5.6 Replace the tip seals
This instruction is applicable to the XDS35i
replacement tip seal kit (contained in minor service
kit, refer to Section 7.3.5) that must be fitted.
1 Refer to Figure 7. Switch off the pump,
disconnect the electrical supply and allow it to
cool to a safe temperature. Vent the pump using
the gas ballast control set to position 2.
2. Undo the fan connector (1).
3. Undo the six fixed scroll retaining screws (2).
CAUTION
Take care when removing the fixed scroll assembly
that once all fixings are released the assembly is not
dropped.
4. Carefully remove the fixed scroll assembly using
a lever in the slots provided to ease it from the
motor body as shown in Figure 8.
5. Gently move the fixed scroll assembly aside so
that the fan connector can be accessed. This is
fitted at the underside of the fan cowl and must
be undone in order to remove the fixed scroll
completely.
WARNING
Do not place fingers between the
scroll and the pump housing as they
could be injured if the motor is
