Replacement intervals should reflect the actual environment, contamination load, oil condition, and equipment guidance. Dust, heat, moisture, and maintenance history can shorten the practical service interval.
Before replacement, shut down the equipment and release residual pressure as required. Keep the installation area and new element clean so contaminants are not introduced into the circuit. Inspect the removed element and seals for evidence of abnormal wear or contamination.
Use a correctly specified replacement and record the date, equipment hours, oil condition, and observations. Maintenance records make recurring contamination or component wear easier to identify.
