Installation Procedure
Vacuum drying pipes and indoor units
• Use tools for R-410A to prevent the inflow of foreign substances and resist against the internal pressure.
• Use vacuum pump that allows vacuuming under -100.7kPa (5 Torr).
• Use the vacuum pump with the check valve to prevent pump oil from flowing backward while the vacuum pump is stopped.
• Completely close the liquid gas side service valve of the outdoor unit.
Charge additional refrigerant to the pipe
No
Perform vacuum drying again
Vacuum destruction
• Apply dry nitrogen gas to the pipe at pressure of
0.05Mpa.
No
Connect the manifold gauge to the liquid side pipe and gas side pipe
(when installing outdoor units in module).
When installing outdoor units in module, connect the manifold gauge to
liquid side pipe and the gas side pipe.
Perform vacuum drying of the liquid side pipe and gas side pipe (when
installing outdoor units in module) using a vacuum pump.
Make sure that check valve is installed to prevent pump oil from flowing
into the pipe.
While the vacuum gauge pressure is less than -100.7kPa (5Torr), perform
the vacuum drying for more than 1 hour and close the valve.
Vacuum pressure must be checked with the vacuum gauge.
After vacuum pump stops, check whether the pressure is maintained
within -100.7kPa (5Torr) for an hour.
Check for gas leakage
Yes
Over -100.7kPa (5Torr)
Yes
Pressure increase
※ If the pressure rises in an hour, either water is remaining inside the pipe or there is a leakage.
※ When the ambient temperature of vacuuming pipe is low (less than 0 °C), moisture might remain within the pipe. Therefore, pay
special attention to the pipe sealing in the winter.
