a liquid pipe
R-410A is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid. When recharging refrigerant from
the refrigerant cylinder to the equipment, follow the instructions below.
1. Before recharging, check whether the cylinder has a siphon or not.
There are two ways to recharge the refrigerant.
Cylinder with siphon
Cylinder without siphon
Siphon
 Charge the refrigerant standing the
cylinder upright.
 Charge the refrigerant turning the cylinder
upside down.
• If R-410A refrigerant is charged with gas, the composition of the charged refrigerant changes and the
characteristics of the equipment vary.
• During the measuring operation of refrigerant quantity added use electronic scales.
If cylinder doesn’t have syphon, upset it.

Leak test with nitrogen (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it’s responsible of
installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar
(gauge).
Leak test with R-410A (after opening valves)
Before opening valves, discharge all the nitrogen from the system and create vacuum according to page 46~48.
After opening valves, check leaks using a leak detector for refrigerant.
Pump down (before disconnecting the refrigerant connections for unit repair, removal or disposal)
Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit.
This operation must be carried out before disconnecting the refrigerant tubing in order to avoid refrigerant loss to the
atmosphere.
 Shut off the liquid valve with the Allen wrench.
 Turn the system on in cooling with fan operating at high velocity.
(Compressor will immediately start, provided 3 minutes have elapsed since the last stop).
 After 2 minutes of operation, shut the suction valve with the same wrench.
 Turn the system off and switch mains supply off.
 Disconnect tubing. After disconnection, protect valves and tubing ends from dust.
 Compressor damage may occur if run at a negative suction pressure.
