4.4 Lubricant System / Cooling Data
Table 1. Lubricant / Cooling Data.
4.5 Special Maintenance of Compressor Lubricant System
4.5.1 Deposits
Because the lubricant system operates under conditions of elevated temperature and pressure, solid or
semi-solid deposits may occur. However, proper installation, maintenance and filtration and lubricant
change intervals will greatly reduce the possibility of deposit formation.
Such deposits can interfere with operation of valves, filters and related cooling system equipment.
Minor deposits may be removed by flushing the system with an approved cleaning agent. Consult with
you Rogers factory representative for recommendations.
Completely drain lubricant while hot from every component that contains lubricant:
1. Replace lubricant filter and separator.
2. Fill machine with a factory-approved cleaning agent.
3. Operate the machine according to the cleaning agent manufacturer’s instructions, typically after
500 hours of operation.
4. Completely drain cleaning agent while hot from every component that contains lubricant.
A second flush may be required, as determined with laboratory testing.
1. Replace lubricant filter and separator.
2. Fill machine with new, clean lubricant.
