Chemical hazard: Chemical vapors and condensates deposited in the pump and the oil are harmful, avoid ingestion, inhalation, and skin contact. Wear nitrile gloves, goggles, and a respirator. |
 |
Burn hazard: Components of the vacuum pump can be very hot. Wear heat resistant gloves. |
Note: it is critical to change the pump oil according to the Maintenance Schedule. When the pump oil exceeds its recommended lifetime, acidification of the oil causes corrosion inside the pump, leading to pump failure and permanent damage.
¶ Vacuum Pump Oil Top-up
1. Open the oil-fill plug by hand. See image above for details.
2. Slowly refill the pump with Leybonol LVO210 oil (Leybold part no. L21001), until it reaches just below the maximum level indicated. A graduated cylinder with a spout or a funnel is recommended for this. See image in the following section.
3. Reinstall the oil-fill plug.
¶ Vacuum Pump Oil Change
1. Before performing an oil change, run the vacuum pump for about 30 minutes to allow it to warm up fully. If the pump is cold, it can be turned on through the Status Panel.
2. Once the pump has been warmed up, turn it off. Shut down and unplug the furnace.
3. Access the vacuum pump from the lower front door.
4. Place an oil catch pan below the drain port. See image below.
Warning: the hot oil will start pouring out immediately, make sure you have placed a suitable catch container underneath the drain port.
5. Open the oil-fill plug by hand. Open the oil-drain plug using an 8mm hex wrench. See image above (b) for details. The oil will start draining from the pump.
6. Once the oil stops flowing, tilt the pump forward to drain further. When it stops flowing a second time, replace the plug sealing ring with a new one and close the drain plug.
7. Refill the pump with 700-800 mL of Leybonol LVO210 oil (Leybold part no. L21001), until it reaches just below the maximum level indicated. A graduated cylinder with a spout or a funnel is recommended for this. See image below.
8. Replace the plug sealing ring with a new one and close the oil-fill plug.
Note: This oil was selected to provide maximum longevity and service intervals for your pump. Using other vacuum pump oils may require more frequent oil changes in order to protect your pump from wear and corrosion. This pump is only compatible with synthetic ester oil, equivalent to LVO210.
