SERVICEPROCEDURES

Maintenance ofLubricant Quantityin
Compressor

The lubricant inthe compressor circulatesthroughthesystem
with therefrigerant. Addlubricant tocompressor whenreplac-
ing any component orafter alarge gasleakage occurred. Itis
important tomaintain thespecified amount.
If lubricant quantityisnot maintained properly,thefollowing
malfunctions mayresult:
• Lack oflubricant: Maylead toaseized compressor
• Excessive lubricant:Inadequate cooling(thermal exchange
interference)
