Equalized Oil Level Operation (Equalized Oil Level Between Twin Compressors) - Panasonic Urban Multi MX1R Series Service Manual

Function
1.6 Equalized Oil Level Operation
(Equalized Oil Level between Twin Compressors)
If using two compressors (8, 10Hp) connected in parallel, oil level equalizing is carried out for 5 minutes
when the cumulative running time of the standard compressor exceeds 2 hours in order to prevent lack of
oil caused by difference in pressure inside the dome due to drift, and then reverts to normal operation.
∗ If oil pressure equalization is not achieved during 5 minutes by stopping or step-down control, oil pressure
equalization is carried out when the compressor starts running.
With an inverter compressor operation, however, if the standard compressor remains off for 10 minutes,
the cumulative running time of the standard compressor is reset.
