1.
Switch off the pump and disconnect it from the electrical supply.
2.
Use a dry cloth and a soft brush to remove dirt and deposits from the fan cover.
6.5 Check the pump performance (service indicator)
The service indicator, (flashing ON 1s / OFF 1s) is triggered as a reminder to check the
performance of the pump. The service indicator will flash to indicate that a tip
‑
seal
change may be required (based on typical tip
‑
seal life). If after checking, the pump is no
longer achieving the required performance, we recommend you to replace a tip
‑
seal
(refer to
Service indicator codes on page 41
If the pump performance is within acceptable limits, or is performing satisfactorily, the
tip
‑
seal replacement can be delayed.
If operating a preventative maintenance plan, depending upon the particular regime, a
tip
‑
seal change can be carried out at this time irrespective of the pump performance.
To reset the service indicator, refer to
Service indicator codes on page 41
6.6 Replace the tip-seals
This information is applicable to the nXDS replacement tip seal kit that must be fitted.
Refer to
for ordering information.
A tip-seal replacement should be carried out to maintain or restore the pumps
performance. The frequency for replacing the pump tip
‑
seals is determine by the
following factors:
▪
The pump has reached a service interval. Refer to
(service indicator) on page 40
Replace the pump bearings (service indicator) on
▪
The pump is no longer achieving the required performance.
If the pump is no longer achieving the required performance prior to a service interval
being reached, we recommend you to follow the guide lines, refer to
failed to achieve the required performance on page 43
Note:
There may be a running
‑
in period after fitting your new tip
‑
seals. The performance
should improve over a period of 24 to 48 hours. If the pump performance does not
improve sufficiently after the running
‑
in period, please contact us for advice.
For information on how to replace the nXDS tip
‑
seals and Health and Safety, refer to the
nXDS replacement tip seal kit instruction manual A73502840 which is included on the
CD manual. Also refer to Youtube video at
https://www.youtube.com/watch?
6.7 Replace the pump bearings (service indicator)
The service indicator, (flashing ON 3s / OFF 1s) is triggered to indicate that a bearing
replacement service interval has been reached. Bearing wear cannot necessarily be
detected under normal operating conditions. This service interval is a recommendation
that a bearing replacement is required, this is especially useful if operating a
preventative maintenance plan.
