This procedure is to be used to prepare for and perform draining oil from non-standard locations within the Ammonia Refrigeration System. OBJECTIVE: Maintenance Procedures are designed to give general guidance when performing maintenance activities. No procedure is appropriate for every situation. Maintenance Personnel should not attempt any procedure which is beyond their training. CONCERNS: Careful attention to Operating Conditions and valve positions are extremely important during this procedure. The primary incidents we are trying to prevent are injury to personnel. Additionally, our goal is to avoid the hazards associated with hydrostatic lock. REFERENCES: Additional information is available to personnel performing opening procedures.
