Foreline pump maintenance: Inspect oil level and color (replace oil if degraded or black), check exhaust lines for damage/clogging/loose connections, and ensure the ballast valve is open (for NeoDry36E models). 2. Vacuum component checks: Clean sampling and skimmer cones if blocked, and inspect vacuum system seals for leaks. 3.
