▪ Do not touch or inhale the thermal breakdown products of uorinated materials
which may be present in the pump if the pump has been heated to 260 °C and
above. Fluorinated materials are safe in normal use but can decompose into very
dangerous substances (which may include hydrouoric acid) if they are heated to
260 °C and above. The pump may have overheated if misused or in a re. Safety
Data Sheets for uorinated materials used in the pump are available on request,
contact us or the supplier.
6.2 Maintenance plan
The plan shown in Table: Maintenance plan on page 26 details the roune maintenance
operaons necessary to maintain the pump in normal use. Instrucons for each
operaon are given in the secon shown.
More frequent maintenance may be required if the pump is used to pump corrosive or

Refer to Figure: Inlet strainer assembly on page 27. Disconnect the vacuum system
from the pump inlet port (item 3) and remove the centring ring and strainer
assembly (item 1) and the O‑ring (item 2). Inspect the centring ring and the O‑ring.
If clean, connue at Step 5. If not clean, connue at Step 2.
2.
Remove the O‑ring (item 2) from the centring ring and strainer assembly (item 1).
Do not allow the O‑ring to come into contact with the cleaning soluon.
3.
Wash the centring ring and strainer assembly in a suitable cleaning soluon and
allow it to dry.
