Take the cover off and take the obstacle away.
• Check if the air conditioner is operating in defrost mode. When the
ice formed in winter or the outdoor temperature is too low, the
air conditioner operates in defrost mode automatically. In defrost
mode, indoor fan stops and warm air does not come out.
• If the doors or windows are open, it may cause poor cooling
(heating) performance.
Close the doors and windows.
• Check if the air conditioner has just been turned on after stopping
cooling or heating operation. In this case, just fan will run to
protect the outdoor unit compressor.
• Check if the pipe length is too long. When the pipe length exceeds
maximum allowable pipe length, cooling (heating) performance

Evacuating the connected pipes
The outdoor unit is provided 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) = 2088.
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
operates with the service valve open, air can enter the system increasing pressure and may cause explosion and
injury.

installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 580 psig
(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 49~51.
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.
