Use this detergent oil to ensure the best operating performance by flushing dirt, impurities and water out of your vacuum pump. We recommend flushing out your vacuum pump at each oil change, before refilling the pump with vacuum oil. After draining old vacuum pump oil, add flushing oil until two-thirds full in the sight glass. Allow pump to run under vacuum for 3-4 minutes. Drain flushing oil well. To resume usual vacuum pump use, add fresh vacuum pump oil to recommended level in sight glass.
• IMPORTANT: Rio Flushing Oil is only intended to be left in the vacuum pump for the duration of the flushing process(3-4 minutes) as specified on the bottle. Please follow directions carefully.
