X
List of Activities
Weekly
Monthly
(Note 1)
Yearly/Seas
Onal (Note 2)
Refrigeration circuit:
Check for any refrigerant leakage
X
Verify refrigerant flow using the liquid sight glass – Sight glass full
X
Verify filter dryer pressure drop
X
Verify oil filter pressure drop (Note 5)
X
Analyse compressor vibrations
X
Analyse compressor oil acidity (7)
X
Condenser section:
Clean water rinse condenser banks (Note 4)
X
Verify that fans are well tightened
X
Verify condenser bank fins – Comb if necessary
X
Notes:
1. Monthly activities include all the weekly ones.
2. The annual (or early season) activities include all weekly and monthly activities.
3. Unit operating values should be read on a daily basis thus keeping high observation standards.
4. In environments with a high concentration of air-borne particles, it might be necessary to clean the condenser bank more often.
5. Replace the oil filter when the pressure drop across it reaches 2.0 bar.
6. Check for any dissolved metals.
7. TAN (Total Acid Number) : 0,10 : No action
Between 0.10 and 0.19 : Replace anti-acid filters and re-check after 1000 running hours. Continue to replace filters until the TAN is lower
than 0.10.
0,19 : Replace oil, oil filter and filter dryer. Verify at regular intervals.
