Inspecting the oil separator
1. Make preparations so that you can measure the gas pressures at the high-side pressure
servicing port and stop valve using a manifold gauge.
2. Make sure that the stop valve is open.
3. If the pressure at the high-side pressure servicing port (not at the stop valve) rises rapidly
after the system starts up in heating mode, chances are that the oil separator is clogged.
Replace the oil separator.

Inspecting the oil return pipe
• If, in the state shown in the figure above with the temperature at point A equal to or higher
than 60°C, the temperature at point B falls to or below 50°C during operation, chances are
that the pipe is clogged at (or downstream of) point B or the solenoid valve is faulty.
