Table 5: Typical electrical codes in ZH compressors
5.15
Oil level
During the system development, adequate oil return in any operation should be checked
whatever the compressor model. For this purpose, sample compressors equipped with sight
tubes can be ordered from Emerson Climate Technologies. Oil return check test
recommendations are also available on demand from Application Engineering.
5.16
Oil stub
Compressors ZHI27K1P to ZHI46K1P are equipped with an oil Schraeder valve. The torque for
the insert of the Schraeder valve is 5.9 to 6.8 Nm.
For tandemization remove the insert with the Schraeder valve and braze the oil equilization line
into the stub.
