EMH 21-8 EANA

Monitor compressor oil temperature via temperature sensor gauge. Alarm should activate at 105°C with automatic shutdown at 115°C. Check oil cooler function and verify adequate cooling water flow (for water-cooled models) or air circulation (for air-cooled models).

Inspect oil filter visual condition and pressure drop indicator. Replace oil filter when receiver is empty following compressor shutdown. Check for oil color/clarity indicating age or contamination.

Verify receiver pressure gauge reading matches system design parameters. Inspect cyclone separator and multi-stage filter assembly for oil carryover or air leakage. Confirm oil-air separation efficiency via pressure differential readings.

Check TMV outlet temperature (target ~110°C in steady state). Verify TMV responds to ambient temperature changes and maintains proper delta-T. Monitor for condensation formation in discharge lines or receiver.

Inspect motor exterior for salt spray corrosion, moisture ingress, or mechanical damage. Verify motor IP55 certification still valid. Test motor insulation resistance with megohm meter (Class F motors typically require >1 MΩ at 500V). Confirm halogen-free cable integrity.
