Safety information
>
Operate the vacuum pump only with oil filling.
>
Check the oil level through the sight glass every time before
starting the pump.
>
Check the pump’s oil level and the condition of the oil on a
regular basis,

see chapter: Oil level check on page 42 Oil level check on page 42 .
>
Use only oil of the recommended type. Other oils or operating
fluids may cause damage of the pump or danger.
>
Use special oils for the rotary vane pump, if extremely high
aging stability is required or if oxygen or other strong oxidiz ‑
ing agents are pumped,

.
>
Wear your personal protective equipment when working with
pump oils to avoid contact with the skin and possible irritations.
Prevent condensate return
Condensate in the outlet line can damage the vacuum pump.
Condensate must not flow back into the outlet or vacuum pump
through the hose line. Liquid must not accumulate inside the outlet
line.
>
Preferably route the outlet line with a fall from the outlet, i.e.,
running downward so that no backup forms.
Prevent foreign bodies inside the pump
Particles, liquids, and dust must not enter the vacuum pump.
>
Do not pump any substances which could form deposits
inside the vacuum pump.
>
Install suitable filters upstream of the inlet. Suitable filters are
chemically resistant, clog‑proof and have a reliable flow rate,
for example.
>
Replace porous vacuum hoses without delay.
Hazards during venting
If the manual gas ballast valve of the rotary vane pump is open,
a power failure or switching off the pump may cause accidental
ventilation of the pump or the vacuum system.
>
Install a solenoid operated gas ballast valve to avoid acciden ‑
tal ventilation.
