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.
• When 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.

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.
