2.4 Charging the Refrigerating Machine Oil
Caution Check page 203 [1. Precautions to Take before Replacement] before proceeding with the
following steps.
[If you have replaced the compressor:]
When the amount of remaining refrigerating machine oil in the old compressor is larger than the
initial charged amount (see
page 206 [2.2 Replacing the Compressor] ) of the replacement
compressor, charge the difference from the oil port (oil return line) after replacing the
compressor. When there is an oil leak, charge the leaked amount similarly.
[If you want to refill]
Charge the refill amount from the oil port (oil return line).
[If you have completely drained the refrigerating machine oil from the system:]
1. Perform evacuation through the high and low pressure side servicing ports or the stop
valves (liquid and gas). (When performed through the stop valves, they must be opened)
Turn ON the outdoor unit evacuation mode when performing evacuation.
2. For GYEQ30AN, charge the whole amount from the oil port (oil return line). For GYEQ20AN,
charge half amounts from both the oil port (oil return line) and the low pressure side
servicing port.
