Failure modes to watch for
Every guide in the IMA Life IMA Lyofast library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Air pocket trapped in the shelf fluid circuit reducing flow through some shelf areas
Shelf fluid pump cavitation from low fluid level in the reservoir
Blocked shelf fluid inlet fitting reducing local flow
Shelf manifold valve stuck partially closed on an individual shelf
High moisture sublimation load overwhelming the condenser and passing moisture to the pump
Condenser bypass valve not fully closed, routing moisture-laden gas directly to the pump
Insufficient pump warm-up time before pulling vacuum on a wet load
Extended operation at low vacuum without running gas ballast to purge water vapor

How to fix condenser icing and reduced vacuum on an IMA Life IMA Lyofast lyophilizer
Reduced vacuum during drying usually means the condenser is overwhelmed with ice or the refrigeration system cannot maintain condenser temperature. Defrost the condenser and inspect the refrigeration circuit.
How to fix shelf temperature non-uniformity on an IMA Life IMA Lyofast lyophilizer
Non-uniform shelf temperature directly impacts product quality and cycle reproducibility. Check the shelf fluid circuit for flow restrictions and air pockets before adjusting setpoints.
How to fix vacuum pump oil contamination on an IMA Life IMA Lyofast lyophilizer
Milky pump oil means water vapor condensed in the pump. Change the oil, use gas ballast on warm-up, and check why the condenser is not capturing all moisture.
